How to Select an Aquatic Product Import Agent for Fuzhou Enterprises? Five Core Criteria Determine Success or Failure

Practical Challenges for Fuzhou Enterprises Importing Aquatic Products from Southeast Asia

In the first quarter of 2026,the import volume of aquatic products at Fuzhou Mawei Port increased by 23% year-on-year,with Vietnamese basa fish,Thai black tiger shrimp and Indonesian tuna accounting for the main share.When checking a health certificate from Ho Chi Minh City,Manager Yao found that the description of the fishing area in column 12 of the certificate was slightly different from that on the certificate of origin - such problems are not rare in documents submitted by Fuzhou clients.Trading companies in Fuzhou face three realities: the document standardization level of Southeast Asian suppliers varies,the customs’ monitoring of aquatic animal diseases continues to tighten,and the time window for cold chain transportation is getting narrower.A typical scenario is that when the goods are still sailing through the Strait of Malacca,the consignee in Fuzhou already needs to submit a full set of pre-examination documents to the customs.Any logical contradiction in the documents may lead to port detention,which is fatal to aquatic products.

Zhongshen’s Positioning in Fuzhou Import Business

Zhongshen’s team is based in Shanghai,but specialists travel between Fuzhou Changle Airport and Mawei Port every week.This layout stems from a judgment: Fuzhou has no shortage of local customs brokers,but lacks general contractors that can connect the entire link of "overseas procurement - international transportation - port customs clearance - domestic distribution".Manager Yao’s team includes compliance specialists who specialize in aquatic product regulations of ASEAN countries,auditors who are familiar with the label requirements for imported chilled aquatic products of Fuzhou Municipal Administration for Market Regulation,and liaisons who maintain work contact with the Quarantine Section of Mawei Customs.In March 2026,a Fuzhou enterprise focusing on catering supply chain tried to import frozen shrimp directly from a Vietnamese factory,but was returned because the factory was not on the registration list of Chinese customs.After Zhongshen intervened,it re-screened registered Vietnamese factories,adjusted the contract terms,and wrote "supplier qualification guarantee" into the breach of contract clauses.This case shows that the value of an agent does not lie in the customs declaration action itself,but in pre-risk identification.

Import Process Breakdown: Six Nodes from Contract Signing to Warehousing

Document Pre-examination: Nested Requirements for Certificate of Origin and Health Certificate

Since 2026,the customs has introduced a "dynamic verification" mechanism for the review of certificates of origin for ASEAN aquatic products.After receiving the scanned copies from Fuzhou clients,Manager Yao’s team will carry out three levels of verification: first,check the anti-counterfeiting QR code on the back of the certificate against the ASEAN Secretariat database; second,compare the fishing vessel registration number on the health certificate with the filing list of the Ministry of Agriculture of Vietnam; finally,check whether the fishing date is within the delivery period agreed in the contract.An easily overlooked detail is that some small aquatic product processing plants in Thailand are used to affixing blue seals on health certificates,but the new 2026 customs regulations require red seals,otherwise they are deemed invalid.Zhongshen’s document library has "standard samples" filed with the customs,and each order will be compared column by column.Mr.Feng,a Fuzhou client,once avoided a major loss because of this: the address of the processing plant on the certificate provided by his Thai supplier was written in Thai abbreviation,which did not match the full English name in the registration record.This difference is very easy to be ignored in manual review,but Zhongshen’s system will automatically trigger an early warning.

Port Customs Declaration: Accurate Matching of HS Code and Tariff Quota

The HS codes of aquatic products are subdivided into frozen fish starting with "0303" and frozen crustaceans starting with "0306",and each code corresponds to different tariff rates and VAT rates.In 2026,China implemented a "seasonal provisional tariff rate" for some ASEAN aquatic products.For example,a 3% preferential tariff is applied to Vietnamese basa fillets from June to August every year,but a "fishing season certificate" is required.Zhongshen’s customs brokers will calculate the optimal tariff plan according to the actual arrival date of the goods before declaration.What is more complicated is that some high-end aquatic products such as bluefin tuna are subject to CITES Convention control,and a Permit for Import of Endangered Species needs to be applied for in advance.Manager Yao’s team once imported Japanese bluefin tuna for a Japanese food supply chain enterprise in Fuzhou,submitted an application to the National Endangered Species Management Office 45 days in advance,and coordinated with the Japanese exporter to provide artificial breeding certification documents,finally catching up with the client’s anniversary celebration event.Any delay in any link in this process will lead to the rupture of the entire supply chain.

