Common LC Discrepancies Under UCP 600 (and How Banks Refuse)

A bank does not pay because the shipment was real or because the buyer meant well. It pays because the document set matches the credit on its face. Under UCP 600, a single qualifying mismatch gives the issuing bank a clean legal basis to refuse — and most refusals are entirely preventable before the documents ever reach the banking channel.

Industry estimates have long put first-presentation discrepancy rates somewhere around half of all documentary credits. Whether the real figure in any given corridor is 40 percent or 70 percent, the practical lesson is the same: discrepancies are the norm, not the exception, and the exporter who treats compliance as an afterthought is the one who ends up waiting on a waiver that may never come. This page covers the discrepancies that actually trigger refusals, the UCP 600 mechanics behind each one, and a pre-check workflow built to catch them while there is still time to fix the set.

Why Discrepancies Happen in the First Place

A letter of credit looks simple: ship the goods, present the documents, get paid. In practice the credit becomes a strict checklist, and the bank's job is narrow by design. Under UCP 600 Article 14(a), the nominated bank, confirming bank, and issuing bank examine a presentation "on its face" to determine whether the documents appear to constitute a complying presentation. The bank is not auditing the trade. It is comparing paper against terms.

Most discrepancies are not bad faith. They are drafting mistakes, operational misunderstandings, or documents produced by third parties — freight forwarders, insurers, inspection agencies — who are working from their own templates rather than from the credit. The exporter follows the commercial contract. The bank follows the credit. When the two are not aligned, the exporter is trapped between two rulebooks, and only one of them controls payment.

Practical rule: the letter of credit is the payment rulebook. The sales contract is not what the bank pays against, and "but the contract says" is not a cure for a non-compliant presentation.

The UCP 600 Mechanics You Need to Understand

Before the list of discrepancies, it helps to understand the three articles that decide whether you get paid. Almost every refusal traces back to one of them.

  • Article 14 — the standard of examination. Banks have a maximum of five banking days following presentation to examine and decide. Documents must not conflict with each other, with the credit, or with the standard the credit sets. Crucially, data in a document does not need to be identical to the credit or to other documents, but it must not be in conflict — a tolerance that exporters routinely misjudge in both directions.
  • Article 18 — commercial invoices. The description of goods on the invoice must correspond with the description in the credit. This is stricter than the general "no conflict" standard applied to other documents, which is why invoice description mismatches are the single most common refusal trigger.
  • Article 16 — the refusal procedure. If a bank decides to refuse, it must send a single notice no later than the close of the fifth banking day, state each discrepancy it is refusing on, and say what it is doing with the documents. Miss any of those steps and the bank is precluded from claiming the documents are discrepant. This article cuts both ways — it disciplines the bank, but it also means once a valid notice lands, your remedies narrow to waiver, correction and re-presentation, or losing the protection of the credit.

The Most Common LC Discrepancies

Discrepancy Type What It Looks Like How To Prevent It
Goods Description Mismatch Invoice wording differs from the credit. Shortened descriptions, added marketing terms, or different model numbers breach the Article 18 correspondence requirement. Mirror the credit's goods description on the invoice. Keep extra commercial text off the invoice unless the credit clearly permits it.
Quantity, Weight, or Unit Conflicts Different units across documents, rounding differences, net versus gross weight conflicts, or totals that do not reconcile across the set. Standardize units at the drafting stage and reconcile every total across invoice, packing list, and certificates before presentation.
Late Shipment or Late Presentation Shipment date after the latest shipment date, or presentation after the period allowed by the credit. Where no period is stated, Article 14(c) caps presentation at 21 calendar days after shipment, and never later than expiry. Run deadlines like a closing calendar. Build buffer for weekends, port delays, and third-party document issuance. Confirm the 21-day rule does not silently apply.
Transport Document Problems Wrong consignee or notify party, missing endorsements, a claused bill of lading, missing on-board notation, or incorrect port-of-loading and port-of-discharge fields. Confirm the exact transport-document format the credit requires (Articles 19 to 25 govern these) and instruct the forwarder in writing before the goods move.
Insurance Errors Coverage below the required percentage, wrong risks, wrong currency, or a cover date later than the shipment date. Article 28(f)(ii) sets a default minimum of 110 percent of CIF or CIP value where the credit is silent. Hand the broker the exact insurance clause, validate the coverage math against invoice value, and confirm the policy is effective no later than the shipment date.
Certificate Requirements Not Met Certificates of origin, inspection, or analysis with missing fields, the wrong issuer identity, an unauthorized signatory, or wording that departs from the credit. Use pre-approved templates and confirm issuer identity and signing authority before shipment, not after the certificate is issued.
Inconsistent Names and Addresses Different spellings, abbreviations, or addresses across documents, especially between the invoice and the transport document — a classic Article 14 conflict. Build one master data sheet and copy from it into every document. Never retype the same field twice from memory.
Missing or Incorrect Originals and Copies The credit requires a set number of originals or copies and the presentation is short, over, or incorrectly marked as original versus copy. Add copy counts and marking requirements to the document matrix before you prepare a single page. Article 17 governs what counts as an original.
Stale or Internally Inconsistent Dates Certificate dated after shipment, inspection performed after loading, or an invoice date that contradicts the transport document. Sequence the dates logically and cross-check them as a chain. The story the dates tell must be physically possible.
The most expensive mistakes are rarely dramatic. They are small mismatches — a missing endorsement, a unit conflict, an extra line on the invoice — that hand the issuing bank a clean technical basis to refuse a payment that everyone involved knows is commercially due.

