Elemental chlorine, traded primarily as a liquefied gas, is a foundational industrial chemical used in PVC production, water treatment, and the synthesis of a broad range of organic and inorganic compounds. As a highly toxic substance, chlorine imports are subject to stringent DOT hazardous materials transport regulations and EPA Risk Management Program requirements at receiving facilities. Because chlorine is typically produced close to its point of use due to handling hazards, cross-border trade volumes are relatively limited and tend to reflect regional supply imbalances rather than global commodity flows.
