1. Carbon Steel Index is compiled from a basket of finished steel prices with various weightages. The compilation of the index has taken into consideration both the product’s characteristics and the regional consumption models in China.
Among the components are long steel and flat steel as well as seven core consuming cities to represent the regions including East China (Shanghai), South China (Guangzhou), Central China (Wuhan), North China (Beijing), Southwest China (Chongqing), Northeast China (Shenyang) and Northwest China (Xi'an).
2. Carbon Steel Index is based on the mainstream transaction prices in the seven cities.
3. “Long Steel” category comprises rebar (20mm dia, HRB335Mpa) and high-speed wire rod (6.5mm dia), and “Flat Steel” is composed of four steel products, which are steel plate (Q235, 20mm), HRC (SS400, 3.0mm), CRC (SPCC, 1.0mm) and HDG (SPCC, 1.0mm).
4. “Integrated Mill Steel” refers to rebar, wire rod, plate, and hot-rolled plate, coil, and strip produced by the integrated mills including both blast-furnace and electric-arc-furnace plants instead of re-rollers.
5. July 2000 is defined as the benchmark for the index value at 100. The weekly indices are with historical data running back to July 2000, while monthly indices are as far back as January 1997.
6. Transaction prices for the Carbon Steel Index calculation are sourced from two origins with the data after July 2000 based on Mysteel's series of daily price assessments, and those running over January 1997-June 2000 are from reliable historical prices that were released by third parties prior to the incorporation of Mysteel.
