9902.01.33 - Thionyl chloride (CAS No. 7719-09-7) (provided for in subheading 2812.17.00)

This HTS category, 9902.01.33, specifically covers Thionyl chloride (CAS No. 7719-09-7). It is important to note that while Thionyl chloride is the subject of this classification, its primary classification is found under subheading 2812.17.00. This temporary provision indicates a specific regulatory or trade agreement-related treatment applied to Thionyl chloride, separate from its standard chemical classification.

As a temporary legislation or special classification provision within Chapter 99, this category differs significantly from the typical product-based categories found elsewhere in the HTS, such as live animals (e.g., 0101, 0102). These sibling categories are based on fundamental biological categories of animals. In contrast, 9902.01.33 pertains to a specific chemical compound and its unique trade treatment under special provisions, rather than a broad product group.

Since this is a leaf node, there are no further subcategories to explore. The classification is definitive for Thionyl chloride under these specific temporary provisions. Classification under this heading is determined by the identity of the chemical substance, Thionyl chloride, and the application of the specific temporary measures or legislation associated with this 9900 series code.
