“Is this batch of textile goods subject to RoHS?” — the question sounds simple, but it is the reason why many businesses make incorrect documents in both directions: either overdoing it (wasting money on non-applicable requirements), or underdoing it (omitting the regulatory framework that actually applies).

This article states the principles for determining the scope, compares the applicable framework for each product group and points out cases of “having electricity but not falling under RoHS”.

1. Original principle: RoHS only applies to electrical and electronic equipment

RoHS applies to devices that require electric current or electromagnetic fields to operate. Three decisive questions:

1. Does the product require electricity or electromagnetic fields to operate?
2. If so, is the part that creates that function a separate device or just an accessory?
3. Is the final product in the group regulated as separate electrical and electronic equipment or just a part of another product?

If the first answer is “no”, RoHS does not apply — regardless of whether the product has a technical label or not.

2. The framework applies to each product group

Worth noting: for shoe leather, the requirement for hexavalent chromium — which is often associated with RoHS — comes from the EU substance restriction framework for leather products, not RoHS. This is a common source of confusion when a business makes both leather goods and electronic goods.

3. Three cases of “having electricity but not under RoHS”

Pragmatic rule: if in doubt, ask the customer in writing what framework applies to the end product, rather than guessing from the product name.

4. Why do customers still ask about RoHS for textiles?

• General purchasing requirements: Many corporations use a request form for every product group, including the RoHS section.
• Broad interpretation: “RoHS” is used as a general name for a group of substance restriction requirements.
• There is an electrical part in the product: Many modern textile items have small electronic modules.
• Avoid risks: Customers want to be sure the supplier understands the scope properly before signing the contract.

The appropriate response is not “don’t have to do it” but: confirm whether the product has an electrical or electronic part, state which framework actually applies, and propose the corresponding set of documents.

5. Five questions you should ask your customers

1. Does the product have electrical and electronic functions, and is that part sold separately?
2. Is the main target market EU, US, Japan or many markets?
3. Does the customer have a separate substance request form?
4. Does the product come into direct contact with the user’s skin?
5. Do customers require specific standards beyond legal regulations?

6. Frequently asked questions

So what documents do textile and garment products need?

Usually a test report requested by the customer for restricted substance groups applicable to textile materials, accompanied by a manufacturer’s declaration. Specific content depends on the market and customers.

What if the customer still requires a RoHS report?

Can be discussed to agree on appropriate standards for materials. If the customer requests it, it can be tested according to the restricted substance list for risky materials and clearly stated in the scope of application report.

Are shoe leather tested for hexavalent chromium?

Yes, but according to the substance restriction framework for leather products, not according to RoHS. Applicable limits and test methods are also different.

What about handbags with wireless charging modules?

The charging module has its own electrical function, so that part falls under the scope of electrical and electronic equipment. Need records for electrical parts, and records for leather or fabric materials.

How do you know if an electrical accessory is a separate device or an accessory?

Based on the actual function and how it is marketed: if the accessory can operate independently and is sold separately, it is likely to be considered a separate device.

7. Conclusion

RoHS only applies to electrical and electronic equipment. Textiles, footwear and toys without electrical functions are outside the scope of RoHS, but must still meet the target market’s other substance restriction frameworks.

Three things to do: clearly determine whether the product has electrical or electronic components; Record the applicable frame for each product code in the file; and confirm in writing with the customer before testing begins.

The CE mark appears on nearly every electronic device sold in Europe, but very few businesses can answer exactly on what legal basis the mark is applied. And that is the point where the goods are held back.

This article explains what CE marking actually is, what directives commonly apply to electronics, why WEEE is not included in the CE marking directives, and five common mistakes.

1. The CE mark is not a certification

CE marking is the result of the manufacturer’s (or authorized representative’s) self-assessment and declaration that the product meets all applicable directives. This is not a third-party certification for most common electronic products.

Three important consequences:

• The CE mark is only correct when the documents are correct: Without corresponding documents, the CE mark is invalid.
• The CE mark covers many directives at the same time: The lack of an applicable directive means that the CE marking is invalid for the entire product.
• Responsibility belongs to the person who affixes the seal: usually the manufacturer, or the importer when the product comes from outside the EU.

