In the Amazon and in the Amapá state, this information is still little known and scarce, and therefore this study was developed to obtain and analyze the volumetric yield coefficient of ten commercial tree species and to test the variation by diameter class. We collect data of volumetric yield from for ten commercial species. For each species, the yields in different diameter classes were analyzed, as well as the yield difference between the species. The overall yield obtained for the sawmills (43.95%) and the yield of each species are within the established standards for operations in the industry according to the legal requirements.  aEnvironmental management  aForest products industry  aSawmilling industry  aFloresta Tropical Úmida  aGestão  aProduto Florestal  aSerraria  aLumber production  aProdução de madeira  aRainforest1 aFERREIRA, R.
