The impact of price changes (at a level of market) on the other market levels (transfer of prices) will affect welfare of producers, marketing agents as well as consumers. In this study, asymmetric tea market is investigated through an application of Johansen co-integration analysis and Error Correction Model (ECM Model) to time series of 1976-2009. Co integration method used in the import market suggests at least a long-run relationship between domestic and import prices. Granger causality test revealed that a one-way causality relationship exist between the import and domestic prices of tea. An estimation of the price transmission model of import prices to domestic ones reflects the existence of asymmetry in tea import market of Iran. The concentration ratio and Herfindahl-Hirschman indicators, respectively recorded as 76% and 3893.29 reveal the presence of a high concentration and market power of both countries India and Sri Lanka in Iran's market of tea imports.
