2833.11.50.50 - Other

This HTS subheading, 2833.11.50.50, encompasses disodium sulfate that does not fit into the more specific category of anhydrous disodium sulfate. It serves as a residual classification for disodium sulfate where the presence of water of crystallization is a defining characteristic, distinguishing it from its completely dehydrated counterpart.

The primary distinction between this category and its sibling, 2833.11.50.10 (Anhydrous), lies in the hydration state. While anhydrous disodium sulfate is completely free of water, the "Other" category implicitly includes forms of disodium sulfate that contain water of crystallization, such as the decahydrate (Glauber's salt). Classification hinges on whether the product is presented in its dehydrated form or as a hydrated salt.

As this is a leaf node within the HTS structure, there are no further subcategories to explore. Therefore, the practical classification criteria for this subheading revolve around the direct identification of disodium sulfate that is not anhydrous, often through analysis of its physical properties or accompanying documentation indicating its hydrated form.
