Overview

This HTS category, HTS Code 9902.06.66, specifically classifies Uniconazole-P, a plant growth regulator identified by CAS No. 83657-17-4. This substance, chemically described as (4Z)-5-(4-Chlorophenyl)-2,2-dimethyl-4-(1H-1,2,4-triazol-1-yl)-4-hexen-3-ol, is temporarily provided for under this special provision, with its permanent classification falling under subheading 2933.69.60. The inclusion in Chapter 99 signifies a temporary trade measure or restriction.

Given that this is a leaf node, there are no further subdivisions. The classification is highly specific to Uniconazole-P itself. Therefore, distinguishing it from siblings at the same level involves recognizing that all other entries within Chapter 99 relate to distinct temporary legislative provisions, trade agreement modifications, or Section 22 restrictions on agricultural imports. Unlike the broad categories of live animals found elsewhere in the HTS (e.g., Chapter 01), this node addresses a singular chemical compound designated for special import treatment.
