Overview

This HTS classification, 9902.09.51, specifically covers certain product mixtures designated for agricultural use. The featured products are complex chemical formulations containing the active ingredients Trifloxystrobin and Prothioconazole, identified by their respective CAS numbers. These mixtures are intended for use as pesticides or fungicides, as indicated by their parenthetical reference to subheading 3808.92.15, which generally covers preparations for the retail sale of insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products.

Distinguishing this category from its siblings is crucial for accurate classification. While many sibling categories at the root level deal with live animals, this node falls under Chapter 99, which pertains to temporary legislation, trade agreements, and special import restrictions. Therefore, its primary distinction lies in its status as a temporary or specially regulated item, rather than a broad category of goods based on inherent physical characteristics like live animals. The specific chemical composition and intended agricultural application are key identifiers for goods classified under 9902.09.51.

As a leaf node within the HTS, this category does not have subcategories. Its specificity means that any product meeting the detailed description of containing both Trifloxystrobin and Prothioconazole, and falling under the provisions of Chapter 99, will be classified directly here. Classification hinges on confirming the presence of these specific active ingredients and adherence to the temporary legislative or trade agreement provisions associated with Chapter 99, as opposed to general classification within Chapter 38.
