The anti-dumping duties are extended for five years beginning from Jul 23, it said in a statement.
The anti-dumping duty rates are set at 39 per cent to 45.7 per cent for Japanese firms including JFE Steel and Nippon Steel, 37.3 per cent for Korean companies and 46.3 per cent for EU firms.
China, the world’s top steel producer launched an anti-dumping investigation in June last year into grain oriented flat-rolled electrical steel from Japan, South Korea and the EU following the expiry of tariffs in place for the past five years.
The tariffs were reinstated during the year-long investigation.
The move followed a petition by steelmakers China Baoshan Iron and Steel and a unit of Beijing Shougang which argued that ending the tariffs could lead to further dumping, hurting the domestic steel sector.
Oriented electrical steel or oriented silicon steel is used in transformers and is more expensive than carbon steel.
