Product classification
HS code for Ignition wire set: 8544.30
Insulated electric conductors, ignition wiring sets and other wiring sets of a kind used in vehicles, aircraft or ships.
Classification of ignition wire set under HS 8544.30
Ignition wiring sets are classified under HS code 854430 because they consist of insulated electric conductors specifically designed and bundled for use in vehicles, aircraft, or ships. Heading 8544 covers insulated wire, cable, and other insulated electric conductors. Subheading 854430 is a specific provision for ignition wiring sets and other wiring sets of a kind used in vehicles. The classification is driven by the fact that these are not merely bulk wires but are prepared assemblies, often with connectors, boots, or terminals attached, tailored for the high-voltage requirements of an internal combustion engine ignition system. The insulation must be capable of withstanding high temperatures, oil, and electrical stress, which is a defining characteristic of products in this category. Under GRI 1, the specific mention of ignition wiring sets in the nomenclature for 854430 dictates its use over more general wire categories. These sets are vital for transmitting the high-voltage current from the ignition coil or magneto to the spark plugs without leakage or interference.

Codes often confused with 8544.30
Common mistake. These sets are often misclassified under HS code 854442, which covers other electric conductors fitted with connectors. However, 854430 is the more specific code for vehicle-specific wiring. Another common mistake is attempting to classify them under HS code 8708 as general parts of motor vehicles. According to the Section XVI notes, electrical machinery and parts thereof are generally excluded from Section XVII (Vehicles) and must be classified in Chapter 85.
Top exporters and importers of HS 854430 (the code used for ignition wire set), 2025
In 2025, the largest exporter of HS 854430 (the code used for ignition wire set) in UN Comtrade data was Mexico, with 18% of world exports; the largest importer in UN Comtrade data was the United States, with 28% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
