Import Tips
• Verify purity and chemical composition via lab analysis to confirm classification as chemically defined strontium hydroxide per Chapter 28 notes
• Include Safety Data Sheets (SDS) and Certificates of Analysis in documentation to comply with TSCA and DOT hazardous material regulations
• Avoid misclassification as organic compounds; ensure no organic stabilizers exceed incidental levels to prevent reclassification
