How to Set a China Pre-Production Sample Handover Checklist

A pre-production sample should not arrive as an isolated object. Before the supplier ships it, agree the exact unit, configuration, documents, and decision needed from the review. The buyer's coordinator should be able to answer one practical question immediately: does this submission represent the version the factory is allowed to produce?

If the answer is unclear, record the gap and keep production authorization open. This is a recommended buyer-side workflow, not an official approval standard or a substitute for product-specific technical, regulatory, or contractual review.

Match the sample to the approved specification

Give the sample a unique identifier before dispatch. The supplier's cover sheet should state the model or SKU, variant, quantity, production stage, and date sent. It should also identify the specification, drawing, bill of materials, artwork, and revision that the sample represents. If two variants are enclosed, label each one separately rather than treating the parcel as a single reference unit.

The receiving coordinator should compare those identifiers with the buyer's controlled files. Check dimensions, materials, colors, components, firmware or software version where relevant, and any agreed tolerances. A photograph can help identify appearance, but it cannot replace a controlled specification or configuration record.

When a sample uses a temporary component, hand adjustment, substitute material, or unfinished tooling, ask the supplier to disclose it. The technical reviewer—not the person coordinating the shipment—should decide whether the difference affects the evidence needed before production.

Build a dispatch register that exposes missing items

List every physical item in the handover: product unit, accessory, spare part, retail box, insert, label proof, material swatch, or reference sample. Record quantity, identifier, purpose, and condition. Mark each item as enclosed, promised separately, or not applicable. This prevents a missing document or component from being mistaken for a courier problem.

Create a parallel digital index. Name each file, revision, format, and owner, and identify where the reviewer should find it. Include the specification, drawings, artwork, assembly instructions, photographs, inspection records, and test reports that are within scope. If a file changes after dispatch, require the supplier to state what changed and which earlier revision it replaces.

Define the review scope before the parcel leaves the factory. For example, a submission may cover assembly fit and appearance but exclude final packaging performance. Write exclusions on the cover sheet. Otherwise, a proof sent for text review may later be treated as approval of the complete pack.

Separate packaging, labels, and shipment evidence

Packaging needs its own comparison record. List the intended contents of each retail or bulk pack, the relevant artwork revision, and the evidence type: physical sample, photograph, dieline, or digital proof. Where protection or internal positioning matters, request photographs that show the product inside the pack, not only the closed exterior.

Assign label review to a named owner. That person should compare identifiers, wording, placement, language versions, and artwork revisions against the buyer's controlled files. If barcode scanning or another performance check is required, specify the method, equipment or conditions, result, and record location. Questions about destination-market warnings or mandatory wording should go to the responsible compliance specialist.

Do not confuse the courier parcel with the planned shipment pack. Record carton construction, marks, dimensions, and other bulk-pack details separately when they become available. Before freight booking, the responsible person can use the packing-list review resource as a later document-control reference. It does not resolve an unanswered sample-stage packaging question.

Review test evidence for applicability, not appearance

An evidence index should identify the check, tested unit or configuration, method, conditions, acceptance criterion, result, date, performer, and file reference. Keep factory observations, buyer assessments, and laboratory reports in separate categories. A cover email saying “passed” is not enough for a reviewer to determine what was actually checked.

Compare the report's identifiers with the submitted sample. If the report covers another model, component arrangement, material, or revision, record an applicability question and send it to the competent technical reviewer. Do not close that question because the report has a familiar format or the product photograph looks similar.

Also list checks that have not yet been performed. Name the person who will arrange them, the sample or configuration to be used, and the evidence required for closure. Agree whether the reference unit must remain intact or may be used for destructive evaluation. The handover workflow records the decision; it does not determine which tests a product or market requires.

Assign ownership for exceptions and release

Use a responsibility record with at least four functions: supplier submission owner, buyer review coordinator, specialist reviewers, and production authorizer. One person may perform more than one function, but the assignments should be explicit. Set a review date by agreement and state what happens if required evidence is late. Silence should not be interpreted as permission to start production.

For every open item, record the reference, discrepancy or question, proposed action, owner, target date, and evidence needed for closure. Keep an undefined requirement separate from a failed requirement. If the specification says nothing about opening force, that is a buyer clarification. If it sets a limit and the measured result exceeds it, that is a discrepancy requiring corrective action.

Separate a request to change the specification from a request to meet it. If the buyer accepts a limited departure, document the affected configuration, quantity, duration, and authorizer. The supplier should receive one consolidated disposition rather than competing instructions from several reviewers.

Turn the decision into a factory instruction

Hypothetical example: A buyer receives a folding laptop stand with two interchangeable hinge inserts. The supplier's documents describe the stand but do not identify which insert is intended for production. The coordinator records the ambiguity, asks the supplier to identify the selected configuration, and requests the agreed stability evidence for that configuration. Production authorization remains open while the answer is missing.

Once the technical reviewer accepts the response, the authorized buyer issues a dated decision that names the selected insert, sample identifier, evidence record, specification revision, and permitted next activity. The supplier's production contact acknowledges the same references and identifies where they will appear in work instructions and subsequent inspection records.

Close the handover only when the parties can state what was accepted, what remains restricted, and what may happen next. Retain the reference unit and decision record under an agreed document-control arrangement. If the supplier later proposes a different insert, material, artwork revision, or packaging configuration, return the change to review rather than allowing the earlier decision to cover it automatically.

For a broader sourcing question or an unresolved coordination task, the sourcing inquiry page is an available contact route. Provide the sample identifier, missing evidence, responsible owner, and requested deliverable instead of asking for an undefined approval.
