# Tianjin Import Trade Agent Selection Criteria: 2026 Practical Guide and Pitfall Avoidance Tips

## Import of Frozen Aquatic Products from Southeast Asia to Tianjin: Current Status and Operational Challenges

In 2026,the throughput of cold-chain cargo at Tianjin Port continues to rise,with frozen aquatic products such as shrimp,basa fish,and cuttlefish from Southeast Asia becoming hot import items.These goods have extremely high timeliness requirements,and the entire temperature from factory shipment to storage in Tianjin Port’s refrigerated containers must be maintained below minus 18 degrees Celsius.In actual operations,enterprises often encounter three types of difficult problems: First,dynamic adjustments to the access catalog: the imported products of a certain country’s farmed shrimp may be suddenly suspended due to disease early warning.Second,strict document details: the color of the fish oil seal on the Vietnamese official sanitary certificate and the specific format of Thailand’s certificate of origin may become reasons for return of documents.Third,fluctuating port inspection rates: Tianjin Customs’ sampling rate for microorganisms and heavy metals of aquatic products from ASEAN countries rose by 15 percentage points year-on-year in the first quarter of 2026.

These variables cause many first-time importers to have their cargo detained at the port,incurring thousands of yuan in daily container demurrage fees.A more hidden risk is that some enterprises arrange shipment before the quarantine license is completed,and the goods can only be returned or destroyed upon arrival.The storage capacity of Tianjin Port’s cold-chain supervision warehouse remains above 85% all year round,and the waiting time for scheduled inspection directly affects the freshness of the goods and their market price.

## Core Role of Zhongshen in Tianjin Port Import Agency Services

The Zhongshen team is familiar with the operation habits of each operation area of Tianjin Port.The Dongjiang Port Area is suitable for large-volume full-container cargo,while the Beijiang Port Area is more flexible for LCL cold-chain inspection.These details directly affect the design of customs clearance plans.The core value of agency services lies in translating fragmented regulatory requirements into executable operation lists.When a client plans to import hairtail from Indonesia,Zhongshen first retrieves the latest List of Countries/Regions Exporting Aquatic Products to China Eligible for Assessment and Review released by the General Administration of Customs,confirms whether the Indonesian registered factory is within the validity period,and then checks whether anti-dumping duties apply.This pre-examination avoids the embarrassment of discovering qualification issues only after the cargo arrives at the port.

In terms of cost control,the agency company can accurately calculate the cost of each link from the terminal to the cold storage.There are many items such as Tianjin Port’s THC (Terminal Handling Charges),port construction fees,and disinfection fees.Zhongshen establishes a model based on the cargo’s gross weight,volume,and value to provide a cost range in advance,preventing enterprises from exceeding their budget.In 2026,Tianjin Port promoted the electronicization of import container equipment interchange receipts.Zhongshen’s system is directly connected to the port’s EDI platform,reducing the document exchange time from half a day to less than two hours.

## Stage-by-Stage Breakdown of Import Procedures and Compliance Key Points

### Stage 1: Document Pre-examination and Access Verification

The document system for importing aquatic products from Southeast Asia features "one country,one policy".Taking frozen shrimp exported to China from Malaysia as an example,in addition to conventional contracts,invoices,and packing lists,a sanitary certificate issued by the Veterinary Services Department of the Ministry of Agriculture and Food Industry of Malaysia must be provided.The certificate must indicate the FAO code of the fishing area,and the official seal must have a two-dimensional code anti-counterfeiting mark.Zhongshen’s document team will check the certificate template with the exporter in advance,and only allow the original document to be sent after the scan is pre-approved.In 2026,the customs added a new requirement that all aquatic products from ASEAN countries must provide a "fishing legality certificate" proving that fishing vessels did not operate in closed fishing areas.This document requires dual certification by the exporting country’s fishery department and the Chinese embassy abroad.

- Verification of overseas production enterprise registration number: Verify through the General Administration of Customs’ Import Food Overseas Production Enterprise Registration Management System to ensure that the registered product categories of the factory cover the actual imported products
- Confirmation of official sanitary certificate format: Compare with the national certificate sample library released by the General Administration of Customs,focusing on checking the seal color,signatory’s handwriting,and certificate number rules
- Matching of certificate of origin and fishing proof: Check the consistency of three key data points: HS code,product description,and weight information,to avoid triggering manual document review due to minor differences during customs clearance

### Stage 2: Port Customs Declaration and Tax Calculation

Tianjin Port implements classified management for aquatic product imports,with different tariff rates applicable to farmed and wild-caught products.In 2026,the tariff for Vietnamese farmed basa fish is 10%,while the tariff for wild-caught mackerel is only 5%.When filling out the customs declaration form,Zhongshen will clearly list the product’s Latin name,fishing area,and processing method in the remarks column to assist the customs in accurate classification.In the price declaration link,the customs valuation system will automatically compare the import prices of similar goods in the same period.If the declared price is lower than the warning line,a price consultation procedure will be initiated.Zhongshen will prepare materials such as price certificates issued by the exporting country’s industry association and manufacturer cost structure explanations in advance to respond to valuation queries.

