Import Tips
• Include Safety Data Sheets (SDS) and CAS registry numbers to confirm chemical identity and prevent reclassification
• Verify alkyl chain compliance (O-alkyl ≤C10, dialkyl limited to methyl/ethyl/n-propyl/isopropyl) through NMR or GC-MS analysis
• Watch for CWC dual-use concerns; may require Commerce Department export license validation for import
