American food and drink makers
A map of the food shelves. Two of them are thin so far and have no page of their own yet, which this page says rather than hides.
Coffee and tea
3 makers: 3 made in the USA as claimed. There is no page for this shelf yet, so these are not browsable.
American candy and chocolate makers
5 makers: 3 made in the USA as claimed; 1 made in the USA with a qualifier; and 1 varying by product.
Pantry
7 makers: 5 made in the USA as claimed; 1 from a manufacturer operating in the USA; and 1 varying by product. There is no page for this shelf yet, so these are not browsable.
The ingredient is usually the honest part
Coffee and cocoa do not grow in the continental United States in any commercial quantity. A chocolate maker in Maine and a roaster in Washington are doing real American manufacturing, and the bean in both cases crossed an ocean. The good ones say so.
This is the clearest case on the site where "made in the USA" and "grown in the USA" are different questions, and where only one of them has a plausible answer.
