Factory addresses often look consistent until someone compares the records line by line. A supplier questionnaire may list an industrial park, an invoice may use a city office, an audit report may name an older site and a shipping document may identify neither. For an importer preparing a UFLPA mapping file, those gaps are not cosmetic. They make it harder to show where a product or material was made and which entity controlled the work.
An address mismatch does not prove a forced-labor problem. Companies move, use registered offices and work through related facilities. The importer still needs to resolve the mismatch before relying on the file. A reviewer should be able to trace the site named in the supply-chain map to the records that support the current shipment.
Compare the records that describe the site
Gather the supplier registration record, factory license or permit where available, audit report, production agreement, purchase order, invoice and shipping records. Extract the address exactly as written in each document. Do not normalize away differences too early. Building numbers, district names, transliterations and old postal formats can point to either a harmless formatting issue or a real change in location.
Then ask the supplier to explain any difference in writing. The response should identify the registered office, the production site, any subcontractor and the role of each entity. Ask for a date when a site moved or a subcontractor began work. A reply that only says "same company" leaves the importer with no way to connect the explanation to a shipment.
| Record | Address question | Useful support |
|---|---|---|
| Registration record | Where is the legal entity registered? | Official company extract |
| Production evidence | Where was the product made? | Audit, process record or dated factory material |
| Shipment file | Which party supplied this load? | Invoice, packing list and bill of lading |
| Material map | Where did the relevant input pass through? | Supplier declaration and tier records |
Keep the map tied to the product
A company-level file is not enough when different product lines use different plants or subcontractors. Link the address check to the SKU, material, purchase order or production period under review. If a supplier has two factories, record which one made the relevant order and what evidence supports that conclusion. This prevents a clean audit at one facility from being used as a substitute for evidence about another.
Photos and location screenshots can help, but they need context. Save the source page, capture date, site name and the reason the image supports the mapping file. A photograph of a building without a product, date or supplier link is weak evidence. A dated audit page, facility certificate or production record usually carries more weight.
When an address changes shortly before a shipment, pause long enough to understand the change. The importer may decide that a small test shipment can proceed under an existing relationship, but a new facility, new subcontractor or unexplained route change can justify holding a larger order until the map is updated.
Write the unresolved point plainly
Do not fill gaps with a broad assurance that the supplier has been screened. State the missing fact, the person responsible for obtaining it and the commercial limit while it remains open. For example: "The supplier has confirmed a production move, but the current facility permit has not been received. No additional volume will be released until the permit and updated process record are attached."
That kind of note helps the next reviewer and protects the integrity of the file. It separates verified information from the supplier's explanation without treating every discrepancy as proof of wrongdoing.
Preserve the trail for the next review
A supply-chain map should let another reviewer trace a shipment back through the records without relying on a supplier contact's memory. Save the source documents with clear file names, capture dates and the order or product they support. When a location is transliterated differently across records, keep both versions and record how the team matched them.
Review the map again when the supplier adds a site, changes a route, substitutes a material or sends goods from a different exporter. These are practical triggers because they can change the location evidence behind the product. A dated update is more useful than a broad statement that the supplier remains compliant.
When evidence remains incomplete, keep the decision boundary in the shipment file. The importer can explain what it verified, what it requested and what action remains on hold. That is more credible than allowing the uncertainty to disappear into a general supplier scorecard.
Where the importer uses a local-language source, keep the original record with the translation or extraction used in the map. A reviewer can then see the place name as it appeared in the source and understand why the file connects it to the relevant production site.
Working file check. In the context of Factory-address checks in UFLPA mapping files, For small teams, the key is proportionate follow-through. Record what was checked, keep the underlying file where the next owner can find it, and set a review date only where the risk can genuinely change. That approach is more reliable than collecting documents once and assuming they remain valid for every order and market.
