Product samples from China: what to approve before bulk production

GURI Journal · Published 31 October 2026
A sample is useful when you know what it represents. A factory may send an existing item to demonstrate workmanship, a prototype to explore a shape or a pre-production version made with the intended materials. These can all support a purchase decision, but they do not provide the same evidence.
GURI recommends defining the decision before ordering the sample. Identify the properties you need to assess, the differences you can temporarily accept and the questions that require another test. Approval then becomes a specific instruction rather than a vague expression of satisfaction.
Give each sample a purpose
State whether you are assessing dimensions, appearance, compatibility, function, material or packing. Describe the conditions in which the product will be used. If it connects to another item, provide the relevant interface information or a suitable reference part. An isolated measurement may not establish compatibility of the assembled product.
Distinguish an existing catalogue item from a custom version. A stock sample can help assess a supplier's execution, but it does not demonstrate changes that have not yet been made. Conversely, full custom development may be unnecessary when the immediate decision concerns a standard material or finish.
Alibaba's buyer guidance treats requesting a product sample as a separate step before a wholesale order. That is a useful distinction, not a universal promise about sample prices, delivery times or the quality of every supplier offering samples.
List temporary materials and processes
Ask the supplier to identify anything that differs from the intended production version. This may include a colour, fastener, coating, label or manufacturing method. A temporary part does not make the entire sample worthless; it limits which conclusions can reasonably be drawn from it.
Check availability of the components you like. A sample made with a leftover premium component may be difficult to reproduce at the quoted price or order quantity. Resolve the production alternative before approving the run, rather than discovering the difference in the finished shipment.
Hand finishing also needs clarification. It can be appropriate for developing a shape, but it may not reflect the standard production process. The final reference should represent the agreed commercial version, including any operations that are necessary to achieve the approved result.
Agree development costs and revisions
Separate the sample itself from drawings, patterns, tooling, materials and delivery. Clarify the number and scope of included revisions. A substantial design change may justify extra work, but both parties should understand what changed and why a new charge is proposed.
If sample fees are credited against production, record the conditions. Specify the relevant product, quantity and timing rather than treating a possible credit as an immediate discount. Also agree access to development files and tooling where relevant; payment alone does not explain storage, ownership or future use.
Plan enough time to review the sample and communicate changes. A schedule that assumes approval on the delivery day leaves no practical room to discover a problem. The review period is part of development, not an unexpected delay caused by the buyer doing the agreed checks.
Identify and assess what arrives
Record the supplier, sample number, version and condition on arrival. Keep the packaging until you have checked for damage and completeness. If several candidates send similar products, label them before comparing them so that observations remain connected to the correct supplier and specification.
Use a consistent measurement method. State the product condition, measurement points and relevant reference equipment. A flexible or adjustable item can give different readings depending on how it is positioned. Agreeing the method helps distinguish a real deviation from a difference in interpretation.
Turn subjective concerns into actionable observations. Instead of simply saying an item is difficult to open, describe the action, where it catches and what the user is expected to do. The explanation gives the manufacturer something to investigate without pretending every aspect of usability is reducible to one number.
Separate practical assessment from formal testing
Trying the intended function can reveal a construction problem. It does not automatically establish durability, chemical properties or compliance with all applicable requirements. Those questions need suitable methods, criteria and representative samples, selected for the product and destination market.
Avoid improvised loads or arbitrary cycle counts presented as proof of long-term performance. If a test is destructive, decide which observations must happen first and whether another specimen is needed as a retained reference. Document the tested sample's identity so results remain connected to the correct version.
Check claims against the evidence. A property of one material does not necessarily describe the assembled product. A product description should not acquire a stronger performance promise merely because the development sample looked convincing during an informal demonstration.
Approve corrections with their consequences
Give each correction an identifier, location and expected outcome. Mark photographs and specify measurement points where useful. If several alternatives are under discussion, make the final choice explicit. Production should not have to decide which suggestion in a long message thread is the approved instruction.
Review connected features after a change. A larger opening can affect a neighbouring seam; a different insert can alter usable space; revised packing can change shipping dimensions. Confirming that the original issue disappeared is only part of checking the revised product.
The final approval should identify the sample, date and scope, with unresolved matters listed separately. Keep the reference and specification available to production and inspection. This makes the sample a practical basis for the bulk order, with clear limits, rather than a reassuring object disconnected from the goods that will actually be made.
