Import Tips
• Request C.I
• Constitution Number (C.I. 12460) documentation from manufacturer to match exact HTS subheading
• Declare particle size distribution (typically 0.1-0.2 microns) as it affects dispersion but not classification
• Watch for anti-dumping duties if sourced from specific Asian producers; check Commerce scope rulings
