Overview

• Resolution 377/2025, published in the Boletín Oficial, sets a minimum acquisition price of $1,436,861 per tonne for biodiesel used in mandatory gasoil blending during September.
• The measure, signed by Energy Secretary María Carmen Tettamanti, supersedes Resolution 369/2025 issued earlier this month.
• The resolution establishes a maximum payment term of seven calendar days from the invoice date for biodiesel purchases.
• The Secretaría de Energía cites Law 27.640 and a technical report from the Subsecretaría de Combustibles Líquidos as the basis for the new reference price.
• The update constitutes a second price change for biodiesel in September, and biodiesel costs are one factor in overall diesel pricing.
