9902.10.11 - Mixtures containing methyl 4-{[(3-methoxy-4-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl) carbonyl] sulfamoyl}-5-methyl-3-thiophenecarboxylate (Thiencarbazone-methyl) (CAS No. 317815-83-1); 2-{[(4,6-Dimethoxy-2-pyrimidinyl) carbamoyl] sulfamoyl}-4-formamido-N,N-dimethylbenzamide (Foramsulfuron) (CAS No. 173159-57-4); and methyl 3-chloro-5-{[(4,6-dimethoxy-2-pyrimidinyl) carbamoyl] sulfamoyl}-1-methyl -1H-pyrazole-4-carboxylate (Halosulfuron-methyl) (CAS No. 100784-20-1) and application adjuvants (provided for in subheading 3808.93.15).

This HTS code, 9902.10.11, specifically classifies certain agricultural chemical mixtures intended for use as pesticides. It covers formulations containing three active ingredients: Thiencarbazone-methyl, Foramsulfuron, and Halosulfuron-methyl. These are herbicides, often used in conjunction with application adjuvants, which are themselves classified under subheading 3808.93.15. The inclusion of "application adjuvants" is a key characteristic of this specific subheading.

Given that this node is within Chapter 99, which pertains to temporary legislation and special provisions, its primary distinction from broader agricultural chemical categories found elsewhere in the HTS (e.g., Chapter 38) lies in its temporary or specific trade agreement-related nature. While other sections might classify the active ingredients or their components individually, this code addresses pre-formulated mixtures with specific import conditions or restrictions imposed under special tariff provisions.

As a leaf node, 9902.10.11 does not have further subcategories. This means that any mixture falling under this description, containing these specific active ingredients and associated adjuvants under the described temporary legislation, will be classified directly here. The classification hinges on the presence of all enumerated active ingredients and the context of their import under special tariff provisions.
