Tetrahydrothiophene Market Intelligence Report (May 20–27, 2026)

I. Price Dynamics
1. Quotations in Shandong Province
- Shandong Hongyang Chemical Co., Ltd.: RMB 120,000/ton (99% purity), quoted on May 25, delivery location: Shandong Province; valid for 3 days.
- Shandong Zhihengda Import & Export Co., Ltd.: RMB 120,000/ton (99% purity), quoted on May 25, delivery location: Shandong Province.
- Shandong Qiangsen Chemical Co., Ltd.: RMB 92,000/ton (available in purities of 99%, 99.5%, and 99.9%), quoted on May 24, delivery location: Zibo City, Shandong Province.
- Shandong Xima Supply Chain Management Co., Ltd.: RMB 92,000/ton (99% purity), quoted on May 24, delivery location: Zibo City, Shandong Province.
- Shandong Beilu Hengsheng Chemical Co., Ltd.: RMB 100,000/ton (purity unspecified), quoted on May 24, delivery location: Jiangsu Province.

2. Regional Price Spread
- Mainstream quotations in Shandong Province range between RMB 92,000 and RMB 120,000/ton. The price gap between high-purity (99.9%) and standard-purity (99%) grades has narrowed, indicating reduced market sensitivity to purity differentials.
- The quotation from Jiangsu Province (Beilu Hengsheng) stands at RMB 100,000/ton—lower than some high-end Shandong quotes but higher than the lowest Shandong quotations—reflecting the influence of regional logistics costs and brand premium.

3. Historical Price Comparison
- March 2026: Shandong Qiangsen Chemical quoted RMB 105,000/ton (99.9% purity); Laya Chemical quoted RMB 94,000/ton (99.7% purity).
- August 2025: Shandong Hongyang Chemical quoted RMB 120,000/ton (99% purity), identical to its current quote—suggesting short-term price stability.

II. Market Drivers
1. Supply-Demand Balance
- Supply Side: Active quotations from Shandong-based producers—and cross-regional supply by Beilu Hengsheng—indicate ample production capacity. However, the absence of a significant price premium for high-purity (99.9%) grades versus standard (99%) grades suggests potential oversupply risk.
- Demand Side: As an odorant for natural gas, tetrahydrothiophene demand is strongly correlated with natural gas consumption. With the summer peak-gas-consumption season approaching in 2026, downstream procurement remains steady—no large-scale pre-season stockpiling has occurred.

2. Cost and Profitability
- Raw material sulfur prices have remained relatively stable, providing limited cost support for tetrahydrothiophene.
- Profit margins vary by purity grade: profit margins for high-purity (99.9%) products may be lower than those for 99% products, as the technological barrier and associated cost differential have diminished.

3. Policy and Environmental Factors
- Stricter gas safety regulations are boosting demand for odorants; however, competition from alternative odorants—such as ethanethiol—is constraining upward price pressure.

III. Competitive Landscape
1. Key Players
- Shandong Qiangsen Chemical: Offers flexible pricing across multiple purity grades and holds a relatively high market share.
- Shandong Hongyang Chemical: Maintains a premium pricing strategy, potentially targeting high-end or brand-sensitive market segments.
- Beilu Hengsheng: Leverages logistics advantages to expand beyond its home region through cross-provincial supply.

2. New Entrants
- Kandisi Chemical (Hubei): Offers small-batch retail (RMB 55/kg, packaged in 200-kg drums), targeting SME customers—but has yet to exert meaningful competitive pressure on the mainstream market.

IV. Outlook (June–August 2026)
1. Price Trends
- Short Term (June): Mainstream quotations in Shandong Province are expected to remain within RMB 92,000–110,000/ton; downward pressure on high-purity product prices may intensify.
- Medium Term (July–August): Summer peak natural gas demand could stimulate consumption, but persistent oversupply is likely to cap price gains. The expected trading range may narrow to RMB 90,000–105,000/ton.

2. Market Risks
- Alternative Odorant Competition: A decline in ethanethiol production costs could divert part of the demand away from tetrahydrothiophene.
- Environmental Regulation: Potential upgrades to odorant quality standards could revive demand for high-purity grades—but near-term impact is expected to be limited.

3. Strategic Recommendations
- Downstream Users: Consider procuring inventory ahead of summer at current favorable price levels—but closely monitor supplier inventory status.
- Producers: Optimize product mix by refining purity-grade strategies and reducing production costs for high-purity grades to better compete against alternatives.
