HTS heading 2901 is a 4-digit category in Chapter 29 for acyclic hydrocarbons—organic chemical substances made only of carbon and hydrogen whose atoms are arranged in open chains rather than rings. It generally groups substances such as saturated hydrocarbons and unsaturated hydrocarbons, including products distinguished by their particular chemical identity.
To reach a specific 8-digit US HTS code, first identify the product’s internationally recognized chemical name and structure. The classification usually narrows by the type of hydrocarbon and the individual compound or product description. The first six digits generally reflect the global Harmonized System, while the additional US digits provide more detailed statistical distinctions. Confirm that the product belongs in heading 2901 rather than another heading covering mixtures, preparations, petroleum products, or a different chemical class.
What to check
- Obtain the product’s exact chemical name, CAS Registry Number, molecular formula, and structural information from the safety data sheet or technical specification.
- Determine whether the substance is saturated or unsaturated and whether it is a single chemically defined compound or a mixture.
- Compare the product’s composition, concentration, and physical form with the wording of the relevant 8-digit HTS provisions and their legal notes.
- Check the current US HTS, including chapter and section notes, because similar hydrocarbons may be classified differently depending on composition or presentation.
- Request a customs-broker review or a binding classification ruling when the chemical identity, purity, mixture status, or intended use creates uncertainty.
HTS heading 2901 summary
Acyclic hydrocarbons is a 4-digit product category containing 0 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 2901?
Acyclic hydrocarbons. 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.
