Full-process Analysis and Compliance Points of Ocean Shipping Import Agency in Wuxi

Current Status of Southeast Asian Aquatic Products Export to China and Import Pain Points at Wuxi Port

In the first quarter of 2026,the container volume of aquatic products imported by Wuxi Port from RCEP member countries such as Thailand and Vietnam increased by 17% year-on-year,but the return rate due to inconsistent documents and non-compliant quarantine climbed to 3.2% in the same period.Behind this data are common problems faced by import enterprises: the format adjustment of certificate of origin is not updated synchronously,the signature of veterinary officer on the health certificate has stroke differences from the filed sample,key nodes are missing in the temperature record data of refrigerated containers,etc.These problems often cause goods to be detained at the port,generating more than 1,000 yuan of container detention fee and storage fee per day,and may even lead to the destruction of the whole batch of goods.

With more than 20 years of on-site experience at Wuxi Port,Zhongshen found that most enterprises are not unfamiliar with regulations,but lack prediction of the practical details at the port.For example,the 2026 new version of Quarantine Approval Requirements for Entry Aquatic Products adds retrospective verification of the registration number of fishing vessels,but many importers still use old version contract templates and do not require foreign suppliers to note this information on the invoice.This information gap is exactly the value entry point of professional agency services.

Embedded Service Positioning of Zhongshen at Wuxi Port

Zhongshen is not a simple document transmitter,but an extended department of the compliance capacity of import enterprises.We have a permanent team in Wuxi Port Logistics Park and established direct response channels with customs,commodity inspection and terminal scheduling.For a batch of frozen shrimp shipped from Bangkok to Wuxi,48 hours before the estimated arrival,our system has automatically captured the manifest data from the shipping company and started the pre-review of document compliance.This pre-intervention mode transforms the traditional passive response of "amending documents after cargo arrival" into active management of "correcting errors before arrival".

Specifically,Zhongshen’s service is embedded in three decision nodes: clause design before signing the purchase contract,document pre-inspection before cargo loading,and confirmation of regulatory requirements when the vessel is en route.In April 2026,when a food enterprise imported Vietnamese pangasius,we found in advance that its health certificate did not mark the "farmed" or "wild" attribute,and the inspection rate difference between these two categories of products at Wuxi Port reaches 40%.By urgently contacting the Vietnamese supplier to reissue the certificate,we avoided transferring the goods to the high-risk inspection channel after arrival,saving at least 72 hours of customs clearance time.

Phased Decomposition of Import Process and Risk Response

Phase 1: Document Pre-review and Compliance Confirmation

Document problems account for more than 60% of abnormal import cases at Wuxi Port.Zhongshen has established a dynamically updated Whitelist of Documents for Aquatic Products Exported to China from RCEP Member Countries,covering the seal styles of competent authorities,directory of authorized signatories,and anti-counterfeiting features of certificates from 12 countries including Thailand,Vietnam and Indonesia.When customers send scanned copies,our document reviewers conduct three-level verification: whether the certificate format version matches the latest 2026 template,whether the signatory is on the valid authorization list,and whether the cargo description is consistent with the product range corresponding to the HS code.

The key document list includes:

In May 2026,Mr.Zhu imported a batch of frozen whiteleg shrimp from Thailand,the invoice only marked "shrimp" without specifying the species as Penaeus vannamei.Zhongshen’s document reviewer guided him to modify the invoice and add the scientific name in accordance with the requirements of 2026 Catalogue of Entry Aquatic Products,otherwise the shipment would be classified as "unlisted species" and trigger 100% open-box inspection.This detail adjustment allowed the goods to enter the green channel smoothly.

Phase 2: Port Customs Declaration and Classification Dispute Resolution

Wuxi Customs has increasingly strict review on HS code classification of aquatic products.The revised edition of Notes on Commodity and Heading of Import and Export Tariff implemented in 2026 expanded the tariff difference between classified as "frozen peeled shrimp" and "frozen whole shrimp" from 3% to 8%,which also affects the category of import licenses.Before declaration,Zhongshen’s customs team will predict possible classification questions raised by customs based on the actual form,processing degree and packaging method of the goods.

