Letter of Credit (LC) vs. Cash-against-Documents (CAD)

Feature Letter of Credit (LC) Cash-against-Documents (CAD / D/P)
Core idea Buyer’s bank promises to pay the seller once a pre-agreed document set exactly matches LC terms. Seller ships and mails the negotiable B/L to their bank; buyer can claim documents (and thus the cargo) only after paying the draft.
Risk carried by Bank (for buyer’s solvency) once documents are compliant; seller for documentary discrepancies. Seller carries buyer default risk until payment; buyer can inspect docs before paying.
Working-capital impact Money arrives on presentation (sight LC) or at tenor (usance LC). Discounting possible. Funds released when ship reaches destination & buyer pays—typical 7-30 days longer cash gap for seller.
Cost 0.5 – 1.5 % of face value (opening, confirmation, negotiation, discrepancies). 0.1 – 0.4 % (collection handling fee) + courier.
Typical use cases New counter-party; large cargo (≥ USD 0.5 M); politically risky buyer country; bank-financed deal. Repeat counter-party; modest cargo; buyer has strong credit but wants to avoid LC costs.
Key documents Commercial invoice, clean on-board B/L, packing list, COO, insurance (if CIF/CIP), inspection/COA. Similar set but bank only checks for completeness, not wording compliance.
Common pitfalls Tiny doc errors → bank refusal; shipment must stay within LC validity; extra drafts needed for ±10 % quantity. Buyer delays payment to leverage demurrage; if buyer disappears, seller must reroute or liquidate cargo elsewhere.
Variations – Sight vs Usance - Confirmed LC (2nd bank guarantee) - Transferable / Back-to-Back - Standby LC – Documents against Acceptance (D/A): buyer accepts a time draft instead of paying sight.

For seller, LC funds arrive 1–2 weeks earlier than CAD.


2  When to insist on an LC

  • First shipment with a new buyer or into sanction-prone / high-FX-control country.

  • Cargo value above your credit-insurance single-risk limit.

  • Long transit (> 30 days) where buyer could become insolvent before cargo lands.

  • Financing your purchase with a bank—lenders normally require an LC or SBLC.


3  When CAD is perfectly fine

  • Stable relationship (≥ 3 cargoes) and buyer provides audited financials.

  • Regional trade in GCC/EU where legal enforcement is predictable.

  • Low-value containers or samples.

  • Seller keen to stay price-competitive: cutting the LC fee can shave 1.5-0.5 % off landed cost.


4  Hybrid solutions

  • LC for first two lots, switch to CAD once performance proven.

  • Standby LC: cheaper than a documentary LC; only drawn if buyer defaults on CAD payment.

  • Insurance + CAD: seller buys trade-credit insurance (≈ 0.3 – 0.6 %) to hedge buyer default, still cheaper than a confirmed LC.


5  Negotiation tips

  • Seller: request sight LC but offer a 1 % price discount for CAD—makes cost trade-off explicit.

  • Buyer: agree to LC but cap discrep­ancy fees on first cargo; push to convert to CAD after on-time payment history.

  • Both: align Incoterm & risk; if using CIF, seller’s LC presentation must include insurance certificate.

  • Write a clear discrepancy cure clause (“bank may cable correct docs, fee USD 50 borne by seller”) to avoid full rejection over minor typos.
