9 to 5 Mac had a nice little write-up about what "Assembled in America" means to the FTC and when it can be used.
The FTC says that "Assembled in American" can only be used when a "substantial transformation" has occurred, not just the final assembly of foreign-sourced components.
Personally, I think this has to do with the friction welding process that the new iMac is using. This was also reportedly the cause of the delay in the release. Is it really much of a stretch to think that China couldn't meet the demand for such a new and advanced assembly method and some production shifted to the U.S. as a result? This would also satisfy the FTC's requirements, since the chassis construction along with assembly would constitute a "substantial transformation".
