New Delhi, April 6 A government body has issued notices to China, Japan and South Korea proposing to initiate a probe on the ‘dumping’ of some steel products into India. The notices have been issued for hot-rolled coils of alloy and non-alloy steel, a source at Directorate General of Anti-Dumping & Allied Duties (DGAD) said. Indian steelmakers Steel Authority of India Ltd, JSW Steel and Essar Steel had approached DGAD seeking anti-dumping duties on cheap imports flooding local markets and pressuring margins. Imports of steel into India rose 20.5 per cent in 11 months to February compared with the same period last year.
