High-purity carbon dioxide (CO₂) gas supplied from China for beverage carbonation, welding, and industrial processing.
High-purity carbon dioxide (CO₂) for food and beverage applications, metal fabrication, chemical synthesis, and medical use.
Carbon dioxide is a colorless, odorless gas at room temperature and pressure. As a naturally occurring compound, it is soluble in water and most organic solvents such as hydrocarbons. CO₂ serves as a versatile industrial gas, widely used in beverage carbonation, as a shielding gas in welding, as a raw material for chemical synthesis (including urea and methanol production), and in enhanced oil recovery. High-purity grades are essential for medical applications, semiconductor manufacturing, and laboratory calibration standards. It is typically transported as a liquefied compressed gas in specialized cylinders or bulk tankers.
Global Shipping & Export Compliance
Carbon dioxide (UN 1013) is classified as a non-flammable compressed gas and must be handled under strict hazardous materials regulations.
- Sea freight (FCL / LCL) – standard export method
- Air freight – available with regulatory compliance
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 Carbon Dioxide 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 Carbon Dioxide Gas
- Choosing suppliers only based on lowest price
- Ignoring cylinder certification and pressure rating
- Not verifying moisture and impurity levels (critical for food and beverage applications)
- Skipping third-party inspection before shipment
- Overlooking export documentation compliance
