HTS heading 2813 is a four-digit product category for certain inorganic chemical compounds: sulfides of nonmetals, along with commercial phosphorus trisulfide. In plain language, it groups sulfur compounds made with nonmetal elements and a specifically named commercial phosphorus compound. The heading is a starting point, not usually the complete classification for entry purposes.
To reach the correct 8-digit HTS code, first confirm that the product legally belongs in heading 2813, then follow the subheading structure and any applicable statistical subdivisions. The narrower code may depend on the chemical identity, such as the nonmetal combined with sulfur, whether the product is phosphorus trisulfide, and sometimes the product’s form or other tariff-defined distinctions. Use the product’s exact composition and the HTS wording—not its trade name alone—to make the selection.
What to check
- Obtain the chemical name, formula, concentration or purity, and CAS Registry Number from the safety data sheet, specification sheet, or supplier.
- Check the HTS hierarchy from heading 2813 through each subheading and 8-digit statistical suffix; do not stop at the four-digit heading.
- Distinguish phosphorus trisulfide from other nonmetal sulfides and verify whether the tariff text uses a specific chemical or product description.
- Confirm whether the imported material is a pure compound, mixture, solution, preparation, or formulated product, because that may affect classification.
- Request a customs broker’s review or a binding ruling when the composition, product form, or competing HTS provisions create uncertainty.

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 2813?
Sulfides of nonmetals; commercial phosphorus trisulfide. 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?
