The UK's Trade Remedies Authority has launched investigations into imports of glass containers from China and Turkiye.

Glass containers are used across many UK supply chains (from preserves to beverages) and remain a household staple, especially given the possibility of recycling.

The two cases are:

an anti-subsidy investigation into subsidised imports of glass containers from Turkiye;

an anti-dumping investigation into imports of glass containers from China.

The investigations cover the majority of glass containers under 2.5 litres.

That means everything from the jars that keep the country’s preserves safe to the bottles that carry beer, wine, and spirits.

Full details about the products under investigation are available on the TRA’s public file. The decision to initiate the investigations followed applications lodged on behalf of the UK industry in glass containers.

TRA Chief Executives Jessica Blakely and Carmen Suarez said: "The investigations initiated today by the TRA will consider whether the UK glass industry is being harmed by unfair competition from imports and, if so, the measures to put in place to protect it."

If a business thinks it could be affected by these investigations, it can register to take part in the investigation through a public file by 20 March 2026.

Those who register after this may not be able to fully participate.

The TRA will also be holding an online drop-in session on 11 March 2026 to provide more information to businesses and to answer any questions.

The Trade Remedies Authority is the UK body that investigates whether new trade remedy measures are needed to counter unfair import practices and unforeseen surges of imports. 

The period of investigation (POI) for the investigations is 1 January 2025 to 31 December 2025. The injury period (IP) is 1 January 2022 to 31 December 2025.

Investigations typically run for up to 12 months and involve gathering evidence from UK businesses, importers, and overseas producers.

If the TRA finds harm, it can recommend measures such as duties to restore fair competition.
