USITC launches antidumping probe into pizza box imports from three countries

A Firm Stance on Fair Trade in Corrugated Packaging

The U.S. corrugated packaging sector is drawing a hard line on international trade practices. The U.S. International Trade Commission (USITC) and the Department of Commerce have officially opened preliminary antidumping and countervailing duty investigations into corrugated pizza boxes imported from China, Malaysia, and Turkey. This move signals a critical moment for domestic converters and manufacturers who have been navigating an increasingly complex global supply chain throughout 2026.

The Catalyst Behind the Investigation

The trade action was initiated following a comprehensive petition filed by the American Pizza Boxes Manufacturers Coalition. This group is spearheaded by industry heavyweights Smurfit Westrock and Pratt Industries, alongside the United Steelworkers union. According to the coalition, the domestic market has been severely disrupted by a staggering 130% surge in unfairly traded pizza box imports from these three nations between 2023 and 2025, a trend that has continued to accelerate into the current year.

The coalition argues that these pricing strategies have caused significant declines in domestic production, shipments, and overall profitability for U.S. corrugated plants. By leveraging their scale and market presence, Smurfit Westrock and Pratt Industries are taking a proactive approach to safeguard the integrity of the North American packaging manufacturing base.

Analyzing the Alleged Dumping Margins

The figures presented in the petition highlight a stark disparity in global pricing models. The coalition claims that foreign producers are dumping boxes in the U.S. at margins that make fair competition nearly impossible:

• China: Alleged dumping margins ranging from 96.62% to an astonishing 568.5%.
• Malaysia: Alleged margins sitting at 110.73%.
• Turkey: Margins ranging from 120.65% to 210.37%, coupled with additional countervailing duty petitions targeting alleged foreign government subsidies.

Market Implications and Next Steps

For the converting and corrugated board industry, this is far more than a localized dispute. Pizza boxes—typically manufactured as B, C, D, or E-flute die-cut blanks—represent a massive, high-volume segment of the food service packaging market. The USITC is expected to issue a preliminary determination by October 26, 2026. If the commission rules affirmatively, importers could face immediate duty deposits. This would fundamentally shift supply chain dynamics, likely tightening domestic supply in the short term but ultimately driving volume back to U.S. corrugators.

As the industry continues to prioritize sustainable, circular economy models, ensuring that imported products compete on a level playing field is essential for maintaining the economic viability of domestic recycling and paperboard manufacturing infrastructure.

Protecting domestic manufacturing integrity ensures that forward-thinking companies like Smurfit Westrock and Pratt Industries can continue investing in high-quality, sustainable corrugated infrastructure without being undercut by artificially deflated pricing. Will this trade action prompt major fast-food chains to permanently localize their packaging sourcing, or will it simply shift the import focus to new, untargeted regions?
