A supplier sample can reveal problems while they are still relatively easy to discuss. It can also create false confidence if you approve it without checking the details that matter in the finished order. Before moving to production, compare the sample with your specification and agree on what the supplier will reproduce.
Confirm what kind of sample you received
Ask whether the sample is an existing stock item, a modified sample, a prototype, or a pre-production sample made with the intended materials and process. These answer different questions. A stock item may help you assess basic size or function, while a customized sample may be needed to check artwork, color, finish, or fit.
Record the sample date, model or revision, materials, options, and any differences from the production version. If the supplier says a feature will change in production, write down exactly what will change and request an updated sample when that feature is important to acceptance.
Check it against written requirements
Use the same specification you plan to attach to the order. Check dimensions, materials, color references, finish, weight, operation, included parts, and any tolerances that matter. For a product with several variants, confirm which variants the sample represents and how the others will be controlled.
Test the sample in the way the product will actually be used, within a sensible test plan for the item. For example, examine the seams and fit of a garment, the closure and leakage of a container, or the connections and operating functions of an electrical product. The test should follow the product's real requirements; one generic checklist cannot cover every category.
Inspect packaging, labels, and included items
A sample may arrive without the packaging or accessories planned for the order. Confirm the package material and dimensions, product labels, barcodes, manuals, inserts, protective materials, and carton markings that will be included. If artwork is not final, identify it as pending rather than treating the sample as approval of the printed version.
Packaging can affect protection, labeling, shipping volume, and the buyer's receiving process. Ask the supplier to confirm which packaging details are included in the quote and whether the final version requires another approval sample.
Keep a clear record of approval and changes
Photograph the sample and keep the approved specification, sample notes, and supplier messages together. Use a simple sign-off record that identifies the exact sample or revision approved, the checks performed, any accepted deviations, and open items. Avoid relying on a message such as “looks good” when the order includes multiple variants or custom details.
If you request a change, ask for the supplier to confirm its impact on price, lead time, materials, and tooling. Review the updated version before approving the change. Make sure older drawings or sample references are clearly marked as superseded so they are not used by mistake.
Ask how production will match the approved sample
Approval establishes a reference, but it does not by itself show how every production unit will be controlled. Ask what checks the supplier performs during production and before shipment, who performs them, and what evidence is available. For products with meaningful variation, agree on measurable acceptance points and the process for handling nonconforming units.
If you plan an independent inspection or product testing, define its scope and timing before production is complete. Agree on who coordinates it, what the inspector will compare against, and what happens if results do not meet the written criteria. The right approach depends on the product, order value, and risks involved.
Resolve sample terms before committing
Confirm the sample charge, courier cost, sample lead time, and whether any fee is credited toward a future order. Ask for bulk pricing and the minimum order quantity as separate terms, and clarify whether sample approval is required before production starts. A supplier may reasonably ask about the expected quantity before investing time in a custom sample; you can share a realistic range without treating that discussion as approval of bulk production.
Do not assume that every supplier can provide a fully customized sample or that the sample will be free. Compare what each supplier is offering and what the sample is meant to prove.
Make a deliberate go or no-go decision
Approve the sample only when it meets the requirements that matter and the remaining deviations are understood. If a critical feature is wrong, ask for a correction or compare another supplier. If an acceptable change raises the cost or changes delivery timing, update the order calculation before deciding.
Once approved, refer to the sample revision and specification in the purchase documents. The sample is a useful checkpoint when it is connected to written requirements, production checks, and a clear agreement about changes.
