9902.02.40 - 2-Phenyl-2-propanyl hydroperoxide (cumene hydroperoxide) (CAS No. 80-15-9) (provided for in subheading 2909.60.20)

This HTS category, 9902.02.40, specifically classifies 2-Phenyl-2-propanyl hydroperoxide, also commonly known as cumene hydroperoxide (CAS No. 80-15-9). This organic peroxide compound is an important chemical intermediate, often utilized as an initiator in polymerization reactions and as an oxidizing agent in various industrial processes. Its classification within Chapter 99 signifies it is subject to special or temporary trade provisions, often related to import restrictions or trade agreement modifications, and is provided for under the more general subheading 2909.60.20, which covers other organic peroxides, organic hydroperoxides, and their derivatives.

Given that this is a leaf node within Chapter 99, there are no further subcategories to explore under this specific code. The distinction from sibling categories at the HTS Database Root level (e.g., Chapter 01 for live animals) is fundamental, as 9902.02.40 pertains to a specific industrial chemical, not live organisms. The primary classification criterion for this entry is the precise chemical identity and its registered CAS number, ensuring that only cumene hydroperoxide, and not other similar organic peroxides, falls under this particular provision.
