Ramesh Shah, Jahanvi Trading Co, has been a dealer for the past 33 years. The company deals in Vasavdatta and Jaypee cement along with Hyderabad Industries AC sheet, Shree Om Steel, Roofit Mix Industries. The company mostly supplies cement for infrastructural projects. "Clients mostly prefer OPC 43 grade cement and OPC 53 grade cement," said Shah and added, "We deliver cement in Navi Mumbai and Raigad District." The company stocks up to 100 mt of cement. "The basis of levelling excise duty is completely wrong. It is unfair and ambiguous," said Shah. He further added that there should be change in the present taxation system. Shah also suggested that PPC should be used more in all the government projects. About the margins that the manufacturers offer, Shah said that it should be increased. "Though smaller companies offer better margin, the bigger companies need to revise their margins." Ramesh Shah is a member of Cement Stockist Association of Bombay, Panvel and New Panvel.
