9902.10.03 - Mixtures of N-[[(4,6-dimethoxy-2-pyrimidinyl) amino] carbonyl]-3-(ethylsulfonyl)-2-pyridinesulfonamide (Rimsulfuron) (CAS No. 122931-48-0) and application adjuvants (provided for in subheading 3808.93.15)

This HTS category, 9902.10.03, specifically covers mixtures containing the active ingredient Rimsulfuron (N-[[(4,6-dimethoxy-2-pyrimidinyl) amino] carbonyl]-3-(ethylsulfonyl)-2-pyridinesulfonamide) alongside application adjuvants. These mixtures are primarily intended for use as herbicides or plant growth regulators, offering a specialized solution for agricultural or horticultural applications. The inclusion of CAS No. 122931-48-0 serves as a precise identifier for the Rimsulfuron component.

Distinguishing this category from its siblings within Chapter 99 reveals its unique purpose. While other Chapter 99 headings may address temporary trade measures or specific import restrictions, 9902.10.03 is designated for a particular type of chemical mixture with agricultural utility. Unlike broader categories that might cover generic chemicals or other classes of agricultural inputs, this heading is narrowly defined by the presence of Rimsulfuron and its associated adjuvants, signaling specific regulatory or tariff treatment. It is important to note that the application adjuvants themselves are referenced as being provided for in subheading 3808.93.15, reinforcing the compound nature of the classification.

As a leaf node, HTS code 9902.10.03 does not have further subcategories. Therefore, classification at this level is definitive for qualifying mixtures. Importers and exporters should ensure that the product precisely matches the chemical composition and intended use described, as any deviation may necessitate classification under a different HTS heading. The detailed chemical name and CAS number are crucial for verifying compliance and ensuring accurate customs declarations.
