Sino-Global Shipping America assists foreign companies in navigating the murky regulatory waters of China's marine shipping industry. Through subsidiaries Trans Pacific and Sino-China, the company is a shipping agent for US, Australian, and Hong Kong companies transporting iron ore to China. (Currently, freight forwarding company Beijing Shou Rong is Sino-Global's largest customer, representing more than half of the company's revenues.) Trans Pacific has operations at six ports in China; however, each of the country's 76 ports have different rules. CEO Cao Lei owns more than 70% of Sino-Global Shipping America and Sino-China. Sino-Global Shipping America was founded in 2001.
