The TRA has initiated a new dumping investigation into imports of S-PVC from China, Mexico, and South Korea.
The Trade Remedies Authority has initiated a dumping investigation into imports of suspension polyvinylchloride (S-PVC) from China, Mexico, and South Korea.
The investigation follows an application from INOVYN ChlorVinyls Ltd, the UK's only producer of S-PVC. The application alleges that dumped imports of S-PVC from China, Mexico, and South Korea are causing injury to UK industry.
INOVYN produces S-PVC at its Newton Aycliffe site in County Durham. The company also has UK sites in Runcorn and Northwich in Cheshire.
S-PVC is used to make products such as pipes, window frames, cables, flooring and packaging.
This investigation will examine whether dumped imports from China, Mexico, and South Korea are harming the UK's S‑PVC industry. If injury is found and a trade remedy is recommended, it could help ensure the UK producer is able to compete fairly and support the long-term resilience of the UK chemicals sector. The UK chemicals sector has been identified by the Government as strategically important, with a £350 million Critical Chemicals Resilience Fund announced earlier this year to help strengthen critical supply chains and support key producers.
If the TRA recommends a trade remedy, it will carry out an economic interest test to assess whether the remedy is in the UK's economic interest.
If your business may be affected by this investigation, you can register to take part by 21 August through the Trade Remedies Service, our application portal .
