The Namrup Fertilizer Complex was renamed as Brahmaputra Valley Fertilizer Corporation Limited after bi-furcation from Hindustan Fertilizer Corporation Limited from 01/04/02. It is located on the bank of dilli river in the south-western border of Dibrugarh District in Assam. It is the first factory in India, who use natural gas as basic raw material for producing nitrogenous fertilizer.

Till the sixties Namrup was not known to the rest of the country. Discovery of oil and natural gas in Naharkatiya region promoted a serious thinking on proper utilization of gas. Which had to be otherwise to be flared up.
