Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If prepared as diagnostic reagent mixture
Propane blends specifically for lab diagnostics or reagents fall under prepared laboratory chemicals in 3822.
If butanes predominate over propane
Gaseous butane mixtures exceeding propane content shift to 2711.13 classification.
If compressed pure hydrogen discharge byproduct
Pure hydrogen gases from industrial processes are classified separately in 2804, not petroleum gases.

Import Tips & Compliance
• 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
