Import Tips
• Provide NIST-traceable certificates of analysis confirming 90% minimum purity to satisfy CBP verification
• Label cylinders with exact composition and use SDS compliant with OSHA HazCom standards
• Avoid common pitfalls by segregating from fuel propane during storage to prevent cross-contamination claims
