A test method for determination of organotin compounds in paint film by GC-MS was developed.Organotin compounds in paint film were extracted by Ultrasonic extraction with ethanol,then the extracts were derived with tetraethyl of boron sodium,and then the derivatives were tested by GC-MS.The regression coefficients（r） of the organotin derivatives were over 0.999.The recoveries and RSD varied in the range of 90 %~110 % and 2.7 %~6.7 % respectively.This method was suitable for determining organotin compounds in paint film.
