Platts proposes new CFR Central America PVC assessment, change in CFR WCSA basis ports, July 15

Platts, part of S&P Global Energy, is proposing to launch a new PVC suspension assessment for the Central American market and to refine the basis locations reflected in its CFR West Coast of South America PVC assessment, effective July 15, 2026.

New CFR Central America PVC assessment:

Platts is proposing this new assessment to bring additional price transparency in this region. The proposed assessment would reflect the K65 grade, while other comparable grades, such as K66 and K67, may be normalized to this standard. The basis location would be Santo Tomás de Castilla and Puerto Barrios ports.

Other information received outside the standard specifications may be considered for assessment purposes, subject to normalization.

Full details of the proposed assessment:

Updating CFR WCSA basis locations:

Platts is proposing to remove Cartagena, Colombia, as a basis port for its CFR West Coast South America (WCSA) PVC assessment (AASVH00).

Currently, the assessment reflects material delivered to Chile (Valparaiso, San Antonio), Colombia (Buenaventura, Cartagena), Ecuador (Guayaquil) and Peru (Callao).

Based on market feedback, Platts understands that Cartagena is not considered a par port, as US export cargoes to this location do not typically require transit through the Panama Canal.

The assessment would continue to be published on Wednesdays at 1:30 pm US Central Time, in line with the Brazil publishing calendar.

The CFR WCSA assessment is published in Polymerscan and Polymerscan Latin American Edition, on fixed pages PCA0245, PCA0246, PCA0818, on S&P Global Energy Core and in the Platts Price Point Database.
