Import Tips & Compliance
• Verify purity certificates to confirm classification as chemically defined inorganic compound under Chapter 28 Note 1
• Include safety data sheets (SDS) due to strong oxidizing properties; common pitfall is improper hazmat shipping declarations
• Ensure labeling meets EPA requirements if for water treatment use to avoid reclassification
