2833.11.50.10 - Anhydrous

This classification, 2833.11.50.10, specifically covers anhydrous disodium sulfate that is not otherwise classified. Disodium sulfate is a salt of sulfuric acid with the chemical formula Na₂SO₄. The "anhydrous" designation is critical, indicating the absence of water molecules within its crystalline structure, distinguishing it from hydrated forms. This category is relevant for importers and exporters dealing with this specific chemical compound for various industrial applications.

The distinction from its sibling category, 2833.11.50.50 (Other), lies in the precise chemical form and absence of hydration. While both fall under disodium sulfate, this subcategory is for the pure, water-free version, whereas the "Other" category would encompass any disodium sulfate not meeting the anhydrous criterion, potentially including various hydrated forms or those with minor impurities not specified elsewhere.

As this is a leaf node in the HTS classification, there are no further subcategories under 2833.11.50.10. Classification decisions at this level will rely on confirming the material is indeed disodium sulfate and that it is in its anhydrous state, based on product specifications, laboratory analysis, or manufacturer declarations. This ensures accurate tariff application and compliance with import/export regulations for this chemical commodity.
