The United States has imposed preliminary duties of 126 per cent on solar imports from India, marking a sharp escalation in trade tensions within the renewable energy sector.
The decision, announced by the US Commerce Department, follows its determination that Indian manufacturers benefited from unfair government subsidies that enabled them to undercut American producers.
The move places India among a group of Asian exporters facing steep penalties. Initial duties range from 86 per cent to 143 per cent for Indonesia and 81 per cent for Laos, reported Bloomberg.
According to US authorities, these rates reflect the extent of foreign subsidies that distorted market competition and disadvantaged domestic solar manufacturers.
What Triggered The Investigation?
The probe was initiated after a petition by the Alliance for American Solar Manufacturing and Trade, a US industry group that sought protection for domestic producers. The group argued that heavily subsidised imports were distorting the market and threatening investments in local manufacturing.
“Today’s finding is an important step toward restoring fair competition in the US solar market,” said Tim Brightbill, co-chair of Wiley Rein’s International Trade Practice and lead attorney for the Alliance. “American manufacturers are investing billions of dollars to rebuild domestic capacity and create good-paying jobs. Those investments cannot succeed if unfairly traded imports are allowed to distort the market.”
The final determination in the investigation is scheduled for July 6. In parallel, the Commerce Department is also conducting an antidumping duty probe into solar cells imported from India, Indonesia and Laos.
Why India Matters In The US Solar Supply Chain
India has emerged as a significant supplier to the US solar market in recent years. Solar imports from India were valued at $792.6 million in 2024, more than nine times the value recorded in 2022, according to Commerce Department data.
The growth reflects a broader reshuffling of supply chains after the US previously imposed steep duties on four Southeast Asian nations that once dominated imports.
In the first half of 2025, India, Indonesia and Laos together accounted for 57 per cent of solar-module imports into the US, according to BloombergNEF. As developers diversified away from earlier restricted markets, these countries gained prominence as alternative sourcing hubs. The newly announced duties could disrupt that balance.
Separate From Broader Trump Tariffs
The solar duties are distinct from the sweeping global tariffs previously introduced by US President Donald Trump under separate legal authority. Those broader tariffs were struck down by the US Supreme Court last week. In response, Trump introduced fresh 10 per cent tariffs, which he has indicated could rise to 15 per cent.
Earlier this month, the US and India struck a bilateral trade deal aimed at easing economic friction between the two countries. The imposition of these preliminary duties, however, adds a layer of complexity to that relationship, particularly in the fast-growing clean energy segment.
Impact On Industry And Consumers
While the duties are intended to support American solar manufacturers, they also inject uncertainty into a sector that has faced fluctuating policy signals. The US solar industry, which depends heavily on imported components, could see higher costs for developers and ultimately for consumers.
By targeting what it describes as unfair subsidies, the US aims to strengthen domestic manufacturing capacity. At the same time, elevated import costs risk slowing project pipelines and increasing installation expenses.
