Today's supply chain and manufacturing highlights for June 28, 2026, with summaries, links, and brief commentary.
I. Semiconductors & Critical Materials
1. Japan's Two WF6 Producers Permanently Exit on July 1 — ~25% of Global Capacity Gone in Three Days
Summary:
Per Korean Tech Texas on June 26, Kanto Denka Kogyo and Central Glass have formally notified Samsung, SK hynix, and TSMC that June 30 is their last WF6 shipment date and they will permanently exit the semiconductor gas business on July 1. Combined annual capacity of roughly 2,100 metric tons represents about 25% of a global market estimated at 8,000–9,000 t/yr; the root cause is China's tightened tungsten powder exports, cutting off high-purity feedstock that accounts for 60–70% of WF6 cost. Korea's SK Specialty (2,000 t/yr) and Foosung (900 t/yr) are the main alternatives but have notified customers of 70–90% price hikes for H2 2026; some foundries are compressing qualification cycles that normally exceed 18 months. The Elec, updated June 28, notes WF6 poses a more immediate risk than helium because ~80% of tungsten powder comes from China; Samsung is more exposed than SK hynix due to heavier Japanese reliance. Samsung Taylor's 2nm ramp faces the same gap — no U.S. WF6 source and Korean capacity prioritized for domestic fabs under a "commanded demand" dynamic.

Commentary:
Tungsten export controls have escalated from input inflation to permanent Japanese capacity removal — July 1 is a hard deadline for specialty gas supply, not a negotiable buffer.
2. Korea Semiconductor-Grade CO₂ Inventory Falls Below One-Month Safety Line
Summary:
Per Critini Research analyst Jukan, citing industry sources via BlockBeats on June 28, procurement of high-purity CO₂ for advanced semiconductor processes has triggered a warning signal. The issue is not demand but a sharp drop in CO₂ by-product output as refinery and petrochemical operating rates decline; manufacturers typically hold about two weeks of inventory (~one month of usage), but industry consensus is that stocks have fallen below that threshold. Samsung Electronics consumes roughly 1,800–2,000 tons/month of high-purity CO₂; SK hynix about 600–700 tons/month. Production has not been interrupted, but buffers are shrinking and procurement has intensified — even with price increases, additional supply is hard to secure short term. Liquefied CO₂ prices are up roughly 20% since the start of the year; tight conditions may persist through year-end. Major Korean suppliers include Taekyung Chemical, Sundo Chemical, Dongkwang Chemical, and SK Air Plus.

Commentary:
WF6 and CO₂ alerts landing the same day show Korean fabs facing a compound specialty-gas squeeze — by-product gas fragility rivals strategic-mineral risk.
3. Micron Q3 Revenue $41.46B, 16 Strategic Customer Deals Boost Samsung and SK hynix Q2 Outlook
Summary:
Per The Korea Times on June 28 (Sunday), Micron's fiscal Q3 results announced last week — revenue of $41.46 billion, up 345.7% YoY — are lifting expectations for Samsung Electronics and SK hynix Q2 profitability. Micron secured 16 "Strategic Customer Agreements" guaranteeing approximately $100 billion in minimum cumulative revenue through 2030, with 3–5 year contracts spanning data center, consumer, and automotive segments; the company said this would "fundamentally transform" its business model. Historically, memory supply agreements were customer-led with quarter- or half-year terms; amid severe supply-demand imbalance, supplier leverage is rising, and Samsung and SK hynix are expanding mid- to long-term volume commitments. FnGuide consensus forecasts Samsung Q2 operating profit of 86 trillion won and SK hynix 63.45 trillion won, both potentially record-breaking; Samsung guidance is expected around July 7, SK hynix results in late July.