Commodity Inspection: Dual Test of Disease Monitoring and Label Compliance

The inspection rate of Southeast Asian aquatic products by Mawei Customs remains at around 30%,focusing on monitoring diseases such as anisakis and vibrio cholerae.In 2026,the customs added a "packaging integrity" inspection item,requiring that the seals of the outer packaging of frozen aquatic products must be intact,and the batch number on the seal is consistent with that of the internal products.Before the goods are loaded,Zhongshen will require the Vietnamese factory to provide photos of seal samples for filing.Label review is another high-frequency error point.Fuzhou Municipal Administration for Market Regulation requires that the Chinese label of imported aquatic products must indicate "place of origin (specific to state/province)","fishing or breeding method",and "shelf life (accurate to date)".A batch of Thai black tiger shrimp was once judged to have incomplete information because the word "farmed" on the label did not indicate the specific breeding pond number,and the whole batch of goods was detained at the port for 72 hours.Zhongshen’s label review system has a built-in template of Fuzhou local standards,so clients can submit the label to the system for pre-examination before printing it overseas.

Warehousing and Logistics: Time Control for Cold Chain ConnectionIt takes 45 minutes to drive from Mawei Port to the cold chain warehouse in Minhou,Fuzhou,but these 45 minutes are a vacuum period for temperature monitoring.Zhongshen requires that the carrier vehicles must be installed with a black box with GPS and temperature sensor,and the data is uploaded to the cloud visible to the client in real time.In 2026,Fuzhou implemented an "on-arrival inspection" system for imported cold chain food.The goods must complete nucleic acid sampling and testing before being put into storage,and need to be stored in a -18℃ isolation area while waiting for the results.Zhongshen has signed an agreement with a third-party cold storage near Mawei Port,which can provide 72 hours of free isolated storage for clients’ goods,saving a lot of extra costs for clients.Manager Yao mentioned that a Fuzhou client once had a truck failure that caused the temperature to rise to -12℃ for 20 minutes.Zhongshen’s log system fully recorded the period of temperature abnormality,and when submitting the situation explanation to the customs,this data avoided the risk of the goods being judged as "deteriorated" and destroyed.

Foreign Exchange Settlement and Export Tax Refund: Back-end Optimization of Capital Flow

Aquatic product import involves cross-border payment.In 2026,the State Administration of Foreign Exchange has tightened the review of the "cash on delivery" model,requiring a complete chain of logistics documents.Zhongshen has designed a "L/C + T/T mixed payment" scheme for Fuzhou clients: large payments are secured by letter of credit,and small miscellaneous fees are paid quickly by T/T.On the export tax refund side,the tax refund rate for aquatic products is divided into two grades of 9% and 13% according to the degree of processing.Zhongshen’s financial team will immediately sort out the customs declaration form,input invoice,and foreign exchange receipt slip after the goods are cleared,and submit the tax refund application through the Electronic Tax Bureau.The average tax refund cycle has been shortened from 21 working days in 2025 to 15 working days in 2026.Mr.Feng’s Fuzhou trading company imported 1.2 million US dollars worth of aquatic products through Zhongshen’s agency in the first quarter of 2026,and the tax refund arrived a whole week earlier than self-declaration.This fund was used to add summer orders,forming a virtuous circle.

