HTS heading 2936 is a broad product category for provitamins and vitamins, whether naturally obtained or made by synthesis. It also covers natural vitamin concentrates, derivatives used primarily as vitamins, and mixtures of these products. The heading can include products presented in a solvent, so the presence of a carrier or solvent does not automatically move the product elsewhere.
To reach the correct 8-digit HTSUS code, first identify the product’s specific vitamin, provitamin, derivative, concentrate, or mixture. The subheadings generally separate products by their chemical identity or type, such as a particular vitamin or a group of related substances. Review the full product description, formulation, and applicable legal notes; an 8-digit classification may depend on whether the item is a single substance, a defined mixture, or another specified preparation.
What to check
- Identify the active substance precisely, using the chemical name, vitamin name, CAS information, and product specifications.
- Determine whether the item is natural, synthetic, a natural concentrate, a derivative used primarily as a vitamin, or an intermixture.
- Check the product’s complete formulation, including carriers, solvents, stabilizers, and other ingredients, rather than relying only on its trade name.
- Compare the wording of the relevant 8-digit subheadings and confirm that the product satisfies any stated composition or use conditions.
- Verify the classification against current official HTSUS material and obtain customs-broker or binding-ruling guidance when the chemistry, mixture, or intended use is uncertain.
HTS heading 2936 summary
Provitamins and vitamins is a 4-digit product category containing 9 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 2936?
Provitamins and vitamins, natural or reproduced by synthesis (including natural concentrates), derivatives thereof used primarily as vitamins, and intermixtures of the foregoing, whether or not in any solvent. 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.
