Mumbai-based Borosil Renewables has announced a 50% expansion of its manufacturing capacity of solar glass from 1,000 to 1,500 tons a day.

The company’s board of directors approved the expansion after the Ministry of Finance announced a “reference price” for solar glass imports to restrict low-cost products from China and Vietnam in December 2024.

Borosil said the reference prices between $673 and $677 for imports from China works out to a price of ₹143 (~$1.66) per mm/square meter at the container yard, which will act as a minimum threshold for import prices from China.

The ministry’s decision followed a preliminary investigation by the Directorate General of Trade Remedies in February last year, which found evidence of dumping practices.

The dumping had resulted in a significant increase in imports of these goods from these countries, both in absolute terms and in relation to domestic production and consumption, causing material injury to the domestic industry.

The investigation was conducted in response to an application submitted by Borosil Renewables, alleging similarities between its domestically produced solar glass and the imported counterparts.

The imposition of anti-dumping duties on solar glass imports has however sparked fears of solar module price hikes. Solar glass is a critical component, accounting for 8% of total module costs.

Last September, Indian manufacturers of solar ancillary components, including solar glass, urged the Ministry of New and Renewable Energy to mandate the use of domestically manufactured solar components in government projects to create a robust local supply chain and reduce the reliance on imports.

Borosil reported a net loss of ₹131.27 million (~$1.55 million) in the second quarter of the financial year 2025, attributing the loss to the slashing of free-on-board prices of solar glass from Vietnamese and Chinese exporters by up to 32% between June and September 2024.
