MOSCOW, May 6 (Reuters) - Kazakhstan and Russia have allowed Kazakh refinery Condensat to export 225,000 metric tons of gasoline this year that will be produced from naphtha supplied by Russia's Tatneft, according to documents seen by Reuters and industry sources.

Russia has curbed gasoline exports amid fears of domestic shortages, and many countries have imposed sanctions on Russian refined products. The scheme involving the Kazakh refinery bypasses both of those restrictions.

According to a draft agreement between Russia and Kazakhstan, Condensat will be able to ship the 225,000 tons of gasoline outside the Eurasian Economic Union, a trade bloc that includes both countries and a few other ex-Soviet republics.

Kazakhstan's Energy Ministry confirmed that supplies from Tatneft to Condensat had been agreed at 15,000 tons a month. Russia's Energy Ministry, Tatneft and Condensat have not replied to requests for comment.

Kazakhstan's three main refineries - of which Condensat is not one - are currently barred from exporting gasoline outside the Eurasian Union. (Reporting by Alla Afanasyeva Writing by Olzhas Auyezov Editing by Mark Potter)
