The EU–Mercosur agreement and Argentina: what exporters and importers get in 2026.

The interim trade agreement has applied since 1 May 2026. Here is what it gives Argentine exporters in Europe, how slowly Argentina opens to European cars and machinery, what happens to export duties, the origin paperwork that decides everything, and the angle from Paraguay.

The deal is live, and Argentina is in it.

After 25 years of negotiation, the trade part of the EU–Mercosur agreement has applied provisionally since 1 May 2026. It is the Acuerdo Interino de Comercio (the interim trade agreement), signed in Asunción on 17 January 2026 alongside the wider partnership agreement. The interim text covers trade only, does not need ratification by the 27 EU national parliaments, and will be replaced by the partnership agreement once that is fully ratified.

For business in Argentina the effects are concrete already. Argentine honey has entered the EU at 0% instead of 17.3% since May; Patagonian shrimp and hake go in duty-free; the Hilton beef quota pays 0% instead of 20%. In the other direction, Argentina has started a long schedule of cuts on European cars, machinery, chemicals and wine, and has committed to phase out most export duties on goods sold to Europe. This guide covers both directions, the origin paperwork that decides whether you get any of it, quotas, and what the agreement means if your company sits in Paraguay.

Law and practice: Law 27,800 (Boletín Oficial, 26 February 2026), promulgated by Decree 111/2026; OJ L, 2026/184 and OJ L, 2026/868; bilateral safeguard rules in Regulation (EU) 2026/687.

Which instrument, and who applies it.

Argentina and Uruguay were the first to ratify, on the same day. Argentina’s Congreso handled the bill in extraordinary sessions and the executive published the law the afternoon the Senate voted. Once all four Mercosur states had notified completion, the EU applied the agreement provisionally with each of them from the same date, so there is no staggered start: Argentina, Brazil, Uruguay and Paraguay all count year 0 as 1 May to 31 December 2026. Year 1 starts on 1 January 2027, and quota volumes are set per calendar year.

The EU side is not finished. The European Parliament has not given its final consent and asked the EU Court of Justice for an opinion; the Commission went ahead with provisional application on the basis of the Council’s January 2026 decision. A negative opinion would be a political problem, but provisional application gives the tariff preferences full legal effect today.

Beef, honey, fish, wine and fruit.

The EU removes duties on 92% of Mercosur’s exports and gives quota access for another 7.5%. Most of the 92% was free on day one; the rest falls over 4, 7 or 10 years. Sensitive farm goods enter through cupos (tariff-rate quotas, TRQs), shared by the four Mercosur states and phased in over six equal stages, from year 0 to year 5.

Two details matter for the table. First, year 0 is a short year: quotas are prorated to May–December, so the beef quota opened at 6,050 t fresh and 4,950 t frozen for the whole bloc, and the honey quota at 5,000 t, split into quarterly sub-quotas. The first honey sub-quota was used up within weeks, mostly by Argentine exporters. Second, Mercosur has not yet agreed how each quota is split between its members. Until it does, many quotas run on first come, first served, and Uruguay and Paraguay have formally complained about the method.

For fruit, read the EU’s staging category, not the headline. Lines under the entry-price system (categories 0/EP, 7/EP and 10/EP) lose their ad valorem duty, but the specific duty still applies when the import price is below the EU reference price. A cheap lemon shipment can still pay.

Law and practice: EU quota volumes and staging: Annex 2-A, Appendix 2-A-1 of the interim agreement; quota administration in Regulations (EU) 2026/888 (licences) and 2026/996 (first come, first served); Argentine summary in the Cancillería implementation guideline.

Slow on cars, faster on parts and inputs.

Mercosur’s schedule is much slower than the EU’s. It removes duties on 91% of EU goods, but only about 15% immediately; the rest falls over 4, 8, 10 and 15 years, and roughly 9% is excluded. Cuts happen in equal annual steps, so a category-10 product loses a tenth of its base duty each year.

For Argentina the agreement stacks on top of its own unilateral cuts. Under Decree 513/2025, many capital goods already fell to 12.6%, and the 2025 cuts on clothing and phones are explained in our Argentina customs guide. The agreement locks the European preference in and takes it to zero. What it does not touch is the rest of the border bill: VAT, the VAT, income tax and Ingresos Brutos (provincial turnover tax) prepayments still apply to EU goods. The 3% tasa de estadística (statistics fee) stays until 1 May 2029, when it ends for EU goods together with the consular formality.

For cars, the vehicle must also be European: non-EU materials may not exceed 45% of the ex-works price. A non-European brand assembling in Europe has to check its parts content line by line before counting on the quota.

