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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by saturated acyclic structure rather than peroxide function
Saturated acyclic monocarboxylic acids and derivatives could apply if acid function dominates, per Chapter 29 ester/salt classification notes.
If when imported as a stabilized mixture for safety/transport
Chapter 29 excludes preparations; mixtures with stabilizers may fall under prepared chemical products if additions render it suitable for specific use.
If for hydrates or aqueous solutions exceeding safety/transport limits
Chapter 28 covers certain hydrides/oxides; aqueous peroxides might classify there if not meeting Chapter 29 solvent dissolution notes.

Import Tips & Compliance
• Obtain proper SDS and UN certification for hazardous peroxides; ensure packaging meets DOT/UN explosive/peroxide transport standards
• Verify chemical purity documentation to confirm classification as chemically defined compound under Chapter 29 note (a)
• Avoid misclassification as mixtures by ensuring no added stabilizers exceed Chapter 29 note (f) allowances
