Supplier Control File
The supplier gives one address on the website, another on the business license, and another for inspection or pickup. Turn the issue into a practical buyer-side record.
The supplier gives one address on the website, another on the business license, and another for inspection or pickup. The buyer should anchor the review to the order stage: quotation, deposit, production release, inspection, shipment, or warranty response. The same supplier claim means different things at each stage.
Write the stage before asking for documents. That keeps the review narrow and prevents a broad supplier discussion from replacing the evidence needed for the current decision.
The risk sits on the supplier side: the buyer may inspect the wrong site or trust a trading office as if it controlled production. A supplier may have a normal business reason for the request, but the buyer still needs proof tied to the legal company, order number, product model, person responsible, and date.
When the supplier changes a material, site, process, subcontractor, or test document, record the old and new facts. The change resets the question the original approval answered. Record the result beside the current order. The named scope is China Supplier Factory Address Consistency Check.
Run this review before a factory visit, third-party inspection, or audit booking. That timing matters because practical control falls after money leaves, goods ship, packaging prints, documents reach customs, or customer pressure rises. A late check may only explain the loss after the buyer has already accepted it.
For the production question in this article, match the claim to the product version, production site, batch, test date, and responsible party. A certificate or sample is useful only when the buyer can show which goods it covers. Keep the finding next to the document that triggered the check. The named scope is China Supplier Factory Address Consistency Check.
The review should cover license address, actual factory, warehouse, invoice entity, map location. Ask the supplier to answer with company names, document dates, order references, and the role of the person giving the answer. General statements can stay in the file, but they should not carry the approval by themselves.

The evidence package should include business license, site photos, map pin, inspection booking, supplier explanation. Store those items beside the quotation, invoice, inspection report, payment instruction, and buyer decision note. Use short file names with dates so another person can read the record without replaying the whole conversation.

Open it before a factory visit, third-party inspection, or audit booking. The timing lets the buyer ask for proof before payment, production, shipment, or after-sales pressure narrows the available choices.
It should prove the decision, the supplier-side risk, the evidence received, the evidence rejected, and the approval limit for the next order step.
