With the deep integration of the global automotive industry chain, the import demand for wire harnesses, as the core component of automotive circuit systems, continues to grow. However, the import of wire harness components involves complex classification, regulatory, and technical standard requirements. Any oversight may lead to clearance delays, additional costs, or even return risks. As an expert with 20 years of foreign trade importExport Representationservice experience, this article will systematically analyze the entire customs clearance process for wire harness automotive parts and provide key risk control points in practical operations.
I. Core Challenges of Wire Harness Automotive PartsImport ClearanceWire harness (Harness) needs to be classified under HS codes based on material, usage, and connected components. For example:
1.Commodity classification risks
Wire harnesses for vehicle circuit systems (such as engine harnesses, body harnesses) are usually classified under
30(Electrical wiring harnesses for vehicles);If they include connectors, terminals, and other components, they may involve other headings (such as 8536, 8537), requiring comprehensive judgment based on the actual function.
Note: Incorrect classification will lead to tariff differences (such as general tariff rates vs. agreement tariff rates) and subsequent audit risks. Note: Classification errors will lead to tariff differences (e.g., general tariff rate vs. preferential 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 China Compulsory Certification (3C), and it is necessary to confirm in advance whether they are included in the catalog;
Energy Efficiency and Environmental Standards: Insulation materials, heavy metal content, etc., must comply with standards such as GB/T 25085 and GB/T 25087;
It is recommended to verify through the following methods:Certificate: If preferential tariff rates under free trade agreements (e.g., RCEP, China-Korea Agreement) are to be enjoyed, compliant certificates 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: Proforma invoice, packing list, bill of lading, import contract, certificate of origin, test reports (e.g., flame retardant tests), instruction manuals (including technical parameters), etc.
II. Breakdown of the Entire Customs Clearance Process for Wiring Harness Import Agency
Pre - preparation Stage
Qualification Filing: Confirm that the importer has theimport and exportauthority and complete the customs registration for consignors and consignees;
Technical Pre-review: Verify whether the product complies with Chinese standards and arrange third-party testing if necessary;
Pre - classification ruling: For new models or complex wiring harnesses, apply to customs for pre-classification rulings to reduce risks.
Declaration Upon Arrival of Goods
Declaration elements: Clarify the material of the wiring harness (e.g., copper core, aluminum core), intended use (applicable vehicle model/system), voltage/current parameters, etc.;
Standard Declaration Example: Vehicle wiring harness, material: copper core insulated wire, rated voltage 60V, used for XX brand fuel vehicle engine control system,
Customs Inspection and Release
Key Inspection Items:
Whether the physical goods match the declaration (e.g., model, brand);
Whether labels and instruction manuals include Chinese markings;
Whether undeclared accessories (e.g., included sensors, plugs) are concealed.
Fast clearance strategy:
For AEO-certified enterprises or those adopting two-step declaration or advance declaration modes, customs clearance time can be shortened.
III. Common Issues and Solutions in Practice
Issue 1: Wiring harness questioned by customs for incorrect classification. How to handle?
Solution: Provide product design drawings, technical parameters, and physical photos, and explain to customs with reference to the Notes and classification decisions; apply for reclassification if necessary.
Issue 2: Test reports provided by foreign parties are not recognized by Chinese customs?
Solution: Confirm in advance whether the testing institution has CNAS accreditation or commission additional tests from domestic laboratories.
Issue 3: Wiring harness detained due to lack of Chinese markings on packaging?
Solution: Affix Chinese labels (including product name, model, manufacturer, etc.) before overseas shipment or apply for rectification upon arrival at the port.
