Steel Export Documents Checklist: 10 Must-Have Papers
When a steel shipment leaves the mill, the goods are only half the transaction — the documents are the other half. Missing, inconsistent, or sloppy paperwork delays customs clearance, blocks letter-of-credit payment, and can turn a good cargo into a demurrage bill. This checklist covers the ten documents every carbon steel export shipment should carry, what each one proves, and the details buyers must verify before the container is sealed.
1. Commercial Invoice
The commercial invoice is the financial spine of the shipment: it states seller and buyer, contract or PI number, full goods description, HS code, quantity, unit price, total value, currency, and Incoterms 2020 rule with the named place. Customs authorities in nearly every country value the cargo against this document, so description and value must match the packing list and bill of lading exactly. For LC payments, the invoice must comply with UCP 600 — spelling of quantities, unit, and terms counts.
2. Packing List
The packing list itemizes what is physically in the shipment: bundles, crates, pieces, weights per package, gross and net weight, marks and numbers, and container or vessel allocation. Steel shipments are usually invoiced on theoretical weight per the dimension standard, so the packing list should show both theoretical and actual (weighed) figures where applicable — the mismatch between the two is the most common cause of weight claims on long products.
3. Mill Test Certificate (MTC)
The MTC — normally EN 10204 type 3.1 — is the quality passport: heat chemistry, mechanical test results, heat treatment condition, and traceability to heat numbers on the goods. Buyers should verify three things: the standard and grade match the purchase order; heat numbers on the certificate match the stencil marks on the material; and any agreed extras (Charpy, hardness, UT, Z-test) appear with actual values. For critical projects, a 3.2 certificate issued by a third party (SGS, BV, TUV, TPI of your choice) adds independent verification.
4. Bill of Lading (B/L) — or Equivalent Transport Document
The ocean bill of lading is simultaneously a receipt, a contract of carriage, and — in negotiable form — the document of title. Check: correct shipper and consignee (or “to order” for LC), clean notation (no damage remarks), shipped-on-board date, ports of loading and discharge matching the LC, and the number of originals issued. For containerized steel, a multimodal B/L may be issued; for bulk vessels, the master’s B/L plus mate’s receipt. Air waybills and CMR/road consignment notes replace it for air and land shipments.
5. Certificate of Origin (CO)
The CO declares where the goods were manufactured, issued by the chamber of commerce (CCPIT in China) or, for preferential trade, by customs under FTA rules. Many importing countries require it for customs valuation, and under free-trade agreements (e.g., ASEAN–China, RCEP) a preferential CO can cut the import duty to zero. Confirm the correct form type with your customs broker before shipment — a wrong-form CO cannot always be fixed after departure.
6. HS Code Classification and Compliance
Every steel product line on the invoice needs a valid HS code — Chapter 72 covers iron and steel; the digits encode product form (flat, bar, tube), treatment, and composition. Wrong classification means wrong duty, possible penalties, and clearance delays. Compare the HS code on the invoice with your country’s tariff schedule (and any anti-dumping duty listings for the specific product and origin) before the contract is signed, not when the goods arrive.
7. Insurance Certificate (CIF/CFR Terms)
Under CIF and CIP the seller insures; the insurance certificate must show coverage per the contract — Institute Cargo Clauses (A) preferred for steel, 110% of invoice value, claims payable in the destination currency. Steel’s main transit risks are physical damage (bundle breakage, water staining) and theft; buyers on FOB or CFR terms arrange their own cover and should not assume the seller’s marine policy extends to their leg.
8. Third-Party Inspection Certificate
When the contract specifies TPI, the inspection certificate (SGS, BV, Intertek, or a nominated agency) documents what was verified at the mill: quantity and marking check, dimensional sampling, visual condition, MTC review, and photos. The certificate should reference the PO and report number. For government and project buyers, this document is often a payment milestone — schedule the inspection before vessel departure, not after, and include re-inspection terms for failures.
9. Fumigation / ISPM 15 Certificate (Wood Packaging)
Any wooden crates, pallets, or dunnage must comply with ISPM 15: heat-treated (HT) or fumigated (MB is largely phased out) and stamped with the IPPC mark. Australia, New Zealand, and several other markets enforce this strictly and will re-export or treat the cargo at the importer’s cost. Use steel strapping and timber from certified suppliers, and keep the treatment certificate with the document set.
10. Additional Certificates Often Required
Document Consistency: The Golden Rule
Customs officers and LC banks check documents against each other. The five fields that must match across invoice, packing list, B/L, CO, and MTC are: consignee name, goods description, quantity, weight, and marks/numbers. A single mismatch — “steel plates” on one document, “steel sheets” on another — can trigger an LC discrepancy (typically USD 50–150 per discrepancy plus delay) or a customs query. Ask your supplier for a document draft set (blurred or unsealed) 3–5 days before vessel departure to review while corrections are still possible.

FAQ
What is the difference between a 3.1 and 3.2 MTC?
A 3.1 certificate is issued by the manufacturer’s own authorized inspection representative; a 3.2 is validated by both the manufacturer and an independent third party. Critical and project steel usually demands 3.2.
Can a bill of lading be corrected after issue?
Yes, via a B/L amendment at the carrier’s office, usually with a fee and only before the original set is surrendered. Some corrections require returning all originals. Better to verify the draft B/L before sailing.
Which document is checked first at customs?
Typically the bill of lading and commercial invoice drive the manifest match, then the CO and HS classification determine duty. The MTC is usually checked later by the importer’s quality team, though some authorities request it for specific steel codes.
Do I need insurance if I buy FOB?
Yes — under FOB the buyer bears risk from the moment goods pass the ship’s rail (or on-board under Incoterms 2020), so the buyer must arrange marine cargo insurance from loading port.
