HTS heading 7322 is a 4-digit product category for certain non-electric heating and air-distribution equipment made of iron or steel. It groups together two broad types of goods: radiators used in central-heating systems, and air heaters or hot-air distributors that use a motor-driven fan or blower. It also covers qualifying parts of those products.
To choose the correct 8-digit HTSUS code, first identify which product family applies, then use the more detailed description under that heading. The tariff may distinguish items by their construction, function, or material and may separate complete equipment from parts. Confirm the product’s essential characteristics, rather than choosing based only on its name or how it is marketed.
What to check
- Determine whether the item is a central-heating radiator, a fan-assisted air heater or hot-air distributor, or a part for one of those products.
- Verify that the equipment is not electrically heated; a motor-driven fan or blower can be present, but the heating function must fit the heading’s description.
- Confirm the main material and construction, including whether the relevant item is of iron or steel and whether any other material changes its classification.
- For parts, check whether the item is identifiable as a part designed for the covered radiator or air-heating equipment, rather than a general-purpose component.
- Compare the full product specifications, drawings, and manufacturer information with the current 8-digit HTSUS wording; ask a customs broker or classification specialist when the product has multiple functions or borderline features.

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.