2. Directives often apply to electronic goods

Point to note: many electronic products have small capacity or use low DC power not covered by LVD. Then it is still necessary to meet safety requirements, but the basis of assessment lies in general product safety regulations, not LVD.

3. Why is WEEE different?

In other words: WEEE is a parallel obligation but not a “leg” of the CE marking. Businesses must still meet both, but do not use WEEE records to prove CE marking and vice versa.

4. Five common mistakes

5. How to determine enough “legs” before stamping

1. Determine the nature of the product: Is there an electronic circuit, is there a radio function, what is the operating voltage?
2. List applicable directives According to each of those characteristics, record it in the records according to the product code.
3. Prepare separate documents for each directive: Test reports, evaluations, design documents.
4. Check obligations beyond the CE mark: WEEE, registered by country, requires private label.
5. Sign the unified declaration of conformity clearly state the applicable directives.

6. Frequently asked questions

Is third-party certification required for CE marking?

For most common electronic products, no. Manufacturers make their own assessments and take responsibility. Some product groups have their own requirements for designated organization participation.

Does a product using a 5V battery have to be made LVD?

Normally not within LVD range if operating outside the applicable voltage range. However, it still must meet general product safety requirements, EMC and RoHS.

Is WEEE needed to sell products on e-commerce platforms?

Yes. E-commerce platforms in the EU often require proof of WEEE registration and responsible person in the EU, in addition to CE records.

If I only sell goods to businesses, do I have to have CE stickers?

It still applies if the product falls within the scope of the directives, whether sold to businesses or consumers. CE marking is required to be attached to the product, not to the sales channel.

How long do CE records stay?

According to the time limit specified by each directive; with RoHS, it is ten years from the time the product is brought to market. The longest period of the applicable directives should be applied.

7. Conclusion

CE marking for electronic goods is the result of several directives at once: electromagnetic compatibility, electrical safety (if within the applicable voltage range), radio equipment (if applicable), RoHS and eco-design requirements where applicable. WEEE is a parallel obligation but is not included in the group of CE marking directives.

Three things to do: create a list of directives applicable to each product code; Prepare separate documents for each directive in the same dossier set; and check the obligations beyond the CE mark before delivering the first batch.

Recalls due to RoHS rarely originate in the test room. It often starts with a customer email, a request from a market surveillance agency, or a shipment being held at the border — then the business goes looking for the cause.

This article analyzes five typical situations in the same framework: what happened, what were the early signs, what went wrong, and how to prevent it.

1. Five typical situations

Situation 1: Changing material suppliers without notice

Situation 2: Using the same records for many product codes

Situation 3: Old inventory components mixed into new batch

Scenario 4: Input recycled plastic contains old flame retardants

Situation 5: Plating from a processing supplier

2. Summary table: which step is wrong?

3. Five-step process when detecting limit exceedance

1. Localize now: Determine batch, product code, time period and quantity delivered.
2. Evaluate the scope of influence: Trace materials by batch and supplier to know which batches are affected.
3. Find the root cause: distinguish between random errors and systematic errors; Check for material change traces.
4. Corrective action: Replace materials, retest, update technical records and declare conformity.
5. Notice: Notify customers and, when necessary, competent authorities according to the level of impact.

4. Six points of prevention

5. Frequently asked questions

When the limit is detected, must all production be stopped?

Not necessarily. Need to localize first: stop the affected part, continue the unrelated part if there is evidence. The decision is based on the retrieval range.

Must all materials be retested when one material exceeds the limit?

No. It is necessary to retest the relevant material and check to see if that material is present in other product codes.

How should customers request compensation?

Based on contract terms and sub-vendor responsibilities. This is why change notification and limit liability provisions need to be negotiated in advance, not after the incident.

How long does it take to complete an investigation?

Depending on the complexity of the retrieval, there should be an internal milestone as soon as it is discovered: localize within a few days, determine the scope and cause within one to two weeks.

Is there any way to detect limit exceedance early without needing to continuously test?

Yes: control by material risk level, screen inputs by batch, compare with standard samples, and track supply change traces. Most incidents have previous signs.

6. Conclusion

The above five situations are different in appearance but have the same root cause: uncontrolled change — material change, product code change, inventory change, plastic source change, processing process change.

