Can I sue a supplier in Paraguay for fixing prices with competitors and overcharging my shop?

In Paraguay
Last Updated: Feb 27, 2026
I run a small retail shop in Asunción and noticed several suppliers raised prices the same week with identical terms. I suspect they coordinated and it has hurt my margins for months. What evidence do I need and where would an antitrust claim be filed in Paraguay?

In Paraguay, potential price coordination between suppliers may fall under competition law. You should gather evidence of parallel pricing, communications with suppliers, price lists, contracts, invoices, and any indication of coordination. Complaints are typically filed before the Comisión Nacional de la Competencia (CONACOM), which investigates anticompetitive conduct. If damages are claimed, a civil action for compensation may also be pursued after or alongside the administrative process.
