Import Tips
• Require supplier certificates of analysis (COA) specifying particle size and silicon-graphite ratio for customs verification
• Label shipments clearly as 'battery anode material - not finished electrodes' to prevent Chapter 85 misclassification
• Comply with REACH-like regulations for nano-materials; prepare for TSCA import notifications in the US
