ISBP 745 Section G: Weight Certificate Requirements — When Is It Required and What Must It Contain?

Introduction

A certificate of weight is one of the most common documents required in documentary credits for bulk commodities, raw materials, and goods sold by weight. ISBP 745 Section G establishes what a weight certificate must contain and how the examining bank evaluates it. The credit may require a weight certificate as a standalone document, or it may require a weight certificate from a specific party (e.g., an independent surveyor). Understanding when the certificate is required and what it must show is essential for compliance.

Failure Mode Analysis

FM1: Credit Requires Weight Certificate, No Certificate Presented

If the credit requires a weight certificate and the beneficiary does not present one, the presentation fails under Article 14(a) — a stipulated document is missing. The absence of the certificate cannot be cured by data on the invoice or other documents.

FM2: Weight Certificate Shows Only Net Weight

Under ISBP 745 G1, the certificate should indicate gross, net, and tare weight. If the certificate shows only net weight, the bank may refuse under G1. The completeness requirement depends on the credit's specific language — if the credit requires a "gross weight certificate," only gross weight is required.

FM3: Weight Certificate from the Beneficiary Instead of an Independent Party

When the credit requires a certificate from an independent surveyor and the beneficiary presents a self-issued weight certificate, the presentation fails. The certificate must come from the party specified in the credit.

FM4: Weight Certificate Dated After the Shipment Date

A weight certificate dated after the shipment date raises questions about whether the weight was measured at the time of shipment. While ISBP 745 does not explicitly require the weight certificate to be dated before or on the shipment date, a certificate dated significantly after shipment may not satisfy the credit's intent.

FM5: Weight Unit Mismatch

If the credit specifies "metric tonnes" and the certificate shows "kilograms," the presentation fails. The bank examines the unit as stated. Even if 5,000,000 kg equals 5,000 MT, the mismatch in units is a discrepancy.

Deterministic Resolution Architecture

Step 1: Confirm Whether the Credit Requires a Weight Certificate

Read the credit's document requirements. Identify whether the credit states "weight certificate," "certificate of weight," "independent weight certificate," or similar. If the credit does not require a weight certificate, no weight certificate need be presented.

Step 2: Identify the Specified Issuer

If the credit requires a weight certificate from a specific party (e.g., "weight certificate issued by independent surveyor"), confirm that the certificate comes from that party. A self-issued certificate does not satisfy this requirement.

Step 3: Verify the Weight Data Completeness

Under ISBP 745 G1, check whether the certificate shows gross, net, and tare weight. If the credit requires only gross weight, confirm that gross weight is shown. If the credit is general ("weight certificate"), apply the G1 standard — all three weight types should be present.

Step 4: Confirm the Unit of Measurement

Identify the unit stated on the certificate. Compare against the credit's specified unit. If the credit specifies MT and the certificate shows kg, the presentation fails. The unit must match.

Step 5: Cross-Reference Weight Against the Invoice

Compare the net weight on the certificate against the weight shown on the invoice under Article 14(d). The two documents must not conflict. Minor rounding differences may or may not be material — the examining bank applies judgment.

Step 6: Verify the Certificate Is Signed

Under ISBP 745 A20, the certificate must be signed by the issuing party. If the credit requires an independent party, the signature must be from that party. An unsigned certificate is a discrepancy.

Step 7: Confirm the Certificate Relates to the Shipment

The certificate must reference the correct goods, shipment, vessel (if applicable), and date. A certificate that references a different shipment or different goods does not satisfy the credit's requirement.

Conclusion

A weight certificate under ISBP 745 Section G must contain the weight data the credit requires, in the unit the credit specifies, from the party the credit names. The certificate must be signed, must not conflict with the invoice, and must relate to the credit's transaction. When the credit requires a weight certificate and the beneficiary does not present one — or presents an incomplete or non-compliant certificate — the presentation fails. Pre-presentation verification against Section G standards prevents the most common weight-certificate discrepancies.

FAQ

Q1: Is a weight certificate always required for bulk commodity credits?

Not always. The requirement depends on the credit's specific document list. However, most bulk commodity credits require a weight certificate because weight is the primary measurement for pricing and customs purposes.

Q2: Can the beneficiary self-issue the weight certificate?

Only if the credit permits it. If the credit requires the certificate from an independent party (e.g., "certificate issued bySGS"), the beneficiary cannot self-issue. If the credit is silent on the issuing party, the beneficiary may issue its own weight certificate.

Q3: What if the weight certificate shows a slightly different weight than the invoice?

Under Article 14(d), the weight must not conflict. Minor rounding differences (e.g., 5,000.2 MT vs 5,000 MT) are typically acceptable. Material differences (e.g., 4,800 MT vs 5,000 MT) are discrepancies.

Q4: Does the weight certificate need to be original?

UCP 600 requires presentation of originals unless the credit states otherwise. A weight certificate that is a copy (not an original) may be refused under Article 17.

Q5: Can the weight certificate be combined with the inspection certificate?

Yes, if the credit allows it and the weight data is clearly identifiable under ISBP 745 G3. A combined certificate must separate the weight data from the inspection data so the bank can verify each independently.

Q6: What happens if the weight certificate is dated after the latest shipment date?

UCP 600 does not require the weight certificate to be dated before or on the shipment date. However, a certificate dated after shipment may raise questions about whether the weight measurement reflects the actual shipment. The examining bank may accept it if the certificate appears to relate to the correct shipment.
