HTS US: 2811.XX.XXXX
Description
This heading encompasses a broad range of other inorganic acids and inorganic oxygen compounds derived from nonmetal elements, which are not classified elsewhere. The products under this classification include various acids important in industrial, chemical, and manufacturing processes, as well as oxygen compounds used in different applications.
Included are both simple and complex inorganic acids such as hydrofluoric acid and arsenic acid, inorganic oxygen compounds like carbon dioxide and silicon dioxide, and other related substances.
