HTS heading 2826 is a broad product category for certain inorganic fluorine compounds. It groups fluorides, fluorosilicates, fluoroaluminates, and other complex fluorine salts—substances in which fluorine is combined with one or more other elements or ions. The heading covers a chemical family, not one universal product or duty treatment.
To reach the correct 8-digit HTSUS code, start with the product’s exact chemical identity and then follow the applicable subheading structure. Classification commonly narrows by the compound’s material or chemical type, such as whether it is a fluoride, fluorosilicate, fluoroaluminate, or another complex fluorine salt. Confirm the full 8-digit description, any unit-of-measure requirements, and the legal notes and exclusions that apply to the subheading.
What to check
- Obtain the product’s chemical name, formula, concentration, and CAS Registry Number from the supplier or technical documents.
- Determine whether the product is a single compound, a mixture, or a preparation; do not assume every fluorine-containing product belongs in heading 2826.
- Read the heading’s subheadings and compare the exact material description, including distinctions based on chemical type or composition.
- Check the HTSUS section and chapter notes, cross-references, and exclusions before accepting an 8-digit code.
- Keep the safety data sheet, certificate of analysis, product specification, and classification rationale; ask a customs broker or request a binding ruling if the chemistry is unclear.
HTS heading 2826 summary
Fluorides 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 2826?
Fluorides; fluorosilicates, fluoroaluminates and other complex fluorine salts. 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.
