Mexico struck first, vowing to slap tariffs on U.S. products, including pork and sausage, blueberries, cheese and apples.



The last item is a concerning one for the Washington state apple industry; apples are the state's biggest agricultural crop by far.



"Mexico is the No. 1 buyer of Washington apples," Matt Morrison, CEO of the Pacific NorthWest Economic Region, said. "Canada's the No. 2. We are integrated, and this is going to impact us if we don't turn it around."



Canada announced its own tariffs on U.S. steel and aluminum, and listed dozens more U.S. products that could have new tariffs as well. The items include yogurt, chocolate, cucumbers, toilet paper, washing machines and lawn mowers.



"We are imposing dollar-for-dollar tariffs for every dollar levied against Canadians by the U.S.," Chrystia Freeland, Canada's foreign affairs minister, said.



"These tariffs are totally unacceptable," Prime Minister Justin Trudeau said. "For 150 years, Canada has been the United States' most steadfast ally."



Morrison pointed out that Washington is the most trade-dependent state in the country.



"It doesn't matter if they're coming from Canada or Mexico -- the price of steel will go up and the price of aluminum will go up, and everything else. This is going to have an impact on our economy," Morisson said.



Mary Hernandez said she'll feel the impact at the grocery store.



"It's going to impact each one of us individually," she said, "because what I paid a dollar and a half for this week, I'm going to pay for, two or three dollars, next week."



KIRO 7 contacted Boeing to find out if the new tariffs would affect production.



Boeing responded with a written statement that said it "relies on U.S. suppliers for approximately ninety percent of our end-use aluminum. Because of the way we manage that portion of our supply chain, we do not see these steel and aluminum tariffs as having a material impact on our business, though we continue to evaluate the broader impact of these actions on our suppliers and global trading relationships."
