Iron ore and steel futures in China fell again on Wednesday, while coking coal and coke also slumped after several days' of surging. The pullback was concentrated on steel and steelmaking futures. 

Iron ore dropped by its 6 percent downside limit for a second day, before closing 5.4 percent lower. Coking coal and coke also fell by the 6 percent maximum. Coke slightly trimmed losses to end down 4.9 percent. At close, rebar fell 3.7 percent and hot rolled dropped 4.6 percent.

China's major future exchanges have recently issued a series of curbing measures to cool the market, with transaction fees for coking coal and coke increased by 6 times. Analysts say the curbs seemed to be having the desired effect.
