9902.06.75 - 1-(4-Chlorophenoxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)-2-butanone (Triadimefon) (CAS No. 43121-43-3) (provided for in subheading 2933.99.22).

This HTS category, 9902.06.75, pertains to a specific temporary import provision for the fungicide Triadimefon, chemically identified as 1-(4-Chlorophenoxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)-2-butanone. Its inclusion within Chapter 99 signifies a temporary modification or restriction related to its importation, often linked to agricultural or trade policy adjustments under Section 22 of the Agricultural Adjustment Act.

Unlike the primary chapters of the HTS (Chapters 1-97) which classify goods based on their inherent characteristics, composition, and intended use, Chapter 99 operates as a supplemental section. It addresses items that may have a standard classification elsewhere but are subject to specific, temporary tariff treatments or quantitative restrictions. Therefore, while Triadimefon would typically be classified under its chemical designation in a chapter like 29 (Organic Chemicals), this 9902 code indicates a special, time-limited import rule.

As this is a leaf node, there are no further subcategories within 9902.06.75. Its classification is definitive for the specified product under the current temporary legislation. Classification professionals should refer to the accompanying notes and proclamations associated with Chapter 99 to understand the exact nature of the restriction or provision, such as duty rates, quotas, or specific documentation requirements, beyond its primary classification under subheading 2933.99.22.