What a Discrepancy Actually Costs You

Exporters underestimate discrepancies because the headline outcome — "the bank refused" — sounds reversible. It often is, but reversal is neither free nor fast. Once a valid Article 16 refusal notice is issued, you are looking at some combination of the following.

  • A discrepancy fee deducted by the issuing or confirming bank, typically in the range of USD 75 to USD 150 per presentation, charged simply for the privilege of being refused.
  • Loss of LC protection. The moment documents are discrepant, payment depends on the applicant agreeing to waive. You have effectively converted a bank obligation into an open-account exposure to your buyer, with all the counterparty risk that implies.
  • Time and financing cost. Correcting and re-presenting documents can add days or weeks. If you have discounted or borrowed against the expected proceeds, that delay carries a real funding cost and can breach your own covenants.
  • Leverage handed to the buyer. A buyer who knows your documents are discrepant and that the market has moved against them has every incentive to renegotiate price, demand a discount, or walk. The discrepancy is the opening they were waiting for.

A Pre-Check Workflow That Prevents Refusals

A pre-check is not generic proofreading. It is a structured review designed to surface bank-facing issues before documents enter the banking channel, while there is still time to correct them at near-zero cost. The four steps below are the core of the process.

1) Build a Document Matrix

Extract every required document from the credit and capture, for each one, the issuer, the required wording, the signature rules, the relevant dates, and the original-versus-copy counts. This matrix becomes the single source of truth for the presentation.

2) Lock a Master Data Sheet

Fix names, addresses, the goods description, quantities, and reference numbers in one place and copy from it into every document. This kills the cross-document drift that drives Article 14 conflicts.

3) Validate Every Deadline

Cross-check the latest shipment date, the presentation period (or the 21-day default), the expiry date, and any special timing clauses. Confirm that third-party issuers can actually meet their slots in the chain.

4) Reconcile the Full Set

Reconcile totals, dates, descriptions, and key fields across the invoice, packing list, transport document, insurance, and certificates as one coherent file before anything is presented.

If you are settling at sight, the process is even less forgiving — there is no usance period to absorb a correction cycle. Our sight payment letter of credit advisory service is built around pre-issuance review and pre-presentation checks specifically to take refusal risk and timing delays off the table.

Frequently Asked Questions

What is the most common LC discrepancy?

Goods description mismatches between the commercial invoice and the credit. UCP 600 Article 18 requires the invoice description to correspond with the credit, a stricter standard than the general "no conflict" rule applied to other documents, so even small wording changes trigger refusal.

Can a bank refuse documents even if the shipment is correct?

Yes. Under Article 14, banks examine documents on their face, not the underlying trade. A correct cargo does not cure a non-compliant presentation, and the bank has no obligation to look past the paper.

How many days does a bank have to examine documents?

Article 14(b) gives each bank a maximum of five banking days following the day of presentation to determine whether a presentation complies. If it refuses, the Article 16 notice must be sent within that same window.

What happens if the bank misses the Article 16 deadline?

If the bank fails to send a conforming refusal notice within five banking days, it is precluded from claiming the documents are discrepant and must honor or negotiate the presentation. The discipline runs in both directions.

How do exporters reduce refusal risk fast?

Align the credit wording with the contract before the credit is issued, then run a structured pre-check before presentation using a controlled document matrix and a single master data sheet. Prevention is far cheaper and faster than refusal recovery.

Is waiver negotiation a reliable strategy?

No. A waiver depends entirely on the applicant's willingness and the issuing bank's process, and it converts a bank obligation back into buyer counterparty risk. Treat it as a last resort, never as a plan.
