8504.33.00 - Having a power handling capacity exceeding 16 kVA but not exceeding 500 kVA

This HTS category, 8504.33.00, encompasses electrical transformers that have a power handling capacity within a specific mid-range. Specifically, these transformers are designed to operate with a power output greater than 16 kVA but not exceeding 500 kVA. This range excludes smaller transformers classified under 8504.31 and those with a capacity exceeding 1 kVA but not exceeding 16 kVA, which fall under 8504.32.00.00. Furthermore, it is distinct from transformers with higher power ratings, classified under 8504.34.00.00.

The key differentiator for goods within this heading is their power handling capacity, measured in kilovolt-amperes (kVA). While the general description at the parent level covers "other transformers," this specific sub-heading refines the classification based on the magnitude of electrical power they are designed to manage. This range is typically associated with industrial or commercial applications where medium-level power transformation is required, distinguishing them from smaller units used in consumer electronics or very large units found in power generation or distribution substations.

Within this category, further subdivisions exist to provide a more granular classification. These subcategories, 8504.33.00.20 and 8504.33.00.40, further refine the power handling capacity range. 8504.33.00.20 specifically covers transformers with a capacity exceeding 16 kVA but not exceeding 50 kVA, while 8504.33.00.40 addresses those exceeding 50 kVA but not exceeding 500 kVA. This detailed breakdown allows for more precise trade data collection and tariff application based on the specific power output capabilities of the transformers.
