Overview

• Resolutions 385/2025 and 386/2025 published on October 6 set the biodiesel minimum at ARS 1,508,704 per ton and bioethanol at ARS 891,286 per liter for cane and ARS 816,887 per liter for corn.
• The rules formalize maximum payment deadlines of seven days from invoicing for biodiesel purchases and up to 30 days for bioethanol.
• The new levels replace September references and reflect month‑over‑month increases of 6.71% for biodiesel and 4% for both bioethanol pathways.
• The updates operate within Law 27.640’s biofuels regime and rely on emergency powers under Decree 70/2023 and Law 27.742 to address cost‑price gaps.
• The floors apply to mandated blends with diesel and gasoline, a factor that can influence refiners’ costs, after producers flagged below‑cost sales and cash‑flow pressures in recent months.
