Platts proposes to implement changes to its suite of Sulfuric Acid Asia assessments June 25

Platts proposes to implement changes to its suite of Sulfuric Acid Asia assessments, effective 25 June, 2025.

The proposed 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 Sulfuric Acid FOB South China and Sulfuric Acid FOB China River assessments

Platts proposes to launch two sulfuric acid assessments, FOB South China and FOB China River, effective 25 June, 2025. These proposed weekly single-number assessments would add further granularity to Platts sulfuric acid coverage in the China region.

Detailed specifications for the proposed 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 Sulfuric Acid FOB China weekly range assessment (FASCD04)

Simultaneously, Platts proposes to 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 would be calculated as a range of $55-$60/mt.

Launch of Sulfuric Acid FOB Japan and Sulfuric Acid FOB South Korea assessments.

Platts proposes to launch two sulfuric acid assessments, FOB Japan and FOB South Korea effective 25 June, 2025 . These proposed weekly single-number assessments would add further granularity to Platts sulfuric acid coverage in the North Asia region.

Detailed specifications for the proposed 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 Sulfuric Acid FOB Japan and South Korea (spot), weekly range assessment (FSAJB04)

Simultaneously, Platts proposes to change the methodology for its existing Sulfuric Acid FOB Japan and South Korea, sulfuric acid weekly range assessment, effective 25 June. The assessment would reflect the Sulfuric Acid FOB Japan & South Korea 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 would be calculated as a range of $45-$50/mt.

Change in methodology for Sulfuric Acid CFR India weekly range assessment (FSAIA04)

Platts proposes to change the methodology for its existing Sulfuric Acid CFR India weekly range assessment, effective 25 June. Platts proposes to change the assessment name and basis to CFR East Coast India. Following this change, the assessment would reflect a CFR East coast India basis.

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