Import Customs Clearance for Murex Shell Speeds Up by 30% | 2026 Customs Valuation and Quarantine Pitfall Avoidance Guide

Key Access Requirements for Murex Shell Import

Murex Shell is an edible aquatic mollusk.In 2026,customs supervision for its imports first verifies access qualifications,allowing imports only from countries/regions that have obtained qualification for exporting edible aquatic animals to China.Currently,the main source countries for normal imports are RCEP member states such as Indonesia,Thailand,and Malaysia.Prior to import,the Import Animal and Plant Quarantine Permit must be applied for in advance,and the designated port on this permit must be consistent with the actual declaration port; otherwise,the goods will be directly returned.

The standard HS code for Murex Shell is 0307719000,with a Most Favored Nation (MFN) tariff rate of 10% and a VAT rate of 9%.For those holding a FORM E Certificate of Origin issued by an RCEP member country and meeting the rules of origin,zero tariff preference can be enjoyed.For a single container of Murex Shell worth 100,000 yuan,a tax saving of 10,000 yuan can be directly achieved.Among Murex Shell import businesses handled by our company last year,32% of customers failed to enjoy preferential tax reduction due to non-standard description and HS code filling on the Certificate of Origin,resulting in unnecessary additional costs.

Key Operational Points for the Entire Process of Murex Shell Import

Pre-declaration Document Review

Murex Shell belongs to cold chain food.Cross-verification of all documents must be completed before declaration to avoid goods being detained due to document inconsistency after arrival at the port.

• Aquatic animal quarantine certificate issued by the official of the exporting country,which must indicate the fishing/farming registration number,be valid,and have the same consignee name as the domestic importer
• Certificate of Origin must accurately fill in HS code,country of origin,and total value of goods.Box 13 of the RCEP Certificate of Origin must check "Back-to-Back" or "Direct Transport"; otherwise,the preferential tariff rate cannot be enjoyed
• Full temperature records for cold chain transportation,requiring stable temperature at 0-4℃ during transportation.If the temperature fluctuation exceeds 2℃,customs will directly conduct microbial testing with a cycle of at least 7 days,resulting in high demurrage fees
• Domestic importer’s import and export operation right,food business license,and Import Animal and Plant Quarantine Permit must be valid,and the business scope must cover import of edible aquatic products

Customs Declaration and Inspection Procedures

In 2026,the targeted inspection rate for imported Murex Shell is 22%,mainly checking three dimensions: 1.Whether heavy metals and parasites exceed standards; 2.Whether declared weight and individual specifications are consistent with the actual goods; 3.Whether they come from non-qualified production areas.Our company will conduct pre-inspection of goods before declaration,check consistency between declaration elements and actual goods,and predict valuation risks in advance to avoid tax supplement or investigation caused by price query.

In March 2026,Mr.Rao imported 12 containers of frozen Murex Shell from Thailand.When declaring on his own,he failed to enjoy RCEP tax reduction due to incorrect HS code filling on the Certificate of Origin,and was also questioned by customs valuation for under-declaration.He paid an additional tax of 120,000 yuan and incurred 3 days of demurrage fees.Later,when he turned to our company,we reviewed all documents 10 days in advance,helped him correct HS code classification,and submitted purchase contracts,foreign exchange payment vouchers,and foreign factory quotations to customs for valuation pre-approval.For the subsequent 3 batches of goods,zero tariff preference was enjoyed for each container,the customs clearance time was reduced from 5 days to 2 days,and no additional costs were incurred.

Risk Alert for Murex Shell Import

First,pay attention to production area access risks.In 2026,some production areas of several Southeast Asian countries have been suspended from exporting to China due to detection of harmful organisms.Before import,the latest access list must be checked to avoid blind procurement,otherwise the goods will only be returned or destroyed after arrival at the port,resulting in a loss of at least 100,000 yuan/container.Secondly,pay attention to the bill of lading exchange fee trap.Many foreign freight forwarders will charge additional bill of lading exchange service fees and document fees after arrival at the port.Our company’s global agency network will check all fee details with the shipping party in advance,and the quotations provided to customers are all-inclusive prices with no hidden charges.
