## Recent Market Dynamics, Analysis, and Forecast for Diethyl Carbonate (DEC)

## I. Market Dynamics Intelligence

### (1) Price Trends
- **Benchmark Price**: According to data from Inchems, the benchmark price of DEC on July 28, 2026, was 8,700.00 RMB/ton, remaining flat compared to the beginning of the month and standing at an annual high. Over the past year, the minimum price was 8,380.00 RMB/ton, the maximum was 8,775.00 RMB/ton, the median was 8,577.5 RMB/ton, the top deviation was -75 RMB/ton, the bottom deviation was 320 RMB/ton, and the average was 8,569.91 RMB/ton.
- **Market Quotations**: There is significant variation in quotations among different manufacturers. Suzhou Senfeida Chemical Co., Ltd. quotes 14,000 RMB/ton for DEC with 99.8% purity. Shandong Yeyang Chemical Co., Ltd. quotes a range of 7,800–8,000 RMB/ton. Several manufacturers, including Shandong Junfeng New Material Co., Ltd., Aite (Zhejiang) Supply Chain Management Co., Ltd., and Wuhan Hengjiu Chemical Co., Ltd., mostly quote around 9,000 RMB/ton. Shandong Hongyang Chemical Co., Ltd. quotes 7,100 RMB/ton for its 99.9% pure product, representing a relatively low level among recent quotations.

### (2) Market Supply and Demand
- **Supply Side**: Multiple manufacturers participate in market supply. Differences in capacity and product quality among manufacturers lead to divergent market quotations. Some manufacturers offer products with varying purities and packaging specifications; for example, Shandong Yeyang Chemical Co., Ltd. offers 99.9% purity DEC in 190kg/barrel packaging.
- **Demand Side**: From an industry perspective, DEC is primarily applied in the field of lithium-ion battery electrolytes, accounting for approximately 84.28% of its share. With the promotion of new energy vehicles (NEVs), the demand for lithium-ion battery electrolytes continues to rise. Applications in digital batteries are diversifying, and the energy storage battery market is gradually expanding, providing support for DEC demand. However, recent market dynamics do not clearly reflect significant changes on the demand side.

## II. Analysis and Judgment

### (1) Reasons for Price Stability
- **Supply-Demand Balance**: The current market supply and demand relationship remains relatively stable, without obvious signs of shortage or oversupply, contributing to price stability in July with the benchmark price matching the beginning-of-month level.
- **Cost Factors**: Although cost changes are not explicitly mentioned, it is speculated that raw material prices and production costs are relatively stable at this stage, exerting no significant driving or suppressing effect on DEC prices.

### (2) Reasons for Quotation Differences
- **Product Quality**: Differences in DEC purity among manufacturers affect prices; higher purity generally correlates with better product quality and higher prices. For instance, the quotation of 14,000 RMB/ton for 99.8% purity DEC from Suzhou Senfeida Chemical Co., Ltd. is significantly higher than the 7,100 RMB/ton quote for 99.9% purity DEC from Shandong Hongyang Chemical Co., Ltd., which may be related to factors such as production processes and product quality stability.
- **Brand and Region**: Brand reputation and regional factors also contribute to price differences. Manufacturers with well-known brands or those located in economically developed areas with strong market demand may command higher prices. Conversely, smaller manufacturers or those in highly competitive regions may lower prices to capture market share.

## III. Forecast

### (1) Short-term (1–2 Months)
- **Price Trend**: DEC prices are expected to remain stable in the short term. Given the balanced supply and demand and the absence of significant cost fluctuations or policy impacts, the likelihood of sharp price increases or decreases is low.
- **Market Supply and Demand**: On the supply side, manufacturers will maintain normal production operations, with no significant changes in market supply. On the demand side, the development trends in industries such as NEVs, digital batteries, and energy storage batteries remain relatively stable, supporting steady DEC demand.

### (2) Long-term (6 Months–1 Year)
- **Price Trend**: If the NEV market continues to develop rapidly, leading to a substantial increase in lithium-ion battery electrolyte demand, this could drive up DEC demand and potentially push prices higher. Conversely, if NEV market development falls short of expectations, or if new substitute products emerge, demand may decline, leading to price drops.
- **Market Supply and Demand**: On the supply side, changes in market demand may prompt new entrants or capacity expansions by existing manufacturers, thereby altering the supply landscape. On the demand side, trends will primarily depend on downstream industry developments, such as NEV sales volumes, the pace of digital product upgrades, and the promotion of energy storage battery markets.
