Further, there is also a conflict of interest since the raw material and the formulations are developed and patented by the institute, which is also the agency for certifying pollution standards of the final product.
However, not all the manufacturers are raising the allegation. P Ganesan, president of Tamil Nadu Fireworks and Amorces Manufacturers Association (TANFAMA) and director of Vinayaga Sonny Fireworks Group, one of the largest fireworks manufacturers in the country, says there are no such restrictions and the companies can purchase the raw material from anywhere they want. "There are different types of additives. We can import also, if needed," he said.
