Mexico to Pay Under 1% of $1.7B Vulcan Materials Arbitration Claim

Mexico Vulcan Materials arbitration CIADI $15 million payment

An international arbitration tribunal administered by the Centre for International Dispute Settlement (CIADI) dismissed almost all of the claims filed by U.S. quarrying firm Vulcan Materials Company against the Mexican government. Only a single claim relating to the January 2018 closure of a limestone quarry operated by its subsidiary Calizas Industriales del Carmen (Calica) in Quintana Roo was upheld, representing less than one percent of the $1.7‑$1.9 billion compensation the company originally sought.

Mexico’s Economy Ministry said the payment will total roughly $15 million. The Mexican authorities had ordered the quarry’s closure, citing severe environmental damage such as the destruction of cenotes and contamination of groundwater. The former mining site has since been designated an environmental protection zone. The arbitration was launched in 2018 under the North American Free Trade Agreement, now succeeded by the United States‑Mexico‑Canada Agreement (USMCA/T‑MEC). The government said it will review the decision for any further legal steps while reaffirming its commitment to foreign investment and treaty obligations.
