The composite index for coastal bulk freight, which measures transportation costs in the coastal shipping market, stood at 953.42 last month.
The sub-index for coal logged the most notable increase of 1.1 per cent during the month, followed by that for crude oil, a state-controlled news agency reported.
Guided by the transport ministry, the index was started by SSE in 2001 to reflect fluctuations in the Chinese coastal transport market.
