One really interesting thing about 360 Cookware is that the factory uses green manufacturing practices. We talk more about this below.
The 360 Cookware factory is located in West Bend, Wisconsin. Until recently, their cookware was made 100% in the United States. However, they lost their American source of bonded metal (that is, tri-ply), so they were forced to source it from South Korea.
They also source their single-ply steel (probably for lids) and long handles from China.
Thus, 360 Cookware is no longer 100% made in the USA. You can read more about it on the 360 Cookware website page Where is 360 Cookware Made? (It's an interesting read that goes into a lot of detail about materials and manufacturing processes.)
