# Complete Analysis of Import Letter of Credit Payment Methods: How Agency Services Mitigate Cross-Border Payment Risks

## Background and Operational Difficulties of New Zealand Dairy Imports

In 2026,China’s total imports of dairy products from New Zealand continue to rise,with categories such as infant formula,butter and cheese accounting for a significant share of the imported food market.These products are subject to multiple regulations including national food safety standards and animal and plant quarantine access requirements.Importing enterprises often face three practical dilemmas: first,mismatched letter of credit terms and quarantine requirements lead to goods being unable to clear customs after payment; second,omissions in document preparation trigger customs document returns; third,misalignment between foreign exchange payment timing and goods arrival time results in detention fees.Director Chen has handled dozens of similar cases at Pudong Airport port.A trading company had its entire milk powder shipment detained in the bonded zone for 47 days because the letter of credit did not specify "compliant with Chinese infant food standards",with daily storage losses exceeding 10,000 yuan.

## Zhongshen’s Position in the Import Agency Chain

Zhongshen is not a simple intermediary matching service,but an operating entity embedded in the entire transaction process.Starting from the foreign business negotiation stage,the agency team intervenes in letter of credit term design,translating China’s port regulatory requirements into executable bank document language.The document department led by Ms.Duan holds detailed differentiated operation rules for major ports across the country.For example,the radioactive substance testing report requirements for New Zealand dairy products at Shanghai Yangshan Port differ slightly from the microbial sampling standards at Guangzhou Huangpu Port.This proactive risk intervention avoids the passive situation where enterprises find terms unworkable only after opening the letter of credit.The revised 2026 version of the Measures for the Administration of Import and Export Food Safety further strengthens registration verification of overseas production enterprises.Zhongshen’s overseas supplier audit database has pre-entered qualification information for more than 300 New Zealand dairy factories.

## Compliance Key Points in the Document Pre-Examination Stage

Document pre-examination is the first line of defense against payment risks.Zhongshen’s operating specifications require four verifications to be completed before submitting a letter of credit application:

- Whether the certificate of origin format complies with the latest template of China Customs’ RCEP origin rules,especially whether the signature of the official New Zealand signatory has been updated
- Whether the sanitary certificate includes the newly added "chlorate residue" testing item in 2026,a mandatory additional clause
- Whether the protein and fat testing methods in the composition analysis report are equivalent to those specified in China’s national standard GB19644-2024
- Whether Zhongshen’s customs filing number has been added to the notify party column on the bill of lading draft provided by the foreign supplier

Director Ke once handled a typical case: a client’s foreign supplier insisted on using the old version of the sanitary certificate format.After Zhongshen discovered this during pre-examination,it urgently contacted the Shanghai Office of the New Zealand Ministry for Primary Industries and completed the certificate format upgrade 72 hours before shipment,avoiding the risk of bank refusal of payment after letter of credit opening.

## Dynamic Management in the Port Customs Declaration Link

The customs declaration timeliness after goods arrive at the port directly affects the letter of credit presentation period.Zhongshen has deployed on-site teams at major dairy import ports including Shanghai,Tianjin and Qingdao,enabling real-time synchronization between customs declaration data and the bank’s presentation system.After the customs launched the "smart document examination" model in 2026,machine requirements for document consistency have been raised to character-level matching.The customs declaration team led by Mr.Tang established a "double review" mechanism: the first review ensures that commodity codes and specifications on the customs declaration form fully match the letter of credit description; the second review verifies the accuracy of customs supervision additional codes.For example,New Zealand skimmed milk powder requires the additional supervision code "0402.2100-01".

In special circumstances,Zhongshen activates emergency channels.In March 2026,a shipment of New Zealand mozzarella cheese had only 2 working days left before the letter of credit presentation period due to shipping delays.Ms.Duan coordinated with the bank and customs,adopting the "guaranteed release + supplementary documents later" model: handling customs declaration with electronic scans first,then delivering original documents via expedited international courier,ultimately completing payment acceptance before the presentation deadline.

