Overview
This HTS category, 9902.01.67, specifically covers Disodium dioxido(dioxo)tungsten, also known as disodium wolframate, identified by CAS number 13472-45-2. This compound is a tungsten salt and falls under the broader umbrella of temporary legislation and special classification provisions. Its inclusion here signifies a specific treatment or restriction that deviates from its standard classification under Chapter 28, which covers inorganic chemicals.
Unlike the numerous sibling categories at the HTS Database Root level that pertain to live animals, this category focuses on a specific chemical compound. The primary distinction lies in its nature as a manufactured chemical substance rather than a biological organism. Furthermore, its placement within Chapter 99 indicates that it is subject to unique import regulations or tariff treatments established for specific policy or trade agreement purposes, rather than general commodity classifications.
As this is a leaf node within the HTS structure, there are no further subcategories. Classification within 9902.01.67 is definitive for disodium wolframate. For customs purposes, it is crucial to note that while the chemical itself is provided for in subheading 2841.80.00, its entry under 9902.01.67 signifies that additional, specific provisions govern its importation. Importers should verify the exact requirements and any associated documentation mandated by this temporary classification.
