Protecting Solar Procurement Contracts: Navigating Duties, Tariffs, and Import Bans (2026)

The solar industry is in a constant state of flux, and nowhere is this more evident than in the realm of procurement contracts. As someone who’s spent years analyzing trade policies and their impact on renewable energy, I can tell you that the current landscape is a minefield. What’s striking is how quickly the rules change—contracts that seemed solid just a year ago are now riddled with vulnerabilities. But what makes this particularly fascinating is that it’s not just about keeping up with new regulations; it’s about understanding how these regulations interact to create a cycle of risk that’s nearly impossible to escape.

The Triple Threat to Solar Procurement

Let’s start with the three main instruments shaping this chaos: antidumping and countervailing duties (AD/CVD), tariffs, and the Uyghur Forced Labor Prevention Act (UFLPA). On the surface, these seem like distinct tools, but in reality, they’re interconnected in ways that most procurement teams underestimate. Personally, I think the biggest misconception is that these are isolated challenges. In my opinion, they form a self-reinforcing cycle that’s reshaping the solar supply chain in real-time.

Take AD/CVD duties, for instance. They’ve been the driving force behind the migration of solar manufacturing from China to Southeast Asia and now beyond. What many people don’t realize is that this isn’t just a one-time shift—it’s a perpetual game of whack-a-mole. As soon as production scales up in a new region, new AD/CVD cases emerge, forcing manufacturers to relocate again. This raises a deeper question: Is there any endgame here, or are we stuck in an endless loop of relocation and litigation?

Tariffs add another layer of complexity. The Section 232 investigation, for example, frames polysilicon as a national security issue, which could add upwards of 15 cents per watt to imported modules. If you take a step back and think about it, this isn’t just about cost—it’s about redrawing the map of viable import lanes. Some routes that were economically feasible yesterday might become unsustainable tomorrow. What this really suggests is that the solar industry is becoming increasingly localized, whether it wants to or not.

Then there’s the UFLPA, which operates differently but with equally profound implications. Unlike tariffs or duties, it’s not about cost—it’s about existence. If a shipment is detained under UFLPA, it doesn’t matter how much you’ve paid or what your contract says; the product simply doesn’t arrive. A detail that I find especially interesting is how UFLPA resets the risk every time manufacturing moves. Just when you think you’ve got compliance figured out, a new relocation throws everything into question.

The Hidden Cycle of Risk

What’s often overlooked is how these instruments feed into each other. For example, every time AD/CVD cases force manufacturing to relocate, UFLPA risks are reset. This isn’t just a theoretical concern—we’ve seen it happen. When cell production moved to Ethiopia, it brought new sourcing relationships and, with them, renewed uncertainty about polysilicon origins. One thing that immediately stands out is how fragile compliance really is. It’s not a one-time achievement; it’s a moving target that requires constant vigilance.

Section 232, if enacted, will add a financial dimension to what UFLPA enforces legally. Both target supply chains linked to China, but while UFLPA stops shipments, Section 232 could make them prohibitively expensive. From my perspective, this dual pressure is pushing the industry toward a tipping point. Contracts written today might already be obsolete by the time products ship, not because of poor drafting, but because the underlying conditions have shifted so dramatically.

The Contractual Blind Spots

Most solar procurement contracts are woefully unprepared for this reality. Unnamed duties, unanticipated tariffs, and one-sided change-in-law clauses are just the tip of the iceberg. What’s more concerning is how these gaps interact. For instance, a contract that transfers title at shipment leaves buyers financially exposed if a UFLPA detention occurs. Even if the seller is eventually forced to resolve the issue, the construction schedule is already derailed—and time, as they say, is money.

Another critical oversight is the lack of teeth in UFLPA audit rights. Manufacturers often agree to audits in principle but deny access when it matters, citing upstream resistance. In my experience, this is where many buyers drop the ball. Without a termination provision tied to audit rights, you’re essentially trusting the manufacturer to police themselves—a recipe for disaster.

Building Resilience in a Chaotic Landscape

So, what’s the solution? First, contracts need to be explicit. Every applicable duty, tariff, and risk should be named and accounted for. Section 232, in particular, should be addressed proactively, whether through full seller assumption, shared responsibility, or a two-price approach. Change-in-law clauses should work both ways, ensuring buyers benefit from rate reductions just as sellers do from increases.

Title transfer and payment terms also need rethinking. A meaningful holdback until customs clearance keeps sellers incentivized to resolve detentions quickly. Liquidated damages clauses should explicitly cover delays caused by customs issues—these are foreseeable risks, not force majeure events.

On the UFLPA front, audit rights must extend across the entire supply chain, with termination rights if access is denied. This isn’t just about due diligence; it’s about leverage. If a manufacturer can’t secure consent from upstream suppliers before signing, the audit right is meaningless.

Finally, there’s the question of supplier selection. Personally, I think FEOC compliance is the best indicator of broader supply chain integrity. Suppliers who are genuinely compliant with FEOC rules tend to have cleaner polysilicon sourcing, welcome audits, and are better positioned to handle Section 232 scrutiny. It’s not just about ticking boxes—it’s about aligning with partners who understand the long game.

The Bigger Picture

If you take a step back and think about it, the solar industry is at a crossroads. The policies shaping procurement contracts aren’t just about trade—they’re about geopolitics, human rights, and national security. What this really suggests is that the industry’s future isn’t just in the hands of manufacturers or buyers; it’s being shaped by forces far beyond their control.

In my opinion, the only way forward is to embrace this complexity. Contracts need to be dynamic, not static. Procurement teams need to think like strategists, not just negotiators. And most importantly, the industry needs to recognize that resilience isn’t about avoiding risk—it’s about adapting to it. The landscape will never stop moving, but with the right approach, we can stay one step ahead.
