Full Process and Compliance Operation Practice Guide for Seafood Import Customs Declaration in Guangzhou

As a benchmark city for catering consumption in China,Guangzhou has maintained a high demand for high-quality dried seafood and frozen seafood all year round.In 2026,with the comprehensive upgrade of the domestic food safety supervision system,the inspection intensity for imported aquatic products at Guangzhou Port has been significantly strengthened.When importers bring high-value seafood such as abalone,sea cucumber and fish maw into the domestic market,they not only face the complicated international logistics environment,but also need to cope with strict access review,label compliance inspection and potential endangered species control.For enterprises without a professional customs clearance team,any negligence in document details may lead to cargo detention at the port,incur high container detention fees and storage costs,and even face the risk of return or destruction.

As a professional service institution deeply engaged in the foreign trade agency industry for more than 20 years,Zhongshen relies on the resources of its Shanghai headquarters and covers major ports across China including Guangzhou.We are familiar with the quarantine preferences and document review logic of Guangzhou Customs for seafood from specific origins,and can provide customers with integrated solutions from document pre-review,international transportation to port customs declaration,commodity inspection and disinfection,warehousing and distribution.Through our professional intervention,enterprises can outsource tedious compliance work and focus on the sales and expansion of the domestic market.

Decomposition of Import Operation Process and Risk Control

For Guangzhou imported seafood business,we decompose the entire import chain into three core stages,each with its own specific compliance requirements and operational difficulties.

Preliminary Document Pre-review and Access Confirmation

Before the goods are shipped,Zhongshen will assist customers to conduct detailed document pre-review.The core of this stage is to confirm the access qualification of the product.Not all seafood from all countries is allowed to enter the Chinese market,and different products correspond to different quarantine access lists.

• Certificate of Origin and Health Certificate Review: We need to confirm whether the official health certificate provided by the overseas supplier meets the latest version requirements of the General Administration of Customs of China.Especially since 2026,the requirements for the accuracy of production enterprise registration number,product name and processing technology description on the certificate are extremely high,any information inconsistent with the actual goods will be judged as non-conforming documents.
• Endangered Species Permit Application: If imported species such as abalone and sea cucumber are listed in the appendix of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES),the import and export permit must be obtained in advance.Zhongshen will guide customers to prepare relevant application materials according to the species scientific name and country of origin,to ensure that the "green card" for customs clearance is obtained before the goods arrive.
• Chinese Label Review: Imported pre-packaged food must have a Chinese label that meets the standards of GB7718 and GB28050.We will check whether the ingredient list and nutrition facts on the label meet national standards,to avoid rectification risk caused by improper use of additives or incorrect labeling format.

International Transportation and Cold Chain Warehouse Management

Seafood products have extremely high requirements for temperature control,especially frozen seafood.Zhongshen has integrated high-quality international logistics resources to provide customers with door-to-door service from the port of departure to Guangzhou Port.

• Cold Chain Temperature Control: During transportation,we require the shipping company and trailer company to record temperature data throughout the whole process,to ensure that the goods are kept in the specified low-temperature environment during transportation.For high-end ingredients such as ultra-low temperature tuna,we will arrange dedicated refrigerated containers and provide independent temperature recording reports for commodity inspection.
• Packaging Specification: For dried seafood,we focus on checking the moisture-proof and mildew-proof performance of the outer packaging.For frozen products,we ensure that the inner packaging meets the safety standards of food contact materials,to avoid secondary pollution caused by packaging damage during long-distance transportation.

Port Customs Declaration and Commodity Inspection Response

After the goods arrive at Guangzhou Port,they officially enter the customs declaration and inspection link,which is the stage with the most concentrated risks.

• Single Window Declaration: Zhongshen uses the "single window" platform to accurately fill in commodity code,country of origin,gross and net weight and other data.We will select the most favorable tax rate declaration path for customers according to the latest 2026 tariff policy,for example,using RCEP agreement tariff preferences to reduce import costs.
• Inspection Cooperation: Customs may conduct sampling inspection on the goods.In case of inspection,our operation team will rush to the site immediately to assist customs officers in unpacking and sampling.For items requiring laboratory testing,we will closely follow up the testing progress and communicate with the laboratory in time to ensure the test report is issued as soon as possible.
• Label Rectification and Sanitation Treatment: If commodity inspection finds problems with the Chinese label,we will immediately arrange pasting and rectification in the supervised warehouse; if the outer packaging of the goods has dust or needs epidemic prevention treatment,we will assist in contacting a professional disinfection company to carry out sanitation treatment,ensuring rapid release of the goods.

Comparison of Import Elements for Common Seafood Products

Different categories of seafood products have significant differences in import operation.To help customers better understand the operation priorities of various products,we have sorted out the following comparison table.

Practical Case Sharing: Solving Label and Endangered Permit Problems

Mr.Shi,a high-end ingredient trader in Guangzhou,planned to import a batch of dried abalone from South America in early 2026.Since this was his first time importing this category,he was not familiar with relevant procedures.Only after the goods were shipped did Mr.Shi find that the Chinese label provided by the supplier lacked the mandatory "unsuitable groups" warning,and this batch of abalone involves CITES Appendix II species,but he has not yet applied for the import and export permit for endangered species.

Mr.Shi immediately contacted Zhongshen for emergency assistance.After receiving the commission,our operation team first guided Mr.Shi to use the transit time of the goods to quickly sort out relevant trade contracts,invoices and CITES export permits issued by the overseas party,and applied for the "Import and Export Permit" from the endangered species management department.When the goods arrived at Guangzhou Huangpu Port for declaration,the customs system triggered a label review instruction.Since we predicted the risk in advance,we had prepared a new label design scheme that meets national standards,and arranged professional personnel to carry out pasting and rectification as soon as the goods entered the supervised warehouse.

Finally,this batch of dried abalone,which originally faced the risk of return,successfully completed label rectification and endangered permit verification under the coordination of Zhongshen,and completed customs clearance and release within 48 hours after declaration.Mr.Shi not only avoided high return freight,but also caught up with the pre-Spring Festival sales season and guaranteed the delivery of customer orders.

Conclusion

The imported seafood business seems simple,but it actually involves coordinated supervision of multiple departments including customs,commodity inspection,endangered species management authority and taxation.Under the background of strict supervision in 2026,it is often difficult for enterprises operating independently to cope with sudden inspection requirements and policy changes.With standardized operation procedures and rich practical experience,Zhongshen can effectively identify and resolve potential risks.From meticulous document review to rapid response to port inspection,we provide a solid compliance firewall for Guangzhou importers,ensuring that every batch of precious high-quality seafood can enter the domestic market safely and efficiently.
