High-purity nitrogen dioxide (NO₂) gas supplied from China for chemical synthesis, industrial processing, and environmental applications.
High-purity nitrogen dioxide (NO₂) for chemical intermediate production, wastewater treatment, and specialty gas applications.
Nitrogen dioxide is a yellow-green toxic gas with a strong, irritating odor. As a nitroxide compound, it is chemically very reactive due to its free radical nature. It is insoluble in water at ambient conditions but reacts with water to form nitric acid. NO₂ readily reacts with oxygen to form corrosive gases and serves as a key precursor in the production of nitric acid, various nitrates, and other chemicals. It is also used in wastewater treatment, as a bleaching agent, and as a specialty gas for various industrial processes. The gas is typically transported as a liquefied compressed gas.
Global Shipping & Export Compliance
Nitrogen dioxide (UN 1067) is classified as a toxic 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 Nitrogen 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 Nitrogen Dioxide 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
- Underestimating safety requirements for toxic and reactive gas handling
