US Trade Investigations: A New Approach
On March 11, 2026, the US Trade Representative (USTR) announced new Section 301 trade investigations into the trade policies of 16 economies.
This action follows a US Supreme Court ruling that invalidated the previous administration's tariff strategy. The probe aims to address concerns about global manufacturing overcapacity that allegedly burdens US commerce.
Sectors Under Scrutiny in India
The investigation identifies specific sectors in India where the US perceives potential issues.
These sectors include: solar modules, petrochemicals, steel, textiles, health-related goods, construction materials and automotive products.
The US notice indicates that India’s solar-module manufacturing capacity significantly exceeds domestic demand, raising concerns about export-driven surpluses.
Section 301: How the Investigation Works
Section 301 of the US Trade Act of 1974 allows the US government to investigate and respond to foreign trade practices deemed "unreasonable or discriminatory."
The investigation will examine policies such as: industrial subsidies, state-supported manufacturing expansion, activities of state-owned enterprises and market-access barriers.
If unfair practices are confirmed, the US may impose retaliatory trade measures, including additional tariffs or trade restrictions.
Investigation Timeline and Process
The investigation will follow a strict timeline:
- Public dockets for written submissions will open on March 17, 2026.
- Written submissions and requests to participate in hearings must be filed by April 15.
- Public hearings will take place from May 5 to May 8 at the US International Trade Commission in Washington.
- Rebuttal submissions must be filed within seven days after the hearings conclude.
Tariff Strategy Collapse and Its Aftermath
These investigations come shortly after a major setback to the previous administration's trade strategy. On February 20, 2026, the US Supreme Court struck down the legal basis for "reciprocal tariffs."
Following the ruling, Washington imposed a uniform 10% tariff under Section 122 of the Trade Act of 1974. This shift created complications for countries that had already negotiated trade arrangements with the US.
Several countries, including the European Union, Indonesia, Japan, Malaysia, Cambodia, South Korea, Vietnam, Taiwan and Bangladesh, had concluded trade agreements with the US after April 2025.
India's Trade Negotiations with the US
India signed a joint statement with the US on February 6, 2026, committing to reduce tariffs, purchase US products and ease regulations.
US President Donald Trump has cautioned trading partners against renegotiating these arrangements.
Section 301 vs. Reciprocal Tariffs
The Global Trade Research Institute (GTRI) notes that Section 301 is a slower and more legally constrained trade tool than the reciprocal tariff system.
The United States may also consider tariffs under Section 232 of the Trade Expansion Act of 1962, which allows trade restrictions on national-security grounds.
"Section 301 investigations require evidence of harm and must be tied to specific trade practices."
What to Watch Next
The USTR will consult with the governments concerned and then determine whether the investigated practices warrant retaliatory action. The coming months will be critical as the investigations proceed and the potential for new trade barriers looms.
