9902.09.22 - Product mixtures containing 1-(6-chloro-3-pyridinyl)methyl-N-nitroimidazolidin-2-ylideneamine (Imidacloprid) (CAS No. 138261-41-3) and 3, 7, 9, 13-tetramethyl-5, 11-dioxa-2, 8, 14-trithia-4, 7, 9, 12-tetraazapentadeca-3, 12-diene-6, 10-dione (Thiodicarb) (CAS No. 59669-26-0) (provided for in subheading 3808.91.25)

This HTS category, 9902.09.22, specifically covers product mixtures that contain both Imidacloprid and Thiodicarb. Imidacloprid (CAS No. 138261-41-3) is a systemic insecticide belonging to the neonicotinoid class, while Thiodicarb (CAS No. 59669-26-0) is a carbamate insecticide. The presence of these two active ingredients in combination defines the scope of this particular classification.

This heading is situated within Chapter 99, which pertains to temporary legislation, modifications to trade agreements, and import restrictions enacted under specific U.S. legislation. Unlike the broad commodity classifications found in earlier chapters of the HTS (such as Chapter 38 for prepared chemical products), this category is a provision for special circumstances and temporary measures. Its purpose is to manage the importation of specific, regulated mixtures of pesticides, likely due to trade policy, environmental concerns, or other temporary legislative directives.

As a leaf node, this classification has no further subcategories. Therefore, importers should focus on the precise composition of the product. Any mixture containing both Imidacloprid and Thiodicarb, and that falls under the scope of the temporary legislation or modifications indicated by the Section XXII and Chapter 99 headings, will be classified here. It is crucial to verify that the product is indeed a *mixture* of these two specific active ingredients and not a product containing only one, or other chemical compounds not listed in the description.
