Procedures & Methodology

TSI's clearly defined and transparent methodology is the backbone of its iron ore, steel, scrap and coking coal prices. TSI was the industry pioneer in compiling prices based on actual spot transaction data gathered directly from industry participants throughout the supply chain. TSI applies its methodology consistently in the compilation of all of its indices around the world, providing clients with the confidence they need that all its prices are directly comparable.

Over 550 companies ('Data Providers') have registered and been approved to submit their pricing information to TSI and, in exchange, they see their data represented in the respective index. This offers significant advantages over traditional 'telephone polling' approaches: it is fast, secure, verifiable and enables Data Providers all over the world to submit data at their convenience. More information can be found in the documents below.
