HTS heading 2908 is a broad product category for chemical derivatives made from phenols or phenol-alcohols. It covers those base chemicals after a hydrogen atom in the molecule has been replaced or modified by a halogen group, sulfonic group, nitro group, or nitroso group. In simple terms, the heading groups certain chemically modified phenol compounds, not ordinary finished goods that merely contain a phenol-based ingredient.
The 4-digit heading is only the starting point. To select an 8-digit HTSUS code, follow the subheadings and product descriptions, which commonly distinguish the compound by its chemical identity, derivative type, or other stated characteristics. Confirm the product’s exact molecular name, composition, and form against the applicable subheading language; classification may require a customs broker, chemist, or binding ruling when the chemistry or tariff wording is unclear.
What to check
- Obtain the exact chemical name, molecular formula, CAS Registry Number, and specification sheet for the imported product.
- Determine whether the compound is a halogenated, sulfonated, nitrated, or nitrosated derivative of a phenol or phenol-alcohol, rather than a mixture or a different chemical class.
- Read every level of the HTSUS hierarchy below heading 2908 and match the product to the most specific description based on its chemical identity or type.
- Check whether the product is a pure compound, solution, mixture, preparation, or formulated product; its physical form and composition can affect classification.
- Compare the proposed code with CBP rulings, the tariff’s legal notes, and current official HTSUS text, and seek broker or specialist advice if no description clearly fits.
HTS heading 2908 summary
Halogenated 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 2908?
Halogenated, sulfonated, nitrated or nitrosated derivatives of phenols or phenol-alcohols. 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.
