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
| # | Error | Signs when checking | How to room |
|---|---|---|---|
| 1 | There is no declaration of conformity or product mismatch content | Enterprises only present test reports, no written statements | Prepare a declaration of conformity according to product code, with a responsible person signing |
| 2 | Apply CE mark when documents are not complete | Only RoHS test results are available, lacking other directives applicable to the product | Review all applicable directives before applying the seal |
| 3 | The test report does not include enough materials | The report only has a few materials but the product has more materials | Completely disassemble and compare the material list with the report |
| 4 | Use screening results as conclusive evidence | There is only a screening result sheet, no standard analysis method | Clearly determine which results are used for conclusion and which results are only for control |
| 5 | The label lacks identifying information | Missing manufacturer name, missing responsible person within the EU, or missing identification code | Check labels according to identification requirements before mass printing |
| 6 | There is no responsible person in the EU | Goods come from abroad but there is no importer or authorized representative | Clearly state in the contract and on the responsible party label |
| 7 | Documents do not match between documents | The product name, product code or parameters on the report are different from the label and bill of lading | Standardize the way names and product codes are written in all documents |
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
| # | Content of inspection | Evidence |
|---|---|---|
| 1 | Confirm the directives that apply to the product code | List of directives by product code |
| 2 | The declaration of conformity remains true for the current product version | The document has the date and signer |
| 3 | Full homogeneous material list | Material take-off sheet |
| 4 | The test report adequately covers the hazardous materials | Compare materials with reports |
| 5 | Supplier’s material declaration is valid | Declaration with date |
| 6 | There are no longer any old parts in stock | Delivery note, batch trace |
| 7 | The label has enough identifying information | Actual label photo |
| 8 | CE mark in correct position, correct size | Product photo |
| 9 | Name and product code match between documents | Compare three documents |
| 10 | There is someone responsible in the target market | Contract or authorization document |
4. Substance groups are often overlooked when tested
| Substance group | Why is it easy to miss? | How to check |
|---|---|---|
| Phthalate group | Only applicable according to the roadmap for each product group, so the old report may not include it | Check the report includes this group and the correct applicable milestone |
| Hexavalent chromium in plating | Total chromium results do not differentiate between valence | Request the results of separate determination of hexavalent chromium for plated parts |
| Cadmium in alloys and plating | The limit is tighter so it is easy to exceed even if it is just an impurity | Check the source of alloys, especially brass |
| Lead in soldering and repair materials | Lead-based repair supplies still exist in the production line | Control repair materials and traces of cross-contamination |
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.
