9902.09.78 - Mixtures containing (1S,2R,3S,4R,5S,6S)-2,3,4,5,6-Pentahydroxycyclohexyl 2-amino-4-{[carboxy(imino) methyl]amino}-2,3,4,6-tetradeoxy-α-D-arabino-hexopyranoside (CAS No. 19408-46-9) (Kasugamycin) and application adjuvants (provided for in subheading 3808.92.50)

This HTS classification, 9902.09.78, specifically covers mixtures containing Kasugamycin (CAS No. 19408-46-9), a complex chemical compound identified by its IUPAC name (1S,2R,3S,4R,5S,6S)-2,3,4,5,6-Pentahydroxycyclohexyl 2-amino-4-{[carboxy(imino) methyl]amino}-2,3,4,6-tetradeoxy-α-D-arabino-hexopyranoside, along with application adjuvants. These mixtures are intended for use in agricultural applications, particularly as fungicides or bactericides. The inclusion of "application adjuvants" signifies that these are formulated products designed for effective and targeted delivery in agricultural settings.

Distinguishing this category from its siblings within Chapter 99, which broadly covers temporary legislation and trade agreement provisions, is its specific focus on a particular agricultural chemical mixture under a special provision. While other Chapter 99 headings might address temporary import restrictions or modifications for various goods, 9902.09.78 is a precise designation for Kasugamycin-based formulations. Furthermore, it differs from headings in earlier chapters that classify unmixed active ingredients or broader categories of agricultural chemicals without this specific trade agreement or temporary legislation context.

As a leaf node, HTS 9902.09.78 does not have further subdivisions. Therefore, classification under this heading hinges on the confirmed presence of Kasugamycin and accompanying adjuvants, with the intent of agricultural application. Importers must ensure their product meets the exact chemical identity and formulation criteria outlined in the description to correctly utilize this specific provision, which likely reflects a temporary trade measure or tariff treatment for this particular agricultural product.
