Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as saturated peroxyacid derivative
Peroxides of acyclic/saturated acids classify in preceding heading 2915, not aromatic 2916.
If when pre-formulated as supported catalyst on inert carrier
If for alcohol peroxides without carboxylic acid functionality
Pure alcohol-derived peroxides classify by alcohol parent structure in heading 2909.

Import Tips & Compliance
• Mandatory DOT/UN hazmat declaration (Class 5.2 organic peroxide) with proper stabilization certification
• Temperature data loggers required for shipments; deviations can lead to CBP holds and peroxide decomposition risks
• Confirm active oxygen content (AO%) matches specification to avoid reclassification as diluted preparation
