Import Tips
• Declare exact oxide equivalent (REO) content on commercial invoice, as buyers often specify purity levels for magnet production
• Comply with US Rare Earth Element import tracking; retain supplier affidavits confirming no cerium content to match subheading
• Watch for anti-dumping duties on Chinese origins; use HTS lookup tools and consult CBP for binding rulings on mixtures
