HTS heading 2801 is a 4-digit product category for the chemical elements fluorine, chlorine, bromine, and iodine. It groups these halogens as products in their elemental form, rather than covering every product that merely contains one of them. The heading may include different presentations or types, which are separated at more detailed tariff levels.
To classify a shipment, start with the product’s actual chemical identity and condition, then move from heading 2801 to the applicable 6-digit subheading and finally the US-specific 8-digit tariff number. The more detailed code commonly distinguishes the element or material type. Review the HTSUS wording, unit of quantity, statistical suffix, and any applicable notes; a customs broker or classification specialist may be needed for unusual mixtures, solutions, compounds, or treated products.
What to check
- Confirm whether the merchandise is an elemental halogen covered by heading 2801, rather than a compound, mixture, solution, or product containing one of these elements.
- Check the product’s chemical name, formula, purity, physical form, concentration, and packaging against the technical description and safety data sheet.
- Read the complete 6-digit and 8-digit HTSUS descriptions, including any qualifiers, exclusions, unit-of-quantity requirements, and statistical suffix.
- Compare the classification with the product’s invoice, specification sheet, and import records so the declared description and code match.
- Seek customs-broker or professional advice when the product is a solution, blended material, laboratory preparation, or otherwise falls between headings.
HTS heading 2801 summary
Fluorine is a 4-digit product category containing 2 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 2801?
Fluorine, chlorine, bromine and iodine. 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.