Law and practice: Mercosur schedule: Annex 2-A, Appendix 2-A-2. Car quota administered first come, first served; importers apply in Argentina with the agreement code “MERCOSUR-UE” on the customs declaration.

Retenciones on goods sold to Europe.

Argentina’s derechos de exportación, known as retenciones, are the agreement’s most unusual chapter. The EU rarely gets export-duty commitments, and Argentina, Uruguay and Paraguay accepted full elimination on most goods, while Brazil only accepted caps.

In practice the caps sit above current policy. Decree 423/2026 already takes soybean duty from 24% to 21% in December 2027 and 15% in December 2028, below the 18% cap for 2031. The value of the chapter is that it binds: a future government cannot raise retenciones on EU-bound goods above the caps without breaching a treaty. For investors in agro-processing, mining and petrochemicals, that is the point.

Law and practice: Annex 2-B of the interim agreement; Decree 423/2026 (Boletín Oficial, 3 June 2026).

No origin, no preference.

Preferences apply only to goods that originate under the agreement’s product-specific rules (Annex 3-B). Shipping from Argentina is not enough: a product must be wholly obtained or sufficiently processed in Mercosur, with a general tolerance of 10% of the ex-works price for non-originating materials. Materials from the EU count as originating (bilateral cumulation), and goods must travel without manipulation in third countries.

Argentine exports. There is no separate origin registry to join. Under Disposición SSCE 1/2026 the exporter generates an origin declaration on the TAD platform (Trámites a Distancia, the government’s online filing system), signed digitally, with its CUIT (tax ID), the importer’s details, the HS code at six digits, the invoice number and a sworn statement of Mercosur preferential origin. The origin stated is “MERCOSUR”, not “Argentina”. The declaration is valid for 12 months and goes to the EU buyer with the invoice. The authority does not check it in advance: the exporter carries the risk, must keep the evidence for at least three years, and faces suspension for up to 18 months, or disqualification for up to five years for repeat or fraudulent declarations. The EU can request verification within two years and Argentina has ten months to answer; without an answer, the preference is denied.

Imports from the EU. European exporters self-certify through the EU’s REX system (Registered Exporter). The statement on origin in Argentina must be in Spanish, Portuguese or English, carry the exporter’s REX number and state the origin as “Unión Europea”; it is valid for 12 months. Exporters not registered in REX can only self-certify consignments up to €6,000. Importers can claim the preference up to two years after import.

Certificates for exporters, licences for importers.

Argentina runs its side of the quotas under Resolución SAGyP 50/2026 of the Secretariat of Agriculture, in force since 1 May 2026. Beef is handled separately.

Names you can no longer use, tenders you can now bid for.

The EU protects 220 Mercosur indicaciones geográficas (geographical indications), about 100 of them Argentine and mostly wine regions: Mendoza, Luján de Cuyo, Valle de Uco, Cafayate, Patagonia and others, plus Yerba Mate Argentina and Cordero Patagónico. Mercosur protects about 350 European names. Argentine producers who used European names before the cut-off can keep them under the prior-user rules for listed terms, but a new brand cannot launch a local “Parmesan” or “Champagne”. A wine annex settles labelling, oenological practices and traditional terms such as “Reserva”.

Mercosur opens public procurement to EU bidders for the first time, at central-government level and above thresholds, with notices published at a national single point. EU tenders open on the same terms for Argentine suppliers. In practice it helps European engineering and equipment groups more than Argentine SMEs, and Paraguay kept more room to protect its own purchasing.

What changes for a Paraguay-based company.

Paraguay applies the agreement from the same date, 1 May 2026, after ratifying it on 30 March. It received special treatment as a small landlocked economy: longer phase-outs on its own imports, an exclusive sugar quota of 10,000 t, a share of 750 cars in the 50,000-unit quota and a few more flexible origin rules. For a group with a company in Paraguay, four points matter.

• ✓

  Mercosur origin is shared

  Because origin is “MERCOSUR”, Paraguayan inputs processed in Argentina count as originating, and the reverse. A Paraguayan maquila supplying an Argentine exporter to the EU does not break the chain.

• ✓

  Paraguay’s Mercosur flexibility does not travel

  The 60% non-Mercosur allowance Paraguay enjoys inside Mercosur until 2038 is not the EU test. Exports to Europe must meet the EU agreement’s product rules.

• ✓

  Import where you sell

  EU goods should enter the country of consumption directly. Preference is claimed by each importing state; landing in Paraguay and trucking to Argentina does not create Mercosur origin.

• ✓

  Quota competition

  Paraguayan and Argentine exporters draw on the same first-come quotas; the country split still being negotiated will decide who keeps the volume.
