8406.81.10.20 - Stationary steam turbines, condensing type

This HTS category, 8406.81.10.20, specifically classifies stationary steam turbines designed for condensation. These are large-scale machines that convert thermal energy from steam into mechanical energy, typically used in power generation facilities. The defining characteristic is their condensing type operation, meaning they are equipped with a condenser system to convert spent steam back into water, thereby improving efficiency and reducing operational costs.

The primary distinction between this subcategory and its sibling, 8406.81.10.70 ("Other"), lies in the specific design feature of condensation. While both fall under stationary steam turbines with an output exceeding 40 MW, this particular classification is reserved for those units incorporating a condenser. Other steam turbines within the 40 MW output range that do not feature a condenser, or employ different operational principles, would be classified under the "Other" category.

As this is a leaf node in the HTS classification database, there are no further subcategories. Therefore, classification within 8406.81.10.20 is determined by the definitive presence of a condensing system on stationary steam turbines with an output exceeding 40 MW. Importers and exporters should verify that the unit's technical specifications and operational design clearly indicate a condensing function to ensure correct classification.
