Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically enumerated cumene-derived peroxides
More specific statistical suffixes exist; 'Other' applies only when not precisely matching principal cumene products.
If masterbatch with polymer carrier
Polymer-bound peroxides classify as compound preparations under Chapter 38.
If high boiling petroleum distillate solution
Solvent-based if solvent imparts specific use characteristics per Chapter 29 note (e)

Import Tips & Compliance
• Provide peroxide value assay (meq O2/kg) confirming active oxygen content for classification
• Use Type F organic peroxide packaging; shock/watch required for transport declarations
• Avoid water contamination; peroxides hydrolyze and lose efficacy
