Germany, the United States, and China are the leading exporters of heptanoic acid (CAS 111-14-8), collectively accounting for over 60% of global exports in 2023–2024; major importers include India, South Korea, and Brazil, with India consistently ranking first in import volume. Import volumes have risen steadily in Asia-Pacific markets amid expanding demand from pharmaceutical and plasticizer sectors, while Heptanoic acid prices remained relatively stable despite modest supply-side fluctuations.
Recent Market Dynamics of n-Heptanoic Acid
I. Price Trends
1. Domestic Market: Recent n-heptanoic acid prices have shown a slight upward fluctuation, with mainstream transaction prices ranging from 12,000 to 13,500 RMB/ton. Some high-end quotations have exceeded 14,000 RMB/ton, representing an increase of approximately 3%-5% compared to the average price of the previous month.
2. International Market: FOB China main port prices remain stable at 1,600-1,750 USD/ton. Influenced by exchange rate fluctuations and shipping costs, import costs have increased slightly, while overall international demand remains steady.
II. Supply and Demand Dynamics
1. Supply Side:
- The operating rate of major domestic producers remains stable at 75%-80%. Although some manufacturers temporarily halted production due to environmental inspections, overall capacity has not been significantly affected.
- Import volumes decreased by approximately 10% month-on-month, primarily because European suppliers reduced export quotas due to rising raw material costs.
2. Demand Side:
- Downstream industry demand is diverging:
- Demand in the coatings and inks sector grew by approximately 8%, driven by increased orders during the spring renovation peak season;
- Demand in the plastic additives sector remained flat, with some companies exercising caution in procurement due to high inventory levels;
- Demand in the fragrance intermediate sector decreased slightly by 3%, impacted by weakness in the end consumer market.
III. Costs and Profits
1. Raw Material Costs:
- The price of the primary raw material, n-heptane, increased by approximately 5% due to crude oil volatility, pushing up the production cost of n-heptanoic acid by 200-300 RMB/ton.
- Prices of auxiliary materials (such as catalysts and solvents) remained stable, having a limited impact on costs.
2. Profit Margins:
- The industry average gross margin remains at 15%-18%, a compression of approximately 2 percentage points compared to earlier periods. Some small and medium-sized enterprises have paused order acceptance due to cost pressures.
IV. Inventory and Logistics
1. Inventory Levels:
- Production enterprises' inventory cycles have shortened to 10-15 days, below the historical average of 20 days, due to increased downstream restocking demand;
- Trader inventories are neutral, with some short-term accumulations in certain regions caused by logistics delays.
2. Logistics Impact:
- Domestic inland transportation costs have risen by approximately 8% due to fuel price increases;
- Tight shipping capacity has led to delivery delays of 1-2 weeks for some export orders.
V. Policies and Industry Dynamics
1. Environmental Policies:
- Jiangsu, Shandong, and other regions have strengthened VOCs emission controls, requiring some enterprises to upgrade exhaust gas treatment equipment, which has temporarily constrained capacity.
2. Industry Events:
- A leading enterprise announced an expansion plan, expecting to add 50,000 tons/year of capacity by 2025, which may increase long-term supply pressure.
VI. Analysis and Judgment
1. Short-term Driving Factors:
- The resonance of cost support and downstream restocking demand makes prices prone to rise and difficult to fall;
- Rising logistics costs and regional supply tightening may push up local prices.
2. Risk Points:
- A significant drop in crude oil prices could weaken cost support;
- A seasonal decline in downstream demand could lead to inventory accumulation.
VII. Price Forecast
1. Next 1 Month:
- Domestic prices are expected to fluctuate within the 12,500-14,000 RMB/ton range, with the average price potentially rising to 13,200 RMB/ton;
- International FOB prices are expected to remain within 1,650-1,800 USD/ton, with increased elasticity due to exchange rate fluctuations.
2. Next 3 Months:
- If raw material costs remain stable and demand does not significantly decline, the price center may rise to the 13,500-14,500 RMB/ton range;
- Caution is advised regarding the risk of oversupply due to the early release of expansion plans.
Heptanoic acid is a colorless to pale yellow liquid with a pungent, rancid odor and moderate volatility; it melts at −7.5 °C and boils at 223 °C. It is a straight-chain saturated carboxylic acid (C₇H₁₄O₂) classified as an aliphatic organic chemical and fatty acid derivative. Industrially, it serves primarily as a chemical intermediate in the synthesis of esters, plasticizers, lubricants, and corrosion inhibitors. Its esters are widely used in fragrances and flavorings, while the acid itself finds application in the production of coatings, metalworking fluids, and specialty polymers.
Intermediates of Liquid Crystals
Heptanoic acid has a disagreeable rancid odor. The spectroscopically pure acid exhibits a faint tallow-like odor. Heptanoic acid may be prepared by oxidation of heptaldehyde with potassium permanganate in diluted sulfuric acid.
This chemical is included in Fine Chemicals. See more about what is Heptanoic acid and Heptanoic acid SDS information.
