High-purity deuterium (D₂) gas supplied from China for research, nuclear applications, and specialty chemical synthesis.
High-purity deuterium (D₂) for isotopic labeling, neutron moderation, semiconductor manufacturing, and advanced research.
Deuterium is a heavier, stable isotope of hydrogen, consisting of one proton and one neutron in its nucleus. It is a colorless, odorless, non-toxic, and flammable gas. As a diatomic molecule, it exists in ortho and para spin isomers, with a 2:1 equilibrium composition at room temperature. Deuterium serves as a critical material in nuclear research and neutron moderation, a tracer for isotopic labeling in biochemical and environmental studies, a feedstock for producing heavy water and deuterated compounds, and a specialized gas in semiconductor and fiber optic manufacturing. It is also used in advanced scientific research, including neutron scattering experiments and fusion energy studies, typically transported as a liquefied compressed gas.
Global Shipping & Export Compliance
Deuterium (UN 1957) 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 Deuterium 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 Deuterium 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
- Not specifying the required purity for isotopic applications
