The United Kingdom Initiates Antidumping Duty Investigation into Linear Low-Density Polyethylene from the United States
On July 1, 2026, the United Kingdom’s Trade Remedies Authorities initiated an antidumping (AD) investigation into imports of linear low-density polyethylene (LLDPE) from the United States. If an affirmative decision is issued in this investigation, duties may be imposed on subject U.S. exports.
What is an antidumping duty (AD) investigation?
An AD investigation assesses whether foreign goods imported into a country are being sold at less than fair value (below prices or costs) in the domestic market (i.e., being dumped) and whether this is causing or threatening to cause injury to the domestic industry.
How can I participate?
U.S. companies involved in the production, sale, or distribution of the subject goods should register as interested parties as soon as possible. Registration is the first step in protecting your rights in a foreign trade remedy proceeding. Doing so allows you to access the case records and submit information and comments, ensuring that your views are considered. Please follow the directions outlined on page five of the Initiation Notice for instructions on how to register as an interested party in this proceeding.
