Here are some grocery store items that could be affected by Trump's tariffs. China is responsible for nearly 78% of U.S. vitamin imports come directly from China, which dominates the global production of key vitamins (B1, B3, B7, B12, D3 and K), according to the American Feed Industry Association.

And among the countries of origin for those products, Mexico is the biggest contributor — meaning U.S. consumers could see higher prices for a range of grocery and produce items if President-elect Donald Trump follows through on his l atest threat to impose a 25% tariff on all items brought in across the southern border.
