Overview

This HTS classification, 9902.07.66, designates a specific chemical compound: N-(5,7-dimethoxy[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)-2-methoxy-4-(trifluoromethyl)-3-pyridine-sulfonamide, commonly known as Pyroxsulam. This entry falls under Chapter 99, which encompasses temporary legislation and modifications related to trade agreements and additional import restrictions. The specific inclusion of this compound under subheading 2935.90.75 indicates it is likely a temporary measure or subject to special import provisions due to its agricultural or trade-related implications, rather than its inherent chemical classification in the main HTS body.

Unlike the preceding sibling categories which focus on live animals (Chapters 01), this classification pertains to a synthetic organic chemical. Its purpose is highly specific, likely related to agricultural applications as indicated by its reference to import restrictions under Section 22 of the Agricultural Adjustment Act. Therefore, its classification is driven by temporary regulatory measures rather than its primary composition or use as a general chemical commodity.

As a leaf node within Chapter 99, HTS 9902.07.66 does not have further subcategories. Its precise classification is dictated by the specific temporary provisions and restrictions outlined for this particular chemical compound. Any importer or exporter dealing with Pyroxsulam must consult the full text of the relevant temporary legislation and any accompanying notes to ensure full compliance with the specified import requirements.
