U.S. imports of low-power transistors (non-photosensitive, under 1 watt dissipation) (HS 854121) totaled $20.7M in July 2026, traded with 36 countries.
Importers of Low-Power Transistors (Non-Photosensitive, Under 1 Watt Dissipation) paid $658K in duties in July 2026 — an effective duty rate of 49% on $1.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataTransistors with a dissipation rate below 1 watt — covering chips, dice, and wafers as well as finished devices — are further subdivided by operating frequency, with the 100 MHz boundary separating high-frequency RF transistors (8541210075) from lower-frequency general-purpose types (8541210095). Japan leads US imports under this heading, reflecting its deep expertise in precision analog and RF semiconductor fabrication. Frequency-based classification requires importers to reference manufacturer specifications carefully, as misclassification between the frequency-split lines is a common audit finding.

The US tariff schedule subdivides sub-1-watt transistors by whether their rated frequency is at or above 100 MHz (8541210075) or below 100 MHz (8541210095). This distinction reflects different end-use applications — RF and microwave circuits versus general switching and amplification — and the two lines may carry different duty treatment. The rated frequency on the manufacturer's datasheet is the controlling specification.
No. Unfinished chips, dice, and wafers for non-photosensitive transistors have their own dedicated line (8541210040) regardless of dissipation rate or frequency. Finished transistors are then classified into the frequency- and power-based lines. Importers shipping die-level product should confirm the stage of manufacture to avoid misclassification into a finished-device line.
