2842.90.90.50 - Other

This HTS classification, 2842.90.90.50, encompasses "Other" salts of inorganic acids or peroxoacids (including aluminosilicates whether or not chemically defined), which do not fall under more specific subheadings within 2842.90.90. It covers a broad range of inorganic chemical compounds that are salts derived from inorganic acids or peroxoacids, as well as aluminosilicate compounds that may or may not have a defined chemical structure.

This category is distinguished from its sibling, 2842.90.90.10 (Selenides and tellurides), by the specific chemical composition of the salts. While selenides and tellurides are also considered inorganic compounds, this subheading is reserved for salts formed with acids other than those that directly involve selenium or tellurium as the acidic component. The exclusion of specific salt types is crucial for accurate classification.

As a leaf node in the HTS structure, this category does not have further subdivisions. Therefore, classification into this subheading relies on a thorough analysis of the chemical nature of the product to confirm it is a salt of an inorganic acid or peroxoacid, or an aluminosilicate, and that it is not specifically classified elsewhere within Chapter 28, particularly under its sibling category. Examples might include certain borates, phosphates, sulfates, or silicates that do not have a more precise tariff classification.
