- On April 11, Wencheng Chemical (Yixing, Jiangsu) maintained its 99.5% purity quotation at RMB 7,200/ton, and Laya Chemical (Shandong) held its 99% purity quotation at RMB 8,700/ton.
- As of mid-May 2026, phenol prices have risen from a bottom of approximately RMB 5,675/ton to around RMB 7,700/ton. Concurrently, Changqing Technology’s AMS sales price (tax-inclusive) rebounded to approximately RMB 11,500/ton.

2. Regional Price Disparities:
- The market price for 99% purity AMS in Zibo, Shandong Province remains stable at RMB 8,700/ton.
- Suzhou Senfeida Chemical (Jiangsu Province) posted significantly higher-than-average quotations: on March 11, its ex-factory price for 99.5% purity AMS reached RMB 14,500/ton, and for 99% purity, RMB 13,200/ton.
- Aite (Zhejiang) Supply Chain Management Co., Ltd. quoted RMB 9,500/ton on March 12 for GB-standard 99% purity AMS.
- Hunan Jinyu Fine Chemical Co., Ltd. quoted RMB 11,000/ton (99.5% purity) on March 10.

3. Purity-Based Price Differential:
- Higher-purity (99.5%) products generally command premium pricing—typically above RMB 10,000/ton—whereas lower-purity (99%) products are mostly priced below RMB 9,500/ton.

II. Supply-Demand Dynamics

1. Supply Situation:
- China’s AMS production capacity is unevenly distributed across regions, resulting in disparities in regional output capacity and number of producers. Total effective domestic capacity stands at approximately 86,000 tons/year, with Shandong Yuhuang Chemical, Jiangsu Yangnong Chemical, and Zhejiang Huangma Chemical collectively accounting for 68.4% of national total capacity.
- Actual output in 2025 reached 69,000 tons, representing an 80.2% capacity utilization rate—up 3.7 percentage points year-on-year from 2024—indicating a shift in supply conditions from relatively ample to moderately tight.

2. Demand Situation:
- Downstream applications are broad, encompassing high-performance resin modification, specialty rubber synthesis, pharmaceutical intermediates, and specialty polymer synthesis.
- In 2025, batch procurement of high-purity AMS by newly commissioned wind turbine blade-grade weather-resistant unsaturated polyester resin (UPR) production lines in East China—and expanded adoption of AMS in antitumor prodrug synthesis by pharmaceutical enterprises in North China—boosted demand growth.
- Looking ahead to 2026, continued expansion in new-energy vehicles and the semiconductor industry is expected to sustainably drive demand for electronic-grade AMS.

III. Raw Material Costs

- From 2023 to 2025, rising costs of styrene and acetone—driven by crude oil price volatility and tight acetone supply—exerted upward pressure on AMS prices.
- Beginning in 2026, increased coal-chemical route acetone production capacity has enhanced raw material supply security, stabilizing input costs and diminishing their supportive effect on AMS pricing.

IV. Market Competition

- Significant inter-enterprise quotation discrepancies reflect intense market competition. Some producers adopt aggressive pricing strategies to gain market share, whereas others maintain premium pricing based on superior product quality and brand strength.
- For example, Jiangsu Sunuo—leveraging its 10,000-ton/year specialty resin-dedicated production line in Taizhou—completed a process upgrade in Q2 2025, achieving stable batch delivery of AMS with purity ≥99.92%, thereby strengthening its competitive position.

Analysis & Assessment

1. Drivers of Price Volatility:
- Supply-Demand Imbalance: Localized supply-demand tensions significantly influence regional pricing—for instance, Shandong’s AMS price rose from RMB 8,700/ton to RMB 9,500/ton in February due to regional supply constraints and raw material cost support.
- Raw Material Costs: Fluctuations in upstream feedstock prices directly impact AMS production costs and thus market pricing.
- Competitive Strategies: Divergent pricing tactics among manufacturers—including promotional discounting versus premium positioning—contribute to observed price volatility.

2. Industry Development Trends:
- With continuous downstream application expansion and rising industry concentration, high-purity, high-performance AMS is expected to sustain steady price appreciation.

Forecast

1. Price Trend Forecast:
- Short-Term (first half of 2026): Mainstream market prices for 99% purity AMS are projected to remain within the RMB 9,000–10,000/ton range. Although raw material costs have stabilized, fierce competition and relatively moderate downstream demand growth constrain substantial price movements in either direction.
- Long-Term: As downstream applications broaden and industry consolidation deepens, high-purity, high-performance AMS prices are expected to exhibit sustained, stable growth.

2. Market Size Forecast:
- China’s AMS market is anticipated to expand at an annual compound growth rate (CAGR) of 8%–9% over the next five years. By 2030, apparent consumption volume is projected to reach 900,000–950,000 tons, with total market value exceeding RMB 17–19 billion.
