Withdraw 5% import duty on naphtha: HPLPress Trust of India / Kolkata April 14, 2008Haldia Petrochemicals Ltd (HPL) has urged the Union Finance Ministry to withdraw the 5 per cent import duty on naphtha levied in the Budget this year.HPL was the only petrochemicals firm in the country which would be directly affected by the imposition of the levy, sources in the company told PTI.Other companies like GAIL and Reliance would not be affected as the former used gas cracker technology and the latter has its own source of naphtha supply.HPL sources said the company had already made several representations to the Finance Ministry through industry bodies like the CII and also through the West Bengal government.
