Professional Import Customs Declaration and Inspection Agent, One-stop Compliance Customs Clearance Service Support for National Ports

Core Compliance and Practical Key Points for Import Customs Declaration and Inspection

Many import enterprises only find incomplete documents and incorrect codes after goods arrive at the port,leading to soaring detention fees and even temporary detention of goods.Professional import customs declaration and inspection agents can help enterprises avoid these risks and improve customs clearance efficiency.In 2026,global trade rules continue to be updated,the EU Carbon Border Adjustment Mechanism is fully implemented,and the US Inflation Reduction Act subsidy restrictions on imported new energy products are further tightened,all of which require import enterprises to have more professional compliance capabilities.

1.Accurate Declaration Logic for Customs Valuation

In 2026,the valuation system of Shanghai Customs has been upgraded to a big data intelligent comparison model,which automatically matches data such as transaction prices,transportation costs,and commission ratios of similar goods worldwide.At the end of 2025,we served a machinery import enterprise in Suzhou.When they declared German imported machine tools on their own,they reported the FOB price as 120,000 euros,but the system prompted that the average transaction price of the same model of equipment was 135,000 euros,requiring a 20% tariff difference to be paid.We assisted the client in providing the original factory bulk procurement agreement,cross-border transportation contract and third-party price appraisal report,proving that the quoted price was a real preferential transaction price,and finally passed the valuation smoothly,avoiding nearly CNY 100,000 of extra expenses.

Common risks in the valuation link include underreporting or overreporting of prices,concealment of commissions or royalties.Enterprises need to prepare a full set of transaction documents in advance to ensure that the declared price is consistent with the actual transaction.

2.Pre-control Key Points for Commodity Inspection Pre-examination

Commodity inspection pre-examination is not a mere formality,but a prior review of whether goods meet the quarantine requirements of the importing country.In 2026,the National Medical Products Administration updated the import cosmetics filing system,requiring upload of more detailed product ingredient test reports.A cosmetics import enterprise in Shenzhen failed to prepare relevant materials in advance,resulting in 7 days of detention of goods arriving at the port,and incurred nearly CNY 30,000 in storage fees.

Commodity inspection requirements vary for different categories of goods: food products require certificates of origin and health certificates; hazardous chemicals require MSDS and dangerous goods packaging appraisal forms; animal and plant products require quarantine approval forms and fumigation and disinfection certificates.We will complete pre-examination before goods are shipped,and check for document loopholes in advance.

3.Full-process Processing of Import Licenses

In 2026,the Ministry of Commerce updated the Catalogue of Goods Subject to Automatic Import License Management,adding 12 types of new energy equipment,including energy storage inverters,hydrogen fuel cells,etc.If enterprises do not apply for corresponding licenses in advance,goods will not be able to be declared after arriving at the port,and may even be temporarily detained by customs.

The processing cycle of import licenses is usually 3-5 working days,and the validity period is 6 months.Enterprises need to plan the processing time in advance to avoid customs clearance delays caused by reapplication after expiration.We will track the progress of license processing to ensure that all documents are complete before goods arrive at the port.

4.Risk Control Key Points for Global Trade Compliance

In 2026,the tariff reduction coverage of RCEP member states has reached 95%.Submitting the certificate of origin correctly can save 5%-10% of tariffs,but many enterprises lose a lot of costs because they fail to apply for the certificate of origin in time.In addition,the EU CBAM requires imported products such as steel,cement,and aluminum to provide carbon footprint reports,otherwise additional tariffs will be imposed.Many domestic enterprises failed to understand this rule,resulting in detention of goods after arriving at the port.

Our global agency network covers Europe,Southeast Asia,North America and other regions,which can track the latest trade policies of destination countries in real time and make compliance plans for enterprises in advance.

Preparatory checklist for import customs declaration and inspection:

• Entrust a professional institution to complete pre-classification of HS codes in advance to avoid classification errors
• Collect full set of transaction documents: invoice,packing list,bill of lading,certificate of origin,contract
• Confirm whether the goods require an import license and submit the application in advance
• Understand the quarantine requirements of the importing country,and complete packaging,fumigation and other treatments in advance
• Confirm with the foreign supplier whether the shipping marks and labels of the goods meet domestic standards

In March 2026,we assisted a chemical enterprise in Shanghai to import coatings from South Korea.The client failed to provide MSDS when declaring on their own,and was placed under control by Yangshan Customs.We assisted the client in reissuing the MSDS and dangerous goods packaging appraisal form,and completed the commodity inspection pre-examination in advance.Finally,the customs clearance was completed in only 3 days,which was 70% shorter than the client’s expected time.

As a professional agent deeply rooted in Shanghai Port,we have the ability to declare across regions at national ports,and have cooperative outlets in major ports such as Shenzhen,Tianjin,Qingdao,etc.which can solve compliance problems of cross-regional import business in a one-stop manner.Our risk control system will check all potential risks in advance to avoid unnecessary losses for enterprises due to compliance issues.
