9902.09.27 - Mixtures of 3,6-bis(2-chlorophenyl)-1,2,4,5-tetrazine (Clofentezine) (CAS No.74115-24-5) and application adjuvants (provided for in subheading 3808.91.25)

This HTS category, 9902.09.27, specifically covers mixtures containing Clofentezine (3,6-bis(2-chlorophenyl)-1,2,4,5-tetrazine), identified by CAS No. 74115-24-5, when these mixtures are combined with application adjuvants. These adjuvants are typically those already classified under subheading 3808.91.25, which relates to preparations for agricultural, horticultural, or domestic use, often functioning as insecticides, fungicides, or herbicides. The defining characteristic of this classification is the presence of Clofentezine in combination with specific types of application enhancers.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike the broad categories of live animals (0101-0105) or other general merchandise found elsewhere in the HTS, 9902.09.27 pertains to highly specific chemical mixtures used in pest control. Its placement within Chapter 99 signifies that it falls under temporary legislation or special provisions, often related to import restrictions or trade agreement modifications, setting it apart from standard tariff classifications for general chemicals or finished products.

As this is a leaf node, there are no further subcategories within 9902.09.27. Therefore, classification into this heading is final, contingent upon the imported goods meeting the precise description of containing Clofentezine and application adjuvants of the type specified in subheading 3808.91.25. Importers should ensure that documentation clearly identifies both components of the mixture to avoid misclassification.
