The National Retail Federation and other U.S. trade groups are urging the Commerce Department to work with the South Korean government to resolve the Hanjin Shipping Co. crisis, which stranded an estimated $14 billion of goods at sea, Bloomberg News reported yesterday. Last month’s bankruptcy of Hanjin, which moves huge containers of products to the U.S. from Asia, has roiled supply chains and delayed shipments of everything from T-shirts to televisions. Companies are concerned that their goods may be seized by Hanjin’s creditors once the ships dock, the organizations wrote in a letter to Commerce Secretary Penny Pritzker.
