Platts to exclude taxes from Brazilian technical corn oil assessment Dec. 1

Platts, part of S&P Global Energy, will update its technical corn oil (TCO) ex-works Mato Grosso price assessment to exclude federal PIS/Cofins taxes, effective Dec. 1, 2026.

The assessment will then reflect prices excluding PIS/Cofins taxes, based on a combined tax rate of 9.25%.

The decision follows market feedback and reflects the growing prevalence of TCO trading conducted on a tax-exclusive basis. The change will provide a consistent reference for underlying market prices, allowing market participants to account for their applicable tax treatment. It will also better reflect export-oriented trade flows originating in Mato Grosso.

Bids, offers, and trades reported excluding PIS/Cofins taxes will then be considered without further tax adjustment. Platts will normalize bids, offers, trades and price indications reported inclusive of PIS/Cofins taxes to a tax-exclusive basis by removing the applicable tax component.

The proposal will affect the following assessments:

• TCO EXW Mato Grosso BRL/mt – Daily (TEMGA00)
• TCO EXW Mato Grosso BRL/mt – Weekly Avg (TEMGA04)
• TCO EXW Mato Grosso BRL/mt – Monthly avg (TEMGA03)
• TCO EXW Mato Grosso $/mt – Daily (TEMGB00)
• TCO EXW Mato Grosso $/mt – Weekly Avg (TEMGB04)
• TCO EXW Mato Grosso $/mt – Monthly avg (TEMGB03)

The assessments will continue to reflect a timestamp of 17:30 São Paulo.

This change was initially proposed Oct. 26 in a subscriber note available here.
