Evidence for a Quality Claim: What You Need Before You Ask (2026)

Quick answer. A quality claim is settled by evidence rather than by argument, and the first document in that evidence is the specification rather than the photograph. What makes a claim succeed is a comparison — the written specification, the sealed sample and the records from the run, held before the shipment arrives rather than assembled afterwards.

1. The four pieces of evidence

  • The written specification. Fibre, blend ratio, weight, measurements with tolerances and construction detail. Without it there is no standard to depart from.
  • The sealed approved sample. Held by both sides, since it is what the delivery is measured against.
  • The inspection records. Produced during the run, which describe the process rather than only the goods.
  • Evidence from arrival. Photographs with the batch reference visible, counts, and where relevant a third-party re-inspection.

2. Why claims fail

  • No comparison basis. The most common reason, and it is a specification problem rather than a quality one.
  • Verbal specification. Which turns the claim into a discussion about recollection.
  • Evidence gathered too late. Goods repacked, distributed or disposed of before they were documented.
  • Photographs without the batch reference. Which cannot be tied to the shipment being claimed about.
  • Claiming a delivery against a sample nobody sealed. Which leaves the two sides comparing different garments.
  • A total figure without a defect type. Which cannot be traced to a stage, so the remedy cannot be aimed.

3. What to do at arrival

  • Inspect against the reference. Measurements at the points of measure, against the approved tolerances.
  • Photograph with the reference visible. The batch number, the carton mark and the carton in context, not only the defect.
  • Count and classify. How many units, of which defect type, and at which severity.
  • Keep the packaging. The pack and the carton marks are part of the evidence.
  • Do it in the first days. Not because of a rule, but because that is when the goods are still exactly as they arrived.

4. How a claim is raised

  • Notify in writing within the stated period. Which is why the period belongs in the agreement rather than in a convention.
  • Attach the evidence. Specification, reference sample, records and the arrival documentation, as one set.
  • Name the defect type. Rather than describing a general dissatisfaction, since the type is what the remedy attaches to.
  • State what is asked for. Replacement, credit or rework, with the schedule effect of each.
  • Ask for the corrective action. Since a claim that ends in a credit note leaves the stage unchanged.

5. The comparison that decides it

  • Delivered against specified. Measurements and construction, item by item.
  • Delivered against sealed. The reference both sides hold.
  • Delivered against the records. Whether the run’s own checks would have caught it, and whether they did.
  • A verifiable claim needs all three. Which is why the evidence is assembled before the conversation rather than during it.

6. Common errors

  • Leading with the photograph. Which shows a problem without establishing the standard it departed from.
  • Waiting for a pattern to emerge. The evidence is strongest in the first days after arrival.
  • Claiming on a description. Which is where a verbal specification becomes expensive.
  • Accepting a credit without a process change. Which resolves the cost and repeats the cause.
  • Not stating the defect type. Which leaves the remedy unattached to anything specific.
  • Filing the evidence separately from the order. Which is how the reference cannot be found when it is needed.

7. How to compare two suppliers on this

  • Both with a written specification. Since it is the first document a claim depends on.
  • Both with a sealed sample held. By the supplier as well as the buyer.
  • Both with records produced during the run. Rather than a report written for the shipment.
  • Both with a stated claim period. Since the notice period is what makes a claim timely.
  • Both with a stated corrective-action expectation. Which is what distinguishes a supplier who fixes from one who credits.

Buyer Questions

MOQ, lead times, certification and trading terms

Four pieces: the written specification, the sealed approved sample, the inspection records from the run, and evidence from arrival — photographs with the batch reference, counts, and a third-party re-inspection where one was used. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Most often because there is no comparison basis. Without a written specification and a sealed sample there is nothing to measure the delivery against, and the claim becomes a discussion about recollection rather than about a standard. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

In the first days after arrival, while the goods are exactly as received. Once they have been repacked, distributed or disposed of, the strongest evidence is no longer available. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Because it has to be tied to the shipment being claimed about. A photograph of a defect without the batch reference cannot show which carton or which run it came from. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

A credit resolves the cost but leaves the stage that produced the defect unchanged. Asking for the corrective action alongside the remedy is what stops the same claim returning on the next order. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

In the agreement, since the notice period is what makes a claim timely. A convention that nobody wrote down is the kind of thing that is discovered when it is too late to use it. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
