PVTIME – The Office of the United States Trade Representative (USTR) has launched a Section 301 investigation into structural manufacturing overcapacity and overproduction. India is among the economies that will be scrutinised. Conducted under Section 301 of the US Trade Act of 1974, a key piece of legislation targeting unreasonable or discriminatory overseas trade practices, the investigation will assess whether the industrial policies and practices of the affected countries have distorted global markets and undermined US commercial interests.
The USTR’s announcement identifies solar modules, cells, energy products, and semiconductors as key sectors affected by overcapacity. It highlights a significant contraction in US domestic capacity in these areas, with some segments falling considerably behind international competitors and presenting a challenging landscape for the domestic industry.
The USTR defines structural overcapacity as an industry issue driven by government policies or support mechanisms where manufacturing capacity far exceeds domestic market demand. This imbalance leads to increased exports, suppressed global prices and puts competing businesses worldwide at a disadvantage.
Key procedural steps include formal consultations between the USTR and each economy under investigation, alongside a public comment period starting on 17 March 2026. Stakeholders may submit written comments or apply to testify in person at a hearing on 5 May 2026.
The investigation comes amid heightened global scrutiny of clean energy supply chains and national industrial support policies. As part of its broader industrial strategy, the US is increasing measures to protect domestic manufacturing capacity and reduce reliance on imports. Previously, the US used Section 301 to impose additional tariffs on key Chinese clean energy components, such as solar wafers and polysilicon.
In recent years, US trade controls on imported solar products have intensified, impacting India and other major global export regions. The latest Section 301 investigation adds further uncertainty for Indian solar exporters seeking to increase their presence in the US market.
In February of this year, the US reduced effective tariffs on relevant Indian products from 50% to 18%. At the time, industry observers cautioned that US efforts to bring manufacturing back home could limit the profitability of Indian solar exporters, given the US government’s consistent prioritisation of domestic manufacturing and supply chain security.
Notable shifts have since occurred in India’s solar trade landscape. Despite overlapping tariffs and trade barriers, the latest industry data confirms that the US remains a core export market for Indian solar modules and cells. However, exports of Indian solar products have declined sharply in the most recent quarter.
