DOE energy conservation standards for residential dishwashers cover standard-size and compact dishwashers, with separate energy and water consumption limits for each class. Countertop and portable models that meet the definition of 'compact' dishwashers are subject to the compact-class standards rather than the standard-size thresholds. Importers should confirm which DOE product class applies to their specific model before certification.

While CBP does not routinely require DOE certification documents at the port of entry, importers should maintain on file the DOE certification report, test data, and the model's listing in the CCMS database. DOE and FTC can conduct post-market surveillance, and failure to produce compliance records on request can result in enforcement action. Including the certified model number on commercial invoices also helps avoid classification disputes.
