HTS heading 8514 is a broad product category for certain industrial or laboratory equipment that heats materials using electricity. It includes electric furnaces and ovens, including induction and dielectric-heating equipment, as well as other industrial or laboratory equipment used to heat-treat materials by induction or dielectric loss. The heading can also cover parts of that equipment when the tariff structure provides for them.
A merchant narrows the heading to a specific 8-digit HTSUS code by identifying the equipment’s function, heating method, and construction or intended use. The lower-level subheadings commonly distinguish among equipment types—such as furnaces, ovens, induction equipment, dielectric-loss equipment, or parts—and may further separate products by material, design, or other technical characteristics. Read the complete tariff description and the relevant notes, not just the first words of the heading.
What to check
- Confirm that the equipment is industrial or laboratory equipment and that its primary function is electric heating or heat treatment.
- Identify the heating method: resistance, induction, dielectric loss, or another method, and compare it with the wording of the applicable subheadings.
- Determine whether the shipment is a complete machine, a dedicated part, or a general-purpose component that may belong elsewhere.
- Review the product’s technical specifications, operating principle, capacity, and intended material treatment; do not classify from the marketing name alone.
- Check the current HTSUS text, section and chapter notes, and any binding ruling or customs-broker advice relevant to the product.
HTS heading 8514 summary
Industrial or laboratory electric furnaces and ovens is a 4-digit product category containing 3 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 8514?
Industrial or laboratory electric furnaces and ovens (including those functioning by induction or dielectric loss); other industrial or laboratory equipment for the heat treatment of materials by induction or dielectric loss; 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.
