HTS heading 7901 is a four-digit product category for unwrought zinc. “Unwrought” generally means zinc in a primary or semi-finished form—such as metal supplied as ingots, slabs, blocks, billets, or similar forms—rather than worked into articles, parts, wire, sheets, or other finished products. The heading can group both zinc that is not alloyed and certain zinc alloys, depending on the product’s composition and form.
To reach the correct eight-digit US HTS code, first confirm that the merchandise is actually unwrought zinc and belongs in heading 7901 rather than a heading for worked zinc or zinc articles. Then use the relevant subheading and statistical suffix, which commonly distinguish the material or type—such as unalloyed zinc versus zinc alloys and any further product-specific description. The product’s chemical composition, physical form, and documentation control the classification; the heading alone is not enough to determine the final code.
What to check
- Verify the product is unwrought zinc, not sheet, wire, powder, scrap, a zinc article, or another worked form.
- Obtain the supplier’s technical specification or assay showing zinc content and the presence and levels of alloying elements.
- Match the physical form and commercial description to the wording of the applicable eight-digit subheading and statistical suffix.
- Check the country-specific US HTS edition in effect for the entry date, including any additional notes or applicable measures.
- Ask a customs broker or classification specialist to review borderline cases, especially where composition or processing is unclear.

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 7901?
Unwrought zinc. 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?
