Pick the sample by the risk you are trying to retire, not by the label a supplier puts on it. A stock sample answers "does this existing form factor work for my shelf?" A color sample answers "can this factory hit my approved color and decoration?" A prototype answers "is this concept buildable at all?" None of the three proves the other two.
That distinction matters because the failure mode is almost never "we ordered the wrong sample type." It is a buyer approving a generic unit and then discovering the production lot used a different resin, a shifted registration, or a certificate that covers a different model. Match the sample to the decision stage, then bind the approved unit to the purchase order by revision number, lot, and file.
Which files should exist before a purchase order?
| Approved sample record (sample ID, photos, approver, date, revision) | Proves which physical unit both sides agreed on, and when. Does not prove the factory can repeat it. Ask for the sample ID to be written into the PO if it is missing. |
|---|---|
| Material and color standard (resin grade, Pantone/CMYK, finish) | Proves the intended material and color target. Does not prove the production lot used them. Ask for a physical swatch and a bill-of-materials cross-check if only a digital proof exists. |
| Test / compliance report (type-test or golden-sample report) | Proves a tested sample of a stated model met a stated standard. Does not automatically cover a later production lot. Ask for report SKU, material, color, and production date/cohort to be matched to your PO. |
| Packing and labeling spec (carton, barcode, warnings, inserts) | Proves the agreed retail packaging. Does not prove carton fit or drop resilience. Ask for a packed sample or a drops/compression test if the item ships fragile. |
| CE declaration (where applicable) | Proves the manufacturer's own conformity declaration. Does not prove approval by an EU authority, and does not identify product origin. According to the European Commission, CE marking is the manufacturer's declaration and is not an EU authority's approval — so ask which exact file covers which test if a catalog shows a CE string. |
| Battery-law and child-access review (button/coin cell items) | Proves the battery and ingestion-hazard questions were reviewed separately. Does not let one review substitute for the other. Ask for both if your item has a coin cell. |
Why the revision card is the file that arrives late
The revision card. Buyers chase the sample, the price, and the color, and then discover that the unit in hand and the unit on the line are different builds. At a Canton Fair a booth sample is often a hero unit — hand-finished, specially lit, and not the production standard. Fair lighting lies; the revision card does not.
Every sample that leaves a factory or a booth should carry a tool number and a revision, and your PO should reference that revision. When a supplier changes a mold, a resin, or a decoration method after you approved a unit, that is a new revision and it needs a new sign-off. This is also the cheapest place to catch a substitution: a supplier who cannot name the tool and revision for your order probably has not separated your build from the last buyer's.
The same logic holds across a catalog. A color-matching board game in ABS and a 1:16 drift car in plastic may come from the same factory floor, but they carry different tool numbers, different material specs, and different test files. Approving one tells you nothing about the other. Write the revision, the material, and the applicable file onto the PO, and keep the signed unit sealed as the production benchmark — a sealed golden sample with approved material, color, decoration, dimensions and photos is a practical QC reference, though it does not replace required market testing.
FAQ
If a supplier sends a free stock sample, is that better than a paid one?
No. Free versus paid does not indicate supplier quality. What matters is what the sample represents and what the fee covers — product, customization, tooling, or shipping. Clarify before ordering whether the sample fee can be credited against a production order.
Does an approved sample guarantee the bulk order will match?
No. Sample approval is not a substitute for production quality control. A good sample does not prove every production unit will be identical, so larger orders may still need in-production monitoring or pre-shipment inspection.
A catalog listing shows a CE string. Can I describe the toy as EU-approved?
No. According to the European Commission, the manufacturer's CE declaration is distinct from approval by an EU authority, and CE marking does not identify a product's origin. Check the exact product file and applicable requirements instead of treating a CE image as authority approval.
My item uses a button or coin cell. Is one document enough?
No. A toy with a button or coin cell needs both battery-law review and child-access/ingestion hazard review; one does not replace the other. Confirm which file covers which test, and that it names your model.
The test report is for the right model but an older date. Does it cover my shipment?
Not automatically. A type-test or golden-sample report does not automatically cover a later production lot. Match the report's SKU, materials, colors, and production date or cohort to your purchase order before relying on it.
What should I ask the factory if no revision card exists?
Ask for the tool number, the current revision, and the material and color standard in writing, then have the approved sample ID referenced on the PO. If the supplier cannot name the tool and revision, treat the sample as unverified.

Check the sample before you commit
Before you contact a supplier or release a PO, confirm three things in writing: which sample type fits your decision, the tool and revision number behind the unit, and which file covers which model and lot. If you are evaluating a catalog item, start from the record and reconfirm the sample, current quote, age evidence, and destination documents — for example, the Cute Plastic Seven-Color Flower Shaped Electric Bubble Machine for Kids Outdoor Play Bubble Blower & Spit Wand, where the catalog snapshot establishes a catalog record only, not certification, infant suitability, licensing, or stock.
