9902.04.99 - S-4-Chlorobenzyl diethylcarbamothioate (Thiobencarb) (CAS No. 28249-77-6) (provided in subheading 2930.20.10)

This HTS category, 9902.04.99, specifically covers S-4-Chlorobenzyl diethylcarbamothioate, more commonly known as Thiobencarb. This chemical compound, identified by CAS Number 28249-77-6, is recognized under the broader subheading 2930.20.10 as a carbamate derivative. Its inclusion within Chapter 99 signifies its presence under temporary legislation and special provisions, often related to trade agreements or specific import restrictions enacted under agricultural adjustment acts.

Unlike the majority of sibling categories within the HTS, which represent broad classes of goods such as live animals or manufactured products, this node delves into a highly specific chemical substance. While other chapters might classify chemical compounds based on their general type (e.g., organic chemicals), 9902.04.99 isolates Thiobencarb due to unique regulatory considerations. Its classification is driven by its precise chemical identity and its potential application, which necessitates special tariff treatment.

As this is a leaf node, there are no further subcategories within 9902.04.99. The classification is definitive for Thiobencarb itself. Any variations or related compounds would likely fall under different HTS codes, potentially within Chapter 29 or other specialized sections if subject to distinct trade measures. The critical classification criterion here is the exact chemical name and its CAS number, ensuring that only this specific compound receives the designated tariff treatment.
