Products classified under HTS 2909.60.20.00
Cumene Hydroperoxide
Cumene hydroperoxide is an aromatic ketone peroxide used primarily as an initiator in polymerization reactions for producing polystyrene and other resins. It falls under HTS 2909.60.20.00 as an aromatic ketone peroxide, chemically defined with the peroxide group characteristic of this heading. The 'Other' subheading applies since it is not specifically enumerated elsewhere in the aromatic peroxides category.
tert-Butyl Peroxybenzoate
An aromatic ether peroxide used as a curing agent in polyester resins and rubber vulcanization. Classified under HTS 2909.60.20.00 due to its aromatic structure with ether-peroxide functionality. Meets Chapter 29 requirements for chemically defined organic peroxide derivatives.
p-Menthane Hydroperoxide
Aromatic ketone hydroperoxide derived from p-cymene, used in silicone rubber curing and paint driers. Falls under HTS 2909.60.20.00 as an 'Other' aromatic peroxide meeting Chapter 29 chemically defined compound criteria. The aromatic ring structure qualifies it for this specific subheading.
Benzyl tert-Butyl Ether Peroxide
Aromatic ether peroxide used in low-temperature polymerization initiators. HTS 2909.60.20.00 classification reflects its aromatic ether-peroxide structure as a chemically defined derivative per Chapter 29 scope. 'Other' category captures specialized industrial peroxides.
Di(cumyl) Peroxide
Bis(1-methyl-1-phenylethyl) peroxide, an aromatic dialkyl peroxide used in crosslinked polyethylene production. Classified HTS 2909.60.20.00 as aromatic ketone peroxide derivative, chemically defined organic compound per Chapter 29 note (a). High-purity technical grade qualifies.
