Related Products under HTS 2909.60.50.00

Di-tert-butyl Peroxide

Di-tert-butyl peroxide is a dialkyl peroxide used primarily as an initiator in free-radical polymerization reactions for producing plastics and elastomers. It falls under HTS 2909.60.5000 as an ether peroxide, chemically defined organic compound within Chapter 29 scope for separate organic peroxides. This classification covers its use in industrial polymer synthesis rather than as a fuel or coloring agent excluded by chapter notes.

Cumene Hydroperoxide

Cumene hydroperoxide serves as an intermediate in phenol and acetone production via the Hock process, functioning as an organic hydroperoxide. Classified under HTS 2909.60.5000 as an alcohol peroxide derivative within Chapter 29's organic compounds scope. Excluded from Chapter 28 as it's not an inorganic peroxide.

tert-Butyl Hydroperoxide

tert-Butyl hydroperoxide (TBHP) is an organic hydroperoxide used as an oxidant in epoxidation reactions and oxidation catalysis. It qualifies for HTS 2909.60.5000 as an alcohol peroxide, fitting Chapter 29's definition of chemically defined organic peroxides with necessary stabilizers for safe transport.

Dicumyl Peroxide

Dicumyl peroxide acts as a crosslinking agent in rubber and silicone elastomer vulcanization processes. Under HTS 2909.60.5000 as an ether peroxide, it's a separate chemically defined compound per Chapter 29 note (a), distinguished from polymer-bound forms.

Lauroyl Peroxide

Lauroyl peroxide functions as a polymerization initiator for acrylic resins and as a bleaching agent in flour milling. Classified in HTS 2909.60.5000 as a diacyl peroxide (ketone peroxide derivative), meeting Chapter 29 criteria for chemically defined organic compounds with transport stabilizers.

2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane

This dialkyl peroxide serves as a high-temperature initiator for crosslinking polyethylene and silane-modified polymers. HTS 2909.60.5000 covers it as a chemically defined ether peroxide, with permitted anticaking stabilizers per Chapter 29 note (f).
