There have been three price increase announcements by the majority producers of containerboard in just five months; most recently PCA’s announcement of a $140/ton (liner and medium) increase effective September 1, 2026; IP announced $80/ton for September 1, 2026, and Smurfit Westrock announced $100/ton. These latest announcements all took place within 3 days of each other. AICC believes these increases are without economic justification based on current rawmaterial inputs and economic data. Producers cite (as they have, again without objective justification,and unconvincingly in such a relatively short period of time in between them) economic need, high operating rates (e.g., Inflation, fuel, labor, insurance), and tight supply to justify these increases. AICC is skeptical of these reasons in the current containerboard and corrugated market. Arguably, the increases are reflective of a small group of producers having market dominance.
