Wet Electronic Chemicals Wholesale: Procurement Strategy Amid Semiconductor Price Surge (2026)

Wet Electronic Chemicals: The “Blood” of Semiconductor Manufacturing

Wet electronic chemicals are critical process materials in semiconductor, display panel, and photovoltaic manufacturing, encompassing high-purity reagents (sulfuric acid, hydrochloric acid, hydrofluoric acid, hydrogen peroxide, etc.) and functional chemicals (developer, stripper, cleaning solution, etc.). In 2026, driven by the strong recovery of the semiconductor industry, wet electronic chemicals wholesale demand growth has reached 63.73%, making annual framework agreements the core procurement strategy.

Wet Electronic Chemicals Classification and Purity Grades

• SEM G1-G2 Grade (99.999% purity): Suitable for solar photovoltaic, mid-to-low-end display panels
• SEM G3-G4 Grade (99.9999%-99.99999% purity): Suitable for high-end display panels, mature process chips
• SEM G5 Grade (10ppt-level metal impurities): Suitable for advanced process (28nm and below) chips
• Ultra-High Purity Grade (below ppt level): For 7nm and below advanced processes, only a few global suppliers can meet the standard

2026 Market Supply-Demand Analysis

The wet electronic chemicals market is experiencing unprecedented supply-demand tightness:

1. Demand Explosion: Semiconductor capacity expansion + AI chip demand surge, driving high-purity reagent demand growth of 63.73%
2. Supply Tightness: Global capacity for G5 grade and above wet electronic chemicals is insufficient, delivery cycles extended from 4 weeks to 8-12 weeks
3. Price Uptrend: Hydrofluoric acid up 15-20% YoY, high-purity sulfuric acid up 10-15%, functional chemicals with even larger increases
4. Domestic Substitution Accelerating: Domestic G4 grade and below has achieved large-scale substitution, G5 grade is in the breakthrough verification stage

Core Product Price Trends

• High-Purity Sulfuric Acid (G5 Grade): 18-25 RMB/kg, up 12% from 2025
• High-Purity Hydrofluoric Acid (G4 Grade): 35-50 RMB/kg, supply tightness driving 20% increase
• Positive Photoresist Stripper: 80-120 RMB/kg, significant functional chemical premium
• Developer (TMAH 2.38%): 25-40 RMB/kg, intense domestic substitution competition

Wholesale Procurement Key Points

When selecting wet electronic chemicals wholesale suppliers, it is recommended to focus on the following evaluation dimensions:

• Purity Guarantee: Whether equipped with ppt-level metal impurity detection capability (ICP-MS)
• Batch Stability: Whether key indicator fluctuations are controlled within ±2%
• Packaging and Storage/Transport: Whether providing 1L-200L full specification packaging, whether hazardous chemicals transport qualifications are complete
• Technical Service: Whether providing process optimization support, anomaly analysis, on-site service
• Capacity Scale: Whether annual capacity reaches 10,000-ton level, whether able to meet bulk procurement needs

Procurement Strategy and Price Locking Recommendations

Facing the price surge, the following strategies are recommended:

1. Annual Framework Agreements: Sign 1-2 year framework agreements with core suppliers to lock prices and supply volumes, avoiding price fluctuation risks
2. Multi-Source Supply System: Establish 2-3 qualified suppliers, domestic + import combination, ensuring supply security
3. Safety Stock Management: Maintain 4-8 weeks safety stock for critical products, preventing supply disruption from affecting production
4. Cost Optimization Combination: Mature processes prioritize domestic G4 grade products (40-60% lower cost), advanced processes maintain imported G5 grade supply

Market Trend Outlook

• AI chip and HBM memory capacity expansion will continue to drive high-purity wet electronic chemicals demand
• Domestic 12-inch wafer fab concentrated production will drive G5 grade product domestic substitution rate from 15% to 30%
• Under green manufacturing trends, waste liquid recovery and regeneration technology will become a new path for cost reduction
• Functional chemicals (CMP slurry, cleaning solution) growth rate will exceed bulk high-purity reagents

For semiconductor and display panel manufacturers, now is the critical window period for wet electronic chemicals procurement. It is recommended to sign annual framework agreements as soon as possible to lock prices and capacity, while accelerating domestic substitution verification to build a secure, efficient, and competitive supply system.
