Cashew Nut Shell Liquid (CNSL oil, Cashew Shell Oil, CNSL Resin) is a bypass-product of the cashew processing factory. The cashew Nut Shell take up 70 % weight of raw cashew nut. The cashew Nut Shell has a shell of about 1/8-inch thickness inside which is a soft honeycomb structure containing a dark reddish brown viscous liquid. It is called cashew nut shell liquid (CNSL), which is the pericarp fluid of the cashew nut. Cashew nutshell contains up to 25 – 35% oil, this is a precious oil also known as cashew nut shell oil, which is being imported from many countries around the world. Last year, Viet Nam exported more than 600,000 tons of cashew oil. Mainly market to China, South Korea, Indonesia, and Spain. Previously, China was the main market, but now Korea is leading. CNSL cashew supplier, CNSL cashew shell oil & Cashew Supplier In Vietnam.
