9902.01.48 - Potassium fluotitanate (Dipotassium hexafluorotitanate(2-)) (CAS No. 16919-27-0) (provided for in subheading 2826.90.90)

This HTS category, 9902.01.48, specifically covers Potassium fluotitanate, also known as Dipotassium hexafluorotitanate(2-), identified by CAS Number 16919-27-0. This substance is classified under this temporary provision due to specific trade agreement legislation or additional import restrictions proclaimed under Section 22 of the Agricultural Adjustment Act. Its underlying classification is found within subheading 2826.90.90, indicating it is a titanium compound that does not fit into more specific categories within Chapter 28.

As this is a leaf node within Chapter 99, it does not have further subdivisions. Its inclusion in this chapter signifies a special, likely temporary, tariff treatment or restriction that overrides its standard classification under Chapter 28. Unlike the broader categories found at the root of the HTS (e.g., live animals in Chapter 01), this entry pertains to a very specific chemical compound with unique import regulations.

The practical classification criteria for this entry revolve around the precise chemical identity of Potassium fluotitanate and the specific regulatory status designated by its presence in Chapter 99. Importers and customs brokers must be aware of the associated temporary legislation or proclaimed restrictions when importing this compound to ensure compliance with all applicable trade policies.
