Tamil Nadu is one of the major non basmati rice producing state. About 5% of non basmati rice is exported through the ports in Tamil Nadu. Export of non basmati rice is increasing over the years. In this context, the present study aimed to measure the growth, instability, and structural changes in the export of non-basmati rice from Tamil Nadu ports. The study found that the export of Matta, Sonamasuri, Idly rice, Ponni varieties had grown with high instability. In terms of milling type, full boiled and raw rice had grown significantly at 9.4% and 8.65% per annum, respectively with high instability. Sonamasuri and Ponni varieties, parboiled and raw rice milling types had high probability of retention than other varieties and milling types in export trade. The instability in export quantity and value was higher after rice export ban period than the pre ban period. Among the importing countries, it was found that Singapore, UAE, and Sri Lanka had higher probability of retention of share of non basmati rice exports.
