Depends: Is just their headquarters in USA alright, or does their manufacturing have to be outside of China as well?
Well there goes these following big-name companies if you want only manufacture outside of China:
-ASUS (technically a Taiwanese company, but they manufacture in China, check Wikipedia)
-Intel (has manufacturing facilities in China)
Please correct me if im wrong, but this is all coming from the respective companies Wikipedia page lol Too lazy to look up more
