2813.90.50.00 - Other

This HTS category, 2813.90.50.00, specifically covers "Other" sulfides of nonmetals and commercial phosphorus trisulfide, that do not fall under the more specific classifications of arsenic or phosphorus sulfides. Essentially, it acts as a residual category for such chemical compounds when they are not explicitly categorized elsewhere within heading 2813.

It is crucial to differentiate this category from its siblings. HTS code 2813.90.10.00 is exclusively for sulfides of arsenic, while 2813.90.20.00 pertains to sulfides of phosphorus. Therefore, classification under 2813.90.50.00 is appropriate only when the sulfide in question is of a nonmetal other than arsenic or phosphorus, or when it is a commercial form of phosphorus trisulfide that has not been further specified.

As this is a leaf node within the HTS structure, there are no further subcategories to explore. Classification decisions at this level should rely on a thorough examination of the chemical composition and intended use of the product, ensuring it does not meet the criteria for the more specifically defined sibling categories.
