Import Tips
• Use precise REO assays (e.g
• 99%+ total rare-earth oxides) to support valuation and avoid undervaluation penalties
• For EU/US imports, check for conflict minerals reporting if sourced from certain regions, though rare-earths are exempt from Dodd-Frank
• Bundle with origin certificates; mixtures from China face Section 301 tariffs—calculate accordingly
