Electrical Energy

Electrical energy imported into the United States — primarily via high-voltage transmission interconnects — is classified under a single tariff line (2716000000) and is unique among Chapter 27 commodities in that it is measured in kilowatt-hours rather than weight or volume. Canada is the sole recorded foreign supplier, consistent with the physical reality that cross-border electricity trade requires direct grid interconnection. Imports are subject to oversight by the Department of Energy and the Federal Energy Regulatory Commission, and transmission arrangements are governed by bilateral agreements and grid reliability standards rather than conventional customs entry procedures.
