9902.09.33 - Mixtures containing dimethyl (2aR, 3S, 4S, 4aR, 5S, 7aS, 8S, 10R, 10aS, 10bR)-10-acetoxy-3,5-dihydroxy-4[(1aR, 2S, 3aS, 6aS, 7S, 7aS)-6a-hydroxy-7a-methyl-3a,6a,7,7a-tetrahydro-2,7-methanofuro [2,3-b] oxireno[e]oxepin-1a(2H)-yl]-4-methyl-8-{[(2E)-2-methylbut-2-enoyl] oxy} octahydro-1H-naphtho [1,8a-c:4,5-b'c'] difuran-5,10a (8H)-dicarboxylate (Azadirachtin) (CAS No. 11141-17-6) (provided for in subheading 3808.91.50)

This HTS category, 9902.09.33, specifically covers mixtures containing Azadirachtin, identified by CAS No. 11141-17-6. Azadirachtin is a complex organic compound derived from the neem tree, known for its insecticidal and pesticidal properties. This classification is intended for Azadirachtin in its formulated mixture state, as provided for in subheading 3808.91.50, indicating its use as a pest control product.

Given that Chapter 99 of the HTS relates to temporary legislation and special provisions, this entry functions as a specific, temporary modification or restriction for Azadirachtin mixtures. It is crucial to distinguish this category from broader chemical classifications. While subheading 3808.91.50 provides the underlying classification for such pest control mixtures, 9902.09.33 indicates a particular regulatory treatment or restriction that may be in effect at the time of import or export.

As this is a leaf node within the HTS, there are no further subcategories under 9902.09.33. Classification at this level is definitive for the described Azadirachtin mixtures. Importers and exporters must consult the specific provisions and restrictions associated with this temporary HTS code, as these can change based on trade agreements or legislative actions under Section 22 of the Agricultural Adjustment Act.
