2026 Full Process Guide to Industrial Raw Materials Import Customs Brokerage

Analysis of Core Links of Industrial Raw Materials Import Customs Brokerage in 2026Industrial raw materials import customs declaration involves multi-department collaboration.The newly issued Regulations on Import and Export Commodity Inspection Work at Shanghai Port in 2026 clearly requires enterprises to complete 3 pre-checks before customs declaration: certificate of origin verification,HS code pre-classification,and declaration element matching.As a Shanghai local customs brokerage enterprise,among the 127 industrial raw materials cases handled by Zhongshitong in the past six months,63% of the delays were caused by inconsistency between declaration elements and actual goods.The following breaks down practical operation points from three dimensions: customs supervision,commodity inspection and quarantine,and license application.### I.Customs Valuation and Accurate HS Code ClassificationThe 2026 customs valuation focuses on "transaction substance matching degree".A steel enterprise imported 1,000 tons of cold-rolled steel coils,which were declared as "other cold-rolled coils" under HS code 7209,but the actual material was special cold-rolled steel for automobiles that should be classified under HS code 7210.This resulted in the valuation department’s suspicion of "under-declaration of cargo value".Through Zhongshitong’s coordination,3 processing contracts were submitted for comparison with the customs valuation system.Finally,the applicable tax rate was confirmed to be reduced from 9.5% to 4.2%,saving RMB 210,000 in taxes.**Key Operations**:

• Submit pre-classification application 5 working days in advance (attached with product composition table and production process description)
• If the "brand" column in declaration elements is marked as "unlabeled",a third-party testing report shall be provided for certification
• High-risk categories (such as rare earths and hazardous chemicals) must fill in the "special supervision requirements" remark column### II.Commodity Inspection Pre-check and Animal and Plant Quarantine PrecautionsIn 2026,animal and plant quarantine added a new "biosafety level" label.A chemical enterprise’s imported palm oil was returned because it was not marked as "genetically modified or not".Zhongshitong coordinated with Zhejiang Commodity Inspection Bureau across regions to issue the "Non-GMO Certificate" on an expedited basis,and finally recovered the cargo loss.**Key Reminders**:<ul>- For raw materials involving wood,fur,etc.: the Entry Animal and Plant Quarantine Approval Document shall be attached (special categories need to apply 7 working days in advance)- Food contact materials: FDA or SGS testing report must be provided (the "heavy metal migration" standard is newly added in 2026)- Chemical raw materials: MSDS shall include the 2026 updated content of GHS classification (such as Category 2B carcinogen identification)In commodity inspection,3 types of goods are most likely to trigger "unpacking inspection":
  • The difference between declared weight and bill of lading weight is more than 5%
  • Package labels contain "dangerous goods" but are not declared separately
  • The certificate of origin is issued by an RCEP member state,but the "regional value content" item is not checked### III.Import License Application and Supervision Red LinesIn 2026,the Ministry of Commerce released the Catalogue of Dual-use Items for Import,adding that "part of graphite electrodes" need to apply for a separate license.Mr.Sun,a manager of a semiconductor enterprise,failed to complete the application 10 days in advance,resulting in 3 days of cargo detention after arrival at the port.Zhongshitong adopted the "dual-track declaration" mechanism: ① coordinate the chamber of commerce to issue the Pre-classification Judgment Letter; ② submit the license application simultaneously,and finally realize "cargo release upon arrival at the port".**Supervision Red Line List**:<ul>- Goods in the export control list (such as rare earths,tungsten ore): EXW trade term is prohibited,and the customs broker must complete the export customs declaration- Products in the 3C certification catalogue (such as industrial robots): complete domestic inspection 30 days in advance- Products subject to anti-dumping duties (such as Russian aluminum): the "country of origin" and "exporter filing number" must be marked in the remark column during declarationThe table below compares the responsibility division between enterprises and customs brokers under different trade terms:

### IV.Customs Clearance Fee and Hidden Risk ControlA chemical enterprise’s imported 500 tons of acrylate encountered a port demurrage dispute,which was finally resolved through Zhongshitong’s "three-lock mechanism": ① lock the shipping space (confirm 15 days in advance); ② lock the exchange rate (lock the exchange rate on the current day); ③ lock the inspection time (reserve a green channel appointment with the commodity inspection authority).The newly added "overdue storage fee" at ports in 2026 (RMB 0.8/ton/day) has a significant impact on bulk cargo,which requires special attention.**Risk Warning List**:
