FAQ for this HTS code.

What is this HTS code?

This is a US Harmonized Tariff Schedule (HTS) code that classifies "Electrical ignition or starting equipment of a kind used for spark-ignition or compression-ignition internal combustion engines (for example, ignition magnetos, magneto-dynamos, ignition coils, spark plugs and glow plugs, starter motors); generators (for example, dynamos, alternators) and cut-outs of a kind used in conjunction with such engines; parts thereof:". It determines base duty rates for imports; additional duties may apply by country of origin.

Does origin affect duty?

Yes. General and Special rates apply by trade agreement and origin. Additional duties (Section 301, 232, IEEPA) are origin-specific. Use the tariff calculator or resolve API with an origin to see full duty.

How do I compute total duty?

Use our tariff calculator (with HTS and optional origin) or the API endpoint GET /api/v1/tariffs/resolve with hts and origin. The API returns base tariffs and additional measures separately; sum as needed for your use case.

Tariff data is informational; final determinations are made by CBP.
