The USITC instituted Investigation No. 337-TA-1506 on June 15, 2026, targeting 3D NAND and HBM DRAM memory chips and products containing them. Texas-based MonolithIC 3D filed the complaint against KIOXIA (Japan and Taiwan) and SK hynix (South Korea), alleging infringement of five U.S. patents. Why it matters: KIOXIA and SK hynix together supply a significant share of global 3D NAND flash and DRAM. If the ITC issues exclusion orders, imports of NAND flash, DRAM modules, SSDs, and any products containing those chips from either company would be blocked at U.S. ports — affecting electronics manufacturers, data-center operators, and component distributors. USITC opens Section 337 on rack-scale GPU and DPU systems — NVIDIA, Microsoft, and AWS named https://tariffnotices.com/signal/usitc-gpu-dpu-337-ta-1505/ https://tariffnotices.com/signal/usitc-gpu-dpu-337-ta-1505/ Sun, 12 Jul 2026 13:53:04 GMT Import Enforcement Verified brief. The USITC instituted Investigation No. 337-TA-1505 on June 9, 2026, targeting rack-scale GPU computing systems and DPU technologies. Texas-based Xockets filed the complaint against NVIDIA, Microsoft, Amazon/AWS, and Annapurna Labs, alleging infringement across five patents. Why it matters: If the ITC issues a limited exclusion order, companies importing rack-scale GPU systems with programmable hardware acceleration fabrics would be blocked at U.S. ports. Importers relying on AI compute infrastructure should watch the investigation timeline. USITC enters remedy phase in LCD glass substrate case — exclusion order on Chinese imports possible https://tariffnotices.com/signal/lcd-glass-substrate-337-ta-1441/ https://tariffnotices.com/signal/lcd-glass-substrate-337-ta-1441/ Sat, 11 Jul 2026 14:05:56 GMT Import Enforcement Verified brief. The USITC voted on June 8, 2026, to partially review an ALJ's Section 337 violation finding in Investigation No. 337-TA-1441. Corning filed the complaint against Caihong/Irico, CSOT, CHOT, and TCL, and the case remains in the Commission's remedy phase. Why it matters: If the Commission issues a limited exclusion order, LCD glass substrate products — and finished display products containing them — from the four remaining respondents would be blocked at U.S. ports. The remedy decision affects supply chains for TVs, monitors, and other LCD end-products.
