UCP 600 Article 30: Examining Bills of Lading

Introduction

UCP 600 Article 30 establishes tolerance rules for credit amounts, quantities, and unit prices. When examining bills of lading in the context of Article 30, the key question is whether the quantity stated on the bill of lading falls within the applicable tolerance of the credit quantity. This guide examines how tolerance calculations interact with bill of lading examination under UCP 600 and ISBP 745.

Failure Mode Analysis

Failure Mode 1: Ignoring Tolerance When Assessing Bill of Lading Quantity

Banks sometimes reject bills of lading because the quantity shown differs from the credit quantity, without checking whether the difference falls within the applicable tolerance under Article 30.

Failure Mode 2: Applying Tolerance to Packing Units

Article 30(b) denies tolerance when the quantity is stated in terms of stipulated packing units or individual items. Banks that apply the 5% tolerance to a credit stating "500 cartons" violate this provision.

Failure Mode 3: Inconsistent Tolerance Application Across Documents

When the bill of lading shows a quantity within tolerance but the commercial invoice shows a different quantity also within tolerance, the bank must assess consistency per Article 14(d). If the two documents conflict, this may constitute a discrepancy.

Failure Mode 4: Tolerance Calculation Errors on Partial Shipments

For partial shipments, the tolerance applies to each individual drawing. Banks that calculate tolerance against the total credit quantity rather than the individual shipment quantity misapply Article 30.

Deterministic Resolution Architecture

1. Tolerance Applicability Check: Before examining the bill of lading quantity, determine the applicable tolerance: (a) 10% if "about" or "approximately" is used, (b) 5% if no variation prohibition and not in packing units, (c) 0% if variation is prohibited or quantity is in packing units.

2. Quantity Mapping: Map the bill of lading quantity to the credit quantity, calculating the percentage variance. Compare against the applicable tolerance.

3. Partial Shipment Tolerance: For partial shipments, apply the tolerance to the individual shipment quantity, not the cumulative credit quantity. Document the calculation for each drawing.

4. Cross-Document Consistency: Verify that the bill of lading quantity is consistent with the commercial invoice and packing list per Article 14(d). Assess whether any differences constitute conflicts.

5. Packing Unit Verification: Determine whether the credit quantity is stated in packing units or individual items. If so, confirm that the bill of lading quantity matches exactly, as no tolerance applies.

6. Documentation: Document the tolerance calculation, including the applicable provision, the variance percentage, and the conclusion on compliance.

7. Discrepancy Classification: If the bill of lading quantity is outside tolerance, classify the discrepancy specifically as a tolerance violation under Article 30, not a general quantity discrepancy.

Conclusion

Bill of lading examination under Article 30 requires systematic tolerance calculation. The applicable tolerance depends on the credit's language ("about" or "approximately"), whether variation is prohibited, and whether the quantity is stated in packing units. Correct tolerance application prevents wrongful refusals and ensures consistent examination across all documents.

FAQ

Q1: If the credit says "approximately 1,000 MT," is a bill of lading showing 1,050 MT acceptable?
A: Yes. Article 30(a) allows a 10% tolerance. 1,050 MT is within 10% of 1,000 MT (acceptable range: 900–1,100 MT).

Q2: If the credit says "500 cartons," can the bill of lading show 480 cartons?
A: No. Article 30(b) denies tolerance when the quantity is stated in packing units. The bill of lading must show exactly 500 cartons.

Q3: Does the tolerance apply to weight or just to quantity?
A: Article 30 applies to the quantity stated in the credit. If the credit states a weight (e.g., "1,000 MT"), the tolerance applies to that weight. If the credit states a number of units (e.g., "500 cartons"), the tolerance may not apply if they are stipulated packing units.

Q4: Can the bill of lading show a higher quantity than the credit allows even with tolerance?
A: Only if the higher quantity falls within the applicable tolerance. If the bill of lading shows 1,200 MT under a credit for 1,000 MT with 10% tolerance (acceptable range: 900–1,100 MT), the excess quantity is a discrepancy.

Q5: How does tolerance apply when the credit allows partial shipments?
A: The tolerance applies to each individual partial shipment, not to the cumulative total. Each bill of lading must show a quantity within the applicable tolerance of the individual drawing amount.
