Section 232 is signed. Here's what changes, what doesn't, and what comes next.

For two years, "build a resilient supply chain" was advice. On August 6, it became arithmetic.President Trump signed a proclamation imposing a 15% tariff on polysilicon derivatives — ingots, wafers, cells, and modules — along with minimum import prices at every stage of the supply chain.

Everything takes effect at 12:01 a.m. ET on December 4, 2026.

It's more than a tariff. It's a price floor enforced through the tariff system.

That distinction matters more than the 15%.A tariff adds cost. A minimum import price sets a price that imported product cannot go below, regardless of what an exporter is willing to accept. The policy is designed to establish a protected price floor for imported product and improve the commercial viability of U.S. production. The spread many buyers have been underwriting against — imported product versus domestic — is being narrowed by design, at every stage of the stack.

The exposure most buyers haven't modeled yet

Here's what's getting lost in the coverage: Section 232 reaches cells and wafers, not just finished modules.A U.S. module assembly does not eliminate exposure to the Section 232 measures if the cells or other covered inputs are imported. If the cells inside it were imported, exposure exists at the cell stage before that module ever reaches a rack. "Assembled in America" and "unaffected by Section 232" are two different claims — and after December 4, the difference shows up on an invoice.

Which is why the questions worth asking every supplier this month are simple ones:

1. Where is every step actually performed?Not where it was assembled. Polysilicon, ingot, wafer, cell, module — five answers, not one.

2. What is your strategy after December 4?Not just what happens to next quarter's price. What is the plan for 2027 and beyond, and who is executing it?

3. Can you show me the documentation, not describe it?Origin documentation now carries direct financial weight. There's a meaningful difference between a supplier who says their file is clean and one who hands it to you.

If a supplier can't answer all three in writing, they either haven't done the work or would rather not share it. Both are informative.

A note on the temptation to stockpile

Buying ahead may create an opportunity in some circumstances, but it isn't a strategy by itself. The proclamation contains specific rules for goods covered by pre-August 6 contracts, and the treatment of inventory depends on how and when goods are entered for consumption.

The better question isn't simply how much product can be placed in a warehouse before December 4. It's whether the supply strategy remains economically and operationally sound after the new rules take effect.

Our position rests on three things, and we'd rather describe them accurately than dramatically.

Where we stand

Module assembly in Texas is where our answer starts. It isn't where it ends.

A U.S. assembly line is table stakes after December 4. What determines whether a supplier can hold a price is what sits upstream of that line — and how much of it they control.

Tomball is producing now. 7,200 modules per day today, with our expansion to 4 GW underway and on track to come online ahead of December. We are not reacting to this policy. We have been building toward the market it creates.

Long-term commitments with domestic cell partners. Cells are where Section 232 bites hardest and where most "American-made" claims get thin. Our commitments upstream are structured for duration, not for this quarter — which is what makes a price durable rather than a snapshot.

Control of our own wafer sources. This is the part that rarely gets discussed and matters most. The MIP creates a spread at every stage of the stack. Controlling wafer sourcing means we manage that spread deliberately instead of absorbing whatever the market hands us — and it's the difference between a supplier who can explain their pricing to you and one who can only pass it along.

A transparent, flexible supply chain — domestically and globally. We can tell you where every stage of our product comes from, and document it. That's been true since before this proclamation existed, because we built our documentation practice for FEOC and domestic content scrutiny ahead of the requirement. We're also not dependent on a single geography to serve U.S. demand, and we continue to develop that footprint in new regions. More on that soon.

We're continuing to strengthen this position ahead of December 4, and we won't announce agreements before they exist. But if your projects depend on the answer, we'll talk with you candidly about where things stand.

What's next

The most common question we're hearing right now isn't about the tariff. It's "what happens after?"

That's the right question, and it deserves a real conversation rather than a paragraph in a newsletter. A lot of buyers are using the runway to December 4 to reset — re-evaluating every option on the table rather than defaulting to last year's assumptions. If that's where you are, we'd like to be on your list.
