About Jute

 

 



Raw jute quality and jute product's quality testing is essential before export.  The jute products quality includes physical test, chemical and analytic test, biological ingredient test, jute composites test, ecological test.  It also requires well equipped laboratories and testing equipments.  In India particularly in West Bengal many jute testing services are available.  The most reliable and prominent test services are from Indian Jute Industries Research Association (IJIRA).  IJIRA jute test services equipped with modern laboratory equipments and well trained experts team.

India is the largest producer of jute goods in the world, while Bangladesh is the largest cultivator of raw jute.  The cultivation of Jute in India is mainly confined to the eastern region states - West Bengal, Bihar, Assam, Tripura, Meghalaya, Orrissa and Uttar Pradesh.  Nearly 50 percent of total raw jute production in India alone figures in West Bengal.
