Abstract: The grading quality of tobacco leaves received by cigarette enterprises was analyzed with the data from national supervision of tobacco leaf grading quality at the link of industry/commerce hand-over in 2005.The results indicated that, nationally, the total qualified rate of grading of the received tobacco was 63.4%, over 65%of the tobacco received by 51.4%of the enterprises were recognized as qualified in grading.Concerning the grade of received tobacco, the qualified rate was relatively lower for the tobacco which was higher in price or was received as one lot in large quantities, the qualified rate of middle leaves was obviously lower than that of upper or lower leaves.The main problems in leaf grading were the adulteration with leaves of lower grade resulting in a mix up in stalk positions, grades, and colors.
