Import Tips
• Submit particle size analysis report confirming powder form per subheading note; non-compliant shipments often reclassified
• Use NAICS codes for chemical manufacturing on entry; pair with EPA TSCA certification for catalyst end-use
• Avoid common pitfall of declaring as 'scrap' – unwrought powder incurs different duties than waste/scrap under 7112
