Costco is an American company but brings in well marked international products. I got lettuce from Canada, Raspberries from Mexico and Brocoli from South America. All 3 of those products were American at my local store.
Costco has stood up to the culture war in US, with refusing to back down on DEI hiring as a middle finger to Trump. They are the one American company I am open to continue supporting during this boycott, while making sure not to buy US products.
