jonkay1, these have been in production for some time now. Please read the GT description carefuly....

These tubes do have 'high U.S. content'.....but are finished in China. GT doesn't clue you into the China build aspect...but that 'high U.S. content' is the key to understanding that the tubes are not total U.S. manufacture. There is no manufacturing facility in the U.S. that can do the hazardous metals due to the expense of EPA demands.
