What UCP 600 Is

A documentary credit is a bank's independent undertaking to pay the seller against presentation of specified documents. UCP 600 is the rulebook that gives that undertaking predictable content. It is not legislation — it applies because the credit says it does, and virtually every credit issued does say so.

For an exporter, UCP 600 is the difference between a payment promise from a bank and a payment promise from a buyer. It is worth understanding the handful of articles that actually decide outcomes.

The Two Governing Principles

Autonomy — Article 4

A credit is by its nature a separate transaction from the sale contract on which it may be based. Banks are in no way concerned with or bound by that contract, even if a reference to it is included in the credit. So the buyer cannot stop payment simply by alleging the goods are defective. The exporter's right to be paid depends on the documents, not on the commercial dispute.

Documents, not goods — Article 5

Banks deal with documents and not with goods, services or performance. This is the mirror image of autonomy, and it cuts both ways: the exporter cannot be denied payment because of a quality argument, and equally cannot be paid on perfect goods with imperfect documents.

The Articles That Decide Payment

ArticleWhat it fixes
14(a)Documents are examined on their face to determine whether they constitute a complying presentation
14(b)A maximum of five banking days following the day of presentation to examine and decide
14(c)Presentation with original transport documents no later than 21 calendar days after shipment, and within the credit's expiry
14(d)Data need not be identical across documents, but must not conflict
14(e)In documents other than the commercial invoice, goods may be described in general terms not conflicting with the credit
16Refusal procedure — a single notice, stating each discrepancy and the disposal of the documents
18Commercial invoice — must be issued by the beneficiary and describe the goods as in the credit
20Bill of lading requirements — carrier identification, on-board notation, port to port
28Insurance documents — coverage at least 110% of CIF or CIP value where the credit is silent
30Tolerances — "about" or "approximately" permits ±10%; a 5% quantity tolerance in defined cases

Strict Compliance in Practice

Article 14(d) softened the old doctrine: data in a document need not be identical to the credit or to other documents, but must not conflict. That is a real relaxation, and it removes the most trivial category of rejection.

It does not, however, make presentation forgiving. Discrepancies that still defeat presentations, day in and day out:

  • Goods description on the invoice not matching the credit's description
  • Late presentation — beyond 21 days of shipment or after expiry
  • Late shipment — after the latest shipment date in the credit
  • Bill of lading without a proper on-board notation, or not evidencing the required ports
  • Insurance for less than 110%, or in a currency other than the credit's
  • Insurance dated after the shipment date
  • Missing document simply not presented
  • Inconsistent weights or quantities between packing list, invoice and transport document
  • Beneficiary or applicant name spelt differently across documents

The Refusal Procedure — Article 16

If the bank decides to refuse, it must give a single notice, by telecommunication or other expeditious means, no later than the close of the fifth banking day following presentation. That notice must state that the bank is refusing, state each discrepancy, and state what the bank is doing with the documents — holding them pending instructions, holding pending a waiver from the applicant, returning them, or acting on previously received instructions.

A bank that fails to act in accordance with Article 16 is precluded from claiming that the documents do not comply. This is a genuine protection: check the timing and completeness of any refusal notice you receive.

Types of Credit an Exporter Meets

TypeWhat it gives you
Irrevocable creditCannot be amended or cancelled without the beneficiary's agreement — the default under UCP 600
Confirmed creditA second bank, usually in the exporter's country, adds its own undertaking — removes issuing bank and country risk
Sight creditPayment on complying presentation
Usance / deferred payment creditPayment at a determinable future date — the exporter grants credit but against a bank undertaking
Transferable creditCan be made available in whole or part to a second beneficiary — used by intermediaries
Back-to-backA second credit issued on the strength of the first — commercially useful, operationally demanding
Revolving creditReinstates automatically for repeat shipments under a running contract
Red clause creditPermits an advance to the beneficiary before shipment

For markets in the weaker risk categories, confirmation is the single most valuable feature. An unconfirmed credit from a bank in a country facing exchange restrictions is only as good as that country's ability to remit.

A Working Method for Exporters

  1. Read the credit the day it arrives, before any goods move. Check the description, the latest shipment date, the expiry, the place of expiry, the documents required and any unusual conditions.
  2. Ask for amendments immediately for anything you cannot deliver — a certificate you cannot obtain, a shipment date you cannot meet, an expiry at the issuing bank's counters rather than in India.
  3. Build a document checklist from the credit text itself, in the credit's own words.
  4. Draft the invoice description verbatim from the credit. This is the one place identical wording is expected.
  5. Have someone else check the set against the checklist before presentation.
  6. Present early, leaving room to correct and re-present inside the 21 days and before expiry.

Practical Tips

  • Prefer expiry in India. An expiry at the issuing bank's counters means the documents must arrive there before expiry, which eats your margin for error.
  • Never accept a credit with a condition you cannot document — an inspection certificate signed by the buyer's nominee gives the buyer control over your payment.
  • Watch the insurance date. A policy dated after the on-board date is a routine and avoidable discrepancy.
  • Keep the presentation together. A missing document is not a discrepancy that can be argued away.
  • Where documents will be presented electronically, check whether the credit is subject to eUCP as well as UCP 600.

What is UCP 600?

The Uniform Customs and Practice for Documentary Credits, ICC Publication No. 600, in force since 1 July 2007. It is the set of rules that governs letters of credit worldwide when the credit states that it is subject to them, which almost all do.

How many days does a bank get to examine documents?

A maximum of five banking days following the day of presentation, under Article 14(b). If the bank does not send a refusal notice within that period it is precluded from claiming the documents are discrepant.

Over 90% of compliance penalties in India arise from missed due dates — timely handling can save businesses thousands of rupees each year.

Frequently Asked Questions
What is UCP 600?
The Uniform Customs and Practice for Documentary Credits, ICC Publication No. 600, in force since 1 July 2007. It is the set of rules that governs letters of credit worldwide when the credit states that it is subject to them, which almost all do.
How many days does a bank get to examine documents?
A maximum of five banking days following the day of presentation, under Article 14(b). If the bank does not send a refusal notice within that period it is precluded from claiming the documents are discrepant.
What is the 21-day rule?
Under Article 14(c), a presentation including one or more original transport documents must be made no later than 21 calendar days after the date of shipment, and in any event not later than the expiry date of the credit.
What does the autonomy principle mean?
Article 4 provides that a credit is a separate transaction from the sale contract it may be based on. Banks are not concerned with that contract, so a buyer's dispute about the goods does not by itself stop payment against complying documents.
What happens if documents are discrepant?
The bank may refuse. It must send a single notice by the fifth banking day stating each discrepancy and what it is doing with the documents. The exporter can then correct and re-present within the time limits, or ask the buyer to waive the discrepancies.
What insurance value does UCP 600 require?
Article 28(f)(ii) provides that where the credit is silent, the insurance document must be for at least 110% of the CIF or CIP value of the goods — which is why the market convention is to insure at invoice value plus ten per cent.