Three things to do: include a change notification clause in every supply contract; Review compliance documents whenever there are new details or suppliers; and build traceability according to production batches so that when there is a problem, it can be localized within the day, not within the month.

If I had to point to a single reason why electronics have exceeded the RoHS limit in recent years, the answer is usually cables: PVC casings containing phthalate plasticizers. This is a hot spot for three reasons at the same time — the large volume of plastic, the widespread use of plasticizers, and the group of substances that are limited by route so many old reports have not been included.

This article analyzes the mechanism, application roadmap, and how to control cables in the supply chain.

1. Why are cables a phthalate hot spot?

Hard PVC cannot be used for cable sheathing because it is too brittle. To be flexible, manufacturers add plasticizers in large proportions – some up to tens of percent by weight. The most common and cheapest group of plasticizers includes phthalates which are on the restricted substances list.

Three factors make the risk higher than other materials:

• Large additive ratio: Plasticization accounts for a significant proportion, so the concentration of restricted substances in a homogeneous material can easily exceed the limit.
• Many types of cables: One product can use many types of cables from many different suppliers.
• Recycled plastic: Cables or recycled plastics may carry plasticizers from unknown sources.

2. Group of related substances

Point to note: cable is where many groups of substances meet in the same material. So when testing cables, it’s a good idea to test for phthalates, flame retardants, and heavy metals — not just one group.

3. Roadmap for applying phthalate group

Practical consequence: many RoHS test reports predate the phthalate application milestone, although they are still “in time” in the sense of time. Businesses need to check whether the content of the report includes this group of substances, not just the date of issue.

4. How to control cables in the supply chain

1. Make a cable list by detailed code: Includes both separately purchased cables and pre-installed cables in purchased modules.
2. Requires material declaration for each type of cable cover, clearly state the plasticizer group and the fireproof group.
3. Try confirming according to mass spectrometry method for phthalate group, for first batch and periodically.
4. Controlling recycled plastic: If the cable jacket uses recycled plastic, put it in the high-risk group and control each batch of raw materials.
5. Internal labeling for materials meets: Helps warehouses and factories avoid mixing unconfirmed materials.

5. Alternative material selection and trade-offs

What needs to be avoided is changing materials just to achieve one criterion and then ruining another criterion. With cables, three criteria often have to be weighed at the same time: fire safety, mechanical durability and electrical properties.

6. Frequently asked questions

Are RoHS reports from before the phthalate adoption milestone still valid?

Formally it may be there, but in terms of content it does not include the phthalate group unless tested. Need to try supplementing this group of substances, especially with products that use a lot of PVC.

Are alternative plasticizers restricted by RoHS?

May not be on the restricted list, but still needs to be checked according to other requirements such as REACH and customer’s own requirements.

Does the cable purchased with the module have to be tested separately?

Yes. This is a material included in the end product and therefore within the scope of assessment, even if purchased by the module supplier. Material data for the entire cable section should be requested.

What if the limit is only exceeded in a small section of cable?

The limit applies to each homogeneous material, regardless of length or mass. So it still has to be handled.

Is there a way to quickly test for phthalates at the factory?

There is no reliable hand-held screening method for phthalates because they are organic compounds. Control is mainly based on material declaration and periodic testing using mass spectrometry methods.

7. Conclusion

Cables are a phthalate hot spot because the PVC sheath contains a large proportion of plasticizers, and this group of substances is only applied by route so many older reports do not include it. Good cable control eliminates one of the most common causes of overshoot.

Three things to do: check the content of the old report to see if there is a phthalate group; Requires declaration of cable cover according to detailed code; and evaluate all three criteria when switching to alternative cable jacket materials.

In the mechanical and electronic industry, the chromium passivation layer is the most underrated Cr(VI) hot spot. Many factories carefully inspect welds and plastics but ignore plating on metal parts — where hexavalent chromium was once commonly used to increase corrosion resistance.

This article explains the mechanism, the four most common sticking situations, and how to develop practical controls for plating.

1. What is chromium passivation layer and why is it related to RoHS?

Steel or zinc parts are often plated and then surface treated to increase corrosion resistance. Traditional surface treatment uses hexavalent chromium, creating a characteristic golden or rainbow color.

Hexavalent chromium is on the RoHS restricted substances list. Meanwhile, trivalent chromium — the form used in replacement passivation layers — is not part of the restricted group. These two forms have the same chromium element but their properties and legal obligations are completely different.

