What changed and who it applies to
What changed
Decreto 563/2025 sets at 0% the Export Duty (D.E.) rate for the goods covered by the NCM tariff positions detailed in its Annex (IF-2025-80536077-APN-SM#MEC), which covers non-metallic mining, metalliferous mining, construction rocks, fuels and precious/semi-precious stones (lime, granite, borates, dolomite, bentonite, copper, zinc, lead, etc.). The official communication and CAEM quantify the scope at 231 positions (41 construction minerals, 54 non-metallic, 133 metalliferous); that count comes from the official communication/press, not from the Annex audited position by position (the Annex is published only in the web edition of the Official Gazette). Lithium and silver are NOT included in the Annex; according to the official communication, they keep their pre-existing rate of 4.5% (the decree does not name that rate). Art. 2 repeals Decreto 308/2022, which had created the Optional Copper Export Registry (with no registered beneficiaries). verif Aug 6, 2025 ↗

Who it applies to
Mining-sector exporters whose products appear in the decree's Annex, a list of tariff positions covering non-metallic minerals and rocks (among them lime, granite, borates, dolomite and bentonite), copper, zinc and lead ores and metals, gold ore and gold powder, hard coal and precious stones verif. Mining accounts on average for 80% of the export basket of Jujuy, Santa Cruz, San Juan and Catamarca, according to the decree's recitals verif. The list does not include the positions for lithium carbonate and hydroxide or for silver and its ore, so those products do not get the zero rate verif; this decree does not say what rate they pay. verif Aug 6, 2025 ↗

Our reading
The Government takes export duties to 0% on most mining products: less tax burden, more margin for operators and supplier SMEs and a direct incentive to export and produce (R5, tax cut; R4, deregulation). It is consistent with the course of opening and simplification. What is worth following: lithium and silver were left out (according to the official communication, they stay at 4.5%), and being a delegated decree it goes through the Bicameral Committee — the fine scope depends on the NCM Annex, which we have not yet audited position by position. thesis

Where it lands, province by province5
Neuquén In Neuquén the 0% mining export duty does not improve an existing margin: provincial mining is pre-productive and CORMINE has only just become a corporation in order to partner with private players on lithium and copper. So it arrives as a condition set before the investment decision. And the province is already writing on the other side: its own mining royalty regime, 3% if processed outside and 2% if within. favorable better export netback thesis
Río Negro Calcatreu made the first gold and silver export in Río Negro's history: doré of ~70% gold and 30% silver. Gold goes to 0% and silver keeps its pre-existing 4.5%, so the relief is partial and depends on which tariff line the doré is declared under. Sierra Grande's iron, which falls in the same metals family, does not add to this today: metal ores are not among the categories INDEC lists for Río Negro's exports in 2025 or in the first half of 2026, and we found no shipment from the mine after 2017 unconf. favorable better export netback thesis
Salta Salta's 2025 mining basket is 59.1% gold, 26.7% lithium, 12.8% borates and 0.8% copper. The decree's annex names borates and takes them to 0%, but leaves out lithium and silver, which stay at 4.5%: the line growing at 222% year-on-year and Diablillos' by-product are precisely the two that do not fall. Here the cut in export duties relieves the small and skips what is being built. mixed better export netback thesis
Catamarca Decreto 563/2025 takes mining export duties to 0% but leaves lithium and silver out of the Annex; according to the official communication they stay at 4.5%. Catamarca has the country's highest mining-to-exports ratio (95.1% between January and August 2026) and its entire producing portfolio is brine lithium — Fénix, Sal de Vida, Tres Quebradas, Hombre Muerto Oeste: it does not capture the cut. Agua Rica/MARA copper does, but it is halted by an environmental permit. The netback that moves expansions did not move here. mixed better export netback thesis
San Juan From January to August 2026, 87.6 % of what San Juan exported was mining, and nearly all of it was gold verif. Of gold, the decree's Annex only lists the ore (2616.90) and gold powder (7108.11), not the other unwrought forms (7108.12), where doré is usually classified verif. If the doré from Veladero and Gualcamayo is declared under that position, it does not get the zero rate: this has to be confirmed before assuming the cut lifts their netback thesis. For the copper still to come, the 0% enters the investment-decision calculation thesis. Silver, which ships in the same doré, is left out of the Annex and according to the official communication stays at 4.5% prob. favorable better export netback thesis
