PHOENIX, AZ, UNITED STATES, August 18, 2026 /EINPresswire.com/ — Graphene & Solar Technologies Limited (OTCID: GSTX) (“GSTX”) welcomes the White House’s proclamation August 6 under Section 232 of the Trade Expansion Act of 1962, “Adjusting Imports of Polysilicon and its Derivatives into the United States.” It introduces minimum import prices for polysilicon and derivative products and imposes a 15 percent tariff on certain derivatives.

“This is a significant step forward for domestic solar manufacturing,” said Jason May, executive chairman and CEO of GSTX. “The Section 232 proclamation reinforces the national priority of rebuilding American manufacturing capacity and strengthening the American solar supply-chain.”

May continued, “This proclamation provides strong underpinning of the business case for GSTX’s planned domestic wafer manufacturing strategy. It reinforces the compelling need in the market for American-made solar products and materials.”

GSTX’s wholly owned U.S. subsidiary, The Quartz & Silicon Materials Company (“QSM USA”), is developing a silicon wafer manufacturing facility in Southern California. The factory is being established in an existing industrial facility, designed to reach annual wafer production capacity of 10 GW when fully operational. QSM USA is targeting first production in early 2027 and is advancing commercial sales discussions.

QSM USA was recently awarded a $45 million California Competes Tax Credit over five years in support of its California silicon wafer manufacturing projects. QSM USA has also started filling its order book; 3GW of production has been allocated. These milestones are consistent with GSTX’s broader strategy of developing a global network of vertically integrated manufacturing subsidiaries operating under the QSM brand to develop Western supply chains that span high-purity quartz, silicon, polysilicon, and silicon wafers.
