Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If actually zinc oxide (ZnO), not peroxide
Zinc oxide specifically provided for in 2817; peroxides remain in 2825.
If when medicated for retail therapeutic use
Medicinal preparations containing zinc peroxide shift to Chapter 30.
If as disinfectant put up for retail sale
Retail disinfectants excluded from Chapter 28 per chapter notes.

Import Tips & Compliance
• Ensure packaging prevents moisture absorption, which destabilizes peroxides; include stability test reports
• Hazardous material declaration required (UN 1516); proper placarding avoids delays
