India has imposed an anti-dumping duty on solar glass originating in or exported from China and Vietnam for a period of 5 years. The duty has been levied from December 4, 2024, according to a Ministry of Finance notification dated May 8, 2025.
The tariffs range from $570/MT to $664/MT on textured toughened (tempered) glass with a minimum of 90.5% transmission of thickness not exceeding 4.2 mm, and where at least one dimension exceeds 1,500 mm, whether coated or uncoated.
In its notification, the ministry says that there is a substantial increase in the volume of dumped imports of subject goods from subject countries over the injury period in ‘absolute and relative terms’ as the products were exported to India at dumped prices. Due to this, the domestic industry has suffered material injury.
The Finance Ministry’s decision follows an investigation by the Directorate General of Trade Remedies (DGTR) following a request by Indian solar glass producer Borosil Renewables Limited.
Borosil welcomed the decision saying, “We firmly believe that while restoring fair competition and creating a level playing field for domestic manufacturers, this will encourage rapid and significant growth in Domestic manufacturing of solar glass, leading to exponential growth in India’s solar glass industry.”

The company currently operates a total 1,350 tons per day (TPD) of solar glass production capacity, equivalent to 8.5 GW annual capacity, supplying to more than 100 domestic customers. Its total capacity also comprises a 350 TPD furnace in Germany with 2 production lines operated by GMB. Citing low demand for solar in Europe due to large-scale dumping of solar modules from Southeast Asia, and the lack of government support for domestic module manufacturing, among other factors, Borosil says GMB incurred a loss during H1 (period ending September 30, 2024).
The GMB lines are completely closed at present, but Borosil is buoyant about the future prospects of the industry, going by the growth in module manufacturing.
By CY 2026, it aims to expand its total production capacity to 1,850 TPD, equivalent to 12 GW capacity. “The expansion plan has been re-activated immediately upon imposition of Anti dumping duty on imports of solar glass,” stated the manufacturer.
During Q4 FY25 (period ending March 31, 2025), Borosil reported a 43.9% year-on-year (YoY) and an 18.9% quarter-on-quarter (QoQ) growth in its revenues, while annual sales for FY2025 grew by about 12%. The company attributes the growth in numbers to the 10% increase in sales volume and the 2% increase in selling price.
Borosil’s export sales during the reporting year declined to INR 9.17 billion ($11.05 million), compared to INR 19.97 billion ($24.06 million) last year. The company attributes this decline to the significant drop in demand in the European markets due to Chinese modules dumped at artificially low prices, apart from reduced installations in Turkey.
While FOB prices were down by 32% in the initial 8 months of the year due to dumped Chinese products, Borosil says prices went up after the imposition of a provisional duty on Chinese and Vietnamese imports from December 4, 2024.
