Letter of Credit Structuring for First-Time China Sourcing Buyers

Why this matters

For a first-time buyer of Chinese pipe fittings, the letter of credit (L/C) is the bridge between "I do not know this supplier" and "the bank will only pay against documents that prove performance." UCP 600 — the ICC's Uniform Customs and Practice for Documentary Credits — governs L/Cs in 175 countries and roughly USD 1 trillion of trade per year. A poorly structured L/C either pays a bad supplier (because the document list is too thin) or blocks payment to a good supplier (because the document list is impossible). This guide structures a clean L/C for first-time China sourcing under UCP 600.

A letter of credit structuring approach grounded in UCP 600 protects both buyer and seller on the first PO.

Field-by-field L/C structure

1. Type of credit. Irrevocable, sight (or usance, e.g., 60 days after sight). Confirmed by a first-class bank in the seller's country if seller is unfamiliar with the buyer's bank.

2. Amount and currency. Match the proforma invoice. Add a tolerance ("+/- 5%" or "about") if the cargo is bulk-priced.

3. Beneficiary and applicant. Exact legal name and address as registered. Mismatches here are the #1 discrepancy cause.

4. Latest shipment date and expiry. Allow at least 21 days between shipment and expiry — UCP 600 Article 14(c) requires documents be presented within 21 days of shipment by default and within validity.

5. Incoterms. State "FOB Tianjin Incoterms 2020" or equivalent so freight/insurance liability is unambiguous.

6. Partial shipment and transhipment. Allowed or prohibited. For a single PO of pipe fittings, partial shipments are usually allowed because a full container may not be ready in one batch.

7. Document list. Keep it lean. UCP 600 best practice is to require an invoice and transport document; add only documents you genuinely need:

• Signed commercial invoice (3 originals)
• Full set 3/3 clean on-board ocean bill of lading consigned "to order of [bank]"
• Packing list
• EN 10204 3.1 Mill Test Certificate
• Certificate of Origin (Form A or general, depending on country)
• Pre-Shipment Inspection Report by [TPI agency] (when used)
• Insurance policy/certificate for 110% of CIF value (if CIF)
• Beneficiary's certificate that one set of non-negotiable documents has been couriered to applicant

8. Description of goods. Match the proforma exactly. UCP 600 Article 18(c) says invoice description must correspond with the credit; other documents may use a general description.

9. Discrepancy handling. Specify acceptable response times and that minor discrepancies (typos, page numbering) are acceptable on negotiation. "At sight" L/Cs typically allow 5 banking days for issuing bank examination per UCP 600 Article 14(b).

10. Charges. Who pays which side's charges ("all charges outside opening bank for beneficiary's account" is common).

Common buyer mistakes

• Asking for too many documents ("vessel age certificate", "shipping company ownership certificate") that no carrier will issue — guaranteeing discrepancy.
• Setting expiry the same day as latest shipment, leaving zero presentation window.
• Forgetting to allow partial shipment, then refusing to amend when the seller is ready to ship 80%.
• Not confirming the L/C in the seller's country when first dealing with a small Chinese mill.
• Misnaming the beneficiary's bank — payment routing fails.