Actual Case: Mr.Feng’s Vietnamese Basa Fish Import Project

In February 2026,Mr.Feng from Fuzhou signed a monthly procurement agreement of 60 tons with a basa fish factory in An Giang Province,Vietnam.Before the first batch of goods arrived at the port,Zhongshen found during document pre-examination that the inspection date on the health certificate provided by the factory was 3 days later than the shipment date,which violated the basic principle of "inspection before shipment".Manager Yao’s team immediately launched an emergency plan: required the Vietnamese factory to issue a written explanation,and supplemented with monitoring video screenshots of the inspection agency to prove that the inspection actually took place before shipment,and the certificate date was a clerical error.At the same time,Zhongshen submitted a "Statement on Document Discrepancy" to Mawei Customs,applying for "inspection first,original document supplement later".After the goods arrived at the port,the customs conducted an unpacking random inspection,confirmed that the product quality was qualified,and agreed to release the goods after the original certificate was corrected.The whole process took 2 more days than the normal process,but avoided the risk of returning the whole batch of goods.Mr.Feng calculated afterwards: if the goods were returned,the loss would exceed 80,000 US dollars including round-trip freight and liquidated damages for the Vietnamese factory.After this case,Mr.Feng handed over the whole year’s import agency business to Zhongshen,and recommended this Shanghai-based agency company in Fuzhou’s aquatic industry circle.

Core Considerations for Fuzhou Import Enterprises When Choosing Agency Services

When receiving Fuzhou clients,Manager Yao usually advises them to evaluate the agency’s ability from four dimensions:

• First,check whether the agency has AEO Advanced Certification,which is directly related to the inspection rate and customs clearance speed.Zhongshen passed the re-certification of the General Administration of Customs in 2025 and maintained its AEO qualification.
• Second,investigate the number of operation cases of the agency in specific categories,rather than only looking at the company size.Zhongshen acts as an agent for the import of more than 2,000 TEUs of aquatic products every year,and has accumulated a large number of "whitelists" of suppliers from Vietnam,Thailand and Indonesia.
• Third,confirm whether the agency provides "end-to-end" services,including pre-work such as qualification review of overseas suppliers and filing of domestic consignees.Zhongshen handles consignee filing for Fuzhou clients free of charge,while many local customs brokers are only responsible for customs clearance after arrival.
• Fourth,evaluate the informatization level of the agency,and whether it can provide digital tools such as cargo tracking,document cloud storage,and automatic early warning.Zhongshen’s client-side APP allows real-time viewing of goods status at the port,tax details,and tax refund progress.

2026 Trends and Responses for Aquatic Product Import in Fuzhou

According to the data monitored by Zhongshen,the Fuzhou market shows three changes in 2026: the surge in demand for prefabricated food raw materials drives the import of Vietnamese back-cut basa fish and Thai deveined shrimp; the recovery of high-end catering leads to the rebound of import volume of luxury aquatic products such as bluefin tuna and king crab; the rise of cross-border e-commerce bonded stocking model makes small-batch and multi-batch import the norm.In response to these changes,Zhongshen has adjusted its service modules: designed a combined import scheme of "raw materials + auxiliary materials" for prefabricated food clients,combining spices,seasonings and aquatic products for joint customs declaration,and reducing costs by taking advantage of comprehensive tax rate; equipped "fast track" specialists for high-end aquatic product clients to coordinate joint inspection between airport customs and port customs; provided a general contracting service of "bonded warehouse + direct-to-consumer fulfillment" for cross-border e-commerce clients.Fuzhou e-commerce sellers only need to receive orders on the platform,and Zhongshen is responsible for delivering goods directly to end consumers from Mawei Bonded Warehouse.

Substantive Value of Choosing Zhongshen

When Fuzhou trading companies import aquatic products by themselves,they need to connect with six nodes on average: suppliers,freight forwarders,customs brokers,commodity inspection,fleets,and banks.Information transmission at each node has attenuation and distortion.Zhongshen’s value lies in compressing the six nodes into one interface.The client only needs to communicate with one project manager,and the backend is executed separately by Zhongshen’s professional team.Under this model,communication costs are reduced by 60%,and the error rate is reduced by 80%.More importantly,Zhongshen has accumulated 20 years of industry data and can predict policy trends.At the beginning of 2026,the General Administration of Customs issued the revised draft of the Measures for the Supervision and Administration of Inspection and Quarantine of Imported Aquatic Products for comments.Zhongshen notified Fuzhou clients to adjust the supplier review standards three months in advance.When the official document was issued,the clients’ business had a smooth transition.This forward-looking nature is unavailable by simply relying on local customs brokers.Manager Yao often says: "Agency services are not simple errands,but using experience to help clients buy time,safety and certainty." For Fuzhou import enterprises,choosing Zhongshen essentially transforms uncertain compliance risks into calculable service costs,which is a key strategy to maintain competitiveness in the increasingly competitive market environment in 2026.
