I. Wire Harness Automotive PartsImport ClearanceThe core challenge

1.Commodity classification risks
The harness (Harness) should determine the HS code based on material, purpose, connected components, etc. For example:

• Wire harnesses for vehicle electrical systems (such as engine harnesses, body harnesses) are generally classified underUnder heading 8544.30.(Wiring harness for vehicles);
• If the product includes components such as connectors or terminals, it may fall under other tariff headings (e.g., 8536, 8537), and a comprehensive determination should be made based on the actual function of the item.
  Note: Incorrect classification may result in tariff discrepancies (e.g., general tariff rate vs. agreement tariff rate) and subsequent audit risks.

2.Access and Compliance Requirements

• 3CIt is recommended to compare the following transportation methods:: Some wiring harness products require compliance with China's Compulsory Certification (3C), so it is necessary to confirm in advance whether they are included in the catalog;
• Energy Efficiency and Environmental Protection Standards: The insulation materials and heavy metal content involved must comply with standards such as GB/T 25085 and GB/T 25087;
• It is recommended to verify through the following methods:Certificate: To enjoy preferential tariff rates under free trade agreements (such as RCEP or the China-Korea FTA), a valid certificate of origin must be provided.

3.The latest tax rebate declaration system in 2025 has achieved full - process electronicization, which is specifically divided into five steps:
Required documents to prepare: Proforma invoice, packing list, bill of lading, import contract, certificate of origin, test report (such as flame retardancy test), instruction manual (including technical parameters), etc.

II. Breakdown of the Entire Process for Wire Harness Import Agency Customs Clearance

Pre - preparation Stage

• Qualification Filing: Confirm that the importer possessesimport and exportComplete the customs consignee and consignor registration;
• Technical pre-review: Review whether the product complies with Chinese standards and arrange third-party testing if necessary;
• Pre - classification ruling: For new models or complex wiring harnesses, a pre-classification ruling can be applied for with customs to reduce risks.

2. Declaration of goods upon arrival at port

• Declaration elements: It is necessary to clarify the material of the wiring harness (such as copper core, aluminum core), its purpose (applicable vehicle model/system), voltage/current parameters, etc.;
• Standardized Declaration Examples:
  "Vehicle wiring harness, material: copper-core insulated wire, rated voltage 60V, used for the engine control system of XX brand fuel vehicles."

3. Customs Inspection and Release

• Key inspection items:
  • Does the physical item match the declaration (e.g., model, brand);
  • Does the label and instruction manual contain Chinese markings;
  • Are there any undeclared accessories (such as included sensors, plugs)?
• Fast clearance strategy:

Question 1: What should be done if the wiring harness is questioned by customs for incorrect classification?

• Solution: Provide product design drawings, technical parameters, and physical photos, and explain to customs in conjunction with the "Notes" and classification decision letters; apply for reclassification if necessary.

Question 2: Are testing reports provided by foreign entities not recognized by China Customs?

• Solution: Confirm in advance whether the testing institution has CNAS accreditation, or commission a domestic laboratory to conduct supplementary testing.
