Import Tips
• Provide BET surface area analysis (>100 m²/g typical) to prove catalyst-grade purity for Chapter 28 classification
• Declare nanoparticle status on commercial invoice; pitfall is reclassification as waste if recycling content exceeds 5%
• Comply with EPA catalyst import regs; use anti-static packaging to prevent aggregation during transit
