High-purity hydrogen chloride (HCl) gas supplied from China for chemical synthesis, electronics manufacturing, and industrial processing.
High-purity hydrogen chloride (HCl) for semiconductor etching, pharmaceutical synthesis, metal processing, and water treatment applications.
Hydrogen chloride is a colorless, non-flammable, corrosive gas with a strong, pungent odor. As a hydrogen halide, it is heavier than air and produces dense fumes in humid air due to its strong water solubility, forming hydrochloric acid. HCl serves as a critical raw material for producing chlorides, pharmaceuticals, and agrochemicals, as a specialized etching and cleaning gas in semiconductor manufacturing, for metal pickling and surface treatment, and in water treatment applications. It is also used in the production of vinyl chloride and various organic and inorganic compounds, typically transported as a liquefied compressed gas.
Global Shipping & Export Compliance
Hydrogen chloride (UN 1050) is classified as a toxic and corrosive 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 Hydrogen Chloride 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 Hydrogen Chloride 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 corrosive gas handling
