Market Intelligence, Analysis, and Forecast for tert-Butyl Mercaptan

I. Market Intelligence

Price Information
- Domestic Market: As of April 2, 2026, the ex-factory price for imported premium-grade tert-butyl mercaptan in Zibo City, Shandong Province, stood at RMB 17,800.00 per ton; the market price for imported national standard (GB) grade 99% tert-butyl mercaptan was RMB 17,700.00 per ton.
- International Market: The global average price of tert-butyl mercaptan in 2024 was approximately USD 18,200 per ton.

Supply-Demand Dynamics
- Supply Side:
- In 2025, three listed companies—Zhejiang Xin’an Chemical Industry Co., Ltd., Jiangsu Yangnong Chemical Co., Ltd., and Hubei Xingfa Group Co., Ltd.—announced that their in-house integrated tert-butyl mercaptan production projects would achieve full commercial operation in Q2 2026. These projects collectively add 33,000 tons/year of internal consumption capacity, significantly reducing external procurement dependency while strengthening their pricing power across the industrial chain.
- In 2025, the Ministry of Ecology and Environment issued the “Access Guidelines for Sulfur-Containing Organic Compound Production”, tightening VOCs emission limits for tert-butyl mercaptan production facilities to 30 mg/m3. This regulation mandates adoption of dual-stage treatment systems comprising regenerative thermal oxidizers (RTO) coupled with alkaline scrubbers, increasing environmental compliance investment per production line by approximately RMB 21 million.
- Demand Side:
- In 2026, leading enterprises’ announced green tire expansion plans will add a total of 220,000 tons/year of isoprene rubber (IR) capacity. Based on the current process-specific consumption rate of 0.185 tons of tert-butyl mercaptan per ton of IR, this will generate an incremental raw material demand of ~40,700 tons.
- In 2025, China’s exports of para-tert-butylbenzyl mercaptan reached 186 tons, representing a 14.1% year-on-year increase, primarily destined for formulation plants in India, Brazil, and Southeast Asia. With deepening localization of supply-chain partnerships in 2026, export volume is projected to reach 210 tons—equivalent to an additional ~30 tons of domestic demand on a comparable basis.

Import-Export Status
- In 2025, China’s exports of tert-butyl mercaptan totaled 86,000 tons, up 11.7% year-on-year, mainly shipped to emerging agrochemical markets including India, Brazil, Vietnam, and Argentina. Exports to India accounted for 34.2% of the total, making it the largest single export destination. Meanwhile, imports contracted further to 9,000 tons, down 22.4% year-on-year—confirming that domestically produced tert-butyl mercaptan has fully met international mainstream standards in critical quality parameters such as purity, heavy metal residue levels, and batch-to-batch consistency.

Industry Policies
- In 2025, the Ministry of Industry and Information Technology (MIIT) and the Ministry of Ecology and Environment jointly released the “Catalogue of Green Manufacturing Technologies for Key Chemical Substances (2025 Edition)”, explicitly designating tert-butyl mercaptan as a priority alternative raw material for pesticide intermediates and pharmaceutical synthesis auxiliaries. The Catalogue mandates substitution of traditional highly toxic sulfurization reagents with tert-butyl mercaptan in green synthetic pathways for technical-grade pesticide active ingredients at a minimum rate of 35%, directly boosting industry-wide capacity utilization to 86.7% in 2025—up 7.5 percentage points from 79.2% in 2024.
- The National Development and Reform Commission (NDRC) upgraded the C2614 category (“Chemical Reagents and Auxiliaries Manufacturing”)—to which tert-butyl mercaptan belongs—to the “Encouraged” classification in the “Industrial Structure Adjustment Guidance Catalogue (2025 Edition)”. Supporting fiscal incentives include VAT refund-upon-collection, R&D expense super-deduction (150% of actual R&D expenditure for firms with R&D intensity exceeding 3.8% of sales revenue), and a preferential 13% export VAT rebate. As a result, the sector’s average effective tax burden declined from 9.4% in 2024 to 6.1% in 2025.
- In March 2025, Jiangsu Province launched the “Three-Year Action Plan for High-Quality Development of the Yangtze River Delta Advanced Fine Chemical Industry Cluster”, establishing a special technology upgrade subsidy fund pool totaling RMB 1.28 billion. Enterprises adopting continuous-flow microreactor technology for tert-butyl mercaptan synthesis are eligible for subsidies equal to 22% of equipment investment, capped at RMB 46 million per project. As of November 2025, 17 producers had completed such upgrades, achieving a 28.3% reduction in energy consumption per unit output and lowering wastewater COD discharge intensity from 42.6 kg/ton in 2024 to 29.7 kg/ton.

II. Analysis & Assessment

Strengths
- Policy Support: Multiple national and provincial policies support the development of the tert-butyl mercaptan industry—including designation as a priority alternative feedstock, tax incentives, and technology upgrade subsidies—thereby lowering operational costs and accelerating industrial upgrading and capacity utilization.
- Growing Market Demand: Expansion of green tire production and broadening export markets are driving increased demand for tert-butyl mercaptan, offering substantial growth potential.
- Quality Advancement: Domestically manufactured products now fully comply with international mainstream standards across key quality metrics; shrinking imports and rising exports attest to enhanced competitiveness of Chinese-made tert-butyl mercaptan.

Challenges
- Environmental Compliance Pressure: Stricter VOCs emission limits necessitate significant environmental investment—e.g., dual-stage RTO + alkaline scrubber systems—which may elevate production costs.
- Upstream Raw Material Price Volatility: Fluctuations in prices of upstream feedstocks such as chlorine gas and isobutylene could impact production costs and compress profit margins.
- Lengthy Certification Cycles: Downstream pesticide API customers impose stringent, multi-dimensional quality control requirements—including batch purity, heavy metal residue, and stability—resulting in an average certification lead time of 14–18 months for new entrants, raising barriers to market entry.

Competitive Landscape
- Industry concentration is rapidly increasing: the top five manufacturers held a combined market share of 64.3% in 2025—up 7.2 percentage points from 57.1% in 2024. All five have maintained stable gross margins between 28.5% and 32.1% for three consecutive years—significantly outperforming the average 19.4% gross margin for basic chemical products—reflecting strengthened technological barriers and heightened customer stickiness.

III. Forecast

Market Size
- China’s tert-butyl mercaptan market is projected to reach 542,000 tons in 2026, representing an 8.4% year-on-year growth—the pace slightly accelerating from 2025.

Price Trend
- Tert-butyl mercaptan prices are expected to fluctuate within a certain range, influenced by supply-demand dynamics, upstream raw material costs, and environmental compliance expenditures. Price increases may occur if upstream feedstock prices rise or environmental compliance costs escalate; conversely, intensified competition or overcapacity could exert downward pressure on prices.

Industry Development Trends
- Green Transformation: With tightening environmental regulations, enterprises will increasingly prioritize green manufacturing—adopting eco-friendly synthesis processes and advanced emission control systems to reduce VOCs emissions.
- Value-Added Orientation: Leading players will reinforce technological moats and deepen customer loyalty through vertical integration across the entire value chain and horizontal expansion into high-margin derivative product categories—accelerating the industry’s shift toward higher value-added operations.
- Customized Service Models: To meet diversified downstream customer needs, producers are expected to offer tailored product specifications and value-added services, thereby strengthening collaborative partnerships along the supply chain.