Commentary:
Memory is shifting from a cyclical commodity to a long-contract strategic asset — supply bottlenecks are returning HBM/DRAM allocation power to the fabs.
4. China Critical Metal Imports Up ~60% Jan–May While Export Controls Stay in Place
Summary:
Per Nikkei Asia analysis of trade data on June 27, China is amassing critical metal supplies while maintaining export restrictions on tungsten and related materials. Imports of key metals rose roughly 60% YoY in January–May 2026, including tungsten ore from North Korea and Myanmar among friendly sources; Beijing is locking upstream supply even as it tightens tungsten powder exports to Japan, pushing global APT benchmark prices up 557% since February 2025 (Bloomberg). The strategy directly overlaps with Japan's permanent WF6 exit timeline and is forcing increased U.S. tungsten scrap exports to Japan. Analysts say China is strengthening upstream control via simultaneous "export throttling + import hoarding" — a hallmark of weaponized supply chains.

Commentary:
Critical-minerals competition is now about who stockpiles and who can choke — import surges alongside export controls define supply-chain weaponization.
II. Capacity & Relocation
5. TSMC 28nm Monthly Input Falls from 200K to 150K Wafers; UMC and VIS Gain Mature-Node Room
Summary:
Per SemiMedia on June 23, citing supply chain sources, TSMC is significantly reducing 28nm capacity to redirect resources toward advanced nodes and advanced packaging. Monthly wafer input at Fab 15A has reportedly fallen from about 200,000 at the start of the year to roughly 150,000 in June, with 28nm output down more than 25% YTD. Analysts say this reflects a shift from lower-margin mature nodes toward AI, HPC, and high-value packaging; yet display drivers, networking, automotive, and industrial chips still depend heavily on 28nm/22nm. TSMC's retreat may create room for UMC, VIS, and other mature-node foundries. Longer term, competition between TSMC and Samsung on 2nm, A14, and advanced packaging will intensify — a dual-track foundry market of advanced-node rivalry plus mature-node redistribution.
Links:
Commentary:
TSMC's "exit mature, chase advanced" move is reshaping the second-tier foundry order book — for auto and industrial customers, switching fabs is more realistic than chasing leading-edge slots.
6. India Semiconductor Mission Approves 12 Projects with Rs 1.64 Lakh Crore Pipeline
Summary:
Per India's official fact sheet and NewKerala, the India Semiconductor Mission has approved 12 manufacturing projects with an investment pipeline of approximately Rs 1.64 lakh crore, comprising one fab, two compound-semiconductor fabs, and nine packaging units. India Semiconductor Mission 2.0, announced in the Union Budget 2026–27, deepens focus on equipment, materials, indigenous IP, and resilient supply chains; the IndiaAI Mission (Rs 10,372 crore budget) has established a shared compute facility with 45,000 GPUs. Electronics has grown into a Rs 13 lakh crore industry — India's third-largest export category. However, West Asia conflict-driven specialty gas and logistics bottlenecks may still delay projects such as Tata's Dholera fab (see June 27 coverage).

Commentary:
India's "policy approval" and "fab ramp" remain separated by specialty gases, chemicals, and geopolitical logistics — three hard constraints.
III. Policy & Geopolitics
7. China May Industrial Profit Growth Slows to 21.1%; AI and Metals Support Masks Weak Domestic Demand
Summary:
Per IANS on June 28, NBS data show industrial profits rose 21.1% YoY in May, easing from 24.7% in April — the first slowdown in six months; January–May cumulative growth was 18.8%, slightly below the 19% consensus. AI-driven electronics and rising copper/aluminum prices (partly from Middle East energy disruptions) remain key supports: raw materials contributed 10.2 percentage points, high-tech manufacturing 8 points, equipment manufacturing 5.2 points. But NBS statistician Yu Weining said "strong supply and weak demand within the country remained outstanding"; analysts note sluggish investment and cautious consumption limit recovery strength. Total industrial profits reached 3.14 trillion yuan in January–May, still below the 2022 comparable level.

