Key Operation Points and Risk Mitigation for International Letter of Credit Services for Importers

Importing Tropical Fruits from Southeast Asia: Documentation and Timing Game Behind Letter of Credit

For fresh produce importers in East China,purchasing tropical fruits such as durians and mangosteens from Thailand,Vietnam and other regions has been a steadily growing business in recent years.However,the characteristics of high product value and extremely short shelf life have exacerbated the conflict between payment security and customs clearance speed.Importers need to provide overseas suppliers with a solid payment guarantee to lock in high-quality supply and favorable prices,while also ensuring that goods can clear customs and be delivered to the market as quickly as possible after arrival.The international letter of credit theoretically provides this balance,but in actual operation,differences in document formats and terminology habits of exporters from Southeast Asian countries,China Customs’ constantly adjusted quarantine access lists and quarantine requirements for fresh fruits,and the strict standards of bank document examination form a triangle full of uncertainty.

Many enterprises,when operating on their own,often face bank rejection due to a minor discrepancy in documents—for example,the weight unit on the packing list does not match the requirements of the letter of credit,or the issuing authority of the phytosanitary certificate is not included in China Customs’ latest list—resulting in goods being detained at the port with huge container demurrage charges and quality losses.More troublesome is that some Southeast Asian suppliers are unfamiliar with the letter of credit process,and their repeatedly revised submitted documents cause them to miss the most valuable sales window.

The core role of Zhongshen’s import agency services in such businesses is to act as a professional "document and process control center" for enterprises.We do not simply apply for letter of credit issuance to banks on behalf of enterprises,but integrate the drafting of letter of credit terms,pre-review and judgment of full-process documents,filing of domestic import qualifications,and coordination of port customs quarantine into a controllable closed-loop system.

Phase 1: Letter of Credit Issuance and Document Pre-review — Setting Secure Game Rules

When contacting a client Mr.Xiao who planned to import a full container of Monthong durians from Thailand for the first time,Senior Director Gao from Zhongshen first reviewed the "List of Fresh Fruit Types and Exporting Countries/Regions Allowed for Import" updated by the General Administration of Customs in 2025 to confirm the access status of Thai durians and the specified quarantine requirements.This became the basis for drafting the letter of credit terms.

The setting of letter of credit terms directly affects the smoothness of all subsequent links.Our approach is to convert mandatory domestic import requirements into document conditions that the beneficiary (exporter) under the letter of credit must submit.For example:

• Require the submission of a phytosanitary certificate issued by a specific institution under Thailand’s Ministry of Agriculture,and the certificate must indicate the registration numbers of the orchard and packaging factory,which corresponds one-to-one with the quarantine access requirements of China Customs.
• For the perishable nature of fruits,set a latest shipment date and reasonably link it with the validity period of the letter of credit to avoid goods arriving late while the letter of credit expires.
• Require the sea bill of lading to indicate "refrigerated temperature maintained at XX degrees Celsius",and use it as one of the negotiation documents to restrict the goods storage conditions from the transportation link.

Prior to issuing the letter of credit,we will clearly communicate the key document preparation requirements to overseas suppliers and provide sample documents in both Chinese and English to reduce subsequent amendments caused by their misunderstanding.This proactive communication can avoid at least 50% of potential document discrepancies.

Phase 2: Arrival of Goods and Customs Declaration and Inspection — Compliance Clearance in a Race Against Time

For the import of fresh fruits such as durians,commodity inspection (now called "customs inspection and quarantine") is the core,most time-consuming and risk-prone link.Prior to the arrival of goods at the port,Zhongshen’s customs declaration team has completed the preparation work for import declaration in advance.This includes not only basic documents such as packing lists,invoices,contracts and bills of lading,but more importantly:

At this stage,we act as the "on-site coordinator" for enterprises.For example,last year,a batch of pitayas imported from Vietnam arrived at Shanghai Port on a weekend due to delayed berthing of the vessel.Mr.Xiao was worried that the quarantine department would be off duty,and each extra day of delay would increase the risk of fruit rot.Zhongshen’s customs personnel immediately initiated emergency communication,coordinated with customs to schedule an inspection,completed the inspection procedures on Sunday,and the goods were released and delivered on Monday,maximizing the freshness of the fruits.

Phase 3: Warehousing,Distribution and Settlement Support — Closed-loop Management and Risk Isolation

After the goods are cleared and released,for fresh produce,the connection between warehousing and distribution must be seamless.The cold chain warehouses partnered with Zhongshen can provide constant-temperature temporary storage,sorting and packaging services,and quickly deliver to various wholesale markets or supermarkets in East China according to client instructions.In terms of financial settlement,our role is equally critical.

When the bank receives the full set of letter of credit documents sent from overseas,Zhongshen’s document specialists will conduct a bank-level pre-examination.On one occasion,during Mr.Xiao’s durian import business,the bank’s preliminary review found a slight discrepancy between the trade terms on the invoice and the letter of credit,which could constitute a discrepancy.We immediately checked the original contract and correspondence emails,and found that it was a typo by the supplier.We then instructed the supplier to issue a correction certificate and submit it within the time stipulated by the bank,ensuring a smooth payment process and avoiding payment refusal disputes caused by minor issues.

In addition,we act as an agent to complete foreign exchange purchase and payment to overseas suppliers,and also handle subsequent matters such as import value-added tax deduction for the enterprise,standardizing the capital flow and document flow,and isolating the risks that enterprises face directly from foreign exchange fluctuations and payment compliance.

Case of Resolving a Document Discrepancy Dispute

At the end of 2025,a client Mr.Jiang imported a batch of frozen seafood from Malaysia.The letter of credit required a "full vessel disinfection certificate",but the certificate submitted by the supplier was named "ship hygiene certificate".The bank identified this as a discrepancy and planned to refuse payment.At this time,the goods were already at sea.If payment was blocked,it would affect the pickup of goods and generate a large amount of port demurrage fees.

Upon receiving the bank’s notice,Senior Director Gao from Zhongshen did not wait passively.He immediately reviewed the relevant regulations of the International Maritime Organization (IMO) and China Customs’ hygiene requirements for ships carrying imported food,and found that in the context of this business,the substantive content and purpose of the two certificates were exactly the same,only the name expressions differed due to different national habits.We assisted Mr.Jiang in quickly collecting materials such as IMO clause explanations and industry practice proofs,and submitted a detailed technical explanation letter to the issuing bank.After well-founded communication,the bank accepted the explanation and finally accepted and paid externally.This process not only avoided payment disputes,but also saved the client potential tens of thousands of yuan in port demurrage costs and communication costs.

Value of Professional Agency: Efficiency Improvement and Systematic Risk Reduction

The value of import agency for letter of credit issuance is far more than just "running errands" or "filling out forms on behalf of others".Based on the 20 years of accumulated industry database (including document samples from various countries,customs regulation updates,and quarantine standard updates) and port practice experience,Zhongshen has transformed the seemingly standardized but actually ever-changing letter of credit process into predictable and manageable modules.For enterprises,this means:

The procurement team can focus more on quality control and marketing,while handing over complex professional matters such as international payment,cross-border logistics and government regulatory compliance to us for integrated processing.Through our proactive intervention and full-process control,we minimize the document error rate,ensuring that the letter of credit payment tool truly becomes a weapon to ensure transaction safety rather than a source of risk.Against the backdrop of the increasingly complex 2026 international trade environment and more precise customs and quarantine supervision,this systematic risk control and efficiency improvement are directly related to the core profits and market competitiveness of import enterprises.
