Name the decision the sample must support
A concept sample may prove direction but use temporary material. A pre-production sample should reflect intended material, tools, process, finishing, labels, and pack. A shipment sample may confirm a lot. State purpose, quantity, source, production method, differences from final goods, cost, shipping responsibility, customs description, and deadline. Do not ask a buyer to approve “the sample” without defining the approval level.
Make the sample identifiable and representative
Attach supplier, buyer, product code, description, revision, date, batch or job, color or material reference, dimensions, and status. Photograph it consistently and link it to the relevant specification and test report. Protect it in transit and confirm storage or conditioning before evaluation. Hand-selected perfect pieces can mislead if ordinary production cannot reproduce them.
Collect structured feedback
Ask the right reviewers to assess only relevant criteria using agreed lighting, equipment, preparation, use, or test conditions. Record pass, fail, comments, measurements, photographs, deviations, requested corrections, and whether a new sample is required. Consolidate feedback through one owner so the supplier does not receive conflicting instructions from different departments.
Define what approval does and does not mean
Approval should identify the exact sample and covered characteristics. It does not excuse hidden defects, legal noncompliance, unauthorized changes, or failure to meet written requirements. State the validity period, control-sample retention, permitted natural variation, production and shipment inspection, and change-control rule. If the buyer requests a deviation, record its scope and whether it applies once or permanently.
Questions buyers and suppliers often ask
Should samples be free?
There is no universal rule. Agree product, tooling, testing, courier, customs, refund or credit, and ownership costs before work starts.
How many sample rounds are reasonable?
Set an expected number based on complexity and define who pays when requirements change or a sample fails.
Can photos replace a physical sample?
Photos help with screening, but may not prove material, color, fit, taste, performance, scale, or packaging behavior.
