2909.60 - Alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides, ketone peroxides and their halogenated, sulfonated, nitrated or nitrosated derivatives:

This HTS category, 2909.60, encompasses a specific group of organic peroxides. It covers alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides, and ketone peroxides. These compounds are characterized by the presence of an oxygen-oxygen single bond within their molecular structure, which imparts reactive properties. The description also includes derivatives of these peroxides that have been modified by the addition of halogen, sulfo, nitro, or nitroso groups.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike the ether classifications (2909.10 through 2909.50), which primarily deal with oxygen linking two carbon atoms, 2909.60 specifically addresses peroxides, where oxygen atoms are linked to each other. This fundamental structural difference dictates the chemical behavior and applications of the substances classified here.

Within this category, the primary subclassification distinguishes between aromatic peroxides and other types. The subcategory "2909.60.50.00: Other" captures any peroxide compounds falling under the broad description of 2909.60 that are not specifically classified as aromatic. This often includes aliphatic or cyclanic peroxide structures and their modified derivatives.
