China's Ministry of Commerce announced on Saturday that it will extend anti-dumping duties on imports of alloy-steel seamless pipes for high temperature and pressure from the United States and the European Union for another five years.

Following an expiry review launched at the request of the domestic industry, the extension will take effect from May 10, the ministry said in a statement on its website.

China started to impose anti-dumping duties on imported alloy-steel seamless pipes for high temperature and pressure from the United States and the European Union in 2014. In June last year, the commerce ministry adjusted anti-dumping duty rates for producers of such products from these regions.
