Wouldn’t assessing at the quarry site for all material both domestic and international be easier?
Assessing at the quarry for all material both domestic and international would make things much easier, however the material that is assessed at the quarry and gets exported rough, could come back finished, and run into the possibility of being assessed twice. To avoid such duplications, there could be paper trails for material that leaves the U.S. rough then returns finished, however it would be a difficult to enforce.
