Chipotle has new sources of avocados in Colombia and Peru, its CEO said. But the chain might still take a hit from Trump's potential Mexico tariffs.

Chipotle Mexican Grill said Tuesday that it does not expect costs to rise much if tariffs on key imported ingredients go into effect next month, noting that only about half of its avocados come from Mexico.

Mexico supplies upwards of 90% of the avocados Americans eat, and President Donald Trump is likely to make them more expensive with his plan to slap 25% tariffs on Mexican imports beginning on Saturday.
