9902.07.57 - 2-(2-Chloroethoxy)-N-[(4-methoxy-6-methyl-1,3,5-triazin-2- yl)carbamoyl]benzenesulfonamide (Triasulfuron) (CAS No. 82097-50-5) (provided for in subheading 2935.90.75)

This HTS code, 9902.07.57, specifically classifies the herbicide known as Triasulfuron (CAS No. 82097-50-5), which is chemically identified as 2-(2-Chloroethoxy)-N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)carbamoyl]benzenesulfonamide. This classification is established under Chapter 99, which pertains to temporary legislation and modifications to the Harmonized Tariff Schedule, often enacted due to trade agreements or specific import restrictions like those proclaimed under Section 22 of the Agricultural Adjustment Act. The inclusion of this chemical under Chapter 99 signifies that its tariff treatment or import regulations may be subject to change or specific controls beyond its primary classification.

While the broader HTS system encompasses a vast array of goods, from live animals (Chapters 01) to manufactured products, this particular entry falls within a specialized chapter for temporary measures. It is distinct from entries in Chapters 1 through 98, which provide the permanent tariff classifications for goods based on their inherent characteristics and intended use. The reference to subheading 2935.90.75 indicates that, absent the temporary provisions of Chapter 99, Triasulfuron would ordinarily be classified as a sulfonamide derivative. However, the specific HTS code 9902.07.57 imposes additional, potentially more restrictive, conditions on its importation.

As this node is a leaf node, it does not have subcategories. Therefore, classification under 9902.07.57 is final and conclusive for the described substance. Importers must be aware that the conditions and duties associated with this specific HTS code may be temporary and subject to revision, necessitating careful monitoring of regulatory updates affecting this chemical.