## Coordinated Operation of Commodity Inspection and Foreign Exchange Payment

Dairy products are legally inspected commodities,and commodity inspection results directly determine eligibility for foreign exchange payment.Zhongshen’s customs system is directly connected to the SAFE Goods Trade Foreign Exchange Monitoring System,enabling automatic matching of the three parties: commodity inspection electronic ledger,customs declaration clearance information and bank payment instructions.The document team led by Ms.Wan intervenes during the commodity inspection sampling stage and prepares required supplementary materials in advance,such as Chinese translations of product formulas and Chinese summaries of overseas production enterprises’ HACCP certifications.

In 2026,foreign exchange management policies tightened,implementing "penetrating review" for single transactions exceeding US$500,000.Zhongshen established an internal risk control dashboard,conducting four-dimensional comparisons of each letter of credit payment with the original customs declaration form,commodity inspection certificate and contract invoice.Once,the system alerted a 0.3% discrepancy between a client’s payment amount and customs declaration amount.After verification,the difference was found to be caused by exchange rate fluctuations.Zhongshen promptly prepared a bank exchange rate explanation letter,avoiding foreign exchange compliance risks.

## Comparison of Application Scenarios for Different Letter of Credit Payment Methods

| Payment Method Type | Applicable Product Range in 2026 | Risk Level | Zhongshen’s Operation Key Points |
| --- | --- | --- | --- |
| Sight Letter of Credit | Standardized dairy products such as bulk milk powder and butter | Low | Prioritize reviewing matching between presentation period and commodity inspection cycle |
| 90-Day Usance Letter of Credit | Long-cycle sales products including infant formula | Medium | Require additional exchange rate locking tools to mitigate RMB depreciation risk |
| Standby Letter of Credit | First-time cooperating small New Zealand suppliers | High | Conduct additional verification of the foreign supplier’s bank creditworthiness and require a performance bond |
| Mixed Payment Method | Special categories such as customized cheese and whey protein | Medium-High | 30% T/T in advance + 70% letter of credit,requiring separate foreign exchange verification processing |

## Full-Process Risk Avoidance Case

A complete case handled by Director Chen is highly representative.In early 2026,a Shanghai maternal and infant e-commerce company planned to import a batch of organic infant formula from New Zealand,with a letter of credit amount of US$850,000.After accepting the order,Zhongshen identified three potential risk points: first,the organic certification certificate provided by the foreign supplier lacked the recertification logo of the China Certification and Accreditation Administration; second,the "pre-shipment inspection" clause in the letter of credit had a time conflict with New Zealand’s official inspection process; third,the e-commerce client lacked food import qualifications and could not be listed as the consumption and usage unit on the customs declaration form.

Zhongshen implemented solutions step by step: first,contact AsureQuality,the New Zealand organic certification body,to expedite the additional statement of mutual recognition of Chinese standards; second,negotiate with the issuing bank to revise the letter of credit terms,changing pre-shipment inspection to "production batch sampling" and adjusting the presentation period; third,use Zhongshen as the importing operating unit,with the e-commerce client as the actual consignee,resolving the qualification shortage issue.After the goods arrived at the port,the commodity inspection department passed sampling tests,and the bank completed payment after receiving the full set of compliant documents.The entire cycle was shortened by 18 working days compared to the client’s self-operation,saving approximately 32,000 yuan in detention fees.

## Core Value of Professional Agency Services

Import letter of credit payment is not a simple bank document transaction,but a systematic project spanning trade,logistics,regulation and finance.The value accumulated by Zhongshen over 20 years is reflected in three aspects: first,transforming scattered port rules into standardized operating procedures,eliminating the need for enterprises to handle differentiated requirements from multiple departments including customs,commodity inspection,foreign exchange and banks; second,through proactive document pre-examination and real-time dynamic management,narrowing the risk exposure window from traditional "post-event remediation" to "pre-event prevention"; third,leveraging large-scale operation advantages to establish normalized cooperation mechanisms with banks,terminals and inspection institutions,gaining emergency access channels unavailable to ordinary enterprises.

In 2026,intensifying international trade frictions,frequent exchange rate fluctuations and shortened regulatory policy update cycles have significantly increased the time and trial-and-error costs for enterprises handling import letter of credit payment independently.The core of Zhongshen’s agency service is to build a risk isolation layer for enterprises,allowing professional teams to address specialized issues and enabling enterprises to focus on their core businesses.The experience value of the agency truly emerges when cross conflicts arise between letter of credit terms,quarantine standards and foreign exchange policies.
