Bioceanic Corridor
and its logistical impact.
The corridor linking the Atlantic with the Pacific across the Andes. What it is, why Mendoza is its central node, required documentation, and everything you need to know to plan Argentina–Chile international cargo.
From Buenos Aires
to the Pacific by truck.
The Central Bioceanic Corridor is the road axis connecting Atlantic ports (Buenos Aires, Rosario) with Pacific ports (Valparaíso, San Antonio) through the Andes. The main stretch for Argentina passes through Mendoza and the Cristo Redentor / Los Libertadores International Pass, the highest-traffic cargo crossing between both countries.
For Argentine foreign trade — especially from the central-western provinces — this corridor represents the most competitive route to Pacific markets: Asia, Australia, the US west coast, and southern Latin America. For cargo originating or destined in Mendoza, Cuyo, San Juan, or Neuquén, the Buenos Aires alternative involves a detour of 500 to 1,200 additional km.
Rutas del Sur has operated on this corridor for over 40 years. We know its variables, its seasons, its checkpoints, and how to plan to minimize the unexpected.
Corridor advantages
for exporters and importers.
Lower cost per kilometer than Atlantic ports
For cargo originating in central-western Argentina (Mendoza, San Juan, Neuquén, Cuyo), the corridor through Mendoza to Chilean Pacific ports involves 400 to 900 fewer kilometers than the Buenos Aires or Rosario alternative. In heavy cargo logistics, every avoided kilometer is a direct cost saving.
Direct access to the Pacific and Asian markets
The ports of Valparaíso and San Antonio connect directly to Asia-Pacific markets — the main destination for Argentine mining and agro-industrial exports. Maritime transit time from the Pacific to Shanghai or Tokyo is significantly shorter than from the Atlantic.
World-class Chilean port infrastructure
The ports of Valparaíso, San Antonio, and Coquimbo have infrastructure for bulk, container, and general cargo handling. The Port of San Antonio is one of the largest in South America by container volume and operates at efficiency standards comparable to the best ports on the continent.
What documentation
you need to cross.
International Cargo Manifest / Customs Transit Declaration. Main document for cross-border cargo between Argentina and Chile. Filed with the origin customs office.
Required for plant-origin cargo, agricultural products, timber, and derivatives. Issued by SENASA (Argentina) or SAG (Chile) depending on the country of origin.
Cargo detail with description, weight, volume, and FOB value. Essential document for customs inspection in both countries.
For chemicals, flammables, explosives, or other risk-category items. Requires carrier and vehicle permits, plus specific documentation per substance type.
Required to access tariff preferences under the ACE 35 Agreement between Argentina and Chile. Obtainable from Chambers of Commerce or AFIP.
For vehicles exceeding 38 total tonnes or dimensions beyond standard limits. Filed with Argentine Vialidad Nacional and Chilean MOP.
How an international
crossing is coordinated.
Coordinate with the carrier
Define cargo type, dimensions, weight, origin, and destination. The carrier determines the appropriate unit and required permits.
Process customs documentation
Handle MIC/DTA, certificates, and other documents with the customs agent. Typical timeframe is 2 to 5 business days depending on cargo type.
Check Cristo Redentor Pass status
Confirm the pass is open with no active restrictions. In winter (May–September), plan alternatives via Paso Pehuenche.
Border crossing and clearance
Trucks stop at the Centro de Frontera Horcones (Argentina) and Paso Los Libertadores (Chile). Typical crossing time is 4 to 12 hours depending on customs flow.
Delivery at Chilean destination
Direct coordination with the consignee. Total door-to-door transit from Mendoza to Santiago or the port area is 12 to 24 hours.
