HTS heading 8417 is a broad product category for nonelectric industrial or laboratory furnaces and ovens, including incinerators, and their parts. It generally covers equipment that uses a fuel or another nonelectric heat source for controlled high-temperature processing, rather than ordinary household or electric heating appliances.
To reach the correct 8-digit HTSUS code, first confirm that the product belongs in heading 8417 and is nonelectric. Then read the lower-level subheadings, which commonly distinguish equipment by function, construction, or the material being processed, and separately identify parts when the item is not a complete furnace or oven. The product’s design and principal use—not just its marketing name—usually control classification.
What to check
- Confirm whether the equipment is genuinely nonelectric for customs purposes; an electric heating element or electric primary heat source may place it elsewhere.
- Identify the equipment’s specific function, such as industrial heating, laboratory processing, or incineration, and document its intended use.
- Check the subheading descriptions for distinctions based on furnace or oven type, construction, capacity, or material processed; use the product’s technical specifications rather than a catalog label alone.
- For a part, determine whether it is identifiable for use with the covered equipment and whether the tariff schedule provides a specific parts provision.
- Compare the complete product configuration, manuals, drawings, and commercial invoice description with current HTSUS text, and seek a customs broker or binding ruling when classification is uncertain.
HTS heading 8417 summary
Industrial or laboratory furnaces and ovens 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.
