Memory Makers Brace for Hydrogen Fluoride Pricing Shock as Hormuz Blockade Impacts Supply Chain — Key Etching and Cleaning Material Faces Sharp Cost Increase Amid Trade Disruption

Why It Matters

The cost spike threatens to raise memory and storage prices amid a global chip shortage, underscoring the geopolitical fragility of semiconductor material supplies. It also forces the industry to accelerate domestic production and diversify sources.

Key Takeaways

• China’s HF price up 130% since early 2026
• South Korean chip makers face cost pass‑through by July
• 2023 Japan‑Korea HF dispute cut 87.9% supply, but price impact minimal
• Fluoride Korea’s $100M plant aims for 50,000‑ton capacity by Q4 2026
• Sulfuric acid cost jumped 27% week‑on‑week, driving HF price surge

Pulse Analysis

The closure of the Strait of Hormuz after the February 2024 conflict in Iran has sent shockwaves through the just‑in‑time supply chains that power today’s semiconductor fabs. Anhydrous hydrogen fluoride (HF), a critical etchant used to strip oxide layers from silicon wafers, is produced from fluorite and sulfuric acid, the latter derived from sulfur—a by‑product of oil and natural‑gas refining. With Iranian oil shipments curtailed, sulfur output has slipped, tightening the raw‑material base for HF. The ripple effect is now visible in China, where export restrictions and a mining accident have pushed HF prices up 130 % from early‑2026 levels.

The price surge translates directly into higher manufacturing costs for South Korea’s memory giants Samsung and SK Hynix. Local chemical firms such as Soulbrain, ENF Technology and Foosung have already received HF orders at the new rates and expect to pass the expense to chipmakers by early July. In 2019, a Japan‑South Korea trade spat cut 87.9 % of HF imports, yet abundant memory inventories muted any consumer‑price impact. This time, however, the market is already tight, with inventory buffers exhausted, raising the likelihood that end‑users will see steeper DRAM and NAND prices.

To blunt future shocks, South Korea is betting on domestic production. Fluoride Korea, a BGF EcoMaterials subsidiary, is pouring roughly $100 million into a 50,000‑ton per year HF plant slated for Q4 2026, enough to satisfy about half of national demand. Japan is also scouting alternative sources, signaling a broader regional shift away from China‑centric chemical supply chains. While the new facility will not resolve the immediate July cost pass‑through, it offers a strategic hedge that could stabilize HF pricing and, by extension, memory‑chip margins in the years ahead.
