Import Tips & Compliance
• Certify particle size distribution to distinguish from standard powders and avoid reclassification
• Label shipments clearly as 'inorganic pigment raw material' to prevent confusion with Chapter 69 ceramics
• Check for REACH-like compliance if transshipping from EU; TSCA pre-notice may apply
