HTS heading 3202 is a broad product category for chemicals and preparations used in tanning hides and skins. It groups synthetic organic tanning substances, inorganic tanning substances, mixtures or preparations that may also contain natural tanning materials, and enzymatic preparations used for pre-tanning. The heading describes the product’s intended tanning function, not simply the fact that it is a chemical.
To narrow a product to an 8-digit HTS code, first confirm that its composition and use fit heading 3202. Then compare the product with the applicable subheading descriptions, which commonly distinguish products by material or type, such as synthetic organic substances, inorganic substances, tanning preparations, or enzymatic pre-tanning preparations. Review the full tariff wording and any legal notes; the correct code can depend on the ingredients, whether the product is a single substance or a formulated preparation, and its commercial presentation.
What to check
- Check the product’s technical data sheet, safety data sheet, ingredient list, and manufacturer description for its chemical identity and tanning function.
- Determine whether the item is a single tanning substance, an inorganic material, a formulated tanning preparation, or an enzyme-based pre-tanning product.
- Verify whether natural tanning substances are present and whether the product is supplied as a mixture, solution, concentrate, or other preparation.
- Compare the product’s composition and principal use with every relevant 8-digit subheading, not just the marketing name or a supplier’s suggested code.
- Ask a customs broker or seek a formal classification ruling when the formulation, intended use, or distinction between subheadings 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.
