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
