Federal Government News
Trump Administration Imposes Tariffs and Minimum Import Prices on Polysilicon and Derivatives
President Trump signed a proclamation establishing 15% tariffs and minimum import prices (MIPs) on polysilicon and its derivatives, with measures effective December 4, 2026. These steps follow a Commerce Section 232 report finding that U.S. polysilicon capacity dropped from 50% of global output in 2005 to under 2% in 2024 due to foreign oversupply and trade actions. Under the order, importers must certify compliance with MIPs or face tariffs; incentives are offered for domestic production expansion. The Secretary of Commerce is tasked with monitoring imports and enforcing program compliance, while also coordinating with trading partners implementing similar measures. Provisions allow for modifications if necessary to ensure national security objectives.

White House Fact Sheet: Supply Chain Security for Semiconductors and Solar
A White House fact sheet details the rationale and scope of the new tariffs and MIPs on polysilicon and derivatives, citing national security and supply chain risks amid a sharp drop in U.S. production share. The measures include a 15% tariff on derivative products and create incentives for new domestic investments. The initiative fits into a broader policy framework supporting critical industries like steel and aluminum through tariffs and expanded Section 232 authorities, aiming to rebuild domestic production and reduce reliance on foreign supply for key manufacturing sectors.

Trump Administration Announces Mining and Critical Materials Initiatives Worth Over $2 Billion
The administration unveiled over $2 billion in new mining and processing projects in the U.S., aimed at bolstering the domestic supply chain for critical minerals. Projects announced include $1.4 billion for battery supply chain investment by Sila Nanotechnologies, $150 million for rare earth-free magnet production by Niron Magnetics, and $400 million for scandium value chain development by Sunrise Energy Metals. Additionally, $100 million in new Department of Energy grants is allocated for mining schools, with another $80 million from the Department of War directed to workforce development. Since January 2025, the administration noted approval of roughly $40 billion in mineral sector projects.

Request for Comment: Expanding Section 232 Duties to Additional Derivatives of Aluminum, Steel, and Copper
The Department of Commerce's Bureau of Industry and Security is seeking public comments by August 27, 2026, on a proposal to expand Section 232 tariffs to 14 additional derivative articles of aluminum, steel, and copper. The list includes aluminum powder, weld machine parts, floor safes, conductor cables, fire extinguishers, and filled steel containers for chemical products. The proposal was authorized under Presidential Proclamation 11021, which allows such actions when derivative imports threaten national security or prior policy objectives. Most tariffs would be set at 25%, subject to product-specific exceptions.

DOT Finalizes Rules to Reduce Hazmat Packaging and Special Permit Regulatory Burdens
The Department of Transportation's Pipeline and Hazardous Materials Safety Administration issued several deregulatory final rules effective in August and September 2026. These include: (1) permitting the continued use of packaging authorized under manufacturing special permits for its serviceable life, regardless of the status of the original permit holder; (2) removing the 60-day advance filing requirement for renewing special permits and approvals, allowing renewal applications up until expiration; (3) adoption of DOT Special Permits 21287 and 21379 into regulations to ease ground transport of refrigerating machines containing certain low-flammability refrigerants, including higher mass thresholds for certain gases in compliance with ANSI/ASHRAE norms and the Globally Harmonized System. The actions are presented as compliance cost reductions without altering safety standards.
