9902.01.44 - Sodium hydrogen difluoride (CAS No. 1333-83-1) (provided for in subheading 2826.19.90)

This HTS classification covers Sodium hydrogen difluoride, identified by CAS No. 1333-83-1. This compound is a specific chemical substance with particular properties and applications. It is important to note that while it falls under Chapter 99, its primary classification is provided for in subheading 2826.19.90, indicating its underlying nature as a fluoride salt.

Chapter 99 is reserved for temporary legislation, trade agreement modifications, and specific import restrictions. Therefore, classification under HTS Code 9902.01.44 signifies that Sodium hydrogen difluoride is subject to these special provisions. This differs from the "sibling" categories which represent the vast majority of goods classified within the HTS, ranging from live animals and agricultural products to manufactured goods. This node is distinct because it addresses a specific chemical under a temporary or exceptional trade provision, rather than its general commodity classification.

As this node is a leaf node, there are no further subcategories. Classification under 9902.01.44 is final for this specific product under the described temporary legislation. Importers must consult the specific provisions associated with this code to understand any additional requirements, quotas, or duties that may apply beyond its base tariff classification.
