2026 Full Process of Shanghai Import Customs Declaration: Guide to Customs Valuation and Commodity Inspection

Core Nodes and Risk Prevention and Control of the Full Process of Trade Import Customs Declaration

As a key hub of the international trade chain,import customs declaration shows two new trends in 2026: First,the online verification of RCEP certificates of origin has been upgraded,and enterprises shall complete the filing 3 working days in advance.Second,the customs valuation system has added a "Global Price Database",which imposes stricter requirements on the traceability of transaction prices of high-value equipment.The core operations are disassembled below from three parts: access permission,port operation and risk early warning.

I.Customs Valuation: The Game Point from Declaration to Release

1.Valuation Logic and Data Support

The customs implements the "three-level valuation model" in 2026: The first level compares the declared price with the average price of similar commodities worldwide (applications with an error within ±5% are automatically approved); the second level triggers the verification of the "transaction value method for identical goods" (import declaration forms and bills of lading of the recent 3 months shall be provided); the third level launches the "deductive value method" (applicable to high-value equipment worth more than 2 million yuan,and domestic sales invoices and profit margin calculations shall be provided).

• When declaring,the "Statement of Price Influencing Factors" shall be uploaded simultaneously: such as overseas storage fees under EXW terms,marine insurance fees under FOB terms,etc.In 2026,the requirement for bonded warehouse data verification for the "9710/9810 cross-border e-commerce mode" is added.
• Avoid the "under-declared price" trap: A chemical enterprise triggered customs valuation because its declared price was 18% lower than the average price of similar products,and the total amount of tax repayment plus delayed declaration fee reached 23% of the cargo value.

2.Pre-classification and Handling of Classification Objections

It is recommended that enterprises complete HS Code pre-classification through the China International Trade Single Window 48 hours before customs declaration,and focus on the tax rate difference between 9018 Optical Instruments and 9020 Medical Equipment (15% for the former vs 7% for the latter).Zhongshitong provides a "green channel for classification disputes",which can cooperate with the Classification Center of Shanghai Customs to issue pre-classification certificates,shortening the processing cycle of classification disputes by 5-7 days on average.

II.Commodity Inspection Pre-review and Operation of Specially Regulated Goods

1."Three No Principles" for Commodity Inspection Pre-review

Under the "release first,inspection later" supervision mode in 2026,the pre-review link can intercept more than 70% of substantive risks: Do not submit forged Certificate of Entry Inspection and Quarantine; Do not conceal the actual weight of goods (e.g.a 20kg carton marked as 15kg by mistake will lead to follow-up inspection); Do not delay the filing of imported food labels (shall be completed 14 days before the goods arrive at the port).

• Food imports require advance filing: Imported infant formula milk powder shall provide the "Registration Certificate of Infant Formula Milk Powder Product Formula",and the mandatory notarization requirement for "Chinese translation of labels" is added in 2026.
• Animal and plant products shall be submitted with: Entry Animal and Plant Quarantine Permit (applied 21 days in advance),Overseas Veterinary Health Certificate (shall include statements such as "free of African Swine Fever","free of Foot and Mouth Disease",etc.).

2."Double 72-hour" Rule for Dangerous Goods Import

After the update of dangerous goods labels in 2026,23 new restricted categories are added (e.g.lithium battery packs shall comply with the UN38.3 standard).Key operation points: Dangerous goods importers shall submit MSDS filing to the local customs 72 hours in advance (the mandatory requirement for "GHS Label" is added in 2026); The shipping company shall complete the manifest declaration of dangerous goods 72 hours in advance,otherwise double penalties of "demurrage fee + port change fee" will be triggered.

III."Three-step Speed-up Method" for Customs Clearance at Shanghai Port

Relying on the "Two-Step Declaration" policy of Shanghai Free Trade Zone,Zhongshitong summarizes: Step 1: "Declare first,transport later" (manifest confirmation is completed 48 hours before the goods arrive at the port); Step 2: "Separate Delivery and Consolidated Declaration" (consolidated declaration for the same batch of goods,applicable to bulk commodities entering the country multiple times within 30 days); Step 3: "Consolidated Taxation" (applicable to enterprises with an average of more than 5 declaration forms per month,saving about 85,000 yuan in margin interest per year).

• "Golden time" for inspection at Shanghai Port: Declare between 9:00-11:00 every Tuesday/Thursday,inspection can be arranged preferentially,shortening the waiting time by 2-3 days on average.
• The "Quick Handling Mechanism for Inspection Abnormalities" is newly added in 2026: In case of "document inconsistency",supplementary materials can be submitted through the "Single Window - Special Business" channel,and Zhongshitong coordinates with the customs for "1-hour response".

IV.2026 Import Declaration Risk List and Prevention and Control

Conclusion: In 2026,import customs declaration has shifted from "compliance release" to "value creation".Enterprises shall integrate "valuation pre-judgment,classification pre-review,risk pre-control" into the whole process,and achieve the import customs clearance goal of "safety,high efficiency and low cost" through the 20 years of port operation experience of professional agents.
