2841.70.10.00 - Of ammonium

This HTS category, 2841.70.10.00, specifically covers molybdates that are derivatives of ammonium. Molybdates are salts or esters of molybdic acid, which is an oxyacid of molybdenum. The defining characteristic of this classification is the presence of ammonium as the cation in the chemical compound. These substances can be in various forms, such as crystalline solids or aqueous solutions, and are utilized in a range of industrial applications, including as catalysts, pigments, corrosion inhibitors, and in laboratory reagents.

The primary distinction between this subcategory and its sibling, 2841.70.50.00 (Other molybdates), lies in the specific cation. While this entry is exclusively for ammonium molybdates, the "Other" category encompasses all molybdates that do not contain ammonium as their cation. Therefore, any molybdate where the accompanying ion is sodium, potassium, calcium, or any other element or radical besides ammonium would fall under the sibling category.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification under 2841.70.10.00 is final for ammonium molybdates. When classifying, customs professionals should confirm the chemical composition to ensure the presence of ammonium is definitively established, differentiating it from other metallic or non-metallic molybdates.
