Trump orders trade talks, not new tariffs, after Section 232 wind turbine probe

President Donald Trump signed a proclamation following a Section 232 investigation, launched by the Commerce Department in August 2025, into imports of wind turbines and their components, directing Commerce Secretary Howard Lutnick and U.S. Trade Representative Jamieson Greer to open or continue negotiations with trading partners and report on progress within 180 days. The proclamation states the U.S. is reliant on wind turbine and part imports and that foreign-made turbines and parts present unique cybersecurity risks, citing inverters in particular.

Report: US polysilicon minimum import price increase may slip past Dec. 4

Industry checks reported by pv magazine indicate that an increase in US minimum import prices under the polysilicon Section 232 framework may not occur until after Dec. 4, with implementation potentially moving into early 2027, reflecting Commerce's desire to observe how the initial proclamation operates and to gather further investor feedback. The report says Commerce and CBP are expected to scrutinize imports declared at the minimum price, and shipments may be detained while the underlying transaction is verified.

pv magazine USA commentary: U.S. project requirements are shaping sodium-ion battery specifications

In a pv magazine USA commentary, ESS Inc. Chief Commercial Officer Randy Selesky writes that domestic content thresholds, foreign-entity-of-concern restrictions and Executive Order 14421 are driving U.S. developers to trace cell origin, cathode and anode material sourcing, cell finishing and system integration locations, and corporate ownership across the supply chain. He says sodium-ion has a structural advantage because it avoids concentrated lithium, nickel, cobalt and manganese supply chains, and that UL 9540A test data at the cell, module, unit and installation levels drives deflagration venting, suppression sizing, setbacks and fire service response plans.

Energy Vault tracks implementation of Trump executive order restricting foreign-made bulk power components

Energy Vault Chief Revenue Officer Marco Terruzzin told Utility Dive that the energy storage company is closely following implementation of President Donald Trump's recent executive order restricting the use of foreign-made bulk power components and is assessing its impacts on a project-by-project basis as it diversifies its supply chain. The company said last week it would acquire a 2.3-GW development portfolio from Goshe Energy Storage, including 350 MW of ready-to-build capacity that could come online in early 2028, and secured up to $40 million in credit from S2G Investments to back development, construction and operation of that portfolio.

BIS issues temporary final rule on polysilicon stockpiling under Proclamation 11052

BIS issued a temporary final rule, effective September 22, 2026 through December 3, 2026, setting the criteria and process it will use to monitor existing companies for evidence of stockpiling polysilicon and polysilicon derivatives ahead of import adjustments effective December 4, 2026 under Proclamation 11052. The rule limits a newly established importer's ability to stockpile, imposes import limitations on new importers that register with CBP on or after August 6, 2026, and subjects companies found to be stockpiling to an import prohibition if necessary. It also establishes the process for such companies to obtain a waiver from any import prohibitions imposed under the rule.
