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
