Semiconductor devices — HTS 8541
Semiconductor devices (for example, diodes, transistors, semiconductor-based transducers); photosensitive semiconductor devices, including photovoltaic cells whether or not assembled in modules or made up into panels; light-emitting diodes (LED), whether or not assembled with other light-emitting diodes (LED); mounted piezo-electric crystals; parts thereof

HTS heading 8541 is a broad product category for semiconductor components and certain related parts. It includes devices such as diodes, transistors, semiconductor-based transducers, photosensitive semiconductor devices, photovoltaic cells, LEDs, and mounted piezo-electric crystals. It can cover an individual component or, where the tariff description allows, components assembled into modules or panels.
To reach the correct 8-digit HTSUS code, start with the heading and then follow the more specific subheadings and statistical breakouts. The distinguishing facts often include the device’s technical type, semiconductor material or construction, photosensitive or photovoltaic function, whether it is an LED, whether it is mounted or assembled, and whether it is a part rather than a complete device. The product’s commercial name alone is usually not enough; classification may require technical specifications and professional customs judgment.
What to check
- Identify the device’s primary function and physical technology, such as diode, transistor, transducer, photovoltaic cell, LED, or piezo-electric crystal.
- Check the exact subheading wording for distinctions involving material, construction, photosensitivity, photovoltaic use, mounting, assembly, or parts.
- Confirm whether the item is a complete device, a component assembled into a module or panel, or a dedicated part of another device.
- Compare the tariff description with datasheets, drawings, invoices, and product samples; do not rely only on a marketing name or catalog category.
- Document the classification reasoning and seek a customs broker or binding ruling when the specifications fit more than one possible 8-digit code.
HTS heading 8541 summary
Semiconductor devices is a 4-digit product category containing 4 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.

Common questions
What products fall under HTS heading 8541?
Semiconductor devices (for example, diodes, transistors, semiconductor-based transducers); photosensitive semiconductor devices, including photovoltaic cells whether or not assembled in modules or made up into panels; light-emitting diodes (LED), whether or not assembled with other light-emitting diodes (LED); mounted piezo-electric crystals; parts thereof. To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
Start from the sub-categories (typically divided by material—for example cotton versus man-made fibers), then open the active 8- or 10-digit code that matches the product. When unsure, a licensed customs broker or a CBP binding ruling can confirm the classification.
