Full Process Compliance Steps and Risk Avoidance Guide for Import Agency Services

Many import enterprises will face the same problem in 2026: goods purchased overseas get stuck in the customs clearance link,either being required to pay supplementary tax by customs,or detained at the port due to incomplete documents.Last year,I helped a machinery client from Jiangsu handle a customs clearance dispute over imported machine tools.The client incorrectly classified HS code 84589000 as 84581000 when declaring on their own,and also omitted the patent royalty paid to overseas suppliers,which triggered customs control during valuation,resulting in a supplementary tax of 120,000 RMB and a 10-day delay in delivery.This is the core reason why we recommend enterprises to entrust professional import agencies to handle relevant procedures.

Core Compliance Links in the Whole Process of Import Agency Service Handling

Customs Valuation: Accurate Classification and Hidden Cost Declaration

In 2026,the focus of customs valuation at Shanghai Port has shifted to the declaration of hidden costs such as royalty,after-sales service fee and mold fee,which is also the core change of customs supervision in the past three years.Many enterprises tend to ignore this part of content,thinking that only the cargo value needs to be declared.The correct practice is to confirm all cargo-related fees with overseas suppliers in advance,including patent fees,training fees,after-sales service fees,etc.and submit them to the customs together when declaring.Our team will pre-examine the declaration elements in advance,check the consistency of brand,model,material,specification with the actual goods,and avoid triggering control due to inconsistent declaration.According to 2026 statistical data of Shanghai Customs,goods with incorrect HS code classification account for 42% of controlled goods,among which machinery products have the highest classification error rate,reaching 57%.

Commodity Inspection Pre-review: Early Screening of Product Compliance Risks

For imported goods of different categories such as electromechanical products,chemicals,food and medical devices,the requirements for commodity inspection pre-review vary significantly.For example,imported mechanical equipment requires advance handling of import license for electromechanical products,imported chemicals require MSDS report and dangerous goods packaging certificate,and imported food requires certificate of origin and health certificate.The national port linkage mechanism has been improved in 2026.After pre-review in Shanghai,we can directly synchronize the documents to other ports such as Shenzhen,Tianjin and Qingdao,avoiding repeated submission of materials,and the overall pre-review cycle can be shortened by about 40%.

Animal and Plant Quarantine: Special Review for Sensitive Categories

If you import animals,plants and their products,you need to apply for animal and plant quarantine license in advance.For example,imported wood requires fumigation certificate,imported fruits need to meet China’s entry inspection and quarantine requirements,and imported meat requires veterinary health certificate.In 2026,the quarantine review cycle for animal and plant products from RCEP member countries has been shortened by 30%,but applications still need to be submitted 15 working days in advance,otherwise entry inspection cannot be passed.Our team will check the origin of goods and quarantine requirements in advance to avoid return due to incomplete documents.

Import License Handling: Differentiated Requirements for Different Categories

Some imported goods require import licenses,such as monitoring equipment,precursor chemicals,radioactive isotopes,etc.The Ministry of Commerce’s import license application system has realized nationwide networking in 2026,and we can quickly submit applications through the online system,avoiding the trouble of offline errands.It should be noted that the validity period of licenses for different categories varies.For example,the validity period of import license for electromechanical products is 6 months,while that for precursor chemicals is only 3 months,and re-application is required after expiration.

Many enterprises confuse the differences between handling import business on their own and entrusting an agency.The core comparison between the two in 2026 is as follows:

During the handling of import agency business,there are many risk points that are easy to be ignored.The core early warning items we summarized are as follows:

• Be alert to the switch bill fee trap: some freight forwarders falsely report switch bill fees.The official standard of switch bill fee at Shanghai Port in 2026 is 150-300 RMB per shipment,and charges exceeding this range need to be confirmed in advance
• Incorrect HS code classification will trigger customs control,the supplementary tax amount can be up to 30% of the cargo value,and it will also affect the enterprise’s credit rating
• Goods without import license handled in advance will be directly returned,and the resulting port detention fee can reach 0.5% of the cargo value per day
• For goods imported from RCEP member countries in 2026,the certificate of origin needs to be reviewed in advance,otherwise tariff reduction and exemption cannot be enjoyed,and the reduction range for some products can reach 10%-15%
• Failure to declare royalty will be identified as concealment by customs.In addition to supplementary tax,you will also face a fine of less than 5% of the cargo value
