Platts to launch FOB Kalimantan 5,800 kcal/kg GAR thermal coal assessment

Platts, part of S&P Global Commodity Insights, will launch a daily price assessment for FOB Kalimantan 5,800 kcal/kg GAR thermal coal, effective Dec. 1.

Market survey and feedback suggest that the majority of the mines in Indonesia produce 5,800 kcal/kg GAR grade coal, and volume-wise, 5,900 kcal/kg GAR has become less prominent over the years.

To supplement the existing suite of FOB Kalimantan coal assessments, the new assessment, in $/metric ton, will reflect coal with a calorific value of 5,800 kcal/kg GAR, or 5,500 kcal/kg NAR, having a typical sulfur value of 0.8%, within a range of 0.8%-1%, a typical ash value of 8%, within a range of 8%-10%, and a total moisture content of 15%, within a range of 15%-18%.

Other details of the specifications:

CV: 5,800 kcal/kg GAR

CV Range: 5,600-5,800 kcal/kg GAR

Vessel Size: 75,000 mt

Incoterms: FOB Kalimantan, Indonesia

Delivery Period: 15-60 days forward

For sulfur and ash, respectively, Platts has launched daily price differential assessments for every 0.1% and 1% above the typical levels and up to the maximum of the ranges, effective Oct. 30.

All market information reported to Platts may be considered and published in real time, including firm bids and offers, trades and indicative values, as well as any other data deemed relevant to the assessment process.

Pricing information with terms, locations and specifications different from the above standard may be considered for assessment purposes, subject to normalization. Platts will consider information from adjacent markets in its assessments.

The new assessments will be published on a daily basis, following the Singapore publication schedule, and will be based on the latest information sourced from the market up to the close of the Platts Market on Close assessment process at 17:30 Singapore time.

The new daily assessments will be published in Platts Coal Trader International, fixed pages, GC0420.

This decision follows a proposal published Oct. 13.