This is the source of nearly all the confusion about chromium in RoHS filings.

2. Why does XRF report high chromium without concluding anything?

The screening device only measures total chromium, regardless of valency. Consequences:

• False alarm: The trivalent chromium passivation layer results in increased total chromium, causing unnecessary concern.
• True omission: A very thin coating of hexavalent chromium may give unremarkable total chromium results, especially when the sample matrix is steel.
• Unable to locate: The total result does not indicate whether the chromium is in the plating layer or in the base alloy.

Therefore, with plating, the conclusion must be based on the method of determining valence, not on the results of elemental screening.

3. Four situations where Cr(VI) is often stuck in the plating layer

4. How to control reality

1. Make a detailed catalog with overlays: All metal parts are plated, passivated or surface treated.
2. Overlay process declaration required from the supplier, with a commitment not to use hexavalent chromium.
3. Test confirmation for the first batch and periodically by chemical determination method for metal coatings.
4. Use the rapid point-of-care test for screening only: Positive results need to be confirmed, negative results are not enough to be conclusive.
5. Change control: Any change in processing supplier requires retesting the first batch.

5. Frequently asked questions

Is the yellow coating definitely hexavalent chromium?

Not sure. Color is for reference only, not evidence. Some coating systems that do not contain hexavalent chromium remain yellow. Conclusions must be based on analysis.

If the result of determining chemotherapy is higher than the limit, how to handle it?

It is necessary to determine the scope of influence: which batch, which detail, from which supplier. Then ask the supplier to switch to a passivation layer that does not contain hexavalent chromium and retest the first batch before resuming production.

Can an exemption be used for chrome plating?

Some applications have exemptions, but they are narrow in scope and have an expiration date. The exemption should not be assumed for normal plating; need to compare the list of exemptions according to the correct application.

Is a rapid test with an indicator solution acceptable as evidence?

Usually not enough to conclude compliance records, but useful for internal control. Positive results should be confirmed analytically, negative results should be periodically cross-checked.

Is it true that the supplier says the plating “does not contain chromium”?

Need to clarify: completely chromium-free, or just hexavalent chromium-free. Many passive layers still contain trivalent chromium and that is completely RoHS compliant.

6. Conclusion

Cr(VI) in the chromium passivation layer is a persistent hot spot for three reasons: the risk lies with the procedureing supplier, the screening results do not distinguish valence, and switching to alternative coatings affects corrosion resistance.

Three things to do: catalog all parts with surface treatment; request process commitment from the procedureing supplier; and try to confirm chemotherapy for the first batch and periodic batches instead of relying on total chromium results.

If you have to choose a substance that causes electronic businesses to exceed the RoHS limit the most without knowing it, the answer is usually cadmium. The reason is simple: cadmium has a limit ten times stricter than other substances, and it often enters the product as an impurity, not as the intended ingredient.

This article analyzes why cadmium is difficult to control, five common sources of contamination, and how to develop a cadmium control program in factories.

1. Why is cadmium the most difficult substance on the list?

For the first four substances on the restricted list, the commonly remembered limit is 0.1%. With cadmium, the limit is much tighter, so the control method must also be different: the same testing procedure that is sufficient for lead may not be adequate for cadmium.

2. Five common sources of cadmium contamination

Common point: cadmium is almost never a material that is intentionally declared in records. It comes from impurities or from additives that are not communicated through the supply chain.

3. Why are screening results not sufficient for cadmium?

Handheld screening equipment is useful for input control, but with cadmium there are three problems:

1. Detection Limit: At a tight limit, the screening error can be larger than the distance from the result to the limit.
2. Influence of sample background: Brass alloy or plating can distort results in both directions.
3. Non-representative measurement locations: Cadmium may be concentrated in a layer or small area that point measurements do not reach.

Therefore, the principle should be applied: screening to detect, quantitative analysis to conclude. When the screening results are close to the limit or the material falls into the risk category, a precise analytical method must be turned to.

4. Cadmium control program in 5 steps

5. Frequently asked questions

Does cadmium have the same limit as other substances?

No. Cadmium has a stricter limit than the remaining substances on the restricted list, so it needs a separate control method.

