Introduction
The United Kingdom has initiated a safeguard investigation into imports of certain polyethylene terephthalate (PET), according to a notification submitted to the World Trade Organization (WTO) Committee on Safeguards on 5 August 2026.
The investigation was launched by the UK on the same day and is being conducted by the Trade Remedies Authority (TRA). The probe will examine whether increased imports of the product are causing, or threatening to cause, serious injury to the UK domestic PET industry.
At this stage, the UK has not imposed a safeguard duty or import restriction. Any safeguard action would depend on the findings of the investigation.
Investigation Covers Virgin and Recycled PET
The investigation covers certain virgin polyethylene terephthalate (vPET) and recycled polyethylene terephthalate (rPET) with a viscosity number of 74 ml/g or higher. The products are currently classified under UK tariff codes 39076100 and 39076900.
The TRA will examine developments during the period from 1 January 2021 through 31 December 2025. A safeguard investigation examines whether increased imports are causing or threatening serious injury to domestic producers. Unlike anti-dumping proceedings, a safeguard investigation does not require a finding that imports were dumped or unfairly priced.
Exporters and Interested Parties Can Participate
The UK has invited exporters, importers and other interested parties that may be affected by the investigation to participate and submit their views and evidence.
Businesses that want to take part must register through the UK Trade Remedies Service, and submit their comments by 23:59 UK time on 19 August 2026. They can also request a hearing through the service.
The TRA has encouraged WTO members to make the investigation details and participation deadlines known to exporters that could have an interest in the proceedings.
Businesses participating in the investigation may submit relevant information and evidence concerning imports, market conditions and the potential impact of any future safeguard action.
Potential Impact on PET Trade
The investigation could affect businesses exporting PET to the UK, as well as importers and companies that rely on PET as an input. If the TRA finds that increased imports are causing, or threatening serious injury and the legal conditions for safeguard action are met the UK could introduce a temporary measure to restrict imports.
A preliminary determination is expected in December 2026, if required, while the final determination is estimated for June 2027. These dates may change as the investigation progresses.
For now, businesses involved in the UK PET trade should monitor the proceedings and consider participating before the 19 August 2026 deadline. The WTO notification is available as G/SG/N/6/GBR/2.
