9902.09.24 - Product mixtures containing (5s, 8s)-3-(2,5-dimethylphenyl)-8-methoxy-2-oxo-1-azaspiro [4.5] dec-3-en-4-yl ethyl carbonate (Spirotetramat) (CAS No. 203313-25-1) (provided for in subheading 3808.91.25)

This HTS category, 9902.09.24, pertains to specific product mixtures containing the active ingredient (5s, 8s)-3-(2,5-dimethylphenyl)-8-methoxy-2-oxo-1-azaspiro [4.5] dec-3-en-4-yl ethyl carbonate, also known as Spirotetramat. These mixtures are classified under this temporary provision because they are provided for in subheading 3808.91.25 of the Harmonized Tariff Schedule, indicating their primary function as insecticides. This specific classification is established under Chapter 99, which addresses temporary legislation and modifications to import restrictions.

The purpose of this specialized classification is to manage the import of these particular Spirotetramat-containing product mixtures, likely due to specific trade agreements, temporary legislative actions, or Section 22 of the Agricultural Adjustment Act. It distinguishes these chemical mixtures from other potential classifications by their precise chemical composition and their designated use as an insecticide, as indicated by their parenthetical reference to subheading 3808.91.25.

As a leaf node within the HTS structure, 9902.09.24 does not have subcategories. Its classification is highly specific, focusing on the precise chemical compound and its formulation as an insecticide. Therefore, for classification purposes, the defining criteria are the presence of Spirotetramat (CAS No. 203313-25-1) in a product mixture intended for pesticidal use, and its designated status under Chapter 99 provisions.