Does brass always contain cadmium?

Not always, but this is a high-risk group of materials because cadmium can be an impurity. Need to check by batch and by supplier.

Is there an alternative to cadmium pigment?

There are many alternative colorant systems, but color fastness and processing conditions must be checked. This is a change that requires approval of new materials, not just simple replacement.

Can materials be mixed to dilute the concentration?

No. Dilution to fall below the limit is an act of evasion of obligations, and is also not a guarantee because the limit is calculated based on the homogeneous material of the actual part.

If only one small detail exceeds the limit, does it have to be handled?

Yes. The limit applies to each homogeneous material, regardless of the mass of the part in the product.

6. Conclusion

Cadmium is the most difficult substance on the restricted list because the limit is tight, the contamination source is an impurity, and screening is limited. Controlling cadmium is almost synonymous with controlling all RoHS records.

Three things to do: map cadmium risk materials in products; require suppliers to declare cadmium concentrations separately instead of just certifying “pass”; and move to quantitative analysis for all cases near the limit.

Solder joints are the number one RoHS hotspot in the electronics industry, as this is where lead was once most commonly used. The lead removal roadmap has been going for nearly two decades, but in reality there are still many traps that cause shipments to exceed the limit.

This article presents the transition roadmap, technical changes when switching to lead-free alloys, and six common traps in manufacturing.

1. Why is the weld a hot spot?

Lead in solder joints is the most common application of lead in electrical and electronic equipment: lead-tin solder alloys are easy to use, low melting temperature, flexible solder joints and low cost. When RoHS was born, the electronics industry was forced to switch to lead-free alloys on a global scale.

Three sources of lead need to be distinguished:

• Lead in solder alloy: main source, replaceable with lead-free alloy.
• Lead in tin plating: Corrosion resistant and solderable, replace with pure tin or barrier tin plating.
• Lead in base alloys and exemptions: Some lead-containing alloys are exempt at certain concentration levels, for example lead in brass alloys or aluminum alloys at permissible impurity levels.

2. Roadmap to remove lead and replace alloys

Point to remember: exemptions for lead in solder joints still exist, but only for specific applications, usually very high-melting temperature soldering or specific product groups. No exemption shall be inferred for ordinary welds.

3. Six traps when switching to lead-free alloys

4. Affects reliability

A consequence to note: when switching to lead-free alloys, reliability criteria must be re-evaluated, especially for products subject to vibration, high temperatures or thermal cycling.

5. Lead sources other than solder joints

6. Frequently asked questions

Is every solder joint required to be lead-free?

Most consumer electronics must use lead-free alloys. However, there are still exemptions for some specific applications, for example welding at very high temperatures or specific product groups. Need to check the list of exemptions according to the correct application.

Is the exemption for lead in solder limited?

Yes. Waivers have expiration dates and can be renewed in stages. Therefore, businesses must monitor, the exemption cannot be considered permanent.

How do you know if a shipment is cross-contaminated with lead?

Check incoming welding supplies, clean equipment when changing, and periodically take weld samples. If lead is detected at unusually low levels, it is necessary to review the entire flow of materials in the production line and repair area.

Is pure tin plating safe?

In terms of RoHS, it is satisfactory, but it is necessary to control the phenomenon of tin filament growth. The common way is to use a nickel barrier layer underneath or use matte tin with temperature control.

Is SAC305 alloy the only choice?

Are not. There are many different lead-free alloys, each with its own trade-offs in terms of temperature, durability, and cost. The choice depends on the reliability requirements of the product.

7. Conclusion

Removing lead from the solder joint is more than just replacing a consumable: it entails thermal profile changes, reliability reassessment, cross-contamination control, and exemption management. Lead can still be present in plating, alloys and repair supplies — not just solder joints.

Three things to do: control welding supplies in both the line and the repair area; Review the list of exemptions according to the correct application and expiration date; and reassess reliability each time the solder alloy is changed.

Electronic goods detained at EU border gates because of RoHS are almost never due to complex technical errors. In most cases, the cause is very basic documentation and labeling errors — and completely preventable before the container is closed.

This article lists the seven most common practical errors, signs of an inspection, how to prevent them, and a short pre-shipment checklist.

