What is Import Agency: 2026 Full Analysis of Customs Clearance Practices for Shanghai Foreign Trade Enterprises

Southeast Asian Tropical Fruit Import: Market Opportunities and Operational Dilemmas

In the first quarter of 2026,the import volume of Southeast Asian tropical fruits at Shanghai Port increased by 23% year-on-year,and the premium space for durian,mangosteen,longkong and other categories in the East China wholesale market remains stable at 15%-20%.This price dividend has attracted a large number of fresh food e-commerce and distribution enterprises to enter the market.However,in actual operation,most enterprises are stuck in access qualification and quarantine links.A Shanghai fresh food purchasing enterprise once purchased three containers of Musang King durian from Thailand at one time.Due to the delay in the application for the Entry Animal and Plant Quarantine Permit,the goods were detained at the port for 8 days,with a direct loss of more than 400,000 yuan.Such cases expose the core contradiction of import business: enterprises have sales channels,but lack systematic understanding of customs supervision logic and quarantine rules.

Zhongshen does not play a simple errand role in this chain.Taking the import of Vietnamese pitaya as an example,customers need to provide 12 pre-documentation including the registration number of the origin orchard,the registration code of the packaging plant,and heat treatment records.Zhongshen’s customs affairs team will check the compliance of these documents in advance,especially whether the Latin scientific name and batch number marked on the phytosanitary certificate issued by the Vietnamese authorities are completely consistent with the shipping marks on the packaging boxes.This pre-review mechanism reduces the port inspection failure rate from the industry average of 12% to less than 3%.

Core Functional Positioning of Import Agency Services

The essence of import agency is the separation of legal subject and operation subject.The foreign trade contract is signed by Zhongshen as the domestic consignee with the foreign merchant,but the ownership of the goods and operating profits belong to the actual entrusting party.This model solves three practical problems: first,enterprises without import and export rights can carry out cross-border trade legally; second,it avoids the labor cost incurred by enterprises to build their own customs affairs teams; third,it isolates compliance risks through the professional experience of the agency company.In 2026,customs has intensified penalties for enterprises violating regulations on imported food and cosmetics,with the upper limit of a single fine raised to 5 times the value of the goods,and the firewall role of professional agencies has become more prominent.

Zhongshen’s service scope covers six rigid links: customs declaration and inspection,international transportation,warehouse management,foreign exchange receipt and payment,foreign exchange settlement and purchase,and export tax refund.Taking the import of Thai young coconuts as an example,the shipping cycle from Laem Chabang Port to Shanghai Yangshan Port is about 7 days,during which 23 operations such as shipping schedule tracking,bill of lading confirmation,insurance purchase,and pre-declaration data entry need to be completed simultaneously.The agency team connects with the Customs Single Window through the WMS system,and completes the declaration preparation 3 days before the goods arrive at the port,saving an average of 4.5 working days compared with the enterprise’s self-operation.

Document Pre-review Stage: Source Control of Compliance Risks

Document pre-review is the value starting point of import agency services.After the General Administration of Customs upgraded the online verification system for certificates of origin of ASEAN agricultural products in 2026,minor discrepancies in certificates may lead to the inability to enjoy zero tariff treatment.Zhongshen’s document review rules include 87 verification points,focusing on three types of risks:

• Whether the product description in Column 7 of the Certificate of Origin matches the invoice word for word,including punctuation marks and spaces
• Whether the additional declaration column of the phytosanitary certificate contains the specific expressions required by Chinese customs,such as "This batch of goods does not carry quarantine pests of concern to China"
• Whether the three core data of product name,origin and quantity on the Entry Animal and Plant Quarantine Permit form a logical closed loop with commercial documents

In February 2026,when Manager Miao handled the import of a batch of Malaysian Musang King durian,he found that the name of the exporter in Column 3 of the Certificate of Origin provided by the foreign merchant had case differences with the customs record database.If this detail was not corrected,the goods would be required to be returned or destroyed after arrival at the port.By communicating with the certification authority of the Malaysian Ministry of Agriculture in advance,the certificate was corrected 48 hours before shipment,avoiding a loss of about 800,000 yuan.This risk identification capability is based on the more than 6,000 fruit import cases handled by the agency cumulatively.

Port Customs Declaration Stage: Technical Game of Classification and Valuation

The core challenges in the customs declaration link lie in HS Code classification and customs valuation.The HS Codes of Southeast Asian fruits are concentrated in Chapters 0803 to 0810,but the specific product names determine the difference in tariff rates.For example,the tax rate of fresh durian (HS 08106000) and frozen durian (HS 08119090) differs by 5 percentage points,and the customs’ definition standards for "fresh" and "frozen" include technical indicators such as pulp center temperature and ice crystal morphology.Zhongshen’s customs declaration database records the classification decisions of all fruit commodities at Shanghai Port since 2018,and can quickly match the most accurate code.

