On April 2, 2025 the US announced radical changes to tariffs on all imports into the United States. US polyethylene imports from and exports to Canada and Mexico are under the US-Mexico-Canada Free Trade Agreement and are not impacted by the new tariffs. US exports of polyethylene, however, have risen rapidly since 2021 on higher shipments to Asia-Pacific, Latin America, Western Europe, and other regions. Responses, if any, by trading partners against imports of polyethylene or other products from the US are evolving. On April 3, China said it would apply a 34% tariff on all imports from the US.
