9902.05.84 - (5-chloro-2-methoxy-4-methyl-3-pyridyl)(4,5,6-trimethoxy-o- tolyl)methanone (Pyriofenone) (CAS No. 688046-61-9) (provided for in subheading 2933.39.21) and any formulations containing such compound (provided for in subheading 3808.92.15)

This HTS category, 9902.05.84, specifically addresses the chemical compound (5-chloro-2-methoxy-4-methyl-3-pyridyl)(4,5,6-trimethoxy-o-tolyl)methanone, also known as Pyriofenone (CAS No. 688046-61-9). It also encompasses any formulations that contain this specific compound. The inclusion within Chapter 99 indicates that these are subject to special classification provisions, temporary legislation, or temporary modifications under trade agreements or Section 22 of the Agricultural Adjustment Act.

Distinguishing this category from its siblings at the HTS Database Root level is straightforward, as those siblings primarily concern live animals, whereas 9902.05.84 pertains to a specific chemical substance and its formulations. The primary classification criteria here are the precise chemical identity of Pyriofenone and its presence within a given product, irrespective of its ultimate use, which may be further specified by its provision under subheadings 2933.39.21 for the pure compound or 3808.92.15 for its formulations.

As this node is a leaf node within the HTS structure, there are no further subcategories. Classification within 9902.05.84 depends entirely on whether the imported merchandise is the specified chemical compound or a formulation containing it. This specialized entry serves to track and potentially regulate trade in this particular chemical and its associated products under specific trade or agricultural policy measures.
