9902.09.42 - Product mixtures containing 1-(4-chlorophenoxy)-3,3-dimethyl-1-[1,2,4] triazol-1-yl-butan-2-one (Triadimefon) (CAS No. 43121-43-3) and methyl (E)-methoxyimino-{(E)-2-[1-(α,α,α-trifluoro-m-tolyl) ethylideneaminooxy]-o-tolyl} acetate (Trifloxystrobin) (CAS No. 141517-21-7) (provided for in subheading 3808.92.15)

This HTS classification, 9902.09.42, covers specific product mixtures designated for temporary legislation, trade agreement modifications, or agricultural import restrictions. The core of this classification is a combination of two active pesticidal ingredients: Triadimefon (CAS No. 43121-43-3), a triazole fungicide, and Trifloxystrobin (CAS No. 141517-21-7), a strobilurin fungicide. These are not classified as individual chemicals but as a pre-formulated mixture.

This particular code is distinct from the primary commodity chapters of the HTS. While other HTS codes might classify Triadimefon or Trifloxystrobin individually (as typically found in Chapter 38, under subheading 3808.92.15 as indicated in the description), this code 9902.09.42 signifies a special provision. It is used for goods that are subject to temporary rules, quotas, or other trade-related measures that fall outside the standard tariff structure. Therefore, its focus is on the *regulatory status* of the product mixture rather than its fundamental chemical composition or intended use as a standalone commodity.

As this is a leaf node within Chapter 99, there are no further subcategories. Classification under 9902.09.42 is definitive for shipments meeting the specific product mixture criteria and falling under the proclaimed temporary legislative or trade agreement provisions. Importers must ensure compliance with the associated temporary restrictions or reporting requirements that dictate the use of this specific HTS code.
