In this paper it was studied the Eucalyptus grandis taper in order to determinate the volume and formation of wood assortment in two classes: sawmill, consisting of logs with 30 cm minimun diameter overbark and lenght of 4,20m, 3,40m and 2,60m, with priority of getting higher sizes groups; industrial logs or segments of it, with diameter between 7cm and 30cm overbark. The taper was adjusted by a 5 degree polynomial, having as dependent variable the relative diameter (di/d) and as independent variable the relative height (hi/h), which showed good adjustment and good statistical precision. This result shows the possibility of estimating either the absolute and relative volume of the assorment by integration of the taper function.
