Trump Signs Proclamation: US Reduces Tariffs to 15% on Select Industrial and Agricultural Equipment

In a significant but carefully targeted adjustment to America's trade policy, US President Donald Trump signed a proclamation on June 1, 2026, reducing tariffs on a specific basket of industrial and agricultural equipment that contains substantial quantities of steel, aluminium, or copper. The new tariff rate of 15% — down from the previous 25% — will come into effect for goods imported or withdrawn from bonded warehouses after 12:01 a.m. EST on June 8, 2026, and will remain in force until December 31, 2027. Delhi-based think tank GTRI (Global Trade Research Initiative) has analyzed the move, noting that while it delivers some relief, the benefits for countries like India are expected to be modest and limited in scope.

What Is Section 232 and Why Does It Matter?

Section 232 of the US Trade Expansion Act of 1962 grants the President of the United States the authority to bypass Congress and impose or adjust tariffs on specific imports if the Department of Commerce determines that those imports pose a threat to national security. It is the legal foundation upon which the US has levied duties on steel, aluminium, and copper imports for several years. The latest proclamation is an amendment to existing Section 232 tariffs — not a repeal — and it introduces a more nuanced, tiered tariff structure designed to differentiate between raw metals and the finished equipment that uses them as inputs.

For a deeper understanding of how Section 232 tariffs operate within the broader US trade law framework, the Reuters reporting on Trump's June 1 proclamation provides comprehensive coverage of the policy and its immediate market implications.

Which Products Now Qualify for the 15% Reduced Tariff?

The proclamation introduces a Temporary Reduction List of Steel and Aluminium Derivative Products, covering a range of capital-intensive industrial and agricultural equipment. According to the White House statement and GTRI analysis, the following product categories now qualify for the reduced 15% tariff rate:

  • Heating, Air-Conditioning, and Ventilation (HVAC) Equipment — including residential and commercial systems
  • Agricultural Machinery — including combines, harvesters, and related farm equipment
  • Mobile Industrial Equipment — bulldozers and forklifts, specifically when imported from trade deal countries entitled to such treatment
  • Certain Electrical Grid Equipment — components used in power transmission and distribution infrastructure
  • Selected Engineering Goods — other capital equipment with significant metal content falling within the defined categories

The White House stated that the goal of the tariff reduction is to "more effectively address national security threats, spur investment in American agriculture, housing, and manufacturing" — recognizing that excessive input costs on downstream equipment were slowing investment across key domestic sectors.

The New Three-Tier Tariff Structure Explained

The amended proclamation creates a three-tier tariff structure for steel, aluminium, and copper-containing imports, replacing the previously simpler flat-rate approach:

  • 50% Tariff: Continues to apply on raw steel, aluminium, and copper imports, as well as articles made almost entirely of these metals. This rate remains unchanged and applies to the full customs value of the product.
  • 25% Tariff: Applies to most derivative products that are substantially made from steel, aluminium, or copper but do not fall into the reduced-rate equipment categories.
  • 15% Tariff: The new reduced rate, applicable to specific categories of metal-intensive industrial and agricultural equipment listed above, effective June 8, 2026, through December 31, 2027.
  • 10% Tariff (New Provision): A newly introduced incentive rate for foreign companies whose capital equipment is manufactured using at least 85% US-origin steel, aluminium, or copper by weight. This provision is designed to incentivize foreign manufacturers to source metals from the United States.
  • 0% / Exempt: Products containing 15% or less steel, aluminium, or copper by weight are now fully exempted from Section 232 tariffs, eliminating what had been an unintended burden on goods with only minimal metal content — such as perfume bottles with aluminium caps or dental floss containers with small steel cutting blades.

New Categories Added at 25%: Steel Racks and Aluminium Lithographic Plates

The proclamation is not purely a tariff-cutting measure. Alongside the reductions, two new product categories have been added to the 25% duty list: steel racks and aluminium lithographic plates. This reflects the administration's broader strategy of using Section 232 selectively — offering relief in sectors critical to industrial expansion while tightening duties where domestic production priorities dictate.

What Does GTRI Say? Impact on India

Think tank GTRI (Global Trade Research Initiative), founded by trade expert Ajay Srivastava, was among the first to analyze the proclamation from India's perspective. GTRI's assessment is cautiously optimistic — acknowledging some potential gains while clearly flagging the structural limitations of the relief for Indian exporters.

According to GTRI, Indian exporters in the following sectors could benefit from the new 15% tariff rate:

  • Engineering goods manufacturers
  • HVAC equipment exporters
  • Electrical equipment producers
  • Agricultural machinery exporters (combines, harvesters)

However, GTRI was clear-eyed about the limitations: "The core issue remains unchanged: Indian exports of steel, aluminium and copper products continue to face sectoral tariffs of 50%, while many downstream metal products remain subject to a 25% duty." Furthermore, the 10% preferential rate for products using US-origin metals offers little practical value for Indian manufacturers, as US steel and aluminium are significantly more expensive than alternatives available to Indian producers. The EEPC (Engineering Export Promotion Council) chairman Pankaj Chadha echoed this view, noting that India is not a major exporter of agricultural machinery, which limits the direct benefit from that specific tariff reduction.

Critically, the 15% mobile industrial equipment rate (bulldozers, forklifts) applies only to "trade deal countries entitled to such treatment" — and since India does not currently have a bilateral free trade agreement with the United States, this benefit does not automatically extend to Indian exporters of those products. This makes the ongoing India-US bilateral trade pact negotiations all the more important as a pathway to securing fuller access to these reduced tariff categories in the future.

Strategic Context: India-US Trade Deal Negotiations

The tariff adjustment comes at a particularly significant moment — an Indian negotiating team is actively engaged in discussions with US counterparts toward a bilateral trade agreement. GTRI has previously advised that India should use these ongoing FTA negotiations as strategic leverage to press for the elimination or meaningful reduction of Section 232 tariffs on steel and aluminium as part of any final deal. Securing that concession could give Indian exporters of industrial and agricultural equipment full access to not just the 15% tier, but potentially even more competitive rates.

The proclamation is widely seen as part of the Trump administration's broader strategy to limit collateral damage from its ongoing trade wars, which have driven up input costs for American farmers, construction companies, and manufacturers — while maintaining maximum pressure on core metal imports through the unchanged 50% tariff on raw steel, aluminium, and copper.
