Import Tips
• Verify purity levels and provide chemical composition certificates to confirm classification as a chemically defined cerium compound per Chapter 28 notes
• Ensure SDS (Safety Data Sheets) comply with HAZMAT regulations, as cerium oxide may require special handling during import
• Avoid misclassification as a glass polishing mixture (heading 3208) by documenting its use as a pure chemical compound
