## How it is structured

2844.42 is a six-digit subheading. Its first two digits, 28, are the chapter; the first four, 2844, are heading 28.44; the last two, 42, identify the subheading within the heading.

Countries add their own digits after these six for their national tariff lines.

- Chapter 28: Inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes
- Heading 28.44: Radioactive chemical elements and radioactive isotopes (including the fissile or fertile chemical elements and isotopes) and their compounds; mixtures and residues containing these products
- Within the heading: Radioactive elements and isotopes and compounds other than those of subheading 2844 10, 2844 20 or 2844 30; alloys, dispersions (including cermets), ceramic products and mixtures containing these elements, isotopes or compounds; radioactive residues
- Subheading 2844.42: Actinium-225, actinium-227, californium-253, curium-240, curium-241, curium-242, curium-243, curium-244, einsteinium-253, einsteinium-254, gadolinium-148, polonium-208, polonium-209, polonium-210, radium-223, uranium-230 or uranium-232, and their compounds; alloys, dispersions (including cermets), ceramic products and mixtures containing these elements or compounds

## In other countries

No national tariff lines under 2844.42 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 2844.42 at six digits and add their own digits after it.
