8501.64.01.10 - For wind-powered generating sets classified within 8502.31.00

This HTS classification covers AC generators, also known as alternators, specifically those with an output capacity exceeding 750 kVA. These are high-power generating units designed to convert mechanical energy, typically from a prime mover like a turbine, into alternating current electrical energy. The defining characteristic for inclusion in this category is their significant power output, making them suitable for large-scale industrial applications, power plants, or substantial backup power systems.

The distinction from other AC generator categories lies directly in this power rating. While other subheadings might cover AC generators of lower output, this specific code targets only those that surpass the 750 kVA threshold, indicating a substantial scale of operation and design. It is important to note that this category excludes AC generators that are part of a complete generating set already classified elsewhere, such as wind-powered generating sets.

As a leaf node, this classification does not have further subdivisions. Therefore, classification within this code hinges on confirming the AC generator's output rating meets or exceeds 750 kVA and that it is not a component of a pre-classified generating set. Practical classification will involve examining technical specifications and nameplate data to verify the kVA output.
