If the Trump administration taxes imports from Mexico and renegotiates NAFTA, it’s U.S. farmers, restaurateurs, and consumers who will be hardest hit.

The menu at Centro, a popular Mexican restaurant in downtown Raleigh, North Carolina, relies on avocados, lemons, limes, and cheeses like queso fresco and cotija imported from Mexico. Since election day, Centro owner and chef Angela Salamanca, like many restaurateurs across the country, has grown increasingly nervous as she’s watched the Trump administration pursue a hostile stance toward Mexico on issues related to trade.

“Limes go up in price for Cinco de Mayo, and we’ve been able to ride those waves,” Salamanca said on a recent Friday just before the lunch rush. “But if there’s a tax imposed on Mexican products, we’ll be in serious trouble, and not just for our food, for our Mezcal, too. We would have to reconfigure our business. What would our offering be if we couldn’t have access to the necessities of Mexican cuisine?”

Behind Canada, Mexico is the largest supplier of agricultural goods to the United States, selling $21 billion worth of food to Americans in 2015, including $4.8 billion in fresh vegetables, $4.3 billion in other fresh fruit, $2.7 billion in wine and beer, and $1.4 billion in processed fruit and vegetables.

Because U.S. agriculture is so intertwined with the Mexican economy, the U.S. has a lot to lose in a trade war. As do American eaters: A full 93 percent of the Hass avocadoes in the U.S. come from Mexico, as well as 71 percent of the tomatoes and 15 percent of the sugar. Additionally, the U.S. imports 79 percent of its neighbor’s exported tequila.

Nevertheless, the Trump administration is taking an aggressive stance toward its southern neighbor. In addition to consistently expressing his intention to build a wall along the U.S.-Mexico border and strengthening the power of federal agents to deport undocumented immigrants, the administration appears committed to assaulting the country economically as well.

Days after his inauguration, the Trump team floated the idea of a 20 percent tax on imports from Mexico as a way to pay for the wall. House Republicans have proposed a different idea, a “border-adjustment” tax on imports. (Without an accompanying export tax, economists say the plan is likely not legal by World Trade Organization rules.)
