2833.11.50 - Other

This HTS category, 2833.11.50, "Other," encompasses disodium sulfate that does not fall under the specific description of "salt cake." Salt cake, classified under 2833.11.10, typically refers to crude sodium sulfate generated as a byproduct of certain industrial processes. This category therefore covers disodium sulfate in forms or purities that are distinct from this industrial byproduct.

Disodium sulfate, chemically known as sodium sulfate, is an inorganic salt. Its utility spans various industrial applications, including the manufacture of detergents, glass, paper, and textiles. While the sibling category 2833.11.10 is reserved for the less refined form, this category is intended for disodium sulfate intended for more specialized or purified uses.

To further refine classification within this category, two subcategories exist. 2833.11.50.10 specifically designates anhydrous forms of disodium sulfate, meaning it contains no water molecules. The remaining disodium sulfate, which possesses some degree of hydration, is classified under 2833.11.50.50, "Other." This distinction is critical for accurate duty assessment and trade reporting.
