So far this year, the U.S. International Trade Commission has published multiple determinations related to packaging products or materials.
These come on top of the commission’s December determination that thermoformed molded fiber products imported from China and Vietnam were being sold into the United States at less-than-fair value, resulting in the Department of Commerce issuing antidumping and countervailing duties that took effect Jan. 27.
Here are the other recent packaging-related cases:
Polypropylene corrugated boxes from China
USITC determined in February that a U.S. industry is materially injured by imports of PP corrugated boxes from China, which Commerce has determined are sold in the U.S. at less-than-fair value and subsidized by the Chinese government. The initial case also looked at these products imported from Vietnam. Next, Commerce will issue an antidumping duty order and a countervailing duty order on these imports from China.
Plastic product producer Inteplast Group was among the companies that submitted petitions for USITC to investigate this matter in May 2025. Inteplast told Packaging Dive via email that it submitted its request because of concerns with the substantial growth in low-priced imports since 2022. The company anticipates any duties imposed would help restore balance within the market and relieve pricing pressure for domestic producers.
“We are confident the investigation will provide a fair and thorough assessment of the competitive conditions faced by domestic manufacturers,” said Karen Dicang, Inteplast’s senior director of sales and marketing, sustainable packaging and printing solutions.
PET film, sheet and strip from China, India, Taiwan and United Arab Emirates
USITC decided to keep in place its existing orders regarding the imports of these products harming U.S. companies. The commission made its decision after a mandatory five-year review that requires Commerce to revoke such ongoing duties unless USITC finds that revocation would likely lead to further material dumping. In these expedited reviews, the agency typically does not conduct a full investigation with hearings and questionnaires; rather, it generally solicits responses regarding likely effects of a revocation, and within 95 days decides whether a full review is necessary.
In December, USITC decided an expedited review was adequate for the PET films case, and last week it publicly announced a continuation of the orders for antidumping duties on these products imported from the four named countries. Polyplex USA, Terphane and Mitsubishi Chemical America are among the companies that engaged with USITC for this case.
Lightweight thermal papers from China
Similar to the PET film case, this was an expedited five-year review of existing duties. USITC published its determination in January that found sunsetting the duties likely would harm U.S. businesses. While thermal papers often are used for retail receipts, certain types also are used for package labels. The commission received one response, from Domtar, during the comment period it opened in June 2025.
Beverage brewing products and components
USITC decided in February to formally launch an investigation into whether a U.S. company is importing certain reusable pods and filters, typically used for brewing single servings of coffee, in violation of U.S. trade law. Specifically, the claim is for an alleged violation of section 337 of the Tariff Act of 1930, which targets intellectual property infringements for imported products.
Adrian Rivera Maynez Enterprises filed the petition with patent violation claims against fellow California company Denys Orlov, which does business under the name GoodCups. Adrian Rivera Maynez Enterprises requests that USITC issues to the accused a limited exclusion order and cease and desist orders, which could prevent the products from entering the U.S.
