HTS heading 2844 is a broad product category for radioactive chemical elements and radioactive isotopes, including fissile or fertile materials, along with their compounds. It also covers mixtures and residues that contain these radioactive products. In practice, this heading groups materials by what they are made of and their radioactive or nuclear characteristics, rather than by ordinary commercial product names alone.
To reach a specific 8-digit HTSUS code, start with the product’s exact material identity and form. Review the relevant subheadings and legal notes to determine whether the item is a particular element or isotope, a compound, a mixture, or a residue, and whether a special distinction such as fissile or fertile status applies. The product’s composition, isotope information, concentration, and intended form may be needed; classification of unusual nuclear materials may require a customs broker or other qualified specialist.
What to check
- Confirm the exact chemical element, isotope, compound, mixture, or residue described by the product documentation.
- Check whether the material is identified as fissile or fertile and whether that distinction appears in the applicable subheading.
- Compare the product’s composition, concentration, physical form, and radioactive specifications with the wording of the candidate 8-digit provisions.
- Do not classify solely from a trade name, safety-sheet headline, or intended use; verify the technical description and supporting records.
- Ask a customs broker or seek a binding classification decision when the material’s identity, isotope status, or mixture composition is uncertain.
HTS heading 2844 summary
Radioactive chemical elements and radioactive isotopes 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.
Sub-categories
| Code | Description |
|---|---|
| 2844.10 | Natural uranium and its compounds; alloys, dispersions (including cermets), ceramic products and mixtures containing natural uranium or natural uranium compounds |
| 2844.30 | Uranium depleted in U235 and its compounds; thorium and its compounds; alloys, dispersions (including cermets), ceramic products and mixtures containing uranium depleted in U235, thorium, or compounds of these products |

Common questions
What products fall under HTS heading 2844?
Radioactive chemical elements and radioactive isotopes (including the fissile or fertile chemical elements and isotopes) and their compounds; mixtures and residues containing these products. 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.
