Platts proposes to amend Asian ethylene assessment cargo size specifications

Platts, part of S&P Global Energy, proposes to revise the cargo size specifications for its Asian ethylene assessments to reflect evolving trading norms, effective Jan. 4, 2027.

Based on market feedback, Platts understands that traded cargo sizes for Asian ethylene have increased in line with larger newbuild ships in recent years, and cargoes of up to 5,000 metric tons are now considered typical in the Asian markets.

To reflect these changes, Platts proposes to update the cargo size specifications for the assessments below:

Assessment Symbol Current Cargo Size Specification Proposed Cargo Size Specification
CFR Northeast Asia ethylene

AAOTM00 (Daily)

AAOUZ05 (Friday)

AAOTM05 (W eekly av erage )

FOB Korea ethylene

PHAJB00 (Weekly)

PHBGD03 (Monthly average)

2,500 mt – 3,500 mt 2,500 mt – 5,000 mt

The assessments are published on Platts Petrochemical Alert pages PCA238, PCA302, PCA 550, Olefinscan, Polymerscan and S&P Global Energy Core. They are also published in the Asia Petrochemicalscan.
