According to industry sources, the government is considering imposing Anti-Dumping Duty on Chlorinated Polyvinyl Chloride (CPVC) resin sourced from South Korea and China. The industry is expecting announcement from government by the middle of this month. It may be recalled here that in the month of March, the Directorate general of Trade Remedies had initiated investigation concerning imports of CPVC from China and South Korea. And the preliminary investigation had found dumping by these two countries of CPVC in India.
Its found that out of total imports of 1,62,000 tonnes of CPVC into the country, these two countries accounted for nearly 30% of them. Imports from these countries have been steadily increasing over the years. ADD is expected to vary from $2,050 to $2,850 per tonne depending upon the source.
Chlorinated Polyvinyl Chloride Resin is produced by chlorination via free radical chlorination reaction of Polyvinyl Chloride resin and is significantly more flexible and can withstand higher temperature than ordinary PVC. The chlorine content may vary from manufacturer to manufacturer. Various additives are introduced into the resin and these additives may consist of stabilizers, lubricants, impact modifiers, processing aids and pigments.
CPVC is ideally suited for self-supporting construction where temperature can go up to 900 C. CPVC has fire retardant properties. Its very difficult to ignite and tends to self-extinguish when not in direct contact of flame. It is used as a material for water piping systems in residential as well as commercial construction because it can withstand corrosive at temperatures 400 C to 500 C. Its used in hot and cold water plumbing distribution both at residential and commercial buildings, fire protection, reclaimed water piping, chilled water piping, hydronic piping and distribution. Mechanical strength of CPVC makes it a viable product to replace many types of metal pipe in condition where metal’s susceptibility to corrosion limits its use.
