In 2022, the U.S. imported approximately 18 metric tons of gallium (note Indium use doubled 2022 to 2023) so expect the same for gallium

China produced 600 tonnes of Gallium in 2022.

The scrap Indium corp plan to recover also has 20% Indium which is also a high value metal.

In 2023, the United States consumed an estimated 300 metric tons of indium, marking a nearly 50% increase from the previous year.

Then of course you have the scrap from other countries, scrap that would otherwise be worthless. Japan, Korea, Taiwan for starters would be high consumers.
