High-purity propane (C₃H₈) gas supplied from China for clean energy, industrial processing, and specialty applications.
High-purity propane (C₃H₈) gas for fuel gas, refrigerant, aerosol propellant, and petrochemical feedstock applications.
Propane is a colorless, odorless low-carbon alkane widely found in natural gas and petroleum. As a clean-burning energy source, it is liquefied under moderate pressure for efficient storage and transport. Propane serves as a versatile fuel for heating, cooking, and vehicles, as a refrigerant in low-temperature systems, as an aerosol propellant, and as a petrochemical feedstock for producing propylene and other chemicals. Its high purity and stability make it suitable for both industrial and specialized applications, typically transported as a liquefied compressed gas.
Global Shipping & Export Compliance
Propane (UN 1075) is classified as a flammable compressed gas and must be handled under strict hazardous materials regulations.
- Sea freight (FCL / LCL) – standard export method (including ISO tanks)
- Air freight – limited availability (regulatory controlled)
Required Export Documents
- Material Safety Data Sheet (MSDS)
- Certificate of Analysis (COA)
- Dangerous Goods Declaration (DGD)
- UN-certified cylinder documentation
- Commercial invoice & packing list
How to Order Propane Gas from China
- Send technical requirements (purity, cylinder specification, application)
- Receive quotation (EXW / FOB / CIF options)
- Confirm cylinder specification & compliance
- Review COA, MSDS, and certification documents
- Production, filling, and quality inspection
- Hazardous goods shipping arrangement
- Delivery and final inspection at destination
Common Mistakes When Buying Propane Gas
- Choosing suppliers only based on lowest price
- Ignoring cylinder certification and pressure rating
- Not verifying moisture and impurity levels
