2026 Shanghai Import Customs Clearance Full Process Compliance Guide

I.Customs Valuation: Full-Link Risk Control from Code Classification to Price Verification

In 2026,the "global supply chain data linkage verification" mechanism is added to the customs valuation rules.Enterprises are required to submit 8 types of core documents simultaneously when declaring,including certificate of origin,purchase contract,bill of lading,etc.Take an electronic enterprise importing precision instruments as an example: it mistakenly wrote the 10-digit HS code as 8 digits,which led the customs to classify the goods as "incompletely declared".The single shipment was detained in the inspection area for 14 days,incurring storage fees of 23,000 CNY.

1.Accurate HS Code Classification Logic

• It is necessary to strictly match the cross annotations of Chapter 4 "Mechanical and Electrical Products" and Chapter 17 "Special Purpose Equipment" in the 2026 Customs Commodity Classification Compilation,to avoid confusion between "general-purpose" and "special-purpose" equipment.For example,the tax rate difference between medical CT scanners (854370) and industrial CT scanners (844330) reaches 300%.
• Technical parameters shall be indicated in the "Remarks Column" when declaring,such as "weight 150kg/unit,power 3000W,voltage 220V".The customs classification system will automatically compare the "weight threshold" and "function description" in the tariff annotation to determine whether the tax rate application conditions are met.

2.Compliance Verification of Declared Value

Customs will focus on verifying three types of price anomalies in 2026: ① The deviation between the declared price and the average import price in the same period exceeds 20% (a third-party valuation report is required); ② Freight and insurance premiums are not included in the FOB price (insurance policy and freight allocation agreement shall be supplemented); ③ A "non-controlled relationship declaration" shall be provided for related party transaction prices.A European auto parts supplier had its declared price 15% lower than historical import data,so the customs launched a retrospective review using the transaction value method.Finally,the tax was recalculated according to the "2026 Industry Benchmark Price" issued by the General Administration of Customs,with a supplementary tax payment of 470,000 CNY.

II.Commodity Inspection Pre-Check: Avoid Quarantine Risks in Advance

After the revision of the Law on Import and Export Commodity Inspection in 2026,a dual-track system of "negative list + localized inspection" is implemented for animal and plant quarantine.A US soybean importer failed to apply for the "Entry Plant Quarantine Approval Form" in advance,resulting in mandatory return of goods after arrival at the port,incurring return costs of 86,000 USD.

1.Pre-Check Differences between General Cargo and Special Categories

2.Quarantine Risk Early Warning List

• Wooden packaging without IPPC marking: supplementary marking is required after arrival at port,with a fine of 2,000 CNY per case
• Cosmetics without indicating the "2026 Cosmetic Filing Number": Customs impose a fine of 50% of the cargo value for "import without certificate"
• Medical devices without submitting the "Import Medical Device Registration Certificate": directly trigger "no release" and require return of goods

III.Import License Processing: Category-based Access Rules

In 2026,12 categories of commodities such as rare earth products and military-related products are added to require additional application for "dual-use items import license".A rare earth permanent magnet enterprise was detained by Shanghai Customs for 5 days due to omission of the license,and missed the order for an international exhibition.

1.Four-Step Process for License Application

• Submit the Import License Application Form on the "Single Window" (the "end use" shall be filled in: industrial/scientific research/civil use)
• Submit "enterprise production qualification certificate" (the "ISO 14001 environmental management system certification requirement added in 2026)
• Wait 3 working days for pre-check,and "end user statement from the exporting country government" shall be supplemented for dual-use items
• Associate the "license number" when declaring at the port with the electronic license,failure to associate will trigger a return order for "invalid license"

2.Supervision Red Lines for Special Categories

• Used equipment: "service life declaration" (≤8 years) and "non-radiation test report" (new requirement added in 2026) shall be submitted
• Luxury goods: "brand authorization letter number" shall be indicated when declaring,and Customs will verify the integrity of the authorization chain
• Cross-border e-commerce retail import: declaration shall be made through the dual track of "personal article postal tax" and "goods trade".The "list-based management" is piloted in 2026,and commodities beyond the list shall pay supplementary tax according to the goods tax category

IV.2026 Customs Clearance Risk Prevention and Control System

Typical risk case: A chemical enterprise imported 1,000 tons of polycarbonate,failed to submit the "certificate of origin + customs duty payment certificate of the exporting country" when declaring,which led the customs to identify it as "non-origin country" and apply 15% anti-dumping duty (the applicable tax rate for the country of origin is 5%).After Zhongshitong resubmitted the materials,the origin rule verification was completed in 3 working days,and the 5% tax rate was restored,saving 870,000 CNY in tariff losses.

Core prevention and control suggestions: ① Establish a "double valuation team": enterprise preliminary review + agency recheck to avoid single errors; ② Retain "365-day data files": including historical customs declaration forms,inspection records,tax rate adjustment notices,to provide compliance reference for imports in the next quarter; ③ Activate the "customs pre-classification" service on the "Single Window" to obtain the code determination result 72 hours in advance.
