Two hours south of Mar del Plata, in the flat, windy farmland of Buenos Aires Province, McCain Foods runs a complex that does something no other facility in the Southern Hemisphere does at this scale: it turns Argentine potatoes into frozen French fries on contract for restaurant chains across South America. The Balcarce plant has been there since the late 1990s. What's new is everyone else who is moving in around it.
Lamb Weston has been quietly expanding its Argentine footprint. USDA Foreign Agricultural Service reporting confirms the company is investing in additional capacity specifically to serve South American markets. McCain itself has been adding lines. Local processors and joint ventures are building out alongside the multinationals. And the destination, increasingly, is one place: Brazil.
For the first time in the modern era, Belgium's effective monopoly on global frozen fry exports — 26.8% of world trade, $4.6 billion in 2024 — is meeting a serious geographic challenger. Argentina isn't going to dethrone Belgium. But it doesn't need to. It just needs to lock down South America.
Why Argentina, why now
Argentina has been growing potatoes for fries for decades — the country's domestic processing industry, organised around chains like Mostaza, Burger King, and Argentine McDonald's, has been a steady mid-tier business. What's new is the scale of the export ambition.
Three structural advantages converge here. First, land. The Pampas — Buenos Aires Province, southern Santa Fe, parts of Córdoba — contain some of the cheapest, flattest, most irrigated potato land on Earth. Argentine producers can grow Russet Burbank-equivalent processing varieties for substantially lower input costs than Belgian, Dutch, or Idahoan competitors. Second, counter-seasonal supply. Argentine potatoes harvest in March–April, exactly when Northern Hemisphere stocks are most depleted — a structural arbitrage opportunity for global frozen-fry trade. Third, and most importantly: Mercosur.
The Brazil card
Mercosur — the South American common market that includes Argentina, Brazil, Uruguay, Paraguay, and (associate) Bolivia and Chile — means Argentine frozen potato products move into Brazil tariff-free. Belgian, Dutch, Canadian, and US fries face Brazilian import duties of roughly 14–18% (depending on the precise HS code and trade circumstance). For a high-volume, low-margin commodity like frozen fries, that's an enormous structural advantage.
The Brazilian market is the prize. Brazil's frozen potato imports totalled approximately 200,000 tonnes worth more than $250 million in 2023, according to the SECEX/MDIC trade database — and that figure has been growing roughly 10–15% per year as Brazilian QSR consumption deepens. Argentina supplies an estimated 40–45% of those imports already, with capacity to take more. The remaining share goes to Belgium, the Netherlands, and Canada — all of whom pay the tariff.
The math for global processors is hard to argue with. McCain's global operations process more than 4.5 million tonnes of raw potatoes per year, producing roughly 2 million tonnes of finished frozen products. Even a 1% shift of that volume into Argentina-for-Brazil redirects 20,000+ tonnes annually — with structurally better margins than competing through tariff walls.
Belgium's response (and why it's not panicked)
Belgium isn't sitting still. Clarebout has just opened a 220,000-tonne facility in Bourbourg near Dunkirk. Agristo has €350 million in new French capacity coming online. Lutosa (now part of McCain) is modernising. Aviko has built a new Flemish factory. The North-Sea-coast potato belt is doubling down on Belgian dominance, particularly for European, Middle Eastern, and African markets where Mercosur tariff arbitrage doesn't apply.
What Belgium is conceding is South America. The cost-to-serve from Antwerp to São Paulo, plus 14–18% tariff, simply can't compete with from-Balcarce-to-São-Paulo at zero tariff. Belgian processors have been clear with their analysts: South America is structurally an Argentine market now. The Belgian industry's growth engines are Africa (Egypt is rising as competition there too), the Middle East (Saudi/UAE driven), and Asia (where Belgian fries still command premium positioning).
The other South American players
Argentina isn't the only Southern Hemisphere processor with ambitions. Peru is a fresh-potato origin nation but still imports finished frozen fries; Chilean and Colombian production is rising; Mexico has a long-established processing base mostly serving the domestic market. But none has Argentina's combination of cheap land, irrigation infrastructure, processor presence, and Mercosur tariff position.
What's interesting is the parallel rise of other emerging frozen-fry exporters — the same dynamic playing out in different geographies. Egypt has tripled its fry exports in five years to ~220,000 tonnes annually, serving Brazil, Saudi Arabia, the Gulf, and even the United States. India's frozen fry exports have grown 265% since 2020 to nearly 270,000 tonnes. China became a net frozen-fry exporter in 2022. Each of these countries is doing for its region what Argentina is doing for South America: undercutting the Belgian/Dutch/American base on regional cost-to-serve. The global frozen-fry industry is no longer a North Atlantic monopoly.
What this means for the consumer (and the industry)
For the average eater of frozen fries, none of this is visible. The fries on a Brazilian plate increasingly come from Argentina; the fries on a Saudi or Egyptian plate increasingly come from Egypt; the fries in a Tianjin food court increasingly come from Chinese factories. The product looks the same. The economics underneath have changed completely.
For the industry, Argentina's bet matters because of what it confirms: the era of Belgian processing dominance is being structurally bracketed by regional alternatives. Belgium will remain the world's largest exporter for the foreseeable future — the installed capacity, the Northwest European potato belt, and the global brand are all genuine moats. But the share of global trade that Belgian factories will compete for is shrinking, region by region. Lamb Weston, Simplot, and McCain saw this coming. The pampas factories are the result.
