Chlorine: Trading

When a toxic gas sells for less than nothing

What this tab covers How it is bought and sold: buyers and sellers, price benchmarks and who publishes them, exchanges, contract types, traders, how Indian buyers price it, recent price points, and good sources to follow.

Who buys, and where

  • Near the producer: by pipeline across the fence, or liquid chlorine in tonners, rail tank cars and road tankers within a few hundred km

Who sells, and from where

  • Mostly captive: converted on site into EDC, phosgene, HCl or hypochlorite; merchant sales to water works, chemical intermediates makers and paper mills

Contract types

  • Long-term pipeline supply agreements with cost-plus or ECU-linked formulas
  • Monthly or quarterly contracts for liquid chlorine in cylinders and tankers
  • Tolling: chlorine user supplies power or salt and pays a fee

Traders and distributors

  • Very little trading; producers sell direct

How Indian buyers price it

  • Producer list prices ex-works by state; chlorine realisations in Gujarat and Tamil Nadu are often near zero or negative and are netted against caustic
  • Indian producers report 'ECU realisation' in results: caustic price plus chlorine price
