Yahoo Finance is tracking three stocks that could take a hit from US President Donald Trump’s proposal to slap a 20% tax on imports from Mexico.

First up is Constellation Brands (STZ). The company gets a big chunk of its revenue from its Mexican beer brands Corona and Pacifico. Shares are falling on the proposal, bringing its losses since the November 8 US presidential election to about 10%.

Trump’s new proposal isn’t going over well with lawmakers in Washington, D.C. Senator Lindsey Graham (R-SC) tweeted, “Simply put, any policy proposal which drives up costs of Corona, tequila or margaritas is a big-time bad idea. Mucho Sad.”

The automotive sector is another that could take a hit from an import tariff. According to the US Trade Representative’s office, cars were the biggest Mexican export to the US in 2015, totaling $74 billion. General Motors (GM) and Ford’s (F) businesses could suffer if Trump’s proposal were enacted.

Americans could also pay more for guacamole, as Mexico produces nearly one third of the world’s avocados. One company that could be forced to pass along higher prices to its consumers is restaurant chain Chipotle (CMG). Shares are lower in intraday trading.