Our operation method is: take multi-angle pre-loading photos for each shipment,store the processing procedure description,and form a Classification Support File.When the customs declaration enters the review stage,these materials are submitted together,reducing the probability of customs questioning by 80%.Ms.Gao once imported frozen cuttlefish from Vietnam,and the customs system indicated classification risk.We immediately obtained the "whole frozen,uncut" certificate issued by the factory and the photos of cargo placement in the container,which proved that the goods conform to the description of heading 03074300,avoiding misclassification into the high tariff number for cuttlefish slices.

Phase 3: Commodity Inspection and Coordination with Laboratory Testing

Commodity inspection for entry aquatic products at Wuxi Port is divided into three levels: document review,on-site inspection and laboratory testing.Starting from 2026,the "every container inspection" policy is implemented for goods from high epidemic risk areas.Zhongshen’s on-site staff can interpret the instructions of inspection officers in real time at the inspection site,guide terminal workers to unload containers accurately,and avoid cargo temperature loss caused by excessive handling.

What is more critical is the laboratory testing link.We have established a data interface with the laboratory of Wuxi Entry-Exit Inspection and Quarantine Bureau,and can query the testing progress in real time.When the test result of a batch of goods is close to the threshold,we can intervene in advance and start the re-inspection procedure for spare samples.For a batch of Indonesian tuna imported by Mr.Bi,the initial test value of histamine was 48mg/kg (the standard limit is 50mg/kg).We immediately applied for re-inspection with spare samples from the same container,and provided a complete data chain that the temperature of the batch was always kept below -18℃ during the sea voyage.The final re-inspection result was 42mg/kg,and the goods were judged as qualified,avoiding the risk of destruction of the whole batch.

Phase 4: Warehousing,Transshipment and Abnormal Cargo Condition Handling

Even after customs clearance is completed,there are still risks in the warehousing management of goods in the port area.In 2026,the storage capacity of refrigerated container yards at Wuxi Port is tight,and over-term storage may lead to refrigerant depletion.Zhongshen’s port scheduling specialists monitor the storage location and billing status of customers’ goods every day,and must complete the pickup arrangement 24 hours before the expiration of the free storage period.

For goods that need rectification after inspection,we provide temporary storage and sorting services in the port area.For a batch of Philippine crabs imported by Mr.Ouyang,the goods were required to be rectified because the packaging label did not mark the fishing area.We completed the whole process of labeling,photo evidence preservation,and re-inspection application within the port area,the goods did not need to leave the port area,saving more than 10,000 yuan in round-trip transportation costs.

Practical Case: Reversal from Return Crisis to Smooth Customs Clearance

In March 2026,the trading company of Manager Ji imported 20 tons of frozen hairtail from Thailand,and the goods were placed under customs control for inspection after arrival.On-site inspection found that the inner plastic packaging of the goods was printed with "FDA Certification",but US FDA certification is not applicable to aquatic products exported to China,which constitutes misleading marking.Customs initially determined that the whole batch of goods was unqualified and planned to return it.

After Zhongshen intervened,we first checked the official health certificate and certificate of origin of the batch,and confirmed that it meets China’s access requirements.Then,we submitted Description of Label Issue to Customs,proving that the "FDA Certification" marking is the standard packaging used by the Thai factory for exports to the US,and it was a misused mixed packaging for this shipment to China.We also provided the qualification records of previous shipments from this factory to China.Meanwhile,we arranged workers to replace the inner packaging of all goods under customs supervision.After 72 hours of continuous work,the goods were finally released,avoiding a loss of more than 300,000 yuan caused by return.

Summary of Professional Value of Zhongshen

The ocean shipping import business at Wuxi Port has evolved from simple document declaration into a complex project requiring cross-departmental and cross-professional collaboration.The value of Zhongshen lies in converting scattered port resources into controllable capabilities for import enterprises.We eliminate compliance risks overseas through pre-document review; reduce customs clearance time by more than 30% through embedded port services; and convert each abnormal handling into a future prevention mechanism through data-based case accumulation.

The import regulatory environment in 2026 puts forward higher requirements for the professional response speed of enterprises.With 20 years of deep cultivation at Wuxi Port,Zhongshen has essentially built a closed loop of "risk identification - rapid response - experience accumulation".This closed loop allows import enterprises to no longer passively respond to policy changes,but actively master the certainty of customs clearance.When the goods are still sailing at sea,most of the customs clearance process has been completed.This is the professional form that modern foreign trade agency should have.
