President Trump has determined it necessary to impose a <strong>15% ad valorem rate of duty<\/strong> on imports of polysilicon derivatives. This action follows a year-long <strong>Section 232 national security investigation<\/strong> by the Commerce Department aimed at protecting U.S. factories operated by companies like Hemlock Semiconductor and Wacker Chemie (<a href=\"\/stock\/WCH\">WCH<\/a>).<\/p>\n<p>To further stabilize the market, the administration is implementing a <strong>Minimum Import Price (MIP) program<\/strong> effective at <strong>12:01 a.m. ET on December 4, 2026<\/strong>. The program sets specific price floors: <strong>$21 per kilogram<\/strong> for polysilicon, <strong>$100 per kilogram<\/strong> for ingots and wafers, <strong>$0.22 per watt<\/strong> for solar cells, and <strong>$0.38 per watt<\/strong> for solar modules. These measures are designed to prevent foreign competitors from flooding the U.S. market with artificially low-priced materials.<\/p>\n<h2>Export Bans on Critical Minerals and Battery Waste<\/h2>\n<p>In a move to shore up domestic mineral supplies, the Trump administration is blocking the export of <strong>tungsten and battery waste (black mass)<\/strong>. Under a temporary final rule issued via the <strong>Defense Production Act<\/strong>, U.S. persons must allocate <strong>100% of their monthly sales<\/strong> of these materials to domestic buyers starting <strong>August 27, 2026<\/strong>. The restriction aims to ensure that recoverable critical minerals remain available for U.S. defense systems and advanced manufacturing.<\/p>\n<p>The ban on &quot;black mass&quot;\u2014the shredded remains of recycled lithium-ion batteries\u2014is particularly impactful for the burgeoning EV battery recycling sector. Companies like Cirba Solutions and Blue Whale Materials are expected to benefit from the increased domestic availability of these inputs. However, the rule may challenge recyclers who previously relied on high-paying Asian markets for their scrap exports.<\/p>\n<h2>Medline Industries Recalls Neonatal Breathing Circuits<\/h2>\n<p>On the healthcare front, the <strong>FDA<\/strong> confirmed that <strong>Medline Industries, LP<\/strong> initiated a nationwide recall of its <strong>Hudson RCI Neonatal\/Infant Heated Wire Breathing Circuits<\/strong> on July 13, 2026. The recall was prompted by reports of electrical connector failures that resulted in <strong>discoloration, melting, and smoke<\/strong>. While the occurrence rate is low at approximately <strong>0.011%<\/strong>, the potential for thermal damage poses a significant risk to infant patients.<\/p>\n<p>The Neptune humidifier used with these circuits includes safety features to cut power when abnormalities are detected, but the loss of heated wire function can lead to <strong>condensation (rainout)<\/strong> or the delivery of cold, dry gas. These conditions increase the risk of <strong>bronchospasm and respiratory distress<\/strong> in neonates. Medline has advised all healthcare providers to stop using and discard the affected devices immediately.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways The Trump administration has
