What changed and who it applies to
What changed
The Energy Secretariat repeals Resolution 241/17, which required exporters of crude oil, gasoline, diesel, propane and butane to first publish a sale offer for the product aimed at the entire authorized domestic trade chain (with no discriminatory conditions, allowing full or partial purchase) before they could export it. In its place it creates the 'Export Operations Registry', where the export notification, any objections raised, and the Free Export Certificate are filed, with the detailed procedure set out in Annex IF-2026-67983213-APN-SSH#MEC. verif · Jul 22, 2026 ↗

Our reading
This is the operational rule that the parent decree (1057/2024) called on us to watch for — and it confirms the thesis rather than contradicting it: instead of reintroducing a barrier, the Energy Secretariat removes the last remnant of intervention over crude and product exports (the prior offer to domestic buyers) and replaces it with a simple registry. One more step in the same direction: exporting hydrocarbons no longer depends on a discretionary procedure (R4 · opening and deregulation). thesis
