Product classification
HS code for Ignition module: 8511.80
Ignition or starting equipment, n.e.c. in heading no. 8511, of a kind used for spark or compression-ignition internal combustion engines.
Classification of ignition module under HS 8511.80
The ignition module is classified under HS code 8511.80 because it is an essential component of the electrical ignition or starting equipment used for spark-ignition or compression-ignition internal combustion engines. According to the General Rules of Interpretation (GRI) 1 and 6, products are classified based on the terms of the headings and subheadings. Heading 8511 specifically covers electrical ignition or starting equipment, including spark plugs, glow plugs, and ignition coils. The ignition module, which functions as an electronic switch to control the timing and distribution of the electrical pulse to the ignition coil, is a specialized automotive part. It does not have a more specific heading in the Harmonized System, and because it is dedicated to the engine's ignition cycle, it falls under the residual category of 8511.80 for other ignition equipment not elsewhere specified. This classification ensures that electronic control components specifically designed for engine starting and running are grouped with the mechanical and electrical hardware they manage.

Codes often confused with 8511.80
Common mistake. A frequent misclassification occurs with HS code 8537.10, which covers boards, panels, and other bases for electric control. While an ignition module does control electrical signals, 8511 is more specific to the engine's ignition function. Another common error is using HS code 9032.89 for automatic regulating or controlling instruments. However, Note 1 to Chapter 90 and the Explanatory Notes for 8511 clarify that electrical ignition equipment remains in Chapter 85 even if it performs a control function.
Top exporters and importers of HS 851180 (the code used for ignition module), 2025
In 2025, the largest exporter of HS 851180 (the code used for ignition module) in UN Comtrade data was Germany, with 21% of world exports; the largest importer in UN Comtrade data was Germany, with 18% 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 that did not report are estimated from what other countries recorded trading with them. 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).

Questions about ignition module
What is the HS code for Ignition module?
The HS code for Ignition module is 851180 (Ignition or starting equipment; n.e.c. in heading no. 8511, of a kind used for spark or compression-ignition internal combustion engines). The HS code for an ignition module used in internal combustion engines is 8511.80.
How do I classify Ignition module for customs?
Ignition module is classified under HS code 851180 — Ignition or starting equipment; n.e.c. in heading no. 8511, of a kind used for spark or compression-ignition internal combustion engines. This is a 6-digit subheading level code.
Can an ignition module be classified as a general-purpose integrated circuit?
No, an ignition module is an assembly of components designed for a specific automotive function. While it may contain integrated circuits, the complete module is classified as ignition equipment under 8511.80 rather than as an electronic integrated circuit under 8542.
Which countries are the top exporters of ignition module (HS 851180)?
In 2025, the top exporters of HS 851180 (the code used for ignition module) in UN Comtrade data were Germany ($230M, 21% of world exports), the United States ($181M) and China ($87M). World exports came to about $1.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
