Platts to implement changes to its suite of sulfuric acid Asia assessments June 25

Platts, part of S&P Global Commodity Insights, will implement changes to its suite of sulfuric acid Asia assessments, effective June 25.

This decision follows a proposal note (opens in a new tab)published April 9 and will add further granularity to Platts sulfuric acid coverage in Asia.

The changes are summarized below, followed by detailed explanations.

1. Launch of FOB South China and FOB China River sulfuric acid assessments.
2. Change in methodology for FOB China, sulfuric acid weekly range assessment (FSACA04)
3. Launch of FOB Japan and FOB South Korea sulfuric acid assessments.
4. Change in methodology for FOB Japan and South Korea (spot), weekly range assessment (FSAJB04)
5. Change in methodology for CFR India, sulfuric acid weekly range assessment (FSAIA04)

Launch of FOB South China and FOB China River sulfuric acid assessments

Platts will launch two weekly single-number sulfuric acid assessments, FOB South China and FOB China River, effective June 25.

Detailed specifications for the assessments are as follows:

Information regarding different location, cargo size and timing may be considered and normalized, where necessary, to align with the standard specifications listed above.

Change in methodology for FOB China, sulfuric acid weekly range assessment (FSACA04)

Platts will also change the methodology for its existing FOB China, sulfuric acid weekly range assessment, effective 25 June 2025. The assessment would reflect the FOB China, sulfuric acid price, with the range derived from the two new assessments outlined above rather than being assessed in its own right. No other market information will be taken into account.

For example, if FOB South China, sulfuric acid was assessed at $55/mt and FOB China River, sulfuric acid at $60/mt on a given date, then FOB China, sulfuric acid will be calculated as a range of $55-$60/mt.

Platts will also adjust the specifications for FSACA04 to align with those of the new assessments above.

Launch of FOB Japan and FOB South Korea sulfuric acid assessments

Platts will launch two weekly single-number sulfuric acid assessments, FOB Japan and FOB South Korea, effective June 25.

Detailed specifications for the assessments are as follows:

Information regarding different location, cargo size and timing may be considered and normalized, where necessary, to align with the standard specifications listed above.

Change in methodology for FOB Japan and South Korea (spot), weekly range assessment (FSAJB04)

Platts will also change the methodology for its existing FOB Japan and South Korea, sulfuric acid weekly range assessment, effective June 25. The assessment would reflect the FOB Japan & South Korea, sulfuric acid price, with the range derived from the two new assessments outlined above rather than being assessed in its own right. No other market information will be taken into account.

For example, if FOB South Korea, sulfuric acid was assessed at $45/mt and FOB Japan, sulfuric acid at $50/mt on a given date, then FOB Japan & South Korea, sulfuric acid will be calculated as a range of $45-$50/mt.

Platts will also adjust the specifications for FSAJB04 to align with those of the new assessments above.

Change in methodology for CFR India, sulfuric acid weekly range assessment (FSAIA04)

Platts will change the methodology for its existing CFR India, sulfuric acid weekly range assessment, effective June 25.

Platts will change the assessment name and location basis to CFR East Coast India. Following this change, the assessment will reflect a price basis CFR East coast India.

The new specifications will be as follows:

Information regarding different location, cargo size and timing may be considered and normalized, where necessary, to align with the standard specifications listed above.

All above assessments will appear in the sulphuric acid market report, Platts Connect, S&P Connect and the Platts price database.
