Import Tips & Compliance
• Label containers with UN 3025 (Butylene oxide) markings and ensure secondary containment for spill prevention
• Confirm no sulfonation or halogenation occurred during synthesis, as modified derivatives stay with parent per chapter notes
• For bulk imports, arrange bonded warehouse storage to manage duty suspension during processing
