India’s Ministry of Finance has announced the imposition of definitive anti-dumping duties for five years on solar glass products originating in or exported from China and Vietnam, effective retroactively from December 4, 2024. The duty rates range from 570 to 664 per metric ton and apply to patterned tempered glass (whether coated or uncoated) with a light transmittance of not less than 90.5%, a thickness not exceeding 4.2 millimeters, and any side exceeding 1,500 millimeters in length.
In its notification, the Ministry of Finance highlighted that during the investigation period, the volume of dumped imports of the relevant products from China and Vietnam surged significantly “both in absolute terms and relative proportions,” and these products were exported to India at dumped prices, causing material injury to the domestic industry. The decision follows an investigation initiated by the Directorate General of Trade Remedies (DGTR), under India’s Ministry of Commerce and Industry, in response to a petition filed by Borosil Renewables Limited, a domestic solar glass manufacturer.
Borosil welcomed the government’s decision, stating, “We firmly believe this move will restore fair competition, create a level playing field for domestic manufacturers, and accelerate the rapid expansion and exponential growth of India’s solar glass industry.”
Borosil currently boasts a solar glass production capacity of 1,350 tons per day, equivalent to an annual capacity of approximately 8.5 GW, serving over 100 customers. The company also operates a 350-ton-per-day facility in Germany, comprising two production lines operated by GMB. However, GMB incurred losses in the first half of the fiscal year ending September 30, 2024, due to substantial dumping of solar modules from Southeast Asia, sluggish European market demand, and the government’s lack of support for domestic module manufacturing. As a result, GMB’s German production lines have been fully suspended.
Despite these challenges, Borosil remains optimistic about the industry’s prospects and plans to expand its total capacity to 1,850 tons per day, equivalent to an annual capacity of approximately 12 GW, by the end of 2026. The company stated, “The expansion plan has been promptly restarted following the implementation of the anti-dumping duties.”
According to Borosil’s financial results, in the fourth quarter of fiscal year 2025 (ending March 31, 2025), the company’s operating revenue increased by 43.9% year-on-year and 18.9% quarter-on-quarter. For the full fiscal year 2025, revenue grew by approximately 12% year-on-year. The company attributed this growth primarily to a 10% increase in sales volume and a 2% rise in selling prices. However, export sales for fiscal year 2025 declined to INR 9.17 billion (approximately 11.05 million), down from INR 19.97 billion (approximately 24.06 million) in the previous year. Borosil attributed this drop to a sharp decline in European market demand, particularly due to the impact of Chinese dumped low-priced modules, and reduced installations in Turkey.
Although FOB prices fell by 32% in the first eight months of 2024 due to dumped Chinese products, Borosil noted that prices began to recover following the implementation of provisional anti-dumping duties on December 4, 2024.
