HS Code 854121

HS code 854121 is the World Customs Organization 6-digit HS 2022 subheading for "Diodes, transistors and similar semiconductor devices; photosensitive semiconductor devices, including photovoltaic cells whether or not assembled in modules or made up into panels; lightemitting diodes (LED); mounted piezoelectric crystals : Transistors, other than photosensitive transistors : With a dissipation rate of less than 1 W". The first two digits (85) are the chapter — Electrical machinery and equipment; sound and TV recorders and reproducers — and digits 3-4 (8541) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 854121 include small signal transistor, low power transistor, transistor, BJT, MOSFET and similar items matching with a dissipation rate of less than 1 w. The correct code still depends on the product's material, function and intended use.

Duty is set by the destination country, not by the 6-digit HS code alone. Start from the official tariff of your market — USITC HTS (US), TARIC / Access2Markets (EU), GOV.UK Trade Tariff (UK), CBSA (Canada), ABF (Australia) or Singapore Customs — and look up the full national code with China as the country of origin.

The first 6 digits (854121) are the same worldwide under the WCO Harmonized System. Beyond that, each country extends the code (HTS in the US, TARIC in the EU, etc.) and sets its own duty and tax rates.

Treat a supplier-provided code as a clue, not a final classification. It can be incomplete, China-export-specific, or mismatched to your destination's rules. Verify against the official tariff and your product's actual material and use.
