Anyone running offshore resale trades needs to re-read the foreign-exchange rulebook. Under Article 14 of the Guidelines on Foreign Exchange Business for Trade in Goods, a single offshore resale transaction should in principle be settled at one bank in one currency. Cross-bank or cross-currency deals require prior confirmation of authenticity and legality, and the cover note for the cross-border receipt/payment declaration must carry the remark "special offshore resale," reported to the foreign-exchange authority within five working days of the transaction.

This has direct settlement implications for SNSUC's seven transshipment grades — ESPO, Dubai, Oman, Urals, Basrah Light, Bonny Light and Lula. When title changes hands offshore but funds clear through an onshore bank, the old habit of splitting settlements across banks breaks the paperwork and the reporting clock; at best the declaration bounces, at worst the account lands on enhanced monitoring.

The cleanest structure is to keep the letter of credit, the receipt/payment and the conversion all at one qualified bank, in one currency — dollars or yuan, but not a mix. Where a currency switch is unavoidable, assemble the trade-background memo, bill of lading and inspection certificate upfront, and tag the declaration "special offshore resale" on the day, not when the five-day window is about to close.

Customer classification matters too. Only A-class enterprises typically clear entrepot receipts and payments smoothly; B and C classes get flagged. Screening a counterparty's economic substance at onboarding beats answering a regulator's query later.
