Export documents and standard cross-reference
Exporting steel plate is not complicated, but the paper chain is long: mill certificates, class documents, fumigation, certificates of origin — one broken link strands cargo at the destination port. Here is the timeline of a typical order with the document list and the usual snag points.
Before production: settle the standard
Three questions first: which standard governs (GB, EN, ASTM/ASME, JIS)? which certificates (EN10204 3.1/3.2, class society, third-party report)? what does the destination market require? Order to the target standard directly — shipping Chinese-standard plate with an English translation as an "equivalent" plants a dispute at customs or at the owner's inspection.
The document chain, in order
| Stage | Document | Issuer | Watch for |
|---|---|---|---|
| Order | technical clauses | both parties | standard, condition, UT, impact temperature — every line |
| Production | mill certificate EN10204 3.1/3.2 | mill / third party | heat numbers, chemistry, mechanicals match the goods |
| Inspection | third-party report (SGS/BV) | third party | pre-shipment, witnessed sampling |
| Class | class society certificate (if required) | survey body | the owner's nominated society |
| Packing | fumigation certificate (IPPC) | packer | ISPM marks on all timber |
| Customs | certificate of origin | chamber of commerce | form per destination tariff rules |
| Payment | packing list, invoice, B/L | exporter | piece count and weights match reality |
Packing and loading
Loose plate bundles with steel strapping and corner guards; cut parts travel in containers on timber skids with separators. Flat-rack and break-bulk pieces get lateral securing to a photographed plan sent ahead for approval. Every package carries a shipping mark: order number, description, size, pieces, gross/net. Confirm destination lifting capacity and inland haulage for oversize before the vessel is fixed.
The usual snag points
- Certificate data vs shipping marks vs packing list — reconcile all three before loading
- Timber without IPPC marks — catch it at the packing stage
- Impact test temperature not per design — write the test temperature into the order
- Wrong class certificate format — confirm the society and format with the owner early
