Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If power handling capacity does not exceed 10,000 kVA
Lower capacity transformers fall into the preceding subheading with different duty treatment.
If imported as core or coil assembly without full enclosure
Incomplete transformers classified as parts rather than complete units.
If power handling exceeds 60,000 kVA
Higher capacity liquid dielectric transformers use the subsequent statistical suffix.

Import Tips & Compliance
• Obtain IEEE/ANSI certification and test reports verifying power rating and dielectric fluid specifications to avoid reclassification
• Declare exact kVA capacity on commercial invoice; discrepancies can lead to penalties as capacity determines subheading
• Check EPA regulations for PCB-free insulating oil; provide Material Safety Data Sheets for customs clearance
