Surface Condenser for Steam Turbine Power Plant

A large shell-and-tube heat exchanger designed to condense exhaust steam from a steam turbine in a power generation facility by cooling it with circulating water. It falls under HTS 8404.20.00.00 as a condenser specifically for steam power units, auxiliary to boilers in headings 8402 or 8403. The low-pressure exhaust steam is condensed into water for reuse in the boiler cycle.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

8419.50.50Lower: 35% vs 40%

If used in nuclear reactor cooling systems

Condensers integral to nuclear reactors are classified under heading 8419 for machinery for isotopic separation or nuclear reactors.

8479.89.65Lower: 20.3% vs 40%

If classified as part of a complete industrial steam power generation machine

Unspecified industrial machinery parts may fall under 8479 if not specifically identifiable as auxiliary to boilers under 8404.

8419.89.95Lower: 39.2% vs 40%

If for heating, ventilation, or air conditioning applications

Heat exchangers functioning primarily for HVAC rather than steam power condensation go to heading 8419.
