The credit only matters if someone books it — and the same is true of a duty. On June 12, 2026, the Commerce Department's International Trade Administration published the preliminary results of its countervailing-duty administrative review on crystalline silicon photovoltaic cells from China, covering calendar-year 2023, under order C-570-980. The headline finding is blunt: Commerce preliminarily determines that countervailable subsidies were provided to Chinese solar-cell producers and exporters during the period of review. It also states an intent to rescind the review, in part, for the companies listed in its Appendix III.
This is the document, not the press release, and it is worth being precise about what it is. A countervailing-duty (CVD) order is the standing trade remedy; an administrative review is the annual exercise in which Commerce recalculates the subsidy margins for a specific 12-month window and the specific firms under review. The 2023 review's preliminary results do two things: they reaffirm, on a preliminary basis, that the subsidization Commerce has long found in this order continued through 2023, and they tee up a partial rescission for certain firms that drop out of the review's scope.
Why this order matters to the U.S. solar market
Statute meets balance sheet here in a very direct way. The C-570-980 order is one of the foundational trade measures governing how Chinese solar cells enter the United States, and the duty rates it produces feed straight into the landed cost of modules. For domestic cell and module manufacturers — the firms building U.S. capacity behind tariff walls and tax credits — a preliminary finding that subsidization continued through 2023 is a finding that the protective rationale for the order still holds. For developers and importers, it is a reminder that the duty exposure on Chinese-origin cells did not go away.
The reason this lands with weight is that solar trade policy now sits on top of an entire domestic-manufacturing build-out. The economics of new U.S. cell and module plants assume that imported, subsidized product carries a duty cost; the CVD order is part of what makes the domestic investment case pencil. A preliminary result that keeps the subsidy finding alive is, in effect, Commerce reaffirming one of the load-bearing assumptions under that build-out — even though, as preliminary results, it sets no final number yet.
What 'preliminary' and 'intent to rescind in part' actually mean
Two pieces of process discipline are essential to reading this correctly. First, these are preliminary results. The subsidy determination is preliminary, the margins are preliminary, and interested parties are explicitly invited to comment — which means the rates can move, sometimes substantially, between now and the final results. Don't trust round numbers, and don't treat a preliminary margin as a settled duty rate. The final results are where the cash-deposit and assessment rates that actually govern entries get fixed.
Second, the intent to rescind in part. Commerce says it intends to rescind the review with respect to the companies listed in Appendix III. In a CVD administrative review, rescission for a company typically means the review is being dropped for that firm — often because the review was withdrawn as to it, or because there were no reviewable entries — so that firm's existing cash-deposit rate carries forward rather than being recalculated in this cycle. It is not a finding that the firm is clean; it is a procedural exit from this particular review. The distinction matters because a casual reader could mistake 'rescind in part' for 'cleared in part,' and they are not the same thing.
The trade-and-deployment tension underneath
This review is a clean illustration of the central tension in U.S. solar policy: the same federal government that subsidizes solar deployment also taxes the cheapest path to deploying it. The countervailing-duty order exists to offset Chinese subsidies and protect domestic producers; the practical effect is to raise the cost of the imported cells that the fastest, cheapest deployment would otherwise use. A preliminary result reaffirming subsidization keeps that wall in place. Whether you read that as protecting a nascent domestic industry or as taxing the energy transition depends on where you sit in the supply chain — but the document is the same for everyone, and it says the order's premise still holds for 2023.
For the firms inside the review, the immediate stake is the comment period. Commerce has invited parties to comment both on the preliminary subsidy determination and on the intent to rescind. That is the window in which a company contests its preliminary margin, argues a subsidy program was wrongly countervailed, or disputes the rescission treatment. The comments shape the record, and the record drives the final results.
What to watch toward the final results
Three things will determine how consequential this review turns out to be. First, whether the preliminary subsidy margins hold or move at the final stage — a margin that drops sharply on review of the comments is a different commercial outcome than one that holds. Second, exactly which firms land in the rescission and which stay in, because that determines whose rates get recalculated this cycle versus whose carry forward. Third, the broader signal: a continued subsidy finding for 2023 reinforces the durability of the China solar CVD regime at a moment when domestic manufacturers are betting capital on that regime staying intact.
The verifiable bottom line is narrow and load-bearing: under order C-570-980, Commerce has preliminarily found that China subsidized solar cells through 2023, and intends to drop the review for some firms. The duty rates that actually move money are still to come at the final results. Read the footnote when Commerce publishes them.