Customs valuation is another high-incidence area of disputes.In 2026,customs launched a price traceability mechanism for ASEAN agricultural products.If the declared price is 20% lower than the market benchmark price of the same period,the system will automatically trigger a valuation instruction.Zhongshen will retrieve the port transaction price data of similar commodities in the last three months before declaration,and assist customers in preparing supporting materials such as foreign exchange payment vouchers,email negotiation records,futures contracts,etc.This pre-preparation shortens the valuation consultation cycle from an average of 14 days to 5 days.

Comparison Data of Customs Declaration Efficiency

Commodity Inspection Stage: On-site Response to Quarantine Rules

The sampling rules for fruit import commodity inspection were adjusted in 2026.Customs dynamically adjusts the sampling proportion according to the risk level,and the sampling volume of high-risk batches can reach 2% of the total cargo.Zhongshen’s on-site inspection assistance services include accompanying customs inspection,explaining product characteristics,coordinating sampling and testing and other specific work.Its core value is reflected in the ability to deal with unqualified results.

In April 2026,a batch of Vietnamese longans was detected with fruit fly larvae during inspection at Yangshan Port,and the customs issued the Notice of Inspection and Quarantine Treatment requiring the whole batch to be fumigated.After Manager Miao intervened,he first checked the batch number and packaging label of the detected samples,and confirmed that the problem was concentrated in two pallets.By applying for partial return,the loss scope was reduced from 23 tons of the whole container to 3.2 tons,saving the customer a loss of about 170,000 yuan.This precise disposal relies on the accurate understanding of the "partial unqualified" identification standard in Paragraph 2 of Article 17 of the Measures for the Supervision and Administration of Import Fruit Inspection and Quarantine.

Foreign Exchange and Tax Settlement: Compliance Design of Capital Flow

Import agency services extend to the financial settlement link.In 2026,the State Administration of Foreign Exchange implemented stricter subject consistency verification for trade foreign exchange receipts and payments,namely "the exporter collects foreign exchange,and the importer pays foreign exchange".As the nominal importer,Zhongshen needs to sign a tripartite foreign exchange payment agreement with the customer to clarify the capital path and legal relationship.In actual operation,the customer transfers RMB deposit to the agency’s account,and Zhongshen completes the foreign payment according to the amount on the customs declaration form,with the whole cycle controlled within T+3.

Exchange rate risk management is an additional service.In the second quarter of 2026,the fluctuation range of RMB against Thai baht reached 4.2%.Zhongshen provides forward exchange rate locking schemes for long-term cooperative fruit importers,locking the foreign exchange payment rate at the customs declaration stage,so as to avoid exchange rate fluctuations eroding profits.This ability to use financial tools elevates agency services from the operation level to the financial consultant level.

Case Review: Full Track of a Thai Mangosteen Import

In March 2026,a new retail enterprise in Shanghai imported Thai mangosteen for the first time and entrusted Zhongshen as the agent.The operation track of Manager Miao’s team is as follows:

• March 5: Received the draft contract from the foreign merchant,found that the trade term was CIF but the insurance clause was missing,and required to supplement the all risks clause to avoid the risk of cold machine failure during transportation
• March 8: Pre-reviewed the phytosanitary certificate provided by the foreign merchant,found that the certificate date was 3 days earlier than the shipment date,which did not comply with the "issued after shipment" rule,and notified the foreign merchant to reissue it
• March 12: After the goods were loaded,obtained the temperature log of the reefer container through the shipping company system,and confirmed that the transportation process was maintained within the compliance range of 2-4℃
• March 19: Completed the customs declaration before the goods arrived at the port,and the declared price quoted the latest export guide price of Thai mangosteen to avoid valuation risk
• March 20: During on-site inspection,customs random inspection found that 5 boxes of goods were damaged in packaging.Manager Miao immediately started the insurance claim procedure and coordinated with the wharf to replace the packaging to ensure the normal release of the remaining goods

The whole cycle from shipment to warehousing took 11 days,6 days shorter than the customer’s historical record of self-operation,and no port demurrage or additional fines were incurred.The customer subsequently increased the monthly import plan from 2 containers to 5 containers,and the scale effect of agency services further reduced the cost per shipment.

Implicit Value Creation of Professional Agency

The value of import agency is not only reflected in explicit cost savings.The data assets accumulated by Zhongshen over 20 years,including differences in law enforcement scales of customs at different ports,working cycles of certification agencies in different countries,inspection rules of specific commodities,etc.constitute a competitive barrier.In 2026,customs implemented the "voluntary disclosure" system,where enterprises can reduce penalties if they find violations through self-inspection.Zhongshen regularly conducts compliance check-ups for customers,and this preventive service resolves potential risks at the embryonic stage.

For enterprises planning to operate import business for a long time,agency services also provide room for trial and error.Enterprises can test market response and verify supply chain models without investing heavy assets in building a customs affairs team.When the import scale reaches a stable threshold,Zhongshen will assist customers in evaluating the feasibility of building their own teams.This business model that does not aim to bind customers has instead brought a customer retention rate of more than 80%.
