Product classification
HS code for Automotive wiring harness: 8544.30
Insulated electric conductors, ignition wiring sets and other wiring sets of a kind used in vehicles, aircraft or ships.
Classification of automotive wiring harness under HS 8544.30
The automotive wiring harness is classified under HS code 8544.30. This code is situated within Chapter 85, which covers electrical machinery and equipment. Heading 8544 specifically addresses insulated electric conductors, including wire, cable, and other conductors, whether or not fitted with connectors. Subheading 8544.30 is a specific provision for ignition wiring sets and other wiring sets of a kind used in vehicles, aircraft, or ships. These harnesses are complex assemblies of wires, terminals, and connectors designed to transmit electrical power and signals throughout a vehicle. The classification is driven by the function of the product as an electrical conductor assembly specifically configured for vehicular use. Under the Harmonized System, products that are specifically named in a heading or subheading, such as "wiring sets of a kind used in vehicles," must be classified there rather than under more general headings for vehicle parts.

Codes often confused with 8544.30
Common mistake. Automotive wiring harnesses are often incorrectly classified under HS code 8708.99 (Parts and accessories of motor vehicles). While they are essential components of a vehicle, the specific provision in 8544.30 for "wiring sets" takes precedence over the general parts heading in Chapter 87. Additionally, some may attempt to use 8544.42 (Other electric conductors for a voltage not exceeding 1,000 V), but this is only appropriate for individual wires or cables that do not constitute a specific "set" or harness designed for a vehicle.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
