9902.07.29 - Methyl [[2-chloro-4-fluoro-5[(tetrahydro-3-oxo-1H,3H-[1,3,4]thi- adiazolo[3,4-a]pyridazin-1- ylidene)amino]phenyl]thio]acetate (Fluthiacet-methyl technical) (CAS No. 117337-19-6) (provided for in subheading 2934.99.15)

This HTS code, 9902.07.29, falls under Chapter 99, which designates temporary legislation and special classification provisions. Specifically, this entry covers Fluthiacet-methyl technical, a chemical identified by CAS Number 117337-19-6, which is a methyl ester of a thiadiazolopyridazine derivative. Its inclusion in Chapter 99 indicates that it is subject to specific temporary import restrictions or modifications that are not covered by the general provisions of the main HTS chapters.

Distinguishing this category from its sibling entries, which are primarily live animals in Chapter 01, is straightforward. Chapter 99 codes are distinct from the commodity-based chapters of the HTS. They are reserved for goods that require unique tariff treatment due to policy considerations, trade agreements, or specific regulatory measures, rather than their intrinsic physical properties or material composition as found in the other main chapters.

As this is a leaf node, there are no further subcategories. The classification for Fluthiacet-methyl technical is therefore specific and final under this code, subject to the temporary provisions outlined in Chapter 99. Importers should be aware that the "provided for in subheading 2934.99.15" note signifies that this chemical would ordinarily be classified under a different, permanent HTS code, but for the purposes of temporary trade policy, it is routed through this Chapter 99 designation.
