It looks as though Apple may be bringing back some of its manufacturing to the United States. On some of the new iteration of iMacs users are finding that the label says "Assembled in the USA." To earn that tag, the FTC requires a product to undergo its last "substantial transformation" in the United States.
These means that the system can't just have a part screwed on, such as a stand, in the United States to earn that label. So, Apple is either stretching the truth, in which case they could be sued by the FTC, or Apple is actually doing a large portion of the iMac's manufacturing in the United States.
DigitalTrends points out that Apple could be doing a limited run here in the United States and will be sending what it learns over to China for mass production. However, some will remember that Tim Cook said, back in May, that Apple wants more Apple products to be made in America. "We will do as many of these things [in America] as we can do and you can bet that we'll use the whole of our influence to do this."
