The South Korean court overseeing Hanjin Shipping Co.’s receivership is considering a sale process for the entire container line, a month after the debt-laden company’s filing roiled supply chains worldwide.

Hyundai Merchant Marine Co., South Korea’s second-largest container line, surged in Seoul trading after the company was said to be looking at some assets of troubled rival Hanjin Shipping Co. for a possible acquisition.

Hanjin Shipping Co. and its customers are being asked to pay more than usual to bring freight into U.S. ports, creating a backlog that could keep goods off shelves during the holiday shopping season.

Hanjin Shipping Co. won’t allow containerships anchored at sea to complete their journeys to the United States, according to an e-mail obtained by Transport Topics.

Korea Development Bank, the main lender to Hanjin Shipping Co., offered a conditional credit line of 50 billion won ($45 million) to help ease supply chain disruptions caused by the collapse of the nation’s biggest container mover.

LOS ANGELES — For the past five years, top shipping companies pushed forward with fat investments in more and bigger vessels, even as signs of trouble piled up.

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.

Hanjin Shipping Co., the South Korean container line that sought bankruptcy protection last month, received a court advisory to return all chartered vessels to cut costs while the company is in the midst of reducing its fleet.

Cargo stranded by the Hanjin Shipping bankruptcy slowly began to flow through U.S. ports last week, offering the first small signs of relief for truckers and their customers.

As Hanjin Shipping vessels finally arrive in the United States, some motor carriers are reluctant or refusing to accept cargo that might have been damaged because it could expose them to liability claims.
