Difference Between UCP 600, ISP98, and URDG 758

Teams lose time and money when they pick the wrong rule set for the instrument they are issuing. UCP 600, ISP98, and URDG 758 are not interchangeable labels. They control how documents are examined, how claims are presented, what notice process applies, and where disputes start.

If your transaction includes a commercial Letter of Credit, a standby instrument, or a demand guarantee, your first risk decision is rule selection, not pricing.

Fast rule-of-thumb: UCP 600 is built for documentary credits, ISP98 is built for standby practice, and URDG 758 is built for demand guarantees.

In live mandates, we see mixed drafting where the instrument name says one thing and the legal mechanics say another. That is where claim friction starts.

What Each Ruleset Is Built To Do

UCP 600

  • Primary use: documentary credits in trade transactions.
  • Focus: document compliance against LC terms.
  • Typical context: shipment-related payment undertakings.
  • Can be applied to standbys when incorporated, though not drafted as a standby-first framework.

ISP98

  • Primary use: standby letters of credit.
  • Focus: standby lifecycle, demand mechanics, expiry handling, and presentation practicality.
  • Typical context: performance support, payment backstop, and long-dated contingent undertakings.
  • Designed to address standby-specific scenarios that appear less directly in UCP practice.

URDG 758

  • Primary use: demand guarantees and counter-guarantees.
  • Focus: complying demand workflow, role definitions, and guarantee-side discipline.
  • Typical context: construction, infrastructure, performance guarantees, and cross-border corporate obligations.
  • Modernized framework with clearer handling standards than older guarantee rulebooks.

Practical Bottom Line

  • Instrument naming does not control outcome. Drafting and incorporated rules do.
  • Do not assume your counterparty interprets terms the same way your team does.
  • Map the instrument to the real commercial function before issuance.

Operational Comparison For Credit And Legal Teams

Decision Point UCP 600 ISP98 URDG 758
Core Instrument Type Documentary credits (commercial LCs) Standby letters of credit Demand guarantees and counter-guarantees
Primary Draw Logic Document presentation under credit terms Complying demand logic tailored to standby use Complying demand logic tailored to guarantee use
Document Examination Clock Up to five business days in standard practice Reasonable-time structure under ISP98 rules, commonly managed in a narrow banking-day window Fixed examination disciplines for guarantees under URDG framework
Renewal Orientation Not naturally drafted around evergreen standby behavior Standby renewal and extension mechanics are more directly addressed Guarantee lifecycle and extension logic are core to drafting structure
Best Fit Shipment and trade document payment structures Contingent payment backstops and performance standbys On-demand guarantee structures and guarantee chains

Key execution point: Your legal and credit team should agree on one governing framework, then harmonize wording, notice mechanics, expiry language, and claim documents to that framework. Mixing concepts from two rule sets in one instrument invites preventable disputes.

Can A Standby Be Drafted Under URDG 758?

Market practice can blur names. Some instruments get marketed as "SBLC" while drafted with guarantee-style language and URDG governance. This can be valid if the structure is intentional, negotiated, and understood by all parties.

The problem is lazy drafting. If one side expects standby behavior and the text produces guarantee behavior, draw-stage conflict is predictable. The label on page one does not save the file.

Where Transactions Break

1) Misfit Between Instrument And Rules

Documentary mechanics inside a standby commercial context, or standby assumptions inside guarantee drafting, creates avoidable rejection risk.

2) Conflicting Clauses

Custom clauses that quietly override incorporated rules can nullify expected protections.

3) Weak Demand Language

If demand wording is vague, notice protocols and claim formatting become a battleground.

4) Expiry And Presentation Errors

Unclear place, time, or language requirements can kill an otherwise valid claim.

Hard truth: most failures are drafting and process failures, not product failures. Teams usually discover this at the worst possible time, during a stressed draw.

Pre-Issuance Checklist

  1. Confirm the real function of the instrument in the underlying contract.
  2. Select one governing ruleset that matches that function.
  3. Draft demand and supporting document language with no cross-framework conflict.
  4. Set clear expiry date, place of presentation, and bank business-day handling.
  5. Align language, notice channel, and signature formalities.
  6. Stress-test claim scenarios before issuance, not after default.

FAQ

Is UCP 600 only for commercial documentary credits?

It is built for documentary credits. It can also apply to standbys when expressly incorporated in the instrument text.

Why choose ISP98 for standby instruments?

ISP98 is standby-specific, so it usually gives cleaner treatment for standby lifecycle issues, claims, and expiry handling.

What is URDG 758 used for?

URDG 758 is the standard framework for demand guarantees and counter-guarantees in cross-border guarantee practice.

Can an instrument called SBLC use URDG 758?

Yes, parties can agree to that structure. The key is that the full text and mechanics must be consistent with the chosen framework.

What is the biggest drafting mistake?

Mixing clauses from different frameworks without resolving conflicts in demand, notice, and examination language.

Do these rules replace local law?

No. They are contractual rule sets incorporated by agreement. Local law and court or arbitral interpretation still matter.
