Platts launches daily M1, M2 butadiene FOB Rotterdam assessments

Platts, part of S&P Global Energy, has launched two new daily FOB Rotterdam butadiene spot price assessments Sept. 21.

These assessments complement the existing Platts FOB Rotterdam spot assessment for butadiene loading 3-30 days forward (PHAKG00) and mirror its terms and specifications.

The assessments reflect lots of a minimum 1,000 metric tons of butadiene, with a minimum purity of 99.5%.

The assessments reflect loading within the current (M1) and next (M2) month. The assessments' loading months roll to the next month three working days prior to the next month.

For example, in July 2026, the M1 assessment would reflect material loading any time in July, and M2 in August. On July 29, the M1 assessment would roll over to reflect butadiene loading in August, and M2 in September.

The assessment was first proposed on July 23 in a subscriber note available here, and was confirmed in a subsequent note on Aug. 21 here.

The assessment specifications are listed below:

The new assessments have a 1630 London time stamp and follow the UK publishing schedule.

Platts European butadiene price assessments can be found in Platts Petrochemical Alert pages PCA0439, PCA0461, PCA0321 and PCA0519, Platts Olefinscan report, Platts Polymerscan report and S&P Global Energy Core, accompanied by a weekly commentary and rationale published on Fridays.
