This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If power capacity is 500 kVA to 10,000 kVA
Same liquid dielectric design but smaller capacity moves it to the lower power handling subheading.
If dry-type/air-cooled construction
Dry-type transformers without liquid dielectric are classified under the air-cooled subheading regardless of size.
If imported as core/coil assembly without tank or oil
Unfinished transformer parts or assemblies lacking complete liquid dielectric enclosure fall under parts heading.

Import Tips & Compliance
• Obtain NEMA certification and provide detailed test reports on oil dielectric strength and BIL ratings for customs clearance
• Declare exact MVA rating and voltage class; under-declaring capacity risks reclassification and penalties
• Ensure shipping manifests specify 'liquid-filled' to avoid confusion with dry-type transformers
