## II. Supply-Side Intelligence

1. **Dual Pressure on Raw Material Costs**
The production of DEGMME relies heavily on the catalytic dehydration reaction of ethylene glycol and methanol, deeply binding it to the ethylene–ethylene oxide–ethylene glycol industry chain. In Q1 2026, the average operating rate of global ethylene cracking units dropped to 81.3%. Compounded by delayed restarts of two million-tonne-scale ethylene glycol units in the Middle East due to catalyst replacement, the average spot price of imported ethylene glycol rose to 4,820 CNY/ton, up 12.7% year-on-year. Regarding methanol, affected by the phased rise in domestic coal prices and tightened Iranian export quotas, the mainstream ex-warehouse price in East China reached 2,650 CNY/ton, 9.4% higher than the 2025 average. **The theoretical raw material cost per ton of DEGMME has increased by approximately 1,180 CNY compared to 2025, raising its share of the total cost to 63.5%, indicating that cost support remains solid.**

2. **Production Capacity Landscape and Supply Rigidity**
Jiangsu and Shandong provinces together account for 68.4% of the nation's total production capacity, with further increasing concentration. In Q2 2026, the industry average delivery time extended from 7 days in 2025 to 11 days, strengthening short-term supply rigidity. Meanwhile, the new IEC 63254:2026 standard for electronic-grade solvents tightened the upper limit of aldehyde impurities from 50 ppm to 15 ppm for the first time, forcing leading manufacturers to upgrade their distillation and adsorption processes. This technical upgrade cycle further prolongs delivery times.

3. **Import Contraction**
According to data from the General Administration of Customs, imports of monomethyl ether of ethylene glycol decreased by 13.8% year-on-year from January to May 2026. This is primarily due to production cuts and maintenance at LG Chem's Busan facility in South Korea, which has narrowed the export window and weakened price adjustment capabilities.

## III. Demand-Side Intelligence

1. **Significant Structural Differentiation**
- **High-End Electronic Grade (Purity ≥99.99%)**: With the mass production ramp-up of newly built 8-inch wafer fabs in Hefei and Wuhan, procurement volumes for semiconductor cleaning have increased by 35% month-on-month, with a premium rate of 2.3 times that of standard industrial grade.
- **Coating Solvent Sector**: Production of high-performance water-based coatings for new energy vehicles increased by 28.6% year-on-year, driving a surge in demand for high-end solvents. However, production of traditional oil-based industrial paints decreased by 9.2% year-on-year due to environmental production restrictions.
- **Pesticide Adjuvant Sector**: In 2026, pest and disease outbreaks in major global grain-producing regions were mild, leading to a 5.1% contraction in export orders for plant protection chemicals and a noticeable slowdown in procurement pace.

**Demand exhibits a three-tier differentiation pattern: \"High-end stable, mid-tier under pressure, low-end conceding margin.\"**

2. **Regional Supply-Demand Mismatch**
The electronic manufacturing cluster in South China faces a monthly average shortage of 1,200 tons of electronic-grade products, requiring transport from East China. Coupled with a 17.2% increase in the Yangtze River trunk line container freight index starting April 2026, logistics costs from East to South China have increased by 320 CNY/ton. Conversely, in the North China market, local coating enterprises have operating rates below 65%, and inventory turnover days have extended to 28.6 days (above the industry warning line of 22 days), creating regional inventory accumulation pressure.

## IV. Policy and Environmental Constraints

The Ministry of Ecology and Environment's \"List of Key Controlled New Pollutants (2026 Edition),\" implemented in March 2026, listed ethylene glycol monomethyl ether as an environmental risk attention substance. It requires production enterprises to establish a full lifecycle traceability system and to execute direct transmission of VOCs emission online monitoring data starting October 2026. According to calculations by the China Chemical Environmental Protection Association, compliance upgrades increase the annual compliance cost by 4.2 million CNY per 50,000-tonne production unit. **The rigid rise in environmental compliance costs is reshaping the cost floor on the supply side of the industry.**

## V. Correlated Product Linkages

| Product | Sept 2026 Avg Price | Oct 9, 2026 | Trend |
|---|---|---|---|
| Methanol | 3,392 CNY/ton | 4,042 CNY/ton | ↑ Rapid Surge |
| Acetic Acid | 3,997 CNY/ton | 4,691 CNY/ton | ↑ Following Methanol |
| Ethylene Glycol | 6,915 CNY/ton | 6,124 CNY/ton | ↓ Weakening due to Inventory Buildup |

The fundamental supply and demand situation for ethylene glycol has shifted from a tight balance to a loosening inflection point—port inventory has rapidly rebounded from a five-year low of 110,000 tons to 180,000 tons. The combination of new capacity coming online in Q4 and seasonal inventory buildup suggests that the low inventory levels and geopolitical premiums that previously supported prices may simultaneously \"fade.\" **The price softening of ethylene glycol, an upstream raw material, exerts a certain drag on the cost side of DEGMME.**

## VI. Analytical Judgment and Forecast

**Short-term (1-2 weeks): Horizontal Oscillation, 11,500 CNY/ton as Key Support**
The consistent locking of quotes at 11,500 CNY/ton in the Shandong region for multiple days indicates a temporary equilibrium between sellers' willingness to support prices and buyers' pressure to lower them. High-level methanol prices provide bottom support, but the decline in ethylene glycol prices weakens cost push. Prices are expected to fluctuate narrowly in the range of 11,200–11,800 CNY/ton.

**Medium-term (1-3 months): Structural Upside Possible, but Differentiation Will Intensify**
- **Electronic-grade products**: Benefiting from semiconductor capacity release and quality upgrades driven by new standards, prices are expected to continue rising, with potential for further expansion of the premium.
- **Industrial-grade products**: Inventory accumulation pressure in North China and weak demand from traditional coatings will continue to suppress mid-to-low-end prices. However, environmental compliance costs provide a floor, limiting the potential for significant declines.
- **Regional price spreads**: High logistics costs between East and South China will maintain regional price spreads. The high quote of 18,000 CNY/ton in Zhejiang reflects the structural premium of electronic-grade products, not a general market trend.

**Risk Warnings**
1. If the blockade of the Strait of Hormuz continues to escalate, the upward shift in the crude oil price center will further push up costs across the entire ethylene–ethylene glycol–methanol chain.
2. If the concentrated commissioning of new ethylene glycol capacity in Q4 exceeds expectations, cost support on the raw material side may be weakened.
3. If the enforcement intensity of environmental policies exceeds expectations, the clearing of small and medium-sized production capacity will accelerate industry concentration, enhancing the bargaining power of leading enterprises.

**Comprehensive Assessment: The DEGMME market is currently in a period of triple-gameplay involving \"cost support, demand differentiation, and policy pressure.\" The short term is characterized by stability, while the medium-to-long term shows a deterministic growth logic in the high-end electronic-grade segment, whereas standard industrial-grade products face a mildly pressured landscape.**
