Chlorine Market Size Projected to Reach $71.92 billion by 2034 | 5.6%

According to Straits Research, the global chlorine market size was valued at $44.05 billion in 2025 and is projected to grow from $46.51 billion in 2026 to $71.92 billion by 2034 at a CAGR of 5.6% during the forecast period 2026-2034.

Polyvinyl chloride, consisting of 57% of chlorine and 43% of carbon, is used in an array of applications across different industries. Higher chlorine content makes polyvinyl chloride compatible with a wide range of material and improves its flame-retardant property and recycling ability. PVC is among the most utilized polymer for applications ranging from window frames to medical devices and blood storage bags to cable and wire insulation. However, building and construction, medical devices, and automobiles have been the primary application areas of polyvinyl chloride. Additionally, the rising demand for electric vehicles is expected to boost the demand for polyvinyl chloride. The weight of the vehicle plays a vital role in the success of an electrically powered vehicle, and polyvinyl chloride is among the lightest materials used in the automotive industry.  

The American Society of Mechanical Engineers has estimated that companies can increase cost saving by 25–50% by adopting plastic parts. Polyvinyl chloride is the second largest plastics used in the automotive sector after polypropylene.

Asia-Pacific is the largest consumer of chlorine, owing to the enormous demand from China, India, and Southeast Asian countries. Asia-Pacific houses prominent chemical and automotive sectors, thereby the region consumes a significant amount of chlorine.
