Shares of Chemplast Sanmar Ltd surged 4.85% to ₹449.40 on Monday, August 18, after the Directorate General of Trade Remedies (DGTR) recommended the imposition of anti-dumping duty on imports of PVC suspension resin. The move is expected to provide a boost to domestic producers, including Chemplast Sanmar and DCM Shriram, by curbing cheaper overseas inflows.
The DGTR investigation, which covered imports from key supplying nations, concluded that dumped PVC volumes were causing material injury to Indian manufacturers. The proposed duties, once notified by the finance ministry, will help create a level playing field and protect margins in the domestic market.
PVC suspension resin is a critical raw material for applications across pipes, fittings, profiles, films, and sheets, with strong linkages to the housing and infrastructure sectors. Analysts expect the duty support to benefit domestic players in sustaining pricing power and improving capacity utilisation.
Chemplast Sanmar’s stock has risen nearly 18% in the past month, with today’s gains extending its strong momentum.
