Beginning June 29, 2022, aluminum imports requiring an Aluminum Import license will require the declaration of "country of largest smelt" and "country of second largest smelt."

The U.S. Commerce Department defines the field for the country of smelt for the largest (and second largest) volume of primary aluminum as the country where the largest volume of new aluminum metal is produced from alumina (refined aluminum oxide) by the electrolytic Hall-Héroult process.
