Before the Section 232 tariff announcement, many module buyers were anticipating a roughly $0.03/W to $0.05/W impact, with $0.06/W to $0.07/W generally seen as an upper-end outcome. A consensus formed around a more stringent pricing impact. While the ultimate clearing price remains uncertain, we believe the low end of pricing across the value chain could rise by roughly $0.14/W for modules, $0.11/W for cells, and $0.10/W for wafers. Before Section 232, imported module pricing ranged from approximately $0.24/W for fully imported products to roughly $0.43/W for imported wafers converted into US-made cells and modules.
The key question is whether higher pricing results in demand destruction or simply project delays. We estimate that a $0.10/W increase in module pricing translates into approximately $4/MWh to $5/MWh in additional power purchase agreement (PPA) pricing. Since many developers had contemplated only $0.06/W to $0.07/W of module inflation, the eventual impact of Section 232 could force some projects to renegotiate PPAs.
Trade enforcement
The US Department of Commerce and US Customs and Border Protection have reportedly been preparing for implementation for months. As a result, we do not expect significant stockpiling between now and December. Importers are likely to face heightened documentation requirements and audits, making warehouse strategies riskier than during the Biden administration’s two-year moratorium on collecting duties on imported cells and modules.
The proclamation also includes an important “tuning mechanism” that allows the commerce secretary to adjust minimum import prices without requiring another presidential proclamation. This gives the administration a relatively rapid way to respond if market pricing or trade flows develop differently than expected.
Price floor
The mechanics of the minimum import price (MIP) are important. Using an example of a module entering the United States at $0.28/W against a $0.38/W MIP, the importer would owe a $0.10/W equalizing duty plus a 15% ad valorem tariff, or approximately $0.042/W. That results in a landed cost of roughly $0.422/W.
Once the module enters the United States, certification requires the first arm’s-length sale to occur at no less than $0.38/W. In practice, this means discounting below the floor does not benefit the buyer, as the discount is largely transferred to the US Treasury through the equalizing duty.
The economic incentive therefore pushes foreign suppliers toward pricing directly at the MIP rather than selling below it. This mechanism could pull transactions toward approximately $0.38/W and potentially higher depending on market conditions.
This also changes our earlier view that importers might be able to capture significant profits by buying below the MIP and reselling at the floor.
Finally, we believe Section 232 could prove more durable across political administrations than some investors expect. The policy is explicitly designed to incentivize additional US ingot, wafer, and cell capacity. If it succeeds in creating meaningful domestic investment and employment, a future Democratic administration may have limited incentive to unwind it.
