Overview
This HTS category, 2833.29.20.00, specifically classifies sulfates of iron. These are inorganic chemical compounds where iron is combined with the sulfate radical (SO4). Examples include ferrous sulfate (iron(II) sulfate) and ferric sulfate (iron(III) sulfate), which are used in a variety of industrial applications such as water treatment, pigment production, and as a dietary supplement.
This classification distinguishes iron sulfates from other metal sulfates at the same level. For instance, it is separate from sulfates of cobalt (2833.29.10.00), vanadium (2833.29.30.00), chromium (2833.29.40.00), and zinc (2833.29.45.00), each of which covers sulfates of those specific metallic elements. The key differentiator is the presence of iron as the metallic cation.
As this is a leaf node in the HTS structure, there are no further subcategories under 2833.29.20.00. Therefore, the classification is definitive for iron sulfates. Any product meeting the description of an iron sulfate would be classified here, provided it is not specifically covered by a more precise or higher-level heading within Chapter 28 that might take precedence based on other characteristics or purities.
