2801.30.10.00 - Fluorine

This HTS classification covers elemental fluorine, a highly reactive, pale yellow gas. It is defined as the pure element in its gaseous state. This category is distinct from its sibling, bromine, which is also an elemental halogen but is a reddish-brown liquid at room temperature and possesses different chemical and physical properties, leading to its separate classification.

Elemental fluorine is the most electronegative and reactive of all elements. Its primary applications are in specialized industrial processes, such as the production of uranium hexafluoride for nuclear fuel, and in the manufacture of fluorocarbons and high-performance polymers. Classification under this code is based on the substance being pure fluorine, not a compound containing fluorine, which would be classified elsewhere in Chapter 28 or subsequent chapters depending on the compound.
