alt Hacker NewsThe US production in your linked article is listed as "W". This is explained as "Withheld to avoid disclosing company proprietary data". But imports consistently exceed exports, so it appears that US production is not likely to make up a global shortfall.
Until the cost of local production (union labor, environmental regulations, etc.) meets the increasing costs of imports during said shortfall. Then we'll just make it here. The shortfall goes away but the price would admittedly be higher.
