A packaging testing report is only truly valuable when it answers the question: Is this packaging pass or fail? It’s worth noting that the ISTA® standard doesn’t answer that question for you. The standard prescribes the test sequence, test levels, and equipment — but the judgment of what constitutes “failure” and what constitutes “pass” rests with the shipper, your business.
This article explains the four points you must settle before the sample leaves the factory, and how to write them into the test requirements so the testing department doesn’t have to figure it out themselves.
1. Why does the standard not pre-define what “pass” means?
The regulatory part of the standard must be common to all types of products, so it can only be descriptive how to test, impossible to describe What is broken?. A 10 mm long scratch on an electronics box and a 10 mm long scratch on an interior wood panel have completely different meanings. At the same level of dented corners, some products are considered defective, some products are still sold normally.
Practical consequences: the testing laboratory can only report the observed condition — “the box has a dented right corner, the tape is partially peeling off, the product has no visible damage to the naked eye”. The report is not pass or fail, because the tester does not know what level is acceptable for your product.
If you don’t finalize the criteria in advance, one of two things will happen: some people think “it’s still acceptable, the product can still be sold”, others think “it’s a mistake if it’s dented” — and both sides fight over emotions. The expensive test results then become meaningless in the very debate it was designed to resolve.
2. The standard requires the shipper to determine two things
In the description of the scope of each process, the ISTA standard states that shipper — and not the testing laboratory — must determine:
- Product damage tolerance level (product damage tolerance) — how much damage is allowed to the product.
- Packaging condition is acceptable at the end of the test (acceptable package condition at the conclusion of the test).
The standard also directs readers to ISTA’s own guidance document on how to select and use processes and projects. In other words, this isn’t a secondary detail — it’s a formal requirement, it’s just stated in one sentence so it’s easy to miss when a business only reads the test sequence.
In fact, for the above two things to work, you need to concretize them into the four points below.
3. Four points businesses must determine for themselves before testing
3.1. What is product damage?
This is a definition, not a numerical threshold. You should distinguish three groups and clearly state which group is considered an error:
- Functional damage: the product no longer functions properly — machine does not start, structure is unstable, welds are cracked.
- Structural damage: cracked, bent, deformed, broken parts — even when the machine is still running.
- Bonded damage: scratches, dents, dirty, chipped paint — the most controversial group, because it depends on the seller and the distribution channel.
For cosmetic damage, state observable threshold instead of speaking in general terms. For example: “scratch on the front surface up to 10 mm, not penetrating the paint layer: not counted as damage”; “Corner dents deeper than 2 mm regardless of location: counted as damage”.
3.2. Acceptable damage tolerance level
There are products that must be achieved not damaged — usually high-end electronic goods, goods with medical requirements. Some products accept slight dents because the packaging is designed to “sacrifice” instead of the product. Both are correct, as long as it is stated clearly up front.
Quantify as much as possible: how many damage points per sample are acceptable, how many samples are allowed to have damage in a repeat series, and where damage is especially serious (for example, the display surface when on the shelf).
3.3. Method for determining product condition after testing
If the criteria are good but the testing method is vague, the results will still be inconsistent. Need to close:
- Check when: after each test step, or just after the end of the entire sequence.
- Who checks?: testing laboratory specialist, business representative present, or both parties check and sign together.
- Where to check?: just observe the outside, or open the packaging, remove the product and test its functions.
- What evidence must be saved?: photos taken of six sides before and after the test, close-up photos of damage details, minutes signed by both parties.
In fact, photos of the original condition are the cheapest and most useful evidence — without them, no one can prove whether the dent came before or after testing.
3.4. What packaging condition is considered acceptable?
This is the most overlooked point. Packaging exists to absorb damage on behalf of the product, so “dented packaging” is normal. It is necessary to clearly state which criteria are important:
- Still keep the product: not so open that the product can fall off or lose accessories.
- There is also identification information: barcodes, batch labels, warnings are still readable.
- There is also the ability to stack If goods must be stored in warehouses or containers.
- Acceptance threshold for each type of damage: torn, dented, damp, glue peeling, dislocated product inside.
If a customer requires packaging to be “as good as new,” it should be bluntly stated that that criterion is nearly impossible to meet with shipping simulation testing — and will cause every test to yield a “fail” result.
4. How to write four criteria into test requirements
The above four points should be submitted at the same time as requesting a quote, not after the results come out. A short form to fill out right away:
- Product and packaging configuration: product name, packaging code, type of insert material.
- Definition of damage: which group is considered an error, observable threshold.
- Tolerance accepted: number of allowed damage points, particularly serious locations.
- Test method: time of inspection, person checking, level of disassembly, evidence that must be saved.
- Packaging condition is acceptable: threshold for each type of loss and remaining required items (label, barcode).
- Confirmer: full name, title, date — so that later no one says “didn’t know this criterion”.
When placing an order, the testing laboratory should be requested Record this set of criteria verbatim in the report and clearly state that the report does not include a pass/fail conclusion. Thus, the report retains its technical value, while the commercial conclusion lies on the business side – exactly as expected.
5. Three common mistakes
- Let the testing laboratory decide “pass” on its own.. Many testing units will write “pass” for convenience, but that conclusion has no basis in your records, and the end customer has the right to not accept it.
- Qualitative criteria (“not damaged”, “packaging is good”). These phrases cannot be verified, so each time you read the results you have to debate them from the beginning.
- Change the criteria after knowing the results. If you see a dented sample and then change the criteria to “accept slight denting”, the entire evidentiary value of that test is lost, and the next test is no longer reliable.
6. Frequently asked questions
Does the testing laboratory make its own pass/fail conclusion?
As the ISTA standard dictates, it is up to the shipper to determine the level of damage tolerance and acceptable packaging condition. The testing laboratory can advise, but the final decision is up to the business.
What if I don’t specify anything?
The report will only describe the current situation. Each party then reads the results in a different way, and the end customer can apply their own criteria — often stricter criteria than you think.
Is this criterion the same for every procedure?
Regarding requirements, it is the same: every procedure requires the shipper to determine. As for the content no similar, because it depends on the product and not on the process code — the criteria for wooden cabinets and the criteria for electronic circuit boards cannot be shared.
Do I have to submit a set of criteria to ISTA?
No. This is an agreement between the business, the testing unit and the end customer. The more clearly the criteria are stated in the test records, the less disputes later.
Can these four criteria replace the content of the standard?
No. They only add parts that the standard intentionally leaves open. Test sequence, test levels and equipment must still comply with the official standard.
7. Conclusion
The ISTA standard does not have a pre-defined definition of “pass” — it is up to the shipper to determine the acceptable product damage tolerance and packaging condition. The most concise way is to concretize those two things into four points (definition of damage, tolerance, inspection method, packaging condition), write in the test request right from the time of scheduling, and ask the testing laboratory to write verbatim in the report.
Doing this takes about an internal meeting. If you don’t do it, every time you get a test result, you’ll spend even more time debating what it means.