1. Seven mistakes and how to avoid them

2. Why are profile errors more dangerous than technical errors?

With a technical error, businesses can prove it through testing and batch processing. With document errors, businesses often lose the right to explain from the beginning: goods are held, time is pushed back and storage costs are incurred while waiting for additional documents.

Three common root causes:

• Documentation is located in many places: Technicians keep test reports, businesses keep contracts, warehouses keep labels — no one has a complete set of records.
• Outdated documentation: old report, materials have changed but records are not updated.
• No one takes overall responsibility: Each department does its part, there is no final reviewer.

3. 10-point checklist before shipping

4. Substance groups are often overlooked when tested

5. Frequently asked questions

Does customs do RoHS inspection?

Testing depends on each country and each batch. However, when in doubt, businesses will be required to present a declaration of conformity and supporting documents. Therefore, the application package needs to be ready to send immediately.

Is a test report issued by a testing laboratory in Vietnam acceptable?

Acceptable in principle if the testing laboratory has appropriate capacity and correct methods. It is important that the report properly covers the material of the delivery and has clear identification.

If the goods have been detained, how will they be handled?

Immediately prepare additional documents: declaration of conformity, valid test report, label photo and product description. In some cases, additional testing may be required at an accredited testing laboratory.

Is a test report required for each batch?

Not required by law. But businesses need evidence that the products sold are still as designed and assessed for compliance.

How do you know which product codes are most susceptible to inspection?

Prioritize according to batch value, material complexity, substance group risk level and history of each customer or market. High-risk materials in large quantities are the most susceptible to inspection.

6. Conclusion

Goods detained because of RoHS are mainly due to records and labels, not due to analytical machinery. Therefore, the most effective prevention lies not in the testing room but in the pre-shipment inspection process.

Three things to do: assign one person to be responsible for final review of each batch; Check the list of directives applicable to each product code; and compare the name and product code between the test report, label and bill of lading before closing the container.

RoHS is a regulation that restricts substances in products. But in Europe, a new layer of requirements is being developed in parallel: requirements on eco-design and product information, which include Product passport no. This layer of requirements does not replace RoHS, but will change the way businesses demonstrate and retain regulatory data.

This article describes the two parallel layers of obligations, what changes in filing practices, and what businesses should prepare for now.

1. Two layers of obligations: substance restriction and ecological design

Point to remember: these two layers overlap, are not mutually exclusive. The product must still meet RoHS, and may also have to meet eco-design requirements if it belongs to a priority product group.

2. What will digital product passports change?

The core idea: instead of a stack of paper documents sitting in an internal file, product information is organized into structured data, tied to product codes, that can be retrieved digitally.

With RoHS compliance, this means:

1. Material data needs to be standardized from the beginning: material code, detail code, data source, version.
2. Data must be linked to specific products: not just in yearly folders.
3. Evidence needs structure: Test reports and material declarations are organized by data fields instead of separate files.
4. Information may be released publicly or at a limited level depending on the type of data and specific regulations.

3. Five practical impacts on businesses

4. Things that do NOT change

• RoHS remains in effect: Substance lists, homogeneous material limits and exemption mechanisms remain independent obligations.
• The manufacturer’s responsibility remains with the manufacturer: cannot switch to a supplier or e-commerce platform.
• The declaration of conformity still requires: Digitized data is an organization, not a substitute for liability.
• The principle of pre-market evaluation remains the same.

5. Four things to do immediately

1. Standardize material codes and detail codes throughout the production and purchasing system.
2. Convert regulatory documents into data format: At a minimum, there is a table linking the part number, material, supplier and test report.
3. Include data terms in supply contracts: Requires material declaration in data form with clear fields.
4. Track the roadmap by product group: Determine in advance which group your product belongs to and which milestones will apply.

6. Frequently asked questions

Does a digital product passport replace a declaration of conformity?

No. Declaration of conformity is a legal document signed by the manufacturer; A digital product passport is a way to organize and publish product information. The two things serve two different purposes.

Do small businesses have to worry right away?

There is no need to prepare large infrastructure right away, but you should start standardizing material codes and organizing records according to product codes. These are two useful things for all current compliance requirements.

Is material data publicly available?

Depending on the type of data and specific regulations: some information is public, some is only for authorities and supply chains. Businesses should classify data as soon as it is collected.

