Market Segmentation

The global chlorine market share is classified into form, application, and end user.

• The liquid segment accounted for the largest share in 2024, approximately 60%, and is anticipated to grow at a significant CAGR during the forecast period.           

Based on the form, the global chlorine market is divided into liquid and gas. Among these, the liquid segment accounted for the largest share in 2024, approximately  and is anticipated to grow at a significant CAGR during the forecast period. This is because liquid chlorine is easier to store, transport, and handle, making it safer for use across applications. It is widely used in water treatment, sanitation, and various industrial processes, offering greater convenience and efficiency compared to gaseous chlorine.

• The EDC/PVC segment accounted for the highest market revenue in 2024, approximately 40%, and is anticipated to grow at a significant CAGR during the forecast period.

Based on the application, the global chlorine market is divided into  organic chemicals, inorganic chemicals, isocyanates, chlorinated intermediates, propylene oxide, pulp & paper, , aromatics & water treatment. Among these, the segment accounted for the highest market revenue in 2024, approximately  and is anticipated to grow at a significant CAGR during the forecast period. This is because chlorine is a key raw material in ethylene dichloride EDC and polyvinyl chloride PVC production, which are extensively used in construction, piping systems, electrical cables, and various infrastructure applications, driving strong and consistent demand.

• The chemicals segment dominated the market in 2024, approximately 35%, and is projected to grow at a substantial CAGR during the forecast period.

Based on the end user, the global chlorine market is divided into water treatment, pharmaceutical, chemicals, paper and pulp, plastic, pesticides, and others. Among these, the chemicals segment dominated the market in 2024, approximately and is projected to grow at a substantial CAGR during the forecast period. The market dominance is due to the extensive use of chlorine as a key raw material in producing a wide range of industrial chemicals and intermediates, including solvents, plastics, and specialty compounds, supporting diverse applications across manufacturing, construction, and chemical processing industries.
