HTS heading 8542 is a broad product category for electronic integrated circuits and parts of those circuits. It generally groups semiconductor devices in which multiple electronic elements—such as transistors, diodes, or other circuit functions—are integrated onto a semiconductor material or into a combined electronic assembly. The heading can cover finished integrated circuits as well as certain identifiable parts, depending on the product’s design and the HTS wording.
A 4-digit heading is only the starting point. To reach the correct 8-digit HTS code, first identify what the item is and does, then follow the more specific subheadings and statistical subdivisions. Those subdivisions may distinguish products by type, function, construction, or material—for example, whether the item is a memory, processor, amplifier, or other integrated circuit, and whether it is presented as a separate part. Read the complete 8-digit description and confirm that it matches the physical product, not just its marketing name.
What to check
- Identify the circuit’s principal function, such as processing, memory, amplification, control, or another specified function, using the datasheet and technical specifications.
- Check whether the product is a complete integrated circuit, an identifiable part, or a different semiconductor device that may belong in another heading.
- Review the subheading language for distinctions based on circuit type, construction, material, packaging, or other stated characteristics.
- Compare the manufacturer’s part number, datasheet, photographs, and packaging with the full 8-digit HTS description; do not rely on a catalog label alone.
- Confirm the classification with current official HTS materials and, when the facts are unusual or the consequences are significant, seek a customs broker or binding classification ruling.
HTS heading 8542 summary
Electronic integrated circuits is a 4-digit product category containing 5 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 8542?
Electronic integrated circuits; 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.
