High-purity ethane (C₂H₆) gas supplied from China for chemical feedstock and refrigerant applications.
High-purity ethane (C₂H₆) gas for ethylene production, steam cracking, metallurgical heat treatment calibration, and refrigeration systems.
Ethane is a colorless, odorless, and flammable gas under standard conditions. It is insoluble in water, slightly soluble in ethyl alcohol and acetone, and soluble in benzene. As a key alkane, it forms explosive mixtures with air and reacts vigorously with fluorine and chlorine. In the chemical industry, ethane is primarily used as a feedstock for producing ethylene, vinyl chloride, and other petrochemicals via steam cracking. It also serves as a refrigerant in cryogenic facilities and as a calibration standard for heat treatment processes in the metallurgical industry, typically transported as a liquefied compressed gas.
Global Shipping & Export Compliance
Ethane (UN 1035) is classified as a flammable compressed gas and must be handled under strict hazardous materials regulations.
- Sea freight (FCL / LCL) – standard export method
- 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 Ethane Gas from China
- Send technical requirements (purity, pressure, 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 Ethane Gas
- Choosing suppliers only based on lowest price
- Ignoring cylinder certification and pressure rating
- Not verifying moisture and impurity levels
- Skipping third-party inspection before shipment
- Overlooking export documentation compliance
