Import Tips & Compliance
• Register under TSCA for new chemical import if not on inventory; vinyl chloride is listed but verify
• Use UN-approved cylinders (TC/DOT 1086); inspect for leaks to prevent auto-polymerization
• Avoid bulk liquid shipments over rail if not meeting note (e) solvent criteria
