Platts refines four Americas Sulfuric Acid price assessments July 1
Platts, part of S&P Global Commodity Insights, has refined the specifications of four Americas Sulfuric Acid price assessments, effective July 1.
Based on market analysis and feedback, the changes will provide a more detailed and up-to-date coverage of the specifications, such as quantity, timing and discharge ports, for the assessments to better reflect the sulfuric acid spot market activity dynamics in the Americas region.
The changes are summarized as follows:
The quantity specification for each of the assessments refined from "minimum 6,000 mt" to a basis of 10,000-20,000 mt, with price information relating to other volumes normalized to this point where necessary.
The location specification of each of these assessments has been refined or clarified to bring more transparency to the characteristics of each of these price assessments. In addition, the timing specification for each of these assessments has also been refined to better reflect the market dynamics of each location.
The weekly Sulfuric Acid price assessments are now published as a single "close" value with a 1630 São Paulo timestamp, following the São Paulo publishing calendar.
