Judge allows containerboard price-fixing suit against PCA to proceed

A US federal judge has denied motions by North American containerboard producers, including Packaging Corporation of America, to dismiss an antitrust lawsuit filed in July 2025 by Artuso Pastry over six lockstep or near-lockstep price increases. Ten defendants, among them PCA and three Cascades entities, must answer the complaint by 29 September 2026 and file a joint status report with discovery dates the following week. Graphic Packaging International and Smurfit Westrock were dismissed late last year on grounds the court did not state.

Why this mattersThe case moves to discovery, exposing containerboard producers to damages claims and scrutiny of a market the plaintiff says five players now control with at least 85% share.
