A China sample revision process works when every difference becomes a traceable instruction. Identify the sample and requirement version, describe the observed difference against a named reference, state the requested correction and priority, ask the supplier to confirm its response, and define what evidence the next round must provide. A revised sample can show whether a specific change was addressed. It does not guarantee mass-production quality, compliance, price, delivery or supplier capability.<\/p>\n
The goal is not to write a longer complaint. It is to make the next decision easier. When feedback is scattered across messages, a supplier may follow an old request, miss a critical point or make an unapproved substitution. A single revision record gives both parties one current reference and shows which issues remain open.<\/p>\n
Review the current sample against the current specification, not against memory. Use one revision record to link each issue to the sample version, requirement reference, observed difference, requested correction, priority, supplier response and evidence needed for closure. Separate must-change items from suggestions. Ask the supplier to confirm its understanding before it prepares the next version. Close an issue only after the buyer has reviewed the agreed evidence and updated the product record where necessary.<\/p>\n
Begin by identifying the sample you are reviewing. Record the supplier, product code, sample version, date received and the versions of the specification, drawing, packaging artwork or reference files used for comparison. A revision record is only useful when everyone knows which version it describes.<\/p>\n
Then create one numbered list of issues for the current round. Do not send separate correction requests through email, chat and a shared document without a final consolidated list. The supplier needs one version of the instructions, and the buyer needs one place to see whether the supplier accepted, questioned or completed each item.<\/p>\n
Prestige Sourcing’s guide to product samples from China<\/a> recommends keeping a revision record with the sample version, requested changes, supplier response, approval status and accepted deviations. That record keeps earlier samples from being treated as current production references after the buyer has moved to a later version.<\/p>\n The revision record should also state the sample’s purpose. A development sample may be intended to test a product feature. A later production-intent sample may be intended to review the materials, components or packaging the supplier says it will use in bulk. The same correction note can have a different meaning depending on which sample the buyer is reviewing.<\/p>\n Describe a difference by comparison. State the relevant product area, the reference requirement, what you observed and what must change. A note such as “improve quality” is difficult to implement. A note that says “use the approved matte finish from specification version four on the front panel” gives the supplier a clearer instruction.<\/p>\n Use photos, drawings or files where they clarify the point. Mark the location of an issue, but add a written description and reference number. A photograph can show where a mark appears, while the written record can state whether the issue affects a product requirement, what correction is requested and which version should be used in the next round.<\/p>\n Maple Sourcing’s sample-order management guide<\/a> advises replacing broad judgments with specific comparisons and making a clear distinction between essential and optional changes. That is useful because a supplier cannot reliably prioritise an issue if the buyer has not said whether it blocks approval.<\/p>\n Do not invent a tolerance after the sample arrives simply to explain an outcome you did not expect. If a measurement, colour, material or finish needs an acceptance range or method, agree the requirement and update the current product specification sheet<\/a>. The next sample should be reviewed against the updated record.<\/p>\n Mark each feedback item according to the decision needed. A must-change item means the buyer will not approve the relevant sample scope unless the stated condition is corrected. An open question means the buyer still needs information, a proposed alternative or specialist input before deciding. A preference may be useful feedback, but it should not be presented as a mandatory production requirement unless the buyer has made that decision.<\/p>\n This distinction prevents two common problems. First, a supplier may spend time improving a low-priority detail while missing a product issue that blocks the next sample decision. Second, a buyer may treat an unresolved question as if it had been agreed merely because it appeared in a feedback message.<\/p>\nWrite feedback the supplier can act on<\/h2>\n
