2833.19.00.00 - Other

This HTS category, 2833.19.00.00, encompasses "Other" sodium sulfates that are not specifically classified elsewhere within the sulfates group. This typically includes various forms of sodium sulfate that do not fit the precise definition of disodium sulfate (2833.11), such as sodium sesquisulfate or other hydrated or anhydrous forms not otherwise specified. The classification hinges on the chemical composition being primarily sodium sulfate, excluding compounds where sodium sulfate is a secondary component or part of a more complex chemical structure.

Unlike its sibling category, 2833.11 (Disodium sulfate), this "Other" category serves as a residual classification for sodium sulfate compounds. Disodium sulfate, also known as anhydrous sodium sulfate or salt cake, is a specific chemical entity. This category captures other sodium sulfate variants, potentially including those with different stoichiometric ratios of sodium to sulfate ions or those that are less commonly traded and thus not afforded a more specific subheading.

As this is a leaf node in the HTS classification, there are no further subcategories. The primary consideration for classifying goods under 2833.19.00.00 is to confirm that the product is indeed a sodium sulfate and does not meet the criteria for disodium sulfate or any other specifically listed sulfate or alum. Practical classification will therefore rely on detailed chemical analysis and product specifications to ensure it is not more accurately placed in a distinct subheading.
