Following market feedback, Platts, part of S&P Global Commodity Insights, will update the location specification of its steel slab CFR Southeast Asia assessment from Cigading to Surabaya, Indonesia, effective Sept. 25, to better reflect changes to trade flows and spot market liquidity.
Concurrently, Platts will increase the assessment frequency from monthly to weekly on Thursdays and will introduce a monthly average of the weekly assessments.
Of the 1.18 million mt of slab Indonesia imported in 2024, 67% was delivered to Surabaya, followed by 17% to Cilegon and 16% to Jakarta, according to data from Indonesia's Central Statistics Agency (BPS).
The assessment affected and the updated specifications are listed in the table below:
| Assessment | Symbol (Monthly average) | Current location specification | Updated location specification effective Sept. 25 | Current publication frequency | Updated publication frequency effective Sept. 25 |
| Slab CFR Southeast Asia | SB01235 (SBOAM03) | Cigading, Indonesia | Surabaya, Indonesia | Monthly | Weekly (Thursdays) |
Platts will continue to consider market information for delivery to Cigading and other Southeast Asian locations, and may apply normalizations, including for freight rates, to Surabaya.
The first monthly average will update at the start of November and will reflect the average of weekly assessments published in October.
Platts initially proposed the location specification and assessment frequency change on Aug. 14 in a subscriber note available at: https://www.spglobal.com/commodity-insights/en/pricing-benchmarks/our-methodology/subscriber-notes/081425-platts-proposes-to-update-location-specification-increase-frequency-of-steel-slab-cfr-southeast-asia-assessment
Full details of the Slab CFR Southeast Asia specifications can be found here: https://www.spglobal.com/commodityinsights/PlattsContent/_assets/_files/en/our-methodology/methodology-specifications/steel-ferrous-methodology.pdf
Platts Slab CFR Southeast Asia assessments are published on fixed pages STL/PMA 1370 of the real-time Platts Steel Alert and Platts Metals Alert, in Steel Price Report and in the Platts price database.
