Trump spokesman Sean Spicer, discussing the idea with reporters, said a 20 percent tax on annual Mexican imports would raise $10 billion a year, easily funding a border wall estimated to cost between $8 billion and $20 billion. The value of imported goods from Mexico in 2015 was $296 billion. Spicer said 160 other nations already tax imports.
According to the Georgia Department of Economic Development, Mexico is the fourth-largest source of imports to Georgia, with almost $6.1 billion worth of goods in 2014. Top imports include insulated wire, TVs, motor vehicles, refrigerators, freezers, piston engines, lamps and light fixtures.
Mexico is also Georgia’s third-largest export market, with $3 billion in exports in 2014, the latest figure available. Mexico is a key market for Georgia’s peanut and kaolin clay producers, along with various manufacturers.
"There are two ways we would get impacted," Humphreys said. Retailers' and manufacturers' costs would go up on products, parts and supplies imported from Mexico, raising their costs as well as prices paid by customers.
Second, Mexico would likely retaliate with a similar import on U.S. exports to that country, he said. That would raise the cost of U.S. products sold in Mexico, denting demand and possibly hurting jobs at U.S. producers.
