9902.01.41 - Ammonium bifluoride (Ammonium fluoride hydrofluoride (1:1:1)) (CAS No. 1341-49-7) (provided for in subheading 2826.19.10)

This HTS category, 9902.01.41, specifically covers Ammonium bifluoride, also known by its chemical synonyms Ammonium fluoride hydrofluoride (1:1:1), with the CAS number 1341-49-7. This classification falls under Chapter 99, which pertains to temporary legislation and special trade provisions, including restrictions proclaimed under Section 22 of the Agricultural Adjustment Act. While the goods themselves are chemical compounds, their inclusion in Chapter 99 signifies they are subject to specific, potentially temporary, import restrictions or reporting requirements beyond standard tariff classifications.

Given that this is a leaf node within the HTS classification system, there are no further subcategories to detail. The primary function of this classification is to identify and track the import of ammonium bifluoride when subject to the specific provisions outlined in Chapter 99. It is important to note that the underlying chemical classification for ammonium bifluoride, without these temporary provisions, would typically be found in Chapter 28. This entry serves as an overlay to ensure compliance with additional legislative measures.
