Argentina's Secretaría de Comercio Interior (Secretariat of Internal Commerce) and the Comisión Nacional de Defensa de la Competencia (National Commission for the Defence of Competition. Alternatively. CNDC) have intensified enforcement activity under competition legislation over the past eighteen months. Investigations targeting cartel conduct, market dominance abuses, and unreported concentrations have increased sharply. Penalties issued in recent cycles reach into the hundreds of millions of Argentine pesos, with the CNDC signalling further escalation.
Argentina's competition authority is actively enforcing merger notification rules, cartel prohibitions, and market dominance restrictions under the country's competition legislation. International companies operating in Argentine markets – or completing transactions that affect those markets – face mandatory filing obligations and risk substantial penalties for non-compliance. Businesses with Argentine revenues or market positions above prescribed thresholds must assess their exposure immediately.
This alert explains which business categories are affected, what the threshold criteria are, and which immediate steps international companies should take to reduce enforcement risk.
What has changed and who is affected
Argentina's competition legislation, as amended and applied by the CNDC, establishes three principal areas of active enforcement. Each carries distinct obligations and penalty consequences for international businesses.
Merger notification. Transactions where the combined Argentine turnover of the parties exceeds prescribed thresholds trigger a mandatory pre-merger notification requirement. The CNDC has tightened its review of cross-border deals that produce effects in Argentine markets – even where neither party is incorporated in Argentina. Failures to notify, or to obtain clearance before closing, expose the transaction parties to fines and potential unwinding orders. The CNDC has issued public statements confirming that foreign-to-foreign transactions are not exempt if Argentine market effects are present.
Cartel conduct. Price-fixing, bid-rigging, market allocation, and output restrictions between competitors are prohibited under Argentine competition legislation. Enforcement has focused on sectors including food distribution, pharmaceuticals, construction materials, and logistics. The CNDC has used dawn raids – unannounced inspections – with increasing frequency. Companies found to have participated in a cartel face fines calculated as multiples of the value of the affected commerce, alongside reputational consequences and private civil actions from harmed parties.
Market dominance abuse. Companies holding a dominant position in an Argentine market – assessed by reference to market share, barriers to entry, and buyer dependency – face restrictions on pricing, supply refusals, and exclusionary contracting. The CNDC has opened proceedings against both domestic operators and subsidiaries of international groups. Exclusivity clauses, loyalty rebates, and below-cost pricing are subjects of active scrutiny.
Businesses most at risk include multinationals with Argentine subsidiaries or distribution networks, foreign companies supplying Argentine buyers under long-term contracts, and any party to a cross-border transaction with Argentine revenue dimensions. Companies in regulated sectors – energy, telecommunications, food, and healthcare – face heightened scrutiny given the CNDC's stated sector priorities.

Immediate action items for international companies
The window between an enforcement trigger and a formal CNDC investigation is often narrow. Companies that act before proceedings commence have considerably more options. including access to Argentina's programa de clemencia (leniency programme). This offers penalty reductions or immunity to the first party to disclose a cartel and cooperate with the CNDC. Once an investigation opens, leniency terms become less favourable and the risk of criminal referral increases.
International companies should address the following items without delay.
- Audit pending and recent transactions for Argentine turnover against merger notification thresholds. Any transaction closed without notification where thresholds were met should be assessed for retroactive filing risk.
- Review commercial agreements with Argentine competitors, distributors, and buyers for clauses that may qualify as cartel conduct or market dominance abuses under Argentine competition legislation. Exclusivity provisions, price parity obligations, and territorial restrictions deserve particular attention.
- Map your Argentine market position. If your group holds a significant or dominant share in any Argentine product or geographic market, document the commercial rationale for pricing, supply, and contracting decisions now – before any CNDC inquiry arrives.
- Prepare a dawn raid protocol. Designate who in your Argentine operation has authority to engage with CNDC inspectors, and ensure that no documents are destroyed or communications deleted when investigators arrive. Obstruction carries separate penalty exposure.
- Evaluate leniency eligibility. If there is any internal evidence of past or ongoing cartel participation, seek legal advice on whether a leniency application is appropriate before a competitor or the CNDC acts first.
