Overview

Heading 2833 encompasses a wide range of inorganic sulfate compounds. This category specifically includes simple sulfates of various metals, alums (double sulfates of aluminum with another metal), and peroxosulfates (also known as persulfates). These substances are generally characterized by the presence of the sulfate ion (SO₄²⁻) and are crucial raw materials or intermediates in numerous industrial processes, including water treatment, detergents, textiles, and pigments.

When classifying within this heading, it is essential to differentiate from other inorganic chemical categories. For instance, while heading 2833 deals with sulfates, other headings within Chapter 28 cover different classes of inorganic compounds such as oxides, hydroxides, and chlorides of metals, or other sulfur compounds like sulfites or thiosulfates, which have distinct chemical structures and properties. The presence of the sulfate radical is the defining characteristic for classification under 2833.

Within heading 2833, further subdivisions exist to distinguish between specific types of sulfates. The subcategories differentiate based on the cation associated with the sulfate ion, such as sodium sulfates, other metallic sulfates, and the specialized groups of alums and peroxosulfates. This granular breakdown allows for more precise classification based on the specific chemical composition and potential applications of the sulfate compound being imported or exported.
