Ecuador-Colombia Tariff War: Bilateral Trade Down 44% as Ecuador Prepares 100% Duties in May

Tariff Escalation Timeline

Month	Ecuador Tariff on Colombian Goods	Colombia Response
February 2026	30%	Initial retaliatory measures
March 2026	50%	Tariffs up to 75% on Ecuadorian products
May 2026	100% (planned)	Threat to cut electricity exports

The escalation has been rapid. Ecuador imposed initial tariffs in February citing border security costs, and has doubled rates twice in three months.

Trade Impact

Bilateral trade declined 44% in the first month of the tariff regime. The disruption affects major product categories in both directions:

Colombian exports to Ecuador:

• Electricity
• Pharmaceuticals
• Vehicles
• Cosmetics
• Plastics

Ecuadorian exports to Colombia:

• Vegetable oils and fats
• Canned tuna
• Minerals and metals

Border Dynamics

The Rumichaca international border crossing is experiencing increased cargo transport movement as businesses rush shipments before the next tariff increase. Truckers are paying the current 50% rate to clear goods ahead of the 100% threshold.

Ecuador has cited border security requirements of approximately $400 million across a 600-kilometer frontier as partial justification for the tariffs.

The Electricity Variable

Colombia's threat to cut electricity sales introduces a systemic risk for Ecuador's power grid. During the 2024 energy crisis, Ecuador experienced rolling blackouts of up to 14 hours daily, partly due to drought-reduced hydroelectric capacity. Colombian electricity imports were a critical supplement during that period.

If Colombia follows through, Ecuador faces potential supply shortfalls heading into the dry season — though the government has invested in emergency thermal generation capacity since 2024.

What to Watch

• May tariff implementation date. The jump from 50% to 100% will effectively close the border to most Colombian goods at commercial scale. Watch for last-minute negotiation signals.
• Colombian electricity cutoff timeline. Any reduction in cross-border electricity flows will surface quickly in grid frequency data and CENACE dispatch reports.
• Pharmaceutical supply chain. Colombian pharmaceuticals are a significant import category. The 100% tariff could disrupt medication availability — particularly relevant given ARCSA's concurrent OTC list tightening.
• CAN arbitration. Both countries are Andean Community members. Watch for formal dispute proceedings that could mandate tariff rollbacks.
• Downstream domestic effects. Colombia border trade supports economies in Carchi, Imbabura, and Sucumbíos provinces. SME impact data will emerge over the coming weeks.
