Liquefied Ethane Refrigerant Grade from China
High-purity liquefied ethane used as a refrigerant in industrial cryogenic systems, meeting specifications for low boiling point (-88.5°C). Classified under HTS 2711.19.00.10 as liquefied ethane, separate from common LPGs like propane. Essential for ultra-low temperature cooling in labs and food processing.

Import Tips
• Provide refrigerant grade certificates showing <100 ppm impurities to avoid reclassification as general ethane
• Use ISO tank containers rated for cryogenic liquids; declare exact pressure/temperature conditions on entry documents
• Check for anti-dumping duties from specific origins; common pitfall is missing flash point documentation
