The objective of this study was to examine the evolution of wood assortment in Pinus taeda stands, located in Parana state. 144 trees were sampled in three site classes and complete stem analysis was applied. The average assortment volumes per tree were obtained in all age classes and sites. 7-9 year age classes predominantly contain volumes adequate for pulpwood. In 10-12 year classes larger volumes were obtained for sawnwood, with 51.09%, 47.63% and 37.89% of the total volume, respectively for sites I, II and III. Volumes for veneer are produced in the 13-15 year classes, representing 43.98 and 25.46% of total volume for sites I and II. Volumes for sliced veneer are produced in the 16-18 year classes with 30.8% and 14.85% of the total volume for sites I and II. Best sites produce larger logs sooner, suggesting that site has influences on wood assortment. Assortment dynamics also shows a change in the forest assortment after 13th year. This way, harvests after this age should be carefully analyzed, considering that anticipation of a few months or a year in cutting of the trees can make an important economic difference.
