HTS 2844: Radioactive chemical elements and radioactive isotopes…
HTS heading 2844 covers radioactive chemical elements and radioactive isotopes (including the fissile or fertile chemical elements and isotopes) and their compounds; mixtures and residues containing these products. It has 12 tariff lines with a duty rate; the general (MFN) rates are Free (8 lines), 5% (3 lines), 5.5% (1 line).
Imports may also owe Chapter 99 tariffs (Section 232, 301 or 201) depending on origin and date, plus the Merchandise Processing Fee and, by sea, the Harbor Maintenance Fee.

Chapter 99 tariffs can be added on top: calculate the full amount.
Do Section 301, 232 or 201 tariffs apply to HTS 2844?
It depends on the 8- or 10-digit subheading, the country of origin, the entry date and, for Section 232, the metal content. These additional duties are listed in Chapter 99 of the HTS. The free duty calculator checks each program for a given code, origin and date and shows which apply and why.
What fees are added to an import under HTS 2844?
Formal entries pay the Merchandise Processing Fee of 0.3464% of value (minimum $34.58, maximum $670.86 in FY2027). Ocean shipments also pay the Harbor Maintenance Fee of 0.125% of value. See the import duty calculator for how they combine.
