India extended a tariff on steel imports for three years, marking the nation’s latest effort to shield its domestic industry from a glut.

An import levy of 11% to 12% was proposed for some products, the finance ministry said in an order on December 30. The measures were first introduced in April for 200 days.

India is the latest country to respond to a global oversupply that’s driven prices to multi-year lows, with elevated flows from China. A surge in cheap imports from the top producer has hurt local producers, including JSW Steel Ltd., while forcing some smaller mills to shut down even as domestic demand stays firm.

India’s steel industry has expanded rapidly over the past decade, yet its output remains just a fraction of China’s. Producers are betting on long-term gains driven by accelerating urbanization and industrial growth. The duty offers long-awaited relief for mills, which have been pushing for action.

Indian steelmakers’ shares rose on December 31, with state-owned Steel Authority of India Ltd. gaining as much as 4.2%., Tata Steel Ltd. up as much as 3.2%, and JSW Steel rallying more than 5%.
