HTS heading 8479 is a broad category for machines and mechanical appliances that perform an individual function but are not more specifically described in another heading of Chapter 84. Examples may include specialized machinery, processing equipment, or mechanical appliances whose main function does not fit a more specific machinery category. The heading can also cover parts of those machines when the parts meet the applicable classification rules.
To reach the correct 8-digit HTSUS code, first confirm that heading 8479 is appropriate rather than a more specific heading elsewhere in Chapter 84 or another chapter. Then follow the subheading structure: the 6-digit level identifies the international product grouping, while the additional U.S. digits provide more detailed statistical distinctions. Those distinctions may be based on the machine's function, design, use, construction, or other stated characteristics—not necessarily only its material or type. Read the complete description, including legal notes and any “other” provisions, and classify the actual machine or part as imported.
What to check
- Describe the machine's principal function, operating method, and intended use before searching the tariff.
- Check whether another HTS heading specifically names the machine; heading 8479 is generally a residual, or “not elsewhere specified,” category.
- Compare the product's physical design, components, capacity, and application with every relevant 8-digit subheading description.
- For a part, confirm whether it is identifiable as being solely or principally used with a machine covered by heading 8479 and review the applicable parts provisions.
- Verify the current HTSUS text, chapter and section notes, Customs rulings, and broker guidance; obtain a binding classification ruling when the choice is uncertain.
HTS heading 8479 summary
Machines and mechanical appliances having individual is a 4-digit product category containing 6 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 8479?

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.
