China's average daily crude steel output fell for the third straight 10-day period and declined 3.7 percent in the first 10 days of December, data from the China Iron & Steel Association showed on Tuesday.

The daily output stood at 2.013 million tonnes, falling from 2.091 million tonnes in the Nov. 21-30 period.

CISA estimated the country's total production based on its members, including more than 80 large steel mills that account for about 80 percent of China's total steel output.

CISA members produced 1.695 million tonnes of crude steel on an average daily basis during the same period, slipping 0.8 percent from the preceding period, data showed.