- Xinhua — AI, new-energy demand drive China's industrial profit growth (June 27, 2026)
Commentary:
Chinese manufacturing walks a tightrope between export/AI upstream strength and weak domestic demand — profits look strong, but totals haven't recovered to 2022 peaks.
8. USTR Proposes Section 301 Forced-Labor Tariffs: Comments Due July 6, Covering 99.4% of U.S. Imports
Summary:
Per Elliott Davis mid-2026 trade analysis, on June 2 USTR proposed additional 10% or 12.5% ad valorem duties on virtually all imports from 59 countries plus the EU (99.4% of U.S. imports) following 60 Section 301 investigations on forced-labor enforcement failures. Comments are due July 6, with hearings from July 7. Meanwhile, the temporary 10% global Section 122 surcharge expires statutorily on July 24; a June 3 Executive Order also tightens Importer-of-Record eligibility, bonding, and disclosure. Importers are advised to model tariff stacks by HTS classification, verify Section 232 metal origin rules, and track IEEPA refund eligibility via the CAPE tool.

Commentary:
The tariff framework is shifting from IEEPA "emergency" to institutionalized 301/232 — two July deadlines will set Q3 landed-cost models.
9. U.S. Proposes AI Partnership With EU to Build Semiconductor and Critical-Minerals Supply Alliance
Summary:
Per Bloomberg on June 25, the U.S. has proposed that the EU join an artificial intelligence partnership as part of an effort to form a semiconductor supply-chain alliance amid intensifying competition with China. A draft statement seen by Bloomberg reads: "Recognizing the critical importance of the physical backbone for artificial intelligence — from critical minerals and energy to computer and semiconductor manufacturing — we share the view that the future of AI should be built on a foundation of trusted collaboration, economic security, innovation, and fair competition." The move aligns with G7 critical-minerals initiatives and transatlantic CHIPS/IPCEI policies, extending alliance-building from regulation to upstream capacity and materials security.

Commentary:
Chip supply-chain bloc formation is moving from export-control lists to institutional transatlantic alliances — but WF6 and tungsten bottlenecks show agreements don't equal materials on the ground.
IV. Logistics & Trade
10. Hormuz "Half Open, Half Closed": Windward Counts Only 12 Transits on June 28 as MOU Recovery Stalls Within 24 Hours
Summary:
Per Gulf News, last updated June 28 at 04:06, the Strait of Hormuz remains technically open but commercial confidence is far from restored. After Iran's June 25 drone strike on Evergreen's Ever Lovely, the June 28 attack on Panama-flagged tanker MT Kiku (carrying over 2 million barrels of crude) pushed the June 17 U.S.–Iran MOU's 60-day free-passage pledge toward collapse. Windward data show only 12 commercial vessels transited on Sunday, June 28, down from 21 on Saturday; European and neutral flag vessels were largely absent, with 5 of 8 inbound ships running "dark" without AIS. Chubb CEO Evan Greenberg described the Gulf as a "war zone environment" with only a narrow channel in use; BIMCO's Jakob Larsen said owners need defined safe routes, escorts, and emergency protocols before normalizing traffic. The IMO has suspended its voluntary vessel movement and evacuation framework in the area.

- The Statesman — Two tankers in three days: shipping attacks strain US-Iran ceasefire
Commentary:
"Strait not blocked" and "supply chain unusable" have split again — 12 ships/day cannot sustain normal flows for ~20% of global petroleum liquids trade.
11. UKMTO Raises Hormuz Threat Level to "Substantial"
Summary:
Per Fox News live updates on June 27–28, the UK Maritime Trade Operations Centre raised the Strait of Hormuz threat level from moderate to substantial after consecutive merchant-vessel attacks, prompting tighter risk assessments from owners and insurers. U.S. forces conducted retaliatory strikes on Iranian military targets following June 25–28 tanker incidents; CENTCOM said 55 merchant ships still transited on Saturday, moving over 17 million barrels of oil, but independent shipping data cited by Windward and Gulf News paint a more cautious picture of low traffic and high "dark" sailing. Maersk had earlier warned incremental Hormuz-related costs exceed $500 million/month, with 15–20% freight increases potentially passing to consumers.
