9902.10.13 - (RS)-5-Amino-1-[2,6-dichloro-4-(trifluoromethyl) phenyl]-4-(trifluoromethysulfinyl)-1H-pyrazole-3-carbonitrile (Fipronil) (CAS No. 120068-37-3) (provided for in subheading 3808.93.50)

This HTS category, 9902.10.13, specifically covers the chemical compound (RS)-5-Amino-1-[2,6-dichloro-4-(trifluoromethyl) phenyl]-4-(trifluoromethysulfinyl)-1H-pyrazole-3-carbonitrile, commonly known as Fipronil. This entry is situated within Chapter 99, which pertains to temporary legislation and modifications related to trade agreements and agricultural import restrictions. Its inclusion here indicates a specific tariff treatment or restriction imposed on this particular chemical, overriding or supplementing its classification under its primary product chapter.

Unlike sibling categories found at the HTS Database Root level, which generally deal with broad classes of goods such as live animals (e.g., 0101, 0102), this node is highly specific. It does not represent a general commodity but a precisely identified chemical substance. The distinction lies in its classification as a specialized chemical with particular regulatory oversight, as indicated by its placement in Chapter 99 and its explicit reference to a principal tariff line (3808.93.50), which likely pertains to insecticides.

As a leaf node, HTS Code 9902.10.13 has no further subcategories. Therefore, the focus for classification purposes is solely on the precise identification of the chemical Fipronil and adherence to any specific conditions or limitations associated with its temporary tariff or import restriction status under Chapter 99. Importers and customs brokers must verify the current validity and applicable requirements for this code, as entries in Chapter 99 are subject to change based on prevailing trade policies and legislation.
