Woes at Hanjin Shipping, South Korea's largest sea container shipping firm and the world's seventh-biggest with a 2.9 per cent market share, are derailing the supply chains of companies that need to send goods well in advance of the year's biggest shopping season as Thanksgiving and Christmas holidays approach. TVs, cars and trainers sail about 10 days to reach Los Angeles from Asia while they could take as many as 30 days to Rotterdam. Hanjin Shipping owns 59 of the 132 container and bulk ships in its fleet.
