The city handled a total of 211.5 million tonnes of dry bulk goods, a 24.8 percent advance from the same period a year ago, the Shanghai Daily reported.
Waigaoqiao port remains the busiest port in the country with dry bulk cargo throughput climbing 16.5 percent to 67.4 million tonns. Container volume was up 13.5 percent to reach 7.2 million TEUs over the first six months.
Container throughput at the Yangshan Deep-Water Port rose 30.6 percent to 4.7 million TEUs after the Shanghai government's preferential policies attracted shipping companies to use the port as a transfer hub.
"Growth at domestic ports in the second half may not be as strong as the first half and in the long run the growth rate will be between 10 to 15 percent," Bank of China International's Du Jianping wrote in a report.
"Government policies as well as the economic situation of surrounding markets will also have an impact on their performances," he added.
