Full Operation Guide for Import Agency Usance Letter of Credit: Compliance Pitfall Avoidance and Exchange Loss Control Practical Manual

Core Value and Mode Difference of Import Agency Usance Letter of Credit

Import agency usance letter of credit refers to a service mode that the import enterprise entrusts a qualified import and export agency to issue a usance letter of credit to the overseas seller on its behalf.This mode does not occupy the enterprise’s own bank credit line,and the enterprise can pay the payment after the goods arrive at the port and complete customs clearance,before the maturity of the L/C.It is suitable for small and medium-sized foreign trade enterprises with high capital turnover pressure,no import and export right,or insufficient L/C operation experience.

I have contacted many enterprises that operate usance L/C for the first time.Because they do not understand the difference between self-issued L/C and agency-issued L/C,they unnecessarily spent more than 100,000 RMB in extra cost.The core comparison between the two modes is as follows:

Core Practical Operation Points of Import Agency Usance LC in 2026

In 2026,the customs and the State Administration of Foreign Exchange have updated the regulatory requirements for import business under L/C.The following key points need to be focused on during operation:

• Pre-review and matching of HS Code: In 2026,GAC has updated the price assessment model for general goods and electromechanical products.It is necessary to complete HS Code classification in advance before L/C issuance,verify the consistency of declaration elements such as brand,model and material with the actual goods,to avoid document redemption delay caused by price assessment objection and extra port demurrage.
• Precise matching of usance L/C term and logistics cycle: When issuing the L/C,all factors including shipping schedule fluctuation,port inspection probability,and customs clearance delay at destination caused by holidays shall be fully calculated,and a buffer period of at least 20 days shall be reserved,to avoid overdue penalty caused by L/C maturity before the goods complete customs clearance.
• Consistency check of all documents: All information on commercial invoice,packing list,certificate of origin and bill of lading must be completely consistent with the L/C clauses and actual goods.In 2026,the spot check ratio for import goods under L/C at Shanghai Port has increased by 8%,once document discrepancy occurs,the goods will be detained directly,and the maximum extra document modification fee and port demurrage can reach tens of thousands of RMB.
• Pre-arrangement of exchange loss hedging plan: In 2026,the two-way fluctuation range of RMB exchange rate expands,the forward exchange settlement plan shall be confirmed synchronously at the L/C issuance stage,and lock the exchange rate cost combined with the payment term,to avoid extra expenditure caused by sharp exchange rate fluctuation.I have seen an enterprise losing nearly 300,000 RMB of exchange loss in a single order due to no forward exchange settlement arrangement.

Common Risk Warning for Import Agency Usance LC

The operation chain of usance L/C is long,involving multiple entities including SAFE,customs,banks and freight forwarders,which easily triggers compliance risks.The following red lines must be avoided:

The first one is the risk of arbitrage under false trade.It is strictly prohibited to construct transactions without real goods flow through usance L/C to arbitrage foreign exchange.Once verified by SAFE,the enterprise will be included in the control list,all subsequent import and export businesses will be subject to strict inspection,and serious cases will face fines or even criminal liabilities.

The second one is hidden cost trap.Many enterprises only pay attention to L/C issuance fee,ignoring the acceptance fee of usance L/C,document exchange fee and port demurrage,especially the manifest modification fee for European and American routes.Once document discrepancy occurs,the modification cost can be as high as 2000 USD per shipment,some bad freight forwarders will deliberately raise the document exchange fee,and enterprises without professional docking channels are very likely to be overcharged.

The third one is the risk of property right loss.If there is no professional customs clearance agency for self-issued L/C,problems such as delivery of goods without original B/L by freight forwarder,or defects in goods right transfer may occur.Especially for import business under EXW terms,if the overseas logistics is designated by the seller,it is very easy to lose the ownership of goods.

Reference of Real Practical Case

In February 2026,Mr.Yu,who is engaged in hardware tool import,needed to import 8 containers of manual tools from Japan,the trade term was FOB Osaka,and the payment term was 120-day usance L/C.He previously lost 170,000 RMB due to exchange rate fluctuation when issuing L/C on his own,and the goods were detained at Shanghai Port for 12 days due to document discrepancy,resulting in more than 90,000 RMB of port demurrage.

This time he entrusted us for the whole operation.We first completed HS Code classification in advance,confirmed that the batch of goods meets the tax reduction requirements of RCEP certificate of origin,confirmed the application specifications of the certificate of origin with the Japanese side in advance,to avoid failing to enjoy the tax reduction policy due to non-compliant certificate of origin; then combined with the shipping schedule and customs clearance efficiency of Shanghai Port,we set the payment term of the usance L/C as 150 days,reserving a 30-day buffer period; at the same time,we completed the forward exchange settlement in advance,locked the RMB to JPY exchange rate; finally,we arranged the pre-inspection of commodity inspection,and verified all documents 7 days in advance.

In the end,the goods completed customs clearance 3 days after arrival,no extra cost was incurred in the whole process,the exchange loss was controlled within 0.3%,and 87,000 RMB of tariff was saved through RCEP tax reduction.All subsequent import businesses of Mr.Yu are stably cooperated with us.
