Short answer
What HS code 854121 means before paying a 1688 supplier
HS code 854121 is the 6-digit HS 2022 starting point for small signal transistor; often searched as small signal transistor, low power transistor, transistor. Before using it in a landed-cost estimate, confirm the product material, function, destination market, and the official tariff source. Treat any 1688 supplier code as a clue, not the final import classification.
Use
Start with this 6-digit HS code and compare the product's material, function, and use.
Verify
Check the destination market's official HTS, TARIC, commodity-code, duty, VAT, or GST source.
Decide
If classification, documents, or restricted-product risk is unclear, submit the product for a written check.
Covered products
What products fall under HS code 854121?
Buyers sourcing with a dissipation rate of less than 1 w from 1688 commonly describe it in these ways. If your product matches, 854121 is likely the right 6-digit starting point — confirm material and intended use against the official tariff.
Import duty by market
Where to check the import duty for HS 854121
The 6-digit code is universal, but duty, VAT and GST are set by the destination country and depend on the full national tariff line with China as the country of origin. Start from the official source for your market.

Heading 8541
Other HS codes under 8541
Subheadings in the same 4-digit heading — "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". If 854121 is not an exact match, one of these may classify your product more precisely.
Questions
HS code 854121: common questions
What is 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.
What products fall under HS 854121?
Common products classified under 854121 include small signal transistor, low power transistor, transistor, 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.
How do I find the import duty for HS code 854121?
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.
Is HS code 854121 the same in every country?
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.
Can I trust the HS code a 1688 supplier gives me?
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.
