8406.82.90.00 - Other

This HTS category, 8406.82.90.00, is designated for "Other" turbines within the broader classification of steam turbines and other vapor turbines. Specifically, it encompasses vapor turbines that are not explicitly classified under sibling categories, such as steam turbines, and are further defined by their output not exceeding 40 MW. This residual category is crucial for capturing all vapor turbines within this output range that do not fit into more specific subheadings.

Unlike the sibling category 8406.82.10, which exclusively covers steam turbines, this category 8406.82.90.00 is intended for other types of vapor turbines. This distinction would typically be based on the working fluid used, with "steam turbines" referring to those powered by steam and this "other" category encompassing turbines driven by other vapors. The common characteristic is their power output, which must not exceed 40 MW for inclusion in this grouping.

As this is a leaf node, there are no further subcategories to introduce. Therefore, the classification of goods under 8406.82.90.00 relies heavily on the precise definition of what constitutes "other" vapor turbines. This could include turbines powered by organic fluids, refrigerants, or other vaporized substances, provided they are designed for mechanical drive and their rated output is within the 40 MW limit. Proper documentation, such as technical specifications detailing the working fluid and power generation capacity, is essential for accurate classification.
