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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by its ketone precursor structure
Oxygen-function compounds in 2914 may take precedence if peroxide function secondary to carbonyl group.
If imported as diluted technical grade for bulk industrial blending
Prepared chemical binders or mixtures fall under Chapter 38 when not meeting pure compound criteria.
If specifically listed as hydrogen peroxide derivative rather than 'other'
More specific subheadings within 2909 take precedence over general 'other' category.

Import Tips & Compliance
• Declare concentration levels as peroxides above 70% concentration trigger special UN hazardous packaging
• Include end-use certificates proving industrial chemical application to avoid Chapter 36 fuel classification
• Verify solvent content doesn't render it 'particularly suitable for specific use' per Chapter 29 note (e)
