TThe GSA maintains a list of products which it is ok to use foreign sources on ”Buy America” contracts. They figure that if they can’t source it nobody can. They contact manufacturers and ask them if they can make certain products for the GSA under contract. Money no object. Still can’t find made in American products.
Sometimes I wish they wouldn’t find a source. I installed a bunch of made in America brass hose bibs in a campground. Failure rate of 80%. I called the manufacturer to complain and he sent me a box of 24 by overnight, with a return label so I could replace all 21 of them, and ship them back to him. Only nine of the second batch failed. And, he quite promptly sent me a dozen. The next ones that failed I bought Indian made under a well known international brand name. No failures.
