Aimer's Imported Swimwear Customs Clearance Pitfall Avoidance: Practical Method for 3-day Fast Clearance to Save 15% Tariff

Core Premise of Aimer’s Imported Swimwear Customs Clearance: Accurate HS Code Classification

At the end of 2025,Supervisor Xie processed a batch of Italy-origin imported swimwear under Aimer’s agency.The cargo owner incorrectly filled the spandex content from 22% to 18% during declaration,which directly triggered customs control inspection,resulting in 7 days of port detention and generating RMB 123,000 of demurrage fee and storage fee.In 2026,the customs has upgraded the verification rules for HS code classification of textile products.Swimwear falls into different HS codes based on weaving method,target user group and material composition,with corresponding significant differences in tariff and regulatory requirements.Wrong classification will directly lead to extra tariff payment or cargo detention.

Most of the imported swimwear under Aimer’s agency contains over 80% of polyester fiber and spandex,and some high-end models are added with natural fibers such as silk and wool.Priority of component proportion shall be noted during classification: swimwear with synthetic fiber proportion over 50% shall be classified into the synthetic fiber category codes first,and those with high natural fiber proportion shall be classified into corresponding natural fiber codes.For swimwear imported from RCEP member states (such as South Korea,Japan,ASEAN),eligible certificate of origin can be provided to enjoy 0-3% agreement tariff,which can reduce the tax cost by at least 5%.

Practical Operation Points for the Whole Customs Clearance Process of Aimer’s Imported Swimwear

1.Commodity Inspection Pre-review

In 2026,the customs has upgraded the safety and health testing standards for close-fitting textile products.Formaldehyde,PH value and decomposable carcinogenic aromatic amine dyes (azo dyes) are mandatory inspection items.The imported swimwear under Aimer’s agency is classified as textile products in direct contact with skin,and non-compliant testing result will directly lead to return or destruction.In practical operation,it is recommended to send 5 representative samples to a third-party testing institution recognized by Shanghai Customs for pre-test before shipment.The test report can be issued within 7 working days,and shipment can be arranged only after the product meets GB 18401-2010 Category B standard,so as to avoid losses caused by non-compliant testing after arrival.Previously,one of our clients imported swimwear from Southeast Asia,the azo content exceeded the standard by 0.3%,and the goods were directly returned,resulting in a total loss of RMB 270,000 for goods value and round-trip freight.

2.Animal and Plant Quarantine

If the imported swimwear under Aimer’s agency contains animal-derived components such as silk,wool and animal leather,the official animal and plant quarantine certificate issued by the exporting country shall be provided,to prove that the product is free from pests and diseases and meets China’s quarantine requirements.Quarantine certificates issued by RCEP member states are eligible for the fast release channel at Shanghai port,whose customs clearance efficiency is 48 hours faster than ordinary goods.For swimwear containing animal fibers imported from the European Union,additional non-epidemic zone certificate shall be provided to avoid triggering animal and plant quarantine control.

3.Customs Price Verification Response

In 2026,the customs has updated the price verification model for textile and apparel products,which refers to the national import declaration prices of swimwear of the same brand,same material and same specification in the past 6 months.Most of the imported swimwear under Aimer’s agency are products of internationally well-known brands,the probability of triggering price verification due to under-declared price is as high as 32%.To avoid relevant risks in practical operation,it is recommended to prepare full set of trade documents in advance,including original manufacturer invoice,foreign exchange payment voucher,trade contract,freight and insurance premium documents.For goods under EXW terms,payment vouchers for freight and insurance premium of the overseas section shall also be provided to prove the authenticity of the declared price.In early 2026,we processed one batch of Aimer’s imported swimwear from South Korea,the FOB price declared by the client was 7% lower than the customs reference price.We prepared the brand owner’s pricing letter and the 12% bulk purchase discount agreement certificate in advance,and completed the price verification within 3 working days without extra supplementary tax.

4.Special Qualification Handling

If the imported swimwear under Aimer’s agency has decorative accessories containing endangered animal and plant components (such as rare animal leather charms,coral decorations),the Import Permit for Wild Fauna and Flora shall be applied in advance,which takes 20 working days for processing.The application must be completed before shipment,to avoid port detention and demurrage fee caused by no valid certificate after arrival.Ordinary swimwear does not require extra import license,and can be declared normally as long as the business scope includes textile import permission.

Common Risk Warning for Aimer’s Imported Swimwear

• Risk of inconsistent documents: In 2026,the inspection rate for imported textiles at Shanghai port is 18%.The declared brand,material,size and style number must be completely consistent with the physical hang tag and care label.Any inconsistency found will lead to immediate cargo detention,amendment of declaration form,and the generated demurrage fee and form amendment fee shall be borne by the cargo owner.In severe cases,the act will be identified as untruthful declaration,with a fine of 5%-30% of the goods value.
• Risk of foreign exchange loss: In 2026,the fluctuation range of RMB against Euro and USD has expanded to ±3%.For orders settled in foreign currency,it is recommended to lock the forward exchange rate in advance to avoid extra foreign exchange loss during payment.Our calculation shows that for an order of 1 million Euros,2% exchange rate fluctuation will generate extra cost of about RMB 140,000.
• Traps of document exchange fee: Many overseas freight forwarders will charge extra document exchange fee,document fee and manifest entry fee after goods arrival,and some of the fees are even 3 times the public quotation.It is recommended to confirm all the details of arrival expenses with overseas freight forwarders before shipment,and get the official stamped expense list,to avoid arbitrary extra charges after arrival.
