Mexican President Claudia Sheinbaum on Tuesday said Mexico will take action if an agreement with Washington regarding new tariffs is not reached by the August 1 deadline set by her U.S. counterpart Donald Trump.

While Mexico was spared from Trump's so-called "Liberation Day" tariff rollout on April 2, the 30% rate for the E.U. is 10 percentage points higher than what the president said he would apply to America's largest trading partner in April but lower than his mid-May threat of 50%.

A 17% import tax has been slapped on most fresh Mexican tomatoes. Proponents of the tariffs say it’ll help rebuild the shrinking tomato industry in the United States, but experts say prices will go up as much as 10% at the store in the meantime.

Businesses typically pass tariff costs onto consumers through higher prices. Sometimes, that process is less subtle.

In the wake of new tariffs, the San Diego Regional Chamber of Commerce announced Monday that its senior leadership met with U.S. Ambassador to Mexico Ronald Johnson and emphasized the importance of a stable trade relationship between Mexico and the United States.

The U.S. government said Monday it is placing a 17% duty on most fresh Mexican tomatoes, after negotiations over alleged unfair trade practices ended without an agreement to avert the tariff.

If a 30 percent tariff on Mexico goes into affect on August 1, a wide variety of foods will be more expensive, experts warn.
