Air Separation Unit ASU-2000 from Japan
Industrial machinery designed to separate atmospheric air into its primary components—nitrogen, oxygen, and argon—through cryogenic distillation involving cooling and liquefaction of air. It falls under HTS 8419.60.5000 as 'other' machinery for liquefying air or other gases, distinct from domestic equipment. This process changes the temperature of air to produce liquid gases for industrial applications.

Import Tips
• Verify compliance with ASME pressure vessel codes and obtain necessary certifications for cryogenic components before import
• Prepare detailed technical specifications and process flow diagrams to support classification under 8419.60.5000 and avoid misclassification as general compressors
