DIBK (Diisobutyl Ketone) Market Dynamics Intelligence (May 27, 2026)

I. Recent Price Volatility (May 18–24, 2026)
| Date | Trader/Brand | Origin/Delivery Location | Purity | Quotation (CNY/ton or CNY/kg) | Price Trend |
|------------|------------------------------------|--------------------------|--------|------------------------------|----------------------------------|
| 2026-05-18 | Ait (Zhejiang) Supply Chain (Dow) | Zhejiang Province | 96% | 28,000 | Stable (as of May 20) |
| 2026-05-18 | Hubei Qiqiba Chemical Co., Ltd. | Wuhan, Hubei Province | 99% | 18.5/kg | Stable (as of May 20) |
| 2026-05-18 | Shandong Qiangsen Chemical Co., Ltd. | Zibo, Shandong Province | 99% | 19,000 | Stable (as of May 20) |
| 2026-05-20 | Ait (Zhejiang) Supply Chain (Domestic) | Zhejiang Province | 99% | 24,000 | Unchanged vs. May 18 |
| 2026-05-20 | Shandong Xima Supply Chain | Zibo, Shandong Province | 99% | 20,000 | +5.3% vs. May 18 |

Key Changes:
– Widening price divergence in Shandong: price gap between Qiangsen Chemical (CNY 19,000/ton) and Xima Supply Chain (CNY 20,000/ton) has expanded to CNY 1,000/ton.
– Domestic supply (Ait Supply Chain) priced CNY 4,000/ton lower than imported Dow material, indicating accelerating domestic substitution.

II. Market Driving Factor Analysis
1. Capacity Expansion & Supply Structure
– New capacity ramp-up: Anhui Zhonghuifa (1,000 tons/year) and Henan Ruibai (1,050 tons/year) projects commenced operations in 2024; however, actual DIBK output remains volatile as it is primarily produced as a co-product alongside methyl isobutyl ketone (MIBK).
– Regional supply disparity: The East China region (Zhejiang, Shandong) accounts for over 60% of national DIBK capacity; its logistical cost advantage intensifies regional price competition, whereas the Central China region (Hubei) relies more on local demand, exhibiting stronger pricing resilience.

2. Downstream Demand Structure
– Coatings & Solvents: Account for 55% of total demand; depressed real estate sector has reduced coatings manufacturers’ operating rates in East China by 8% YoY, dampening DIBK consumption.
– Fragrances & Intermediates: Represent 30% of demand; export growth of fragrance ingredients such as menthol (+12% YoY) supports demand for premium-grade DIBK (99% purity).
– Other Applications: Adhesives, electronic cleaning agents, etc., account for 15% of demand—stable but relatively small-scale.

3. Cost & Profitability
– Acetone feedstock price: Average acetone price stood at CNY 6,200/ton as of May 24, up 15% from beginning of year, increasing DIBK production costs by approximately CNY 800/ton.
– Industry profitability: For example, Shandong Qiangsen Chemical’s current quoted price yields a gross margin of ~18%, down 5 percentage points YoY; some producers are maintaining margins by lowering product purity (e.g., offering 96% instead of 99%).

III. Price Forecast & Risk Alerts
1. Short-Term Outlook (1–3 months)
– Price Range: Shandong mainstream prices expected to remain within CNY 18,500–20,500/ton; Central China region projected at CNY 18,000–19,000/kg (equivalent to ~CNY 18,000–19,000/ton when converted).
– Key Catalysts: Traditional low-demand season for coatings industry in early June may push prices toward CNY 18,000/ton; sustained acetone price increases could trigger DIBK price hikes of CNY 500–800/ton.

2. Medium-to-Long-Term Trends (6–12 months)
– Overcapacity Risk: Anhui Zhonghuifa’s Phase II project (2,000 tons/year) scheduled for H2 2026 will push national DIBK capacity above 100,000 tons/year, while demand growth remains modest at only 3–4% annually—exerting downward pressure on prices.
– Deepening Domestic Substitution: As domestic DIBK purity improves to 99.5%, import substitution rate—currently ~30%—may rise to ~50%, constraining premium-tier pricing (e.g., Dow-branded material).

3. Risk Alerts
– Environmental Regulations: Tighter VOCs emission standards could accelerate coatings industry’s shift toward water-based alternatives, reducing DIBK demand.
– International Trade Frictions: Potential U.S. tariff hikes on Chinese chemical products may raise import costs, though domestic supply now dominates the market—impact expected to be limited.

IV. Operational Recommendations
– Downstream Users: Consider signing quarterly contracts to lock in pricing and mitigate volatility risks during the seasonal low-demand period.
– Traders: Monitor inter-regional price arbitrage opportunities between Shandong and Central China—current spread offers ~CNY 500–1,000/ton potential.
– Producers: Optimize co-product recovery efficiency; enhancing DIBK yield (current industry average: 85%) can reduce unit production costs.
