Tanzania has close ties with Comoros in terms of proximity of the countries, resemblance of culture and language despite this Tanzania exports are low; in 2013 Tanzania total export value was at USD. 851000 approximately 0.07% of Comoros total import value of USD.115Million, furthermore lack of adequate study on Tanzania exports to Comoros calls for the need of Tanzania to know the opportunities in Comoros by assessing which products to exports and Tanzania's comparative advantage. This study uses secondary research methods by analyzing literature and data retrieved from ITC, WITS and other reliable sources specifically: main imports and exports of Comoros; main Tanzania agricultural Exports to Comoros and Tanzania's Comparative advantage of main agricultural exports to Comoros. The Vollrath Indices (1991) namely: relative trade advantage (RTA) , the logarithm of the relative export advantage (log RXA), and the revealed competitiveness (RC) were used to calculate Tanzania's and Other Exporters to Comoros (Pakistan, United Arab Emirates, Vietnam, France, India, Thailand, Mauritius and Madagascar) comparative advantage in exporting agricultural exports at global level.
