Heptane

Market Intelligence Report on n-Heptane – Recent Commodity Market Dynamics

I. Price Dynamics

1. Benchmark Price Fluctuations:
- As of July 20, 2026, the Business Network (Shengyishe) benchmark price for n-heptane stood at RMB 14,400.00 per metric ton, representing an 8.27% increase from the beginning-of-month price of RMB 13,300.00 per metric ton.
- On July 16, the benchmark price was RMB 14,500.00 per metric ton, up 9.02% from the beginning-of-month level.
- On July 9, the benchmark price was RMB 14,240.00 per metric ton, reflecting a 5.26% increase month-on-month.

2. Inter-Enterprise Quotation Disparities:
- Significant quotation differences exist across enterprises: e.g., Nanjing Baitu Chemical Co., Ltd. quotes RMB 13,700 per metric ton for domestic premium-grade (99% purity) n-heptane, whereas Shandong Yihe Fine Chemical Co., Ltd. quotes as high as RMB 15,700 per metric ton.
- Low-end quotations—such as Jinan Zesheng Chemical Co., Ltd.’s RMB 8,600 per metric ton—are primarily attributable to variations in product quality, brand reputation, and regional factors.

3. Regional Price Differentials:
- Pronounced price divergence exists within Shandong Province: the price gap between Jinan and Zibo exceeds RMB 5,000 per metric ton. For instance, the price range for domestic premium-grade (99% purity) n-heptane in Jinan is RMB 9,500–17,000 per metric ton, while Zibo’s top-grade product is priced at RMB 14,200 per metric ton and standard 99%-purity products as low as RMB 9,800 per metric ton.
- In Nanjing, Jiangsu Province, the market price for domestic premium-grade (99% purity) n-heptane is RMB 15,600 per metric ton; meanwhile, in Jinan, Shandong Province, quotations for the same grade vary widely—e.g., RMB 15,300 and RMB 16,600 per metric ton.

II. Market Analysis

1. Supply-Demand Balance:
- Supply Side: There are currently 10 domestic coal-based n-heptane producers (9 operating normally), with aggregate annual capacity exceeding 100,000 metric tons. An additional 4–6 new facilities are expected to come online during 2026–2027, potentially raising total national capacity to 190,000–200,000 metric tons. Shandong Province will account for roughly half of nationwide production (6–7 plants), while Northwest China will add 3–4 new facilities.
- Demand Side: Annual actual demand stands at approximately 30,000 metric tons, with pharmaceutical intermediates constituting the primary application (>90% share). End-use is predominantly in drum-packaged form, resulting in low demand elasticity. Export volume totals ~25,000 metric tons annually—representing 40–50% of total output—but global economic slowdown has reduced orders from key markets such as India, placing inventory pressure on export-dependent enterprises.

2. Cost Support:
- Coal-derived normal paraffinic naphtha commands a premium of RMB 1,200–1,300 per metric ton over mixed coal-derived naphtha, underpinning the cost floor for n-heptane. However, recent oversupply has driven down coal-derived naphtha prices—from nearly RMB 9,000 to ~RMB 7,000 per metric ton—a decline of nearly RMB 2,000 per metric ton.

3. Impact of Substitutes:
- n-Hexane faces severe overcapacity (annual capacity expanded by 130,000 metric tons to 400,000 metric tons in 2024), resulting in widespread price inversion (60% of output priced below No. 6 solvent oil), which indirectly pushes up n-heptane pricing.

4. Challenges Posed by New Entrants:
- Quality inconsistencies plague several newly launched producers: toluene content reaches 500–600 ppm and bromine index exceeds specifications, rendering their output unsuitable for high-end pharmaceutical applications—thereby widening the price spread between premium and standard grades.

5. Absence of Industry Standards:
- No unified national standard currently governs n-heptane; analytical reports issued by different manufacturers employ inconsistent testing criteria, impeding standardized market development.

III. Outlook and Projections

1. Price Trend:
- The benchmark price is expected to remain in a modestly upward, range-bound trajectory, fluctuating within RMB 13,500–14,500 per metric ton.
- Should overcapacity intensify, prices may retreat below RMB 12,000 per metric ton—approaching cost-floor levels.

2. Supply-Demand Dynamics:
- Gradual release of new capacity and ongoing competitive pressure from low-priced co-products will persist; however, stable demand from pharmaceutical intermediates limits downside risk.
- In the long term, excessive capacity expansion will inevitably lead to structural oversupply, compelling prices toward a rational equilibrium level.

3. Industry Consolidation:
- Producers failing to meet quality standards or lacking cost competitiveness will be phased out; leading enterprises’ operating rates may fall below six months annually, triggering a fundamental reshaping of the competitive landscape.

4. Capacity Rationalization:
- The industry is entering a phase of capacity rationalization (“capacity cleanup”). High-quality, cost-efficient enterprises will gain greater market share, enhancing overall market concentration.

5. Standardization Initiatives:
- As the sector matures and standardization advances, a national standard for n-heptane is anticipated—supporting healthy, sustainable market development.
