Import Tips
• Classify based on active oxygen content; test to confirm peroxocarbonate vs. simple carbonate to prevent duty evasion claims
• Hazard class as oxidizer (5.1); ensure DOT-compliant packaging and placarding for US entry
• For pool chemical use, align with EPA pesticide registration if marketed as algaecide
