COMPASS, a fixed target experiment on the SPS M2 beamline at CERN, has started to collect physics data from Autumn 2002 on a polarized 6LiD target. This target can be both longitudinally and transversely polarized with respect to the polarized 160 GeV/c beam. In 2002, 2003 and 2004, 20% of the beam-time was spent in the transverse configuration, allowing the measurement of transverse spin effects. Here the results for the Collins and Sivers asymmetries for charged hadrons, extracted from the 2003–2004 data are presented.
