Summary
HS code 8504.23 covers liquid dielectric transformers, having a power handling capacity exceeding 10,000 kVA. It sits in heading 85.04 (electrical transformers, static converters (for example, rectifiers) and inductors) in chapter 85 (electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles). Other goods of heading 85.04 are classified under 8504.10 (ballasts for discharge lamps or tubes), 8504.21 (liquid dielectric transformers, having a power handling capacity not exceeding 650 kVA), 8504.22 (liquid dielectric transformers, having a power handling capacity exceeding 650 kVA but not exceeding 10,000 kVA), 8504.31 (other transformers, having a power handling capacity not exceeding 1 kVA) or 6 others. National tariff lines under 8504.23 are live on border.bot for the United States (3 lines, also used by 1 other country).
