HTS heading 2902 is a four-digit product category for cyclic hydrocarbons. These are hydrocarbons whose carbon atoms form one or more rings, rather than existing only as open chains. The heading can cover different kinds of ring-structured chemicals, including aromatic and non-aromatic types, depending on their chemical structure.
To reach the correct eight-digit HTSUS code, narrow the product by its exact chemical identity and the more specific subheading description. Check whether it is a single chemically defined compound or a mixture, identify its ring structure and any relevant substituents, and confirm the product’s form and composition. The eight-digit code—not the four-digit heading alone—controls the detailed tariff treatment, so classification may require a customs broker or other qualified professional.
What to check
- Obtain the product’s exact chemical name, CAS Registry Number, molecular formula, and composition from the safety data sheet and supplier specifications.
- Determine whether the shipment is a single compound, an isomer or defined group of isomers, or a mixture; do not classify by a trade name alone.
- Read the HTSUS subheading text and relevant chapter notes to match the material’s chemical structure and any stated purity or composition requirements.
- Compare the product description, SDS, technical data, and commercial invoice so they all support the same classification.
- Confirm the proposed eight-digit code with current official HTSUS materials or a qualified customs broker, especially when the substance is blended, specially prepared, or chemically modified.
HTS heading 2902 summary
Cyclic hydrocarbons is a 4-digit product category containing 7 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 2902?
Cyclic 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.
