# Complete Process Analysis and Compliance Operation Guide for Green Mussel Import Customs Clearance

In 2026,domestic consumers’ demand for high-quality seafood continues to rise.With its tender taste and rich nutritional value,green mussel has become a popular category in the imported seafood market.Its main supply sources are concentrated in the sea areas of New Zealand,Ireland,Chile and other regions.However,importing green mussel is not a simple buy-sell transaction.The timeliness of cold chain logistics,strict inspection and quarantine standards and complex documentary requirements behind it often make it difficult for many importers new to this field.Once the goods are detained at the port,their freshness will be greatly reduced,and they even face the risk of being returned or destroyed.

In this complex supply chain,**Zhongshen** plays a critical role as a "compliance manager".We not only provide independent logistics services,but also integrate core links including customs declaration and inspection,foreign exchange settlement and warehouse management to build a solid risk firewall for customers.For the special product of green mussel,we rely on 20 years of industry experience to accurately control every operation node,ensuring that goods enter the domestic market at the fastest speed under the premise of compliance.

## Document Pre-review and Compliance Confirmation Before Import

As an edible aquatic animal,the import of green mussel is strictly supervised by the General Administration of Customs and inspection and quarantine authorities.Before goods shipment,**Zhongshen** will assist customers to conduct in-depth pre-review of the full set of documents,which is the first line of defense to avoid return risk.

According to the latest regulatory requirements in 2026,green mussel import must provide a health certificate issued by the official authority of the exporting country.The certificate must clearly mark the scientific name of the product,processing method,fishing or culture area,and confirm that the product does not come from epidemic areas.In addition,the information on the certificate of origin must be consistent with that on the health certificate,and the Entry Animal and Plant Quarantine Permit must be applied for before shipment.The product name,quantity and origin information on the permit must fully match the actual goods.We will check the above key information one by one during the document pre-review stage to ensure that "documents match the goods".

- **Official Health Certificate**: It must include Chinese-English bilingual content,and clearly indicate the Latin scientific name of the product and processing date.
- **Certificate of Origin**: It proves the origin of goods and is an important voucher for enjoying tariff preferences.
- **Entry Animal and Plant Quarantine Permit**: A mandatory qualification for domestic consignees,which must be applied in advance.
- **Contract,Invoice,Packing List**: Basic trade documents,the transaction price and freight and insurance premium must be truthfully declared.
- **Chinese Label**: Must comply with GB7718 and GB28050 standards,and the filing information must be confirmed before shipment.

## Timeliness Control of Cold Chain Logistics and Warehouse Management

Green mussel is extremely sensitive to temperature,and its freshness directly determines its market value.In the logistics link,**Zhongshen** uses professional cold chain logistics resources to ensure full-process temperature control from overseas cold storage to domestic ports.

For chilled green mussel,the transportation temperature is usually controlled between 0and 4; for frozen green mussel,the temperature must be maintained below -18.We recommend customers to use containers equipped with temperature recorders,and read the data immediately upon arrival at the port to ensure no cold interruption or temperature fluctuation occurs during transportation.If goods cannot be cleared immediately after arriving at the port,we will transfer them to a supervised warehouse with constant temperature function,to avoid goods deterioration caused by exposure or high temperature in ordinary port environment.Through refined logistics and warehouse management,we effectively solve the core pain point of "timeliness" in seafood import.

## Practical Key Points of Port Customs Declaration and Inspection

Customs declaration is the core link of green mussel import.Different from ordinary goods,aquatic products must be imported through designated ports,and must accept double inspection by customs and commodity inspection.In operation,**Zhongshen** will formulate differentiated declaration strategies according to different countries of origin of goods.

In declaration elements,we focus on verifying the "registration number of overseas manufacturing enterprise" and "product HS code".Green mussel is usually classified under heading 0307 or 1605,different codes correspond to different tariff rates and regulatory conditions.In the inspection link,customs will focus on checking whether the packaging is intact,whether there is rot or deterioration,and sample proportionally for laboratory testing.Testing items include heavy metals (such as cadmium,lead),microbial indicators and parasites.Once the test fails,the entire batch of goods will be destroyed.

To reduce the inspection rate,**Zhongshen** will conduct a risk assessment on goods before declaration,organize clear goods description materials,and make standardized declaration in the customs system to ensure the logic of document data,so as to improve customs clearance efficiency.

| Country of Origin | Characteristics of Health Certificate Requirements | Recommended Customs Clearance Port | Common Risk Warning |
| --- | --- | --- | --- |
| New Zealand | Must be issued by official MPI,with FAO fishing area code marked | Shanghai,Tianjin,Guangzhou | High risk of excessive cadmium content |
| Ireland | Must mark processing plant registration number,in Chinese and English bilingual | Shanghai,Shenzhen | Label review is strict,easy to be returned due to format non-compliance |
| Chile | Must be issued by SAG,with fishing vessel name marked | Shanghai,Qingdao | High probability of Vibrio parahaemolyticus detection |

## Practical Case: Resolution of Manager Song’s Import Crisis

Manager Song from a catering supply chain enterprise in Shanghai planned to import a batch of frozen green mussel from New Zealand in early 2026.As it was his first time handling this business,after he shipped the goods by himself,the goods were targeted for inspection by customs when arriving at Shanghai Yangshan Port.The inspection found that although the quality of the goods itself was qualified,the Chinese label on the outer packaging did not mark "allergen warning" as required by the new 2026 regulations,and there was a minor deviation between the fishing area code on the health certificate and the declaration information.

The customs immediately issued a rectification notice,requiring rectification to be completed within the specified time,otherwise the goods would be returned.Facing urgent time pressure,Manager Song contacted **Zhongshen** urgently.After receiving the entrustment,we immediately sent a specialist to the site,assisted Manager Song to complete the label adding and rectification in the supervised warehouse,and communicated with the official authority of the exporting country to quickly obtain a supplementary explanation letter.Relying on our experience in communicating with customs,we assisted the customer to submit a detailed rectification report,and finally completed all compliance operations within the specified time,and the goods were released smoothly.Manager Song not only avoided huge losses from return,but also entrusted all subsequent import business to us after this cooperation.

## Conclusion

Green mussel import seems simple,but actually every link is closely connected.Any document defect or logistics negligence may lead to goods detention or even destruction.Relying on 20 years of deep cultivation in the industry,**Zhongshen** transforms the complex customs clearance process into standardized service products.From early document pre-review,mid-term cold chain monitoring,to later response to customs declaration and inspection,we provide a full-process,one-stop solution.Choosing a professional import agency can not only greatly improve customs clearance efficiency,but also effectively reduce compliance risks,allowing importers to focus on market sales without any worries.
