Overview

This HTS category, 9902.09.23, specifically covers certain product mixtures containing the chemical compound Spiromesifen, identified by CAS No. 283594-90-1. Spiromesifen is a known insect repellent and acaricide, and this classification applies to formulations where it is a primary active ingredient, intended for agricultural or pest control purposes. The "provided for in subheading 3808.91.25" notation indicates its reference to a more general classification for insecticides, fungicides, herbicides, and similar products under Chapter 38.

Within the broader framework of Chapter 99, which deals with temporary legislation and trade agreement modifications, this specific subheading acts as a temporary or specialized provision. Unlike the primary, broad categories of live animals found in Chapter 01 (e.g., horses, bovine animals, swine, sheep, goats, poultry), this HTS code pertains to a highly specific chemical product rather than live organisms. Its placement signifies a particular trade or regulatory treatment under current legislation.

As a leaf node, HTS 9902.09.23 does not have further subdivisions. Therefore, its function is to precisely identify and manage the import or export of Spiromesifen-based product mixtures under current trade regulations. Classification hinges on the confirmation of Spiromesifen as the active ingredient within the mixture, as well as adherence to any specific import restrictions or temporary measures associated with this subheading.
