8504.21.00 - Having a power handling capacity not exceeding 650 kVA
Sub-classifications
Overview
This HTS classification, 8504.21.00, pertains to liquid dielectric transformers that possess a power handling capacity not exceeding 650 kVA. These transformers utilize a liquid insulating medium, such as oil, to manage heat and provide electrical insulation. They are commonly employed in various electrical distribution and power transmission applications where their specific power rating is suitable.
This category is distinguished from its sibling categories by its defined power handling limit. Specifically, 8504.21.00 covers transformers up to and including 650 kVA, whereas 8504.22.00 encompasses transformers with a power handling capacity exceeding 650 kVA but not exceeding 10,000 kVA, and 8504.23.00 applies to those with a capacity greater than 10,000 kVA.
Further subdivisions exist within this category, detailing specific ranges of power handling capacity to allow for more precise classification. These subcategories, including 8504.21.00.20 (not exceeding 50 kVA), 8504.21.00.40 (exceeding 50 kVA but not exceeding 100 kVA), 8504.21.00.60 (exceeding 100 kVA but not exceeding 500 kVA), and 8504.21.00.80 (exceeding 500 kVA but not exceeding 650 kVA), facilitate a granular approach to tariffication based on the transformer's operational power output.
