Import Tips
• Temperature control documentation required for peroxide thermal stability during ocean transport
• Classify with proper CAS number (75-91-2) and confirm <72% concentration for non-explosive shipping
• Prevent reclassification as waste under Chapter 38 by providing manufacturer purity certificates
