Best of my knowledge, Kruessler is strictly German and or EU, no plants in North America. Know some persons in various import businesses,and they said it is cheaper to import bulk of most substances, rather than individual packaging.
When one thinks about it, a shipping crate of a certian size, probably holds more bulk powdered detergent, than say trying to fit the same amount already in boxes. Also packages add weight, and take up space.
Matter is easily solved, someone who has these products will have to have a peep at the packets. Because of NAFTA and other things, goods shipped into the United States/North America must be labeled as to where content was made, for tariff purposes.
