9902.07.21 - (E)-{2-[6-(2-Chlorophenoxy)-5-fluoropyrimidin-4-yloxy] phenyl}(5,6-dihydro-1,4,2-dioxazin-3-yl)-N- methoxymethanimine (Fluoxastrobin) (CAS No. 361377-29-9) (provided for in subheading 2934.99.12)

This HTS category, 9902.07.21, specifically covers the chemical compound known as Fluoxastrobin (CAS No. 361377-29-9), identified by its systematic name (E)-{2-[6-(2-Chlorophenoxy)-5-fluoropyrimidin-4-yloxy] phenyl}(5,6-dihydro-1,4,2-dioxazin-3-yl)-N-methoxymethanimine. This designation falls under Chapter 99, which pertains to temporary legislation, modifications pursuant to trade agreements, and additional import restrictions proclaimed under Section 22 of the Agricultural Adjustment Act. While the primary chemical classification of Fluoxastrobin would typically reside within Chapter 29, its inclusion in Chapter 99 signifies specific import conditions or restrictions that supersede its standard tariff treatment.

Distinguishing this category from its siblings within Chapter 99 requires an understanding of the specific temporary provisions being applied. While sibling categories at this level might represent other chemical compounds or goods subject to similar temporary measures, 9902.07.21 is uniquely tied to Fluoxastrobin. The "provided for in subheading 2934.99.12" note within the description is crucial for understanding its origin, indicating that its standard classification would be as a heterocyclic compound. However, the Chapter 99 code dictates that it is subject to separate, temporary trade regulations.

As a leaf node in the HTS classification structure, this category does not have further subcategories. Classification under 9902.07.21 will be based on the precise identification of the imported merchandise as Fluoxastrobin, as well as adherence to any specific documentation or declaration requirements mandated by the temporary provisions outlined in Chapter 99. Importers must be aware of and comply with these additional requirements beyond the standard classification principles.
