Sudan is the world's largest producer of gum Arabic. All the gum Arabic produced in Sudan, mostly hashab, is exported. From the 50's to the early 90's, Sudanese gum accounted for 80 percent of the global gum trade. From 50,000 tons per annum in the 50's and 60's, Sudan's gum exports declined to around 25,000 tons in the late 80's.
