The United Kingdom initiated a safeguard investigation into imports of certain polyethylene terephthalate (PET) products, according to a notification to the World Trade Organization (WTO). This action was formally commenced on August 5, 2026.

The WTO's Committee on Safeguards received the notification from the United Kingdom on the same day the investigation began. This committee is responsible for overseeing the implementation of the WTO's Agreement on Safeguards.

Safeguard investigations are typically launched by a country to determine if increased imports of a particular product are causing or threatening to cause serious injury to its domestic industry. The outcome can lead to temporary restrictions on imports.

Polyethylene terephthalate, commonly known as PET, is a widely used plastic resin. It is utilized in various applications, including packaging for beverages, food, and other consumer goods, as well as in fibers for textiles.
