A smart meter whose principal function is measuring electricity supply or production remains classified under 902830, even if it incorporates wireless communication for data transmission. The communication capability is ancillary to the metering function. Classification would shift only if the article's principal function were determined to be communication rather than metering, which is rarely the case for utility meters.

Electricity meters from certain origins have been subject to antidumping duty orders in the past. Importers should check the current scope of any active antidumping or countervailing duty orders with the Department of Commerce and CBP before importing, as scope determinations can turn on technical specifications such as meter type, phase configuration, and communication capability.