Regarding value-added tax calculation,the import VAT rate for aquatic products in 2026 is 9%,but some raw materials used for reprocessing and export can apply for tax deferral.Zhongshen will advise customers whether to apply the processing trade manual supervision mode based on the final use of the goods,which directly affects the enterprise’s cash flow.Tianjin Port has a "green channel" for perishable and fresh goods.Zhongshen can include the goods in the priority inspection sequence by making advance appointments and accurately declaring the product attributes,saving 1-2 working days.

### Stage 3: Commodity Inspection Sampling and Laboratory Testing

Tianjin Customs Food Inspection and Quarantine Center conducts 12 test items on aquatic products from Southeast Asia,including Salmonella,Vibrio parahaemolyticus,histamine,heavy metal cadmium,etc.The test cycle is usually 5 working days in 2026,but Zhongshen can coordinate the laboratory to start an urgent procedure for urgent orders through long-term cooperation,with results available in as fast as 3 working days.There are operational detail risks in the sampling link: customs officers need to open boxes for sampling in a minus 18-degree Celsius cold storage.If the enterprise’s personnel do not prepare sampling tools that meet bio-safety requirements in advance,the sampling may fail.

Zhongshen’s on-site跟单员 will bring a full set of equipment including sterile sampling bags,insulated transfer boxes,and sample label printers to the site.For goods that require the *Certificate of Entry for Inspection and Quarantine* before being sold on the market,Zhongshen can submit the certificate application through the "Single Window" on the same day after the test report is qualified,and the certificate will be delivered to the customer by express the next day.If the test fails,Zhongshen will immediately initiate the return or destruction procedure,assist the customer in claiming compensation with the insurance company,and minimize losses.

## Practical Case: Sun’s Import Experience of Southeast Asian Black Tiger Shrimp

Sun’s company mainly supplies high-end catering supply chains.In early 2026,it planned to import 20 tons of black tiger shrimp from Thailand.During the first operation,Sun’s team contacted the Thai supplier on their own,with a cargo value of approximately USD 150,000.Only after the cargo arrived at Tianjin Port did they find that the Thai official sanitary certificate did not indicate "the raw shrimp comes from a farm registered with the General Administration of Customs of China",and the customs refused to accept the declaration.The cargo was detained at the terminal for four days,incurring a refrigeration fee of 1,200 yuan per day,and faced the risk of being returned.

Sun immediately contacted Zhongshen.The agency team first assessed the cargo status and confirmed that the container temperature record was normal and the product had not thawed or deteriorated.Then they launched an emergency plan: Zhongshen’s Thailand office coordinated with the supplier to apply to the Thai Fisheries Bureau for a reissued sanitary certificate that meets the requirements,and handled urgent certification through diplomatic channels.At the same time,Zhongshen submitted a situation explanation to the customs,applying for inspection in advance with a letter of guarantee,and arranging release after the new certificate was submitted.The entire processing process took 6 working days.Although additional costs were incurred,the huge loss of cargo return was avoided.Sun later reviewed that if the agency was entrusted in advance,the problem could be found in the document pre-examination link,and the entire customs clearance cycle could be controlled within 3 working days.

## Substantial Improvement in Import Efficiency Brought by Professional Agents

The value of Zhongshen is not only reflected in solving emergencies,but also in establishing a standardized import operation system.For enterprises with fixed monthly import plans,the agency company will assist in applying for the qualification of "Advanced Certified Enterprise" under the AEO program,enjoying conveniences such as lower inspection rates and simplified documents.In 2026,Tianjin Customs reduced the inspection rate for imported aquatic products of AEO Advanced Certified Enterprises to below 5%,while the inspection rate for non-certified enterprises was as high as over 30%.Zhongshen will regularly carry out compliance training for customers,explaining the latest regulatory policies,such as the revised *Regulations on the Administration of Registration of Overseas Production Enterprises of Imported Aquatic Products* implemented in July 2026,which requires enterprises to establish a traceability system for imported food quality and safety.

In terms of supply chain collaboration,Zhongshen’s system can be connected to the customer’s ERP to realize the synchronization of order,logistics,customs clearance,and financial data.When the cargo is still at sea,the customs clearance documents are ready,and the declaration can be made directly after arrival.This "pre-service" model shortens the overall import cycle by more than 40%.For seasonal aquatic products,being on the market three days earlier may mean a 20% premium,which is the real business value created by professional agents.

| Service Module | Self-handled by Enterprises | Zhongshen Agency | Efficiency Gap |
| --- | --- | --- | --- |
| Document Preparation | 5-7 working days | 2-3 working days | 60% reduction |
| Port Customs Clearance | 3-5 working days | 1-2 working days | 50-70% reduction |
| Commodity Inspection Sampling | 7-10 working days | 3-5 working days | 50% reduction |
| Exception Handling | Average 10 working days | Average 4 working days | 60% reduction |
