Brazed Aluminum Plate-Fin Heat Exchanger for Cryogenic Air Separation
This heat exchanger uses brazed aluminum plate-fin construction to efficiently transfer heat in cryogenic air separation plants, enabling the separation of oxygen, nitrogen, and other gases through precise temperature control. It falls under HTS 8419.50.10.00 as a specialized heat exchange unit designed for industrial cooling processes involving phase changes.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of a complete cryogenic distillation plant
Parts of machines for separating air into components fall under 8479 when not standalone heat exchangers.
If made primarily of steel rather than aluminum
Steel plate-fin heat exchangers are classified separately from brazed aluminum types.
If imported as replacement parts rather than complete units
Parts of heat exchange units have distinct provisions outside the specific brazed aluminum subheading.

Import Tips & Compliance
• Verify pressure ratings and certifications like ASME for brazed joints to meet industrial safety standards
• Include detailed engineering drawings and material specs (e.g
• aluminum alloy grade) in documentation to avoid reclassification
• Check for anti-dumping duties on aluminum heat exchangers from specific origins like China
