Analysis
HTS 2844.44.00 covers radioactive residues under heading 2844 (radioactive chemical elements and radioactive isotopes (including the fissile or fertile…).
Rates on the nearby lines range from duty-free to 5.5%. The costliest confusion would be with 2844.30.10 (uranium depleted in U235 and its compounds; thorium and its…) at 5.5%, a difference of 5.5 points on the customs value.
There is no general-rate duty on this line, which puts it with roughly 29% of the 274 tariff lines in chapter 28 that are also free. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Census statistics map these goods to NAICS 325180 (Other Basic Inorganic Chemical Manufacturing), an industry of 705 US establishments employing 41,447 people, the industry a domestic producer of these goods reports under.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
