U.S. exports of Semiconductor Devices, NESOI (HS 854159) totaled $489.8M in August 2026.
Importers of Semiconductor Devices, NESOI paid $238K in duties in August 2026, an average duty rate of 0.13% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Semiconductor Devices, NESOI imports of $182.3M in August 2026 ran 55% above the year-to-date monthly average of $117.7M.
Last updated: August 2026 dataSemiconductor devices not elsewhere specified under HS 8541 are subject to Section 301 tariff exposure when sourced from certain origins, making classification precision critical for duty planning. The US schedule divides this heading into chips and wafers (8541590040) and other semiconductor devices (8541590080), a distinction that affects both duty treatment and export-control screening under Commerce Department rules. Israel and Ireland are the leading suppliers to the US market, with Taiwan a significant third source — a supply geography that reflects the global concentration of advanced fab and packaging capacity. Importers should verify whether specific device types fall under this heading or are more precisely classified under the integrated-circuit subheadings of Chapter 85.

The key distinction is functional integration: discrete semiconductor devices such as diodes, transistors, thyristors, and photosensitive devices classify under 8541, while monolithic or hybrid integrated circuits — where multiple circuit elements are formed on a single semiconductor body — classify under 8542. When a device combines both functions, CBP guidance and the Harmonized System Explanatory Notes should be consulted, and a binding ruling request may be warranted for novel or complex components.
Yes. The US tariff schedule explicitly separates chips and wafers for semiconductor devices (8541590040) from other semiconductor devices not elsewhere specified (8541590080). Unfinished wafers or die that have not yet been packaged into a discrete device may also warrant review under Chapter 85 notes to confirm the correct line.
