Import Tips
• Retain brand-specific technical data sheets showing TBBS composition to support classification during verification audits
• For bulk imports (>25kg drums), ensure DOT/UN packaging certification; avoid plastic bags that risk dust contamination
• Watch for origin marking requirements - chemical name must appear on drums alongside country of manufacture
