The Marketplace Daily Pulse is down today on news that the number of metal containers coming off boats has dropped on the biggest shipping route in the world.

Bloomberg News reports cargo was down 3.8 percent on the Asia-to-U.S. run, during the time period of July through September.

The last time there was a down quarter for that shipping route was late 2009.

Some economists blame slow growth in the U.S. for this, but is it possible that fewer stuff with Made in Name-Your-Asian-Country labels coming in at the ports could be a promising sign for American manufacturing?
