High-purity ammonia (NH₃) gas supplied from China for chemical synthesis, refrigeration, and industrial processing.
High-purity ammonia (NH₃) for fertilizer production, semiconductor manufacturing, refrigeration systems, and water treatment.
Ammonia is a colorless, toxic, alkaline, and corrosive flammable gas with a characteristic pungent odor. It turns wet red litmus paper blue and forms hydroxide ions in water, exhibiting weak basic properties. Ammonia is easily liquefied under pressure at room temperature (critical temperature: 132.4°C, critical pressure: 11.2 MPa) and readily solidifies into a snow-like solid. It is soluble in water, ethanol, and ether. At high temperatures, ammonia decomposes into nitrogen and hydrogen, displaying reducing properties. Ammonia serves as a critical feedstock for fertilizer production (urea, ammonium nitrate), a specialized gas for semiconductor manufacturing (nitridation, CVD processes), a refrigerant in industrial cooling systems, and a reagent in water treatment and chemical synthesis. It is typically transported as a liquefied compressed gas under pressure.
Global Shipping & Export Compliance
Ammonia (UN 1005) is classified as a toxic and 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 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, corrosive, and flammable gas handling
