Import Tips
• Document anti-dusting agent type (fumed silica) and concentration (<0.5%) to qualify under Chapter 29 note (g)
• Conduct sieve analysis (dust <1% through 325 mesh) to verify anti-dust effectiveness
• Segregate from pure grades to prevent cross-contamination in multi-product facilities
