A shipment held at the last moment for a document nobody mentioned earlier is one of the most avoidable delays in sourcing. Documents are not difficult; they simply have to be identified before they are needed.
Documents describing what the goods are
Specifications, drawings, material declarations and any statement about composition or finish belong here. They describe the product rather than evidencing a check.
These should already exist from the development stage. If they do not, that is worth noticing — an order proceeding without an agreed written definition of the part is proceeding on memory.
Documents recording what was checked
Inspection records, first-article confirmations and test reports evidence that something was verified, by a method, on a date, on identified samples.
Read the scope and date on each. A report is evidence about the samples it covers, and does not automatically extend to a different variant, a different finish or a later production run.
Documents required for shipment and market access
Commercial documents, packing lists and any documentation your market or customer requires belong here. Which apply depends on your market and your own obligations, determined with your advisers.
These are the ones most likely to hold a shipment, because they often cannot be produced retrospectively at speed.
Ask with a scope, and ask early
A request for “all certificates” cannot be actioned; a request for a named document, covering a named product scope, for a named market can. The difference is usually several days of clarification.
Raise the requirement at enquiry stage. Some documents depend on testing that has to be planned into the production schedule rather than added at the end.
Keeping documents matched to the goods
Documents should reference the part number, version, order and batch they relate to. A test report that cannot be tied to a specific delivery has limited value in an audit or a dispute.
Agree that documents carry these references, and file them against the delivery rather than in a general folder.
What to establish at enquiry stage
Which documents you need, the scope of each, who issues them, when they are produced relative to shipment, what references they must carry, how long they remain valid, and what triggers a refresh.
This guide names no specific certificates and makes no statement about what any supplier holds. Determine your requirements with your own advisers, then state them precisely — that is what makes them straightforward to satisfy.
Documentation divides into descriptions, records of checks and shipment requirements. Identify what you need at enquiry stage with a named scope, ensure each document references the part, order and batch, and file them against the delivery.
