As of November 1, 2025, the average domestic price of n-Heptane stood at RMB 14,400 per metric ton, representing a week-on-week decrease of RMB 900, or -5.88%. Converted at the current exchange rate of 7.1, the price equals approximately USD 2,028/MT.

This downward movement indicates a short-term correction in the n-Heptane market, primarily due to sluggish demand from the pharmaceutical and fine chemical sectors. While production remained stable, downstream buyers adopted a cautious purchasing strategy amid volatile crude oil costs and declining solvent prices.

Looking ahead, the n-Heptane price trend is expected to remain weak in the short term. However, should crude oil prices stabilize and pharmaceutical sector demand recover, moderate price adjustments may occur in the following weeks.

Market participants also reported increased inventories in major production bases, further exerting pressure on spot prices. In response, traders have been offering discounts to stimulate sales, particularly in East and North China.

Cyclopentane Weekly Price Update | Slight Increase to RMB 9,000 (≈ USD 1,229) per Ton

Date: November 1, 2025

---

Market Overview

As of November 1, 2025, the Chinese Cyclopentane market recorded a mild upward adjustment. The average weekly price stood at RMB 9,000 per ton (≈ USD 1,229), marking a 0.45% increase (RMB +40) compared with the previous week. The highest transaction price remained stable at RMB 9,300 per ton, showing limited volatility in trading activity.

---

Market Dynamics

The slight price increase was mainly attributed to steady demand from the insulation and refrigeration sectors, where Cyclopentane continues to serve as a key blowing agent for polyurethane foam production.
At the same time, feedstock costs for light hydrocarbons showed minor fluctuations, which moderately supported the overall price stability in the Cyclopentane market.

In regional terms, East China producers reported stable ex-factory offers, while North China markets saw slightly firmer sentiment amid constrained logistics and limited spot supply.

---

Supply and Demand Outlook

Most domestic producers maintained normal operating rates, and inventory levels remained moderate, preventing sharp price movements. However, demand recovery from home appliance and sandwich panel manufacturers is expected to lend mild upward support in the coming weeks.

Export activity also remained stable, particularly toward Southeast Asia and the Middle East markets, where Cyclopentane is favored as a non-ozone-depleting alternative to CFC and HCFC blowing agents.

---

Price Forecast

In the short term, Cyclopentane prices are expected to hover around RMB 8,900–9,300 per ton (≈ USD 1,215–1,270), with sentiment driven by seasonal demand patterns and crude oil trends.
Should upstream naphtha and isopentane prices strengthen further, downstream quotations may adjust accordingly in late November.
