II. Market Size and Growth
- 2025 Market Size: China’s octadecane industry achieved a market size of RMB 328 million, reflecting a 7.3% year-on-year growth and maintaining a compound annual growth rate (CAGR) of over 6.5% for three consecutive years.
- 2026 Forecast: The market size is projected to reach RMB 352 million, representing another 7.3% YoY growth; the share of high-purity products (≥99.9%) is expected to exceed 16.5%, while export dependence is forecast to rise to 28.3%.

III. Supply-Demand Structure
- Supply Side:
Key domestic producers include Jiangsu Hualun Chemical Co., Ltd., Zhejiang Royal Medchem Co., Ltd., and Shandong Jinling Chemical Co., Ltd., collectively accounting for approximately 61.5% of total industry capacity in 2025.
The high-end segment (≥99.9% purity) is dominated by Jiangsu Alpha Pharmaceutical Co., Ltd. and Zhejiang Xinhua Chemical Co., Ltd., which jointly held 78% of high-end capacity in 2025.
The industry’s average gross margin in 2025 stood at 38.6%, significantly higher than the average gross margin of basic chemical products (22.4%).
- Demand Side:
In 2025, demand growth drivers included: new energy supporting energy storage materials (42%), import substitution for biomedical testing reference standards (19%), and emerging applications such as electronic specialty gas purification additives and high-end lubricant additives (accounting for the remainder of incremental demand).
In 2026, emerging application segments—including coating additives for new energy battery separators and bonding promoters for semiconductor packaging—are expected to scale up significantly; pre-orders for high-purity electronic-grade octadecane surged 43.8% year-on-year.

IV. Policies and Standards
- National Policies:
The “14th Five-Year Plan Implementation Scheme for New Energy Storage Development” explicitly identifies organic phase-change materials (PCMs) as a key area for technological breakthroughs; related demonstration project investments are projected to reach RMB 1.28 billion in 2026.
The “First-Batch Application Demonstration Guidance Catalogue for Key New Materials (2025 Edition)” includes high-purity octadecane among supported items, offering premium subsidies covering up to 30% of insurance costs and a 15% VAT immediate refund policy.
- Industry Standards:
The General Technical Requirements for Certified Reference Materials for Chemical Analysis (GB/T 28887–202X), revised under the leadership of the National Institute of Metrology of China, will be implemented in 2026. It mandates a minimum purity of ≥99.995% for Grade-I certified reference materials, thereby accelerating domestic substitution of high-purity octadecane.

V. Technological Advancements
- SINOPEC Research Institute of Petroleum Processing and Jiangsu Huachang Chemical Co., Ltd.: Their joint pilot-scale project on octadecane-based lubricant additives successfully completed process validation in Q4 2025 and entered mass production in 2026, with an estimated annual incremental demand of ~860 tons and corresponding output value of ~RMB 49 million.
- Green Manufacturing: In 2025, the industry’s average comprehensive energy consumption per unit product declined to 0.83 tons of standard coal per ton—a 14.4% reduction compared to 2023—and green process upgrades are expanding from leading enterprises to mid-tier manufacturers.

Analysis & Assessment
1. Price Divergence: Prices in Suzhou, Jiangsu Province, are notably higher than those in Liaocheng, Shandong Province—reflecting regional supply-demand imbalances and brand premium. High-end markets (≥99.9% purity) maintain stable, elevated pricing due to high technical barriers and lengthy certification cycles.
2. Growth Drivers: Demand from new energy and biomedical sectors has become the core engine of growth; supportive policies and technological advances—including high-purity domestic substitution and commercialization of lubricant additives—reinforce structural industry tailwinds.
3. Competitive Landscape: Leading enterprises have established moats through technology monopolies (e.g., CR2 for electronic-grade capacity reaches 78%) and policy advantages (e.g., first-batch application subsidies), whereas SMEs face dual pressures from capacity expansion constraints and stringent certification requirements.

Future Outlook
1. Price Trend: Prices for high-end products are expected to remain firm or rise modestly, driven by robust new energy demand; industrial-grade prices may face downward pressure from increased capacity, though rising environmental compliance costs provide a floor.
2. Market Size: The market is projected to sustain a ~7% CAGR during 2026–2027, exceeding RMB 400 million by 2027, with high-purity product share surpassing 20%.
3. Technology Directions: Nanocomposite phase-change materials, bio-based synthesis routes, and integrated intelligent thermal-control systems will emerge as key R&D priorities—driving industry transformation from “raw material supplier” to “integrated solution provider.”
4. Risk Alert: Key risks include volatility in international crude oil prices impacting raw material costs, and potential restrictions on exports to the EU arising from REACH regulation updates.
