An article in Bloombergbusinessweek (June 25, 2012) describes several examples of companies that moved production to the US from China, despite up to 30% lower Chinese manufacturing costs. For Lightsaver, the 30% lower manufacturing costs were compensated by costs of coordination and quality issues, making US manufacturing 2 to 5% cheaper. For Ultra Green Packaging, intellectual property concerns caused the move back to the US. For Unilife, a maker of syringes preloaded with medicine, moving to the US ensured lower costs to ensure FDA compliance. Given these examples, how much should costs in China drop below US costs to justify making products there ? Will manufacturing in China be for their markets or will intellectual property concerns justify importing to satisfy Chinese demand ? Are these moves to the US the result of dropping US wages too ?
