2026 Full Process Operation Guide for Import Customs Clearance and Declaration at Shanghai Port

Core Processes and Compliance Key Points for Import Customs Clearance and Declaration at Shanghai Port

As a foreign trade agency expert with 20 years of deep experience at Shanghai Port,we always regard "compliance access" and "risk pre-control" as the lifeline of import customs clearance.The new valuation regulations for high-value electromechanical equipment,chemical products and other categories launched by the General Administration of Customs in 2026,as well as the dynamic adjustment of RCEP rules of origin,require enterprises to shift the customs clearance process from "post-event rectification" to "pre-event prediction".The following disassembles key nodes of the entire import declaration chain from a practical perspective.

1.Customs Valuation: The Game Between Declared Price and Dutiable Value

Customs valuation is the core link of import customs clearance.The newly added "dynamic update mechanism for commodity price database" in 2026 requires that the deviation rate between the declared price and the transaction price of similar commodities in the same period shall be controlled within 5%.Three common risk points in practice need to be focused on for avoidance:

• HS Code Classification Error: A portable projector imported by an electronic enterprise was classified as "optical instrument" (tax rate 10%),while it should actually be classified as "audio-visual equipment" (tax rate 15%),resulting in an overpayment of 230,000 yuan in tax.Correct practice: It is recommended to apply for the Commodity Classification Decision from the customs in advance,and focus on checking three elements: material (metal/plastic shell),functional parameters (whether with built-in system),and usage scenarios (office/home).
• Disconnection Between Declaration Elements and Actual Goods: When a cosmetics enterprise declared "natural plant face cream",it failed to clearly mark the ingredient of preservative methylisothiazolinone (MIT),resulting in customs inspection and control.In 2026,the customs added a mandatory requirement of "allergen labeling" for cosmetics,so it is necessary to check the differences between EU Cosmetics Regulation (EC 1223/2009) and China’s Cosmetics Supervision and Administration Regulation in advance.
• Missing Price Proof Chain: Import of high-value equipment requires a complete chain of "overseas procurement contract + foreign exchange payment voucher + international transport documents".An auto parts enterprise lacked the conversion proof from FOB to CIF,resulting in the customs levying tax according to the "maximum price limit",with a loss of 470,000 yuan.

2.Commodity Inspection Pre-review: Pre-verification of Quality and Safety of Imported Commodities

In 2026,the State Administration for Market Regulation issued the Optimization Plan for Import Commodity Inspection and Supervision Mode,implementing the mechanism of "risk classification pre-review + port random inspection" for legally inspected commodities.The following three categories of commodities need to complete commodity inspection pre-review in advance:

Typical Case: The orthopedic internal fixation devices imported by a medical device company from Germany were delayed for 15 days in customs clearance due to missing labels after arriving at the port,as the pre-review of the Medical Device Product Registration Form was not completed in advance,resulting in demurrage of 86,000 yuan.

3.Special Supervision: Animal and Plant Quarantine and License Processing

Special attention shall be paid to the import of animal and plant products:

• Validity of Quarantine Certificates: Meat products shall provide "official quarantine certificate of the exporting country + disinfection certificate of means of transport",and the requirement of "African swine fever virus PCR test report" is added in 2026
• Animal and plant derived commodities: The validity period of the Entry Animal and Plant Quarantine License shall be checked.In 2026,the policy of "license first,declaration later" is implemented for fresh fruits from Australia and New Zealand
• License processing cycle: Since 2026,imported used equipment outside the 3C certification catalog shall apply for the Import Filing Certificate for Used Electromechanical Products 90 working days in advance.The inspection rate at Shanghai Port has increased to 35%,so it is necessary to prepare "equipment service life certificate + maintenance records" with focus

A wood processing enterprise was returned by Shanghai Port Customs because the imported "North American oak boards" lacked the fumigation certificate with IPPC mark,resulting in a total of 120,000 yuan in round-trip freight and storage fees.

4.2026 Shanghai Port Customs Clearance Risk Early Warning and Response

Combined with the latest policy developments,the following three types of risks need to be focused on for prevention and control:

• Exchange loss from exchange rate fluctuation: In 2026,the fluctuation range of RMB against the US dollar is expanded to 6.8-7.2.It is recommended to adopt the combined strategy of "batch foreign exchange payment + forward foreign exchange settlement and sale".Zhongshitong can provide real-time exchange rate monitoring service
• Hidden cost trap: Freight forwarders may falsely report "document exchange fee (2,000-5,000 yuan per B/L)" and "demurrage (from 500 yuan per day)".It is recommended to sign a Lump Sum Fee Agreement with the agent in advance to clarify the "demurrage ceiling" and "inspection coordination fee standard"
• Time limit impact of holidays: During Ramadan 2026 (March 25 to April 23),the customs clearance efficiency of Dubai Port,UAE,drops by 40%,resulting in the inability to pick up goods within 3 days after arrival at the port.Document pre-review shall be completed 15 days in advance
