Platts to amend basis locations for its polyolefins CFR Mercosur assessments

Platts, part of S&P Global Commodity Insights, will narrow the basis location for its CFR Mercosur polyethylene (PE) and polypropylene (PP) assessments to Montevideo (Uruguay) and Buenos Aires (Argentina), effective Sept. 25, 2025.

Platts, in its current methodology, identifies Asunción (Paraguay) as a par port, alongside Montevideo and Buenos Aires.

However, market feedback indicates that the logistics and delivery costs to Asunción do not align with those of Montevideo and Buenos Aires, resulting in a consistent divergence of values between Asunción and other locations in the region.

The CFR Mercosur PE and PP assessments are published every Wednesday, and in accordance with the Brazil holiday publishing schedule, in Polymerscan (PO) and Latin American Polymerscan (POLA), as well as on Platts Connect and in the Platts Price Point database under the following codes:

Information received for other basis locations and under other incoterms, such as CPT and CIF, may also be considered, subject to normalization, as clarified here.

Platts previously proposed the change in a note published on Aug. 14, 2025, available here.
