HTS heading 2926 is a four-digit product category for nitrile-function compounds. In general, it groups organic chemical products that contain a nitrile functional group—a carbon-based chemical structure containing a carbon atom bonded to nitrogen by a triple bond. The heading can cover different chemical substances and mixtures, but the exact scope depends on the tariff provisions and any exclusions or notes.
To narrow heading 2926 to an eight-digit HTSUS code, identify the specific substance and follow the subheading structure. The lower-level provisions commonly distinguish products by their chemical identity, type, or material composition. Use the product’s chemical name, formula, CAS Registry Number, purity, formulation, and intended use as evidence; do not select a code based only on a trade name or the word “nitrile.” Confirm the current eight-digit provision and any applicable statistical suffix in the official HTSUS, and seek a customs broker or binding ruling when the chemistry or classification is unclear.
What to check
- Obtain the full chemical identity, including the systematic name, formula, CAS Registry Number, and concentration or purity.
- Check whether the item is a single chemically defined compound, a mixture, solution, preparation, or formulated product; that distinction can change classification.
- Read the heading, subheading text, section and chapter notes, and any relevant exclusions before choosing the eight-digit code.
- Compare the product’s actual composition with the descriptions at each level; do not rely only on the supplier’s suggested HTS code or marketing name.
- Keep technical data sheets, safety data sheets, specifications, and laboratory information to support the classification, and ask a customs professional about difficult cases.
HTS heading 2926 summary
Nitrile-function compounds is a 4-digit product category containing 3 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 2926?
Nitrile-function compounds. 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.
