Specialized has never been a "production" company. They have always been an importer and marketing company. Outside of some top level frames, everything they market and sell is imported. Go to their website and you will find a brief history of the company.
Of course, along the way in their travels some components they have sold may have been made in USA, but not many. They do some engineering, design and prototyping work at the Morgan Hill location.
At this time I think Merida has an interest in Specialized operations.
