Import Tips
• Label packages with UN hazard class 5.1 (oxidizer) and ensure DOT-compliant shipping documentation
• Provide assay certificates proving >98% purity to avoid reclassification as a preparation under 3824
• Check state-level restrictions on hexavalent chromium; pitfall is failing to declare for superfund reporting
