2833.22.00.00 - Of aluminum

This HTS category, 2833.22.00.00, specifically classifies aluminum sulfates. These are inorganic chemical compounds that are salts of sulfuric acid and aluminum. Aluminum sulfates are typically white crystalline solids and find widespread industrial applications, most notably as flocculants in water purification and in the paper manufacturing industry for sizing.

This category is distinguished from its siblings based on the specific metal cation present in the sulfate compound. For instance, 2833.21.00.00 covers sulfates of magnesium, while 2833.25.00.00 classifies copper sulfates. Therefore, the defining characteristic for this HTS code is the presence of aluminum as the primary metallic component of the sulfate salt.

As this node represents a leaf category within the HTS structure, there are no further subcategories to introduce. Classification within 2833.22.00.00 is determined solely by the presence of aluminum sulfate, distinguishing it from other metal sulfates at the same hierarchical level.
