Import Tips
• Verify purity certificate (typically >99%) to confirm classification as chemically defined cerium oxide under Chapter 28 notes
• Include safety data sheets (SDS) for oxidizing properties; common pitfall is mislabeling as general rare-earth mixture
• Check REACH/ TSCA compliance for US entry; bulk shipments require proper ventilation to prevent dust hazards
