How to Read a Jewelry Factory's QC Report (Without Taking It on Trust) - FSC CRAFT

"There is a full quality check before shipment" is a sentence every supplier writes. The report is where it either becomes evidence or stays a sentence.

Most buyers cannot read a QC report because nobody taught them the vocabulary. This page does.

What a QC report is supposed to contain

A report tied to a specific order should be traceable to that order. If it is not, it is a marketing document:

• Order and batch identification — the order reference, the SKU, the production date range.
• Quantity inspected and quantity produced.
• Standard used — the inspection standard and the defect classification.
• Sample level — how many units were inspected, and against what rule.
• Defect classes and counts — usually split into critical, major and minor.
• Result — pass, conditional pass, or reject, with the action taken.
• Inspector name and date, plus the standard they were working to.
• Photos, ideally of the defects found, not only of the finished goods.

A report with none of these is a summary, not a record.

Defect classes are the useful part

Almost every inspection standard sorts defects into three groups, and the counts tell you the real quality story:

• Critical — a defect that makes the product unsafe or unusable, or that a customer would call it immediately. A clasp that fails. A sharp edge. A box that will not close.
• Major — a defect that would annoy a customer but not stop the sale. An uneven interior lining. A visible plating flaw at the front.
• Minor — a cosmetic deviation that most customers would not notice at all.

A run with zero critical defects and a handful of minors is a normal, healthy result. A run with zero defects of any kind is either a very small sample or an inspection that was not done properly. Learn to be suspicious of the flawless report — it usually means the inspection was cursory, not that the batch was perfect.

AQL: what "sampled" actually means

Sampling is defined by an AQL (acceptable quality limit) standard, most commonly ANSI/ASQ Z1.4 / ISO 2859-1 for a normal inspection level. AQL sets how many units are inspected and how many defects are tolerated before the batch fails.

• A small AQL means you require a high standard.
• A zero-tolerance critical defect rule means any critical defect fails the batch.
• AQL applies to the batch, not to the individual unit. It does not mean defects are acceptable to your customer — it means the batch meets your agreed level.

If a supplier cannot tell you the AQL or sample level they inspected to, ask. Suppliers who inspect to a stated standard have nothing to hide.

The questions worth asking

• Which standard did you inspect to, and at what AQL?
• How many units were inspected, out of how many produced?
• Were the defects photographed? Reports with only finished-goods photos have not shown you the problems.
• What was reworked, and how was the rework verified?
• Is the report tied to my batch, or is it a reference report for the design?
• Can I inspect, or appoint a third party, before shipment?

A supplier who answers all six without hesitation is telling you the truth. A supplier who answers "everything is fine, we check everything" has not told you anything.

Plating and dimensional results

Two results on a jewelry report matter more than the rest:

• Dimensional check against the approved sample — measured, not eyeballed. This is how you catch the interior-depth problem before it ships.
• Plating thickness — measured by XRF or cross-section microscopy, and stated as a value rather than "complies".

These are the checks where compliance documentation and quality control meet, and they are the ones most often missing from a light-touch report.

What to do with a report that looks wrong

• Ask for the sample level and defect counts before you conclude anything. A reject with a clear rework record is a better outcome than a silent pass.
• Hold the balance. The pre-shipment balance is your leverage and it is the normal place for it.
• Ask for a third-party inspection. If the numbers do not convince you, an independent inspection does.
• Document the reference. Keep the approved sample, the spec sheet, and the report. That is the set you will need in six months.

FAQ

Do you provide QC reports?

Yes, for each order. They are tied to the batch, and we can tell you the standard and sample level we inspected to.

Can I inspect before shipment?

Yes. You can inspect yourself, appoint a third party, or ask us to arrange one. We will not stop you from verifying your own order.

What if I find a defect myself?

Tell us before shipment. It is far cheaper to fix in production than to negotiate from your own warehouse.

Is a report with defects worse than one with none?

Often better. A report with honest counts and a clear rework record tells you the system works. A flawless one may mean nothing was measured.

Do you photograph defects?

We can, and we do when the defect is one worth showing. Reports that only show finished goods have not shown you anything.

Ask for your QC report at RFQ stage — not after production. We will tell you what we inspect to and how. Contact FSC CRAFT.
