Bill of Lading Requirements for Steel and Metals Trade

Introduction

A bill of lading for steel and metals shipments must satisfy both the UCP 600 transport-document requirements and the specific weight, quantity, and condition conventions used in the metals trade. Steel products are typically shipped in bulk or on break-bulk vessels, and the bill of lading frequently incorporates "said to contain" or "weight unknown" clauses because the carrier does not independently verify the weight or condition of the cargo. A current Google News scan found reporting from Trade Finance Global about HSBC and Tata Steel executing a blockchain-enabled, paperless trade transaction for steel, representing a development in how steel trade documents are processed. That reporting is operational context, not legal authority. The compliance decision remains governed by the credit text, UCP 600, and applicable ISBP 745 guidance.

Failure Mode Analysis

Failure Mode 1: Bill of lading weight conflicts with invoice weight beyond tolerance

If the bill of lading states a weight that differs from the commercial invoice by more than the tolerance allowed in the credit (typically plus or minus 5%), the examiner may raise a discrepancy. For bulk steel shipments, weight differences are common due to moisture, measurement methods, and the "weight unknown" clause. The credit should specify the applicable tolerance; if it does not, the examiner applies the standard tolerance under ISBP 745.

Failure Mode 2: "Clean" bill of lading required but claused

A "claused" bill of lading (one that notes damage or deficiency in the goods) is a discrepancy if the credit requires a "clean" bill of lading. For steel products, surface corrosion, bending, or packaging damage may result in a claused bill. The exporter should address the condition of the goods before loading to obtain a clean bill.

Failure Mode 3: On-board date after latest shipment date

A bill of lading issued before loading may have an on-board notation dated after the latest shipment date specified in the credit. The on-board date is the shipment date; the issuance date is the date the carrier received the goods. Article 20 distinguishes these dates. An on-board date after the latest shipment date is a discrepancy.

Failure Mode 4: Multiple originals not presented

Article 20(a)(vii) requires the bill of lading to state the number of originals. If the credit requires presentation of all originals and the exporter presents only one, the presentation is incomplete. For steel shipments, multiple originals may be required for customs clearance at the destination.

Failure Mode 5: Bill of lading does not reflect the actual vessel or port

A bill of lading that names a vessel or port inconsistent with the credit terms is a discrepancy. For steel shipments involving transshipment, the bill of lading may need to reflect the transshipment port and the final destination port separately.

Deterministic Resolution Architecture

1. Review the credit to identify the required type of bill of lading (on board, received for shipment, clean) and any specific clauses (weight verification, loading terms).
2. Confirm that the bill of lading is issued by the carrier named in the credit and signed in the required capacity.
3. Verify that the on-board date or received-for-shipment date is within the latest shipment date specified in the credit.
4. Check the weight stated on the bill of lading against the commercial invoice and any certificate of weight to confirm consistency within the applicable tolerance.
5. If the credit requires a clean bill of lading, confirm that no clausing or notes appear on the document regarding the condition or quantity of the goods.
6. Present all originals of the bill of lading as required by the credit and Article 20(a)(vii).
7. Verify that the vessel name, port of loading, and port of discharge on the bill of lading match the credit terms.
8. If the bill of lading incorporates a "said to contain" or "weight unknown" clause, confirm that the credit does not require the carrier to verify the weight or quantity independently.

Conclusion

The bill of lading for steel and metals shipments combines the standard UCP 600 transport-document requirements with the practical realities of bulk cargo handling. Weight discrepancies, clausing, and "weight unknown" clauses are common in the metals trade and are addressed by ISBP 745. The key controls are the on-board date, the weight consistency within tolerance, the clean status of the document, and the correspondence between the bill of lading and the other stipulated documents.

FAQ

Is a "weight unknown" clause on the bill of lading a discrepancy?

No, if the credit does not require the carrier to verify the weight. ISBP 745 Paragraph C21 confirms that a "said to contain" or "weight unknown" clause is not inconsistent with the credit if the credit does not require carrier verification of weight or quantity.

What tolerance is acceptable for weight differences between the bill of lading and the invoice?

The credit should specify the tolerance. If the credit is silent, ISBP 745 allows a standard tolerance (typically plus or minus 5%) for quantity and weight, subject to the total amount not exceeding the credit limit.

Can a blockchain-based bill of lading satisfy UCP 600?

UCP 600 does not specifically address electronic transport documents. The eUCP supplement addresses electronic records. If the credit incorporates eUCP, a blockchain-based bill of lading may satisfy the credit terms. If the credit does not incorporate eUCP, a traditional paper bill of lading is required.

What happens if the bill of lading is claused but the credit requires a clean bill?

A claused bill of lading is a discrepancy if the credit requires a clean bill. The exporter should address the condition of the goods before loading or obtain a letter of indemnity from the applicant to waive the discrepancy, if the applicant is willing.

Does the bill of lading need to state the steel grade or specification?

The credit governs the required content. If the credit does not require the bill of lading to state the steel grade, the absence of this information is not a discrepancy. The steel grade is typically stated on the commercial invoice and the certificate of analysis.
