NOTICE: Mysteel iron ore data surveys expand samples

Starting May 6 2020, the iron ore department will enlarge samples for a series of market surveys so as to present the market with a more coherent data service.

The changes are based on market feedback in the few years as well as the evolution in China’s steel industry landscape since 2016 when excess steel capacities have been trimmed and steel product structure and technology have been upgraded via new projects via capacity swap plans.

Details regarding the series of surveys with larger samples:

i): The 19 newly-added Chinese ports in the “iron ore arrivals” are Dandong Port, Jinzhou Port, Nanjing Port, Taizhou Port, Weifang Port, Laizhou Port, Shekou Port, Gaolan Port, Quanzhou Port, Qinzhou Port, Guangzhou Port, Mawei Port, Mawan Port, Zhenjiang Port, Fuzhou Port, Changzhou Port, Rugao Port, Meijin Port, Yangzhou Port. Definition of “arrival”: all the iron ore carriers that approach Chinese terminals at the speed of 0.3 knot according to the satellite tracking.

ii): The imported sintering iron ore inventories at 64 Chinese steel mills will be enlarged to 247 steel mills to match the other existing surveys on these mills’ blast furnace operational and capacity utilization rates.

Besides, the inventories will be including mills’ imported cargoes on the water, at the ports and at their plants instead of only the volume at the plants. 

As for the iron ore, all fines, concentrates, lumps, and pellets will be included from the originally just the fines.

“Stocks-to-consumption ratio” in the release is calculated via the calculation of total inventories/daily consumption.

iii): Imported iron ore inventories at the 45 Chinese ports with detailed breakdowns available in the second release of the week.

iv): A total of 768 blast furnaces in 247 steel mills or 970 million tonnes/year in hot metal capacity will be included, which represents 94.8% of the country’s total for 2019 against the 975 million t/y and 95% for 2017. Obsolete and idled blast furnaces have been replaced with the newly-commissioned or upgraded furnaces.

The data has been backdated to January 1 2020.

The survey on a smaller sample of 163 steel mills will cease updating on January 1 2021.
