Import Tips & Compliance
• Include conversion yield certificate (>95%) to distinguish from general cerium mixtures
• Label as strong oxidizer (UN 3077); common error is shipping under oxidizing solid class without proper placards
• TSCA registration required; test for nitrate impurities that could trigger 2834 classification
