9902.05.17 - S,S-Di-sec-butyl O-ethyl phosphorodithioate (Cadusafos) (CAS No. 95465-99-9) (provided for in subheading 2930.90.43)

This HTS category, 9902.05.17, specifically covers the insecticide and nematicide known as S,S-Di-sec-butyl O-ethyl phosphorodithioate, also identified by its CAS number 95465-99-9 and commonly referred to as Cadusafos. This provision falls under Chapter 99, which is reserved for temporary legislation, modifications to trade agreements, and specific import restrictions. The inclusion of Cadusafos within this chapter signifies a particular regulatory treatment, distinct from its placement in the permanent tariff schedule, likely due to specific trade policies or agricultural protection measures.

Given that this is a leaf node, there are no subcategories to introduce. The classification's purpose is to isolate and manage the import of Cadusafos, which is provided for under subheading 2930.90.43 in the permanent HTS. This means that while its chemical classification places it within organophosphorus compounds, its presence under 9902.05.17 indicates a temporary or specialized import control mechanism. The distinction from sibling categories, which are primarily live animals, is straightforward, as this category pertains to a specific agricultural chemical rather than livestock. The focus for classification professionals is on the accurate identification of Cadusafos and adherence to any associated temporary import requirements.
