An email query sent to RIL remained unanswered. “Demand for polyester has been good in the last few quarters as crude prices were low. However, with the rise in crude prices, this is likely to change. For RIL, polyester is a small part of its larger petrochemical business, so I do not expect it to be a significant hit for the company at large. In addition, its share of exports to US of its total polyester production may also be lower. Having said that, one needs to look at what exactly is the duty to access the financial hit,” said an analyst.
