Global buyer checklistBefore quotation or sample

China supplier product specification checklist before you compare or approve.

Give every supplier one identifiable product definition before you compare quotations, ask for a sample or bind a purchase order. Keep the version, materials, dimensions, appearance, packaging, acceptance references and supplier acknowledgement visible in the same record.

SPECIFICATION PATH / 01

Turn a product description into one reviewable baseline before commercial or production decisions start.

A supplier can honestly quote a different material, tolerance, finish, accessory or packing assumption from another supplier. The buyer’s record should distinguish an open product definition from a defined version, then show every exception before the price, sample or order moves forward.

01 / PRODUCT IDENTITY

Name the item, revision and controlling references

Assign a product name, model or SKU, buyer revision, issue date and status. List each drawing, bill of materials, artwork file, colour reference, sample record and earlier change notice by document ID and revision. State which reference controls if two records conflict.

Do not use “same as before”, “latest file” or an unnamed chat attachment as the only definition. Mark the intended use, expected quantity or quantity band, and the exact supplier or factory role receiving the record.

Definition boundary

A product name or SKU may identify a commercial line, but it does not by itself say which material, dimensions, packing, revision or evidence governs this order.

02 / PHYSICAL MAKEUP

State material, components, dimensions and tolerances

Record the material grade or composition description, component list, dimensions, units, tolerances, weight where relevant, assembly or construction constraints and any named substitute policy. Attach the controlled drawing or bill of materials rather than relying on a paraphrase.

Where a field is still undecided, label it as open and name the buyer owner and decision date. A blank field is not evidence that every supplier has made the same assumption.

Comparison boundary

Comparable quotations require comparable assumptions. A precise price against an undefined material or tolerance is not evidence that two offers cover the same product.

03 / VISIBLE AND FUNCTIONAL REFERENCE

Describe appearance, operation and the sample’s role

State the colour, surface finish, texture, artwork, logo placement, accessories and any observable functional behaviour that matters to the buyer. Link photos, approved artwork, mock-ups or sample records to the same revision, and distinguish illustrative references from acceptance references.

A sample can represent a defined version only after the buyer records what it was compared against. Turn a reviewed sample into a traceable approval record →

Evidence boundary

A photo or sample can clarify visible characteristics. It does not independently establish hidden construction, every production unit, destination-market compliance or future-lot performance.

04 / PACKAGING AND LABELS

Make unit, transport packing and labels separate fields

Specify unit packaging, inner packing, outer carton, quantities, dimensions, marks, artwork, label versions and any handling instruction that the supplier is expected to use. Record which item is buyer-provided, supplier-provided or still to be confirmed.

Do not imply that a label layout or transport instruction satisfies any destination requirement. Identify the relevant market and obtain applicable legal, customs, product or labelling advice separately.

Scope boundary

Packaging is part of the ordered product definition when it affects the quote, sample, inspection or shipment. It is not a substitute for a destination-country regulatory determination.

05 / ACCEPTANCE BASIS

Name what will be checked, by whom and against which version

For each required characteristic, identify the referenced standard, buyer requirement, drawing callout, test method, inspection stage or acceptance record that the parties intend to use. Record the owner, timing and unresolved exception. Do not copy a standard number into the record as if it were proof of compliance.

A later quality plan can connect the released product version to production checkpoints and records. Connect a released requirement set to a buyer-owned quality control plan →

Acceptance boundary

Listing an acceptance reference does not validate a test, decide a legal obligation, approve a supplier or guarantee that a product or shipment will pass.

06 / SUPPLIER CONFIRMATION

Ask the supplier to confirm the exact record and exceptions

Send the same controlled revision to each supplier. Ask each one to confirm the version received, identify any exception or substitution, name the production site if relevant and state which fields are priced, sampled or still pending. Preserve the response with the quotation or sample record.

When a buyer selects a supplier, bind the defined version, exceptions and approval limits into the order baseline. Build the purchase-order baseline from the selected product definition →

Any material or documentary change after release needs a visible before-and-after record and buyer-owned decision. Record a supplier change before affected work continues →

Confirmation boundary

A supplier acknowledgement records what the supplier says it has received or can provide. It is not evidence that production, quality, legal compliance or delivery will meet the definition.

METHOD AND LIMITATIONS / 04

This is a controlled-document workflow, not an engineering, legal or supplier decision.

ISO 10007:2017 provides lifecycle guidance for configuration management. We use it only for the general idea that the current product configuration and subsequent changes need to be identifiable. ISO 10005:2018 provides guidance for establishing, reviewing, accepting, applying and revising quality plans; it supports the limited distinction between a defined requirement set and a later control plan.

Currawong Web synthesised the six controls and decision states for evidence organisation. We did not inspect any reader’s product, drawings, supplier, factory, quotation, sample, contract, test, destination rules or shipment. This is general information, not engineering advice, legal advice, a product specification template, regulatory interpretation, supplier approval, contract acceptance or quality guarantee.

COMMON QUESTIONS / 06

Keep the specification record inside its evidence boundary

Is a SKU alone enough to compare supplier quotations?
Not reliably. A SKU may identify a sales line, but a buyer still needs the corresponding revision, physical assumptions, scope and exceptions to know whether quotations refer to the same product.
Is a drawing enough by itself?
It can be a controlling reference when the buyer makes its revision and scope explicit. Materials, packaging, artwork, acceptance evidence and unresolved exceptions may still need their own recorded fields.
Does a supplier statement that the product is “the same as the sample” settle the specification?
No. Record the sample ID and revision, the documents it was compared against and the limits of the decision. The sample, written specification and later production evidence answer different questions.
Should destination-market requirements be copied into this checklist?
Record the applicable source and decision owner where needed, but do not treat this generic guide as a legal or compliance determination. Obtain current, product- and market-specific advice from the relevant authority or qualified adviser.
