Carbon Disulfide Market: Market Size & Forecast 2026

Carbon disulfide is a colorless, highly flammable liquid with the formula CS2 that serves as a key building block in several industrial value chains. The largest single end use is the dissolution of cellulose to produce viscose staple fiber, filament yarn, and cellophane film, with secondary consumption in xanthates for mineral processing, rubber vulcanization accelerators, and agrochemical synthesis. Market size and growth figures for this chemical are produced by private commercial intelligence providers rather than official statistical agencies, which instead track environmental emissions of CS2 in air.

• •Estimated global market value of around USD 3.35 billion in 2025, with a projected CAGR of roughly 6.5-6.7%.
• •Rayon and viscose fiber production is the single largest application segment.
• •Atmospheric anthropogenic CS2 emissions are estimated at approximately 2.52 Tg per year globally.

Rising demand for affordable regenerated-cellulose fibers in apparel and hygiene applications continues to anchor CS2 consumption, particularly in Asian manufacturing hubs. Growth is reinforced by expanding use of rubber vulcanization accelerators in tire production, and by sustained demand for CS2-derived agrochemicals such as metam-sodium soil fumigants. At the same time, tightening workplace exposure limits and air-quality rules are pushing producers to install better capture and abatement systems, which adds to demand for higher-purity grades and supporting services.

• •Continued expansion of viscose and rayon capacity to meet textile and nonwoven demand.
• •Growth in tire and rubber goods manufacturing in Asia driving accelerator consumption.
• •Regulatory pressure on CS2 emissions spurring investment in capture, recovery, and abatement technology.

By application, the market is typically segmented into viscose/rayon fiber and cellophane, rubber chemicals, agricultural chemicals, mining and mineral processing (xanthates), and pharmaceutical and fine chemical intermediates. By grade, it is split between industrial/technical grade for large-volume uses and higher-purity grades for specialty chemical synthesis. Geographically, Asia-Pacific, led by China, India, and Indonesia, dominates both production and consumption because of its concentration of viscose fiber, rubber, and agrochemical plants, while Europe and North America represent smaller but more regulated markets focused on specialty grades and emissions-controlled operations.

• •Viscose/rayon fiber and cellophane account for the majority of global CS2 consumption.
• •Asia-Pacific is the largest producing and consuming region, anchored by Chinese and Indian fiber capacity.
• •Europe and North America focus on specialty grades and on emissions-controlled, lower-volume production.

What are the recent trends and outlook?

The medium-term outlook for CS2 remains positive in volume terms but is increasingly shaped by environmental, safety, and substitution pressures. Producers are investing in closed-loop process designs, tail-gas treatment, and improved solvent recovery to reduce fugitive emissions, while research into lyocell-type and other closed-circuit cellulose dissolution routes is gradually creating alternative pathways that may displace traditional viscose over the longer term. Demand from electric vehicle tires, high-performance rubber goods, and agrochemical applications in developing regions is expected to offset the slow erosion of CS2 use in mature textile markets.

• •Adoption of closed-loop viscose processes and stricter recovery of CS2 from tail gases is accelerating.
• •Alternative cellulose dissolution technologies such as lyocell represent a long-term substitution risk for viscose-grade CS2 demand.
• •Stronger growth in rubber accelerators and agrochemicals, particularly in Asia, is expected to support continued mid-single-digit market expansion through the forecast period.
