Carbon Steel Import Documents Checklist: BL, MTC & CO

Importing carbon steel is not just about price and quality. One missing or incorrect document can hold a container at the port for days, trigger a customs inspection, or cause the buyer to reject the shipment. Whether you are importing hot-rolled coils from China, seamless pipe from India or cold-drawn bars from Turkey, the paperwork must be complete, consistent and compliant with the destination country’s regulations.

This checklist covers the documents normally required for a carbon steel import transaction. Use it to verify your supplier’s paperwork before shipment and to prepare your customs declaration on arrival.

1. Commercial Invoice

The commercial invoice is the foundation of the customs declaration. It must match the packing list, bill of lading and the actual goods in every detail. Customs officers compare invoice values to market benchmarks, so inconsistencies can trigger valuation audits or anti-dumping reviews.

• Exporter and importer full names, addresses and tax IDs
• Invoice number, date and purchase order reference
• Description of goods: grade, standard, dimensions, finish, quantity and unit price
• HS code for each product line
• Total value, currency and Incoterms
• Country of origin and signature of exporter

2. Packing List

The packing list describes how the goods are physically packed. It helps customs inspectors locate specific bundles, coils or pipes without unloading the entire container. It also supports weight reconciliation between the bill of lading and the invoice.

• Package number, type and dimensions
• Net weight and gross weight per package
• Total net and gross weight
• Description and quantity of contents per package
• Shipping marks and container numbers

3. Bill of Lading or Air Waybill

The bill of lading (B/L) is both a receipt for cargo and a document of title. For sea freight, it is issued by the shipping line or freight forwarder. For air freight, an air waybill (AWB) is used instead. The B/L must match the shipper, consignee, notify party, port of loading, port of discharge and cargo description on the invoice.

• Shipper, consignee and notify party details
• Vessel name, voyage number and sailing date
• Port of loading and port of discharge
• Number of packages, gross weight and measurement
• Freight terms: prepaid or collect

4. Mill Test Certificate (MTC)

The mill test certificate is the technical passport of the steel. It proves that the material meets the ordered grade, standard and mechanical requirements. Many customs authorities and end users will not accept steel without an MTC.

• Heat number and batch number
• Steel grade and applicable standard
• Chemical composition
• Mechanical test results: tensile, yield, elongation, hardness
• Dimensional inspection results
• Standard reference: EN 10204 3.1 or 3.2

For high-risk or regulated applications, request EN 10204 3.2, which is countersigned by an independent inspection agency. For routine commercial shipments, EN 10204 3.1 issued by the mill is usually sufficient.

5. Certificate of Origin

The certificate of origin confirms the country where the goods were manufactured. It is required to claim preferential duty rates under free trade agreements and to determine whether anti-dumping or safeguard duties apply.

• Manufacturer name and address
• Description and HS code of goods
• Country of origin
• Chamber of commerce or authorized body stamp
• Signature and date

6. Inspection Certificate

When a third-party inspection agency such as SGS, Bureau Veritas or TÜV Rheinland checks the cargo, it issues an inspection certificate. This document adds credibility and is often required by banks under a letter of credit.

• Inspection scope: quantity, dimensions, visual, marking, sampling
• Reference standards and acceptance criteria
• Test results and photographs
• Inspector name, date and agency stamp

7. Insurance Certificate

Marine cargo insurance protects against loss or damage during transit. Under CIF terms, the seller arranges insurance. Under FOB or CFR terms, the buyer arranges it. The certificate should show coverage amount, risks covered, voyage details and beneficiary.

8. Import License and Customs Declaration

Some countries require an import license for steel products. The customs declaration must state the correct HS code, value, origin and duty preference. Supporting documents such as the MTC and certificate of origin should be ready for inspection.

Packing List	Seller	Weights, marks, packages	Yes
Bill of Lading / AWB	Carrier	Routing, consignee, cargo	Yes
Mill Test Certificate	Mill	Chemistry, mechanical results	Yes
Certificate of Origin	Chamber / Authority	Country of manufacture	Often
Inspection Certificate	Third-party agency	Quality/quantity verification	If L/C or contract
Insurance Certificate	Insurer	Coverage, voyage, beneficiary	If CIF or required
Import License	Buyer / Government	Permission to import	If regulated

10. Common Mistakes to Avoid

• HS code mismatch: The code on the invoice must match the actual product form and grade.
• Inconsistent descriptions: Avoid calling the same product “steel plate” on the invoice and “hot-rolled coil” on the B/L.
• Missing MTC: Always request the certificate before shipment; requesting it afterwards causes delays.
• Wrong origin: Transshipment through a third country does not change the country of origin.
• Expired certificates: Some inspection certificates have validity periods; ensure they cover the shipment date.

11. Frequently Asked Questions

11.1 What is the most important document for carbon steel imports?

The mill test certificate is usually the most important technical document because it proves the steel meets the ordered grade and standard. Without it, the buyer cannot verify material quality.

11.2 Do I need a certificate of origin for every shipment?

If you want to claim a preferential duty rate or if the destination country applies origin-specific duties, a certificate of origin is essential. Even without preferences, many customs authorities request it.

11.3 What is the difference between MTC 3.1 and 3.2?

EN 10204 3.1 is issued by the mill based on its own testing. 3.2 is validated by an independent inspector who witnesses the testing or reviews the mill’s records. Use 3.2 for critical applications or when the contract requires it.

11.4 Can missing documents cause customs seizure?

Yes. Repeated or serious documentation errors can lead to cargo holds, fines and even seizure. Preparing a document checklist and reviewing paperwork before shipment reduces this risk significantly.
