8501.63.01.00 - Of an output exceeding 375 kVA but not exceeding 750 kVA

This HTS classification covers AC generators, also known as alternators, specifically those designed to produce an electrical output power greater than 375 kilovolt-amperes (kVA) but not exceeding 750 kVA. These are typically robust electrical machines designed for continuous operation in various industrial, commercial, and utility applications where reliable AC power generation is essential. Examples include medium-sized standby generators for commercial buildings, primary power sources for smaller industrial plants, or backup units for critical infrastructure.

Distinguishing this category from its siblings is crucial for accurate classification. HTS code 8501.61.01.00 covers alternators with outputs up to 75 kVA, while 8501.62.01.00 addresses those between 75 kVA and 375 kVA. Conversely, HTS code 8501.64.01 encompasses alternators with outputs exceeding 750 kVA. Therefore, the defining characteristic of 8501.63.01.00 is its specific output power range of 375 kVA to 750 kVA.

As this classification represents a leaf node within the HTS, there are no further subcategories to introduce. The classification is finalized at this level based on the specific output capacity of the AC generator. When encountering goods under this category, meticulous verification of the manufacturer's stated output rating is paramount to ensure correct customs declaration.
