## I. Market Quotation Dynamics Overview

1. Benchmark Quotation Data

| Time Node | Quotation Source | Specification/Origin | Quotation (CNY/ton) | Remarks |
|---|---|---|---|---|
| 2026-09-23 | SunSirs / Jiangsu Xile Energy | Purity >99%, Domestic, Jiangsu | **22,700** | Benchmark quotation for bulk commodities |
| 2026-10-30 | GuideChem / Guangzhou Shanghe Chemical | Purity 99%, Industrial Grade, Guangzhou, Guangdong | **23,000~28,000** | Small batch: 28 CNY/kg (≥180kg); Large batch: 23 CNY/kg (≥1080kg) |

2. Price Monitoring Frequency

From early September 2026 to November 10, SunSirs has **published daily** commodity quotation updates for diethylformamide, covering approximately 70 trading days from September 1 to November 10. This high monitoring density indicates active market attention and the need for continuous tracking of price fluctuations.

3. Pricing Mechanism

SunSirs employs a formula-based pricing system:

> **Settlement Price = SunSirs Benchmark Price × K + C**
> - K: Adjustment coefficient (including credit period costs, etc.)
> - C: Premium/Discount (including logistics costs, brand price differentials, regional price differentials, etc.)

## II. Market Dynamics Analysis

1. Price Trend Assessment

- The **benchmark price of 22,700 CNY/ton in late September** serves as a clear, traceable anchor for recent bulk quotations;
- By **late October, small-batch retail prices had risen to 28,000 CNY/ton**, representing an increase of approximately **23.3%** compared to the September benchmark price, while large-batch procurement prices at 23,000 CNY/ton saw only a marginal 1.3% increase;
- The significant expansion of the price gap (5,000 CNY/ton) reflects **tight supply and demand in the small-lot, spot market**, whereas large-lot, long-term contract customers still retain room for price negotiation.

2. Supply and Demand Landscape Assessment

- **Supply Side**: Major domestic manufacturers, such as Jiangsu Xile Energy, continue to provide stable quotations with consistent production capacity, but no signals of new capacity expansion have been observed;
- **Demand Side**: As an excellent polar solvent, diethylformamide is widely used in synthetic fibers, polyurethane spinning, polymer films, coatings, and the pharmaceutical sector, providing strong support from downstream rigid demand;
- **Regional Divergence**: Quotations in Guangdong (Guangzhou Shanghe Chemical) are notably higher than those at the production hub in Jiangsu, with logistics costs and regional supply-demand imbalances in South China being the primary drivers.

3. Risk Factors

- Fluctuations in raw material prices (diethylamine, formic acid/formate esters, etc.) will be directly transmitted to the final product price;
- Stricter environmental regulations may compress production capacity of small and medium-sized enterprises, thereby increasing industry concentration;
- Winter transportation restrictions in northern regions are likely to increase logistics costs, leading to an upward adjustment in the C value.

## III. Forecasts and Recommendations

| Dimension | Assessment |
|---|---|
| **Short-term (Mid-to-Late November)** | Prices are likely to remain at high levels with fluctuations. The spot market has support around 28,000 CNY/ton, while the bulk benchmark price may slightly rise into the 23,000~24,000 CNY/ton range. |
| **Medium-term (December 2026 ~ Q1 2027)** | If raw material costs stabilize, prices will likely return to the reasonable range of 22,000~24,000 CNY/ton. If environmental production restrictions are tightened, prices may break through 25,000 CNY/ton. |
| **Operational Recommendations** | For bulk procurement, it is advisable to lock in long-term contracts and the K value. For spot procurement, consider building positions in batches during price pullbacks. Closely monitor daily benchmark price changes from SunSirs and trends in raw material diethylamine. |
