The drying quality of kiln dried timber was verified in Polish sawmills and furniture companies. The estimation of the quality was limited to the mean moisture content after drying. The quality classes specified in the European Drying Group Recommendation were primary used in the analysis. The obtained results showed that sawmills might presently satisfy the S quality class, while the furniture companies might achieve the Q class. The better kiln drying quality may be obtained in sawmills after introducing improved procedures of timber stacking and kiln loading.
