HTS US: 2957.XX.XXXX
Description
HTS Code 2957 includes a group of inorganic chemical compounds mainly consisting of chlorates, perchlorates and peroxides. These substances are widely used in various industrial processes, including chemical manufacturing, disinfection, and as oxidizing agents in different applications.
- Chlorates: Compounds containing the chlorate ion (ClO3−), often used in herbicides, explosives, and bleaching agents.
- Perchlorates: Salts that contain the perchlorate ion (ClO4−), commonly applied in rocket propellants, pyrotechnics, and certain types of analytical chemistry.
- Peroxides: Compounds with the peroxide ion (O22−), frequently utilized as bleaching agents, disinfectants, and initiators in polymerization reactions.
These compounds are presented primarily in solid forms such as powders, granules, or crystals.