Does the new requirement apply to components sold separately?

The scope depends on each group’s product definition in the work plan. With components, pressure often comes indirectly through data requests from customers manufacturing the end product.

Where should I start if I don’t have anything yet?

Start from material data: create a table linking product code, detail code, supplier, test report and effective date. This is common ground for both current RoHS and upcoming information requirements.

7. Conclusion

RoHS asks about substances in products; The class requires eco-design and a digital product passport asking about product features and information. The two layers are parallel, not interchangeable — and require the same thing: material data standardized by product code.

Businesses that have organized records by product code and have a materials database will move to the new stage much more easily. Any business that still leaves records scattered in folders and emails will have to start over.

In the technical records of many electronics factories, besides RoHS, there is often another requirement that sounds very similar but is actually completely different: halogen-free. This requirement is not covered by RoHS, but appears frequently in supply contracts, especially with customers in Europe, Japan and the automotive industry.

Confusion between these two requirements leads to two types of errors: receiving halogen-free claims but reporting with RoHS results, or vice versa, wasting halogen testing costs when customers only ask about restricted substances.

1. What is halogen-free?

Halogen is a group of elements including fluorine, chlorine, bromine, and iodine. The “halogen-free” requirement sets a limit on the total content of this group in the material, most commonly according to the levels:

• Chlorine must not exceed 900 parts per million in materials.
• Bromine not more than 900 parts per million in materials.
• The sum of chlorine and bromine is not more than 1,500 parts per million.

These three levels are a common expression in printed circuit board material standards and in many customer requirements. There are also other ways to say it such as “low halogen” (looser limit) or “no added halogen” (only a commitment to not actively add, no background limit).

With cables, halogen-free requirements are often accompanied by requirements on smoke and fire emissions, because the main purpose is to reduce corrosive gases and toxic fumes in fires.

2. Why is halogen-free NOT included in RoHS?

In short: RoHS banned some compounds bromine; halogen-free limited total amount halogen. A material can meet RoHS but still not be halogen-free, and vice versa.

3. Why do customers still demand halogen-free?

1. Fire safety: Halogen-containing materials produce corrosive gases and toxic fumes when burned; Especially important requirements for cables in buildings, medical equipment, and vehicles.
2. Industry requirements: Some industries have their own standards for halogen-free materials for components and cables.
3. Green purchasing policy: Many corporations include halogen-free in the list of purchasing requirements with RoHS and REACH.
4. Market orientation: used as a point of environmental competition, although there is no mandatory legal basis.

4. How to check halogen-free?

Note: the rapid screening method is useful for input control, but to conclude on a halogen-free limit requires measurement of total halogen using a suitable method.

5. Five points to consider when receiving a halogen-free request

The last point is most often overlooked: switching to halogen-free materials can reduce fire resistance if the correct alternative material system is not chosen. It is necessary to evaluate both indicators at the same time.

6. Frequently asked questions

Does achieving RoHS mean achieving halogen-free?

No. RoHS only restricts certain bromine compounds. Materials with other bromine flame retardants still meet RoHS but exceed the total bromine limit of the halogen-free requirement.

Is there any law mandating halogen-free?

There are no general mandatory requirements for all electrical and electronic products. This requirement mainly comes from contracts, industry standards and customer purchasing policies.

Is XRF measuring bromine enough to conclude halogen-free?

Not enough, because XRF does not indicate chlorine content and cannot distinguish compounds. Use XRF to control input, but need total halogen measurement for conclusion.

Is TBBPA restricted by RoHS?

Not on the RoHS restricted substances list. However, this is a bromine-containing compound so it will be included in the total bromine when evaluating the halogen-free requirement.

If a customer requests “no added halogen”, what should be done?

This is a different requirement from the halogen-free limit. It is necessary to clarify whether the customer wants to commit to not actively adding halogen compounds or wants to limit the total content, and then choose the corresponding evidence.

7. Conclusion

Halogen-free and RoHS are two essentially different requirements: one is a legal limit according to the substance list, the other is a technical limit according to the total amount of halogens. Both are important, but do not replace each other.

Three things to do: clearly state the limit and material range when receiving halogen-free requests; use total halogen measurements to conclude instead of just screening for bromine; and re-check the fire resistance index each time switching to alternative materials.
