This study has aimed to investigate production of neutral sulfite semi-chemical (NSSC) pulping from eucalyptus camaldulensis in Zabol, Sistan & Balouchestan, Iran. Chemical composition including cellulose, lignin, extractive and ash were measured (48.33%), (28.49%), (5.94%) & (0.65%) respectively, while dimension of fibers including length (0.935mm), diameter (19.13μm), lumen cavity (8.89μm) & cell wall thickness (5.12μm). Cooking conditions were consist of three levels of chemical charge (10, 14 & 18% on O.D weight), constant time of 90min, constant temperature of 170 °C & liquor to wood ratio of 7:1. The pulps were refined to 400±25mL, CSF & 127gm-2 hand sheets were made. Finally, strength properties of the pulps were compared and evaluated with that of Mazandaran Wood and Paper Industries (MWPI), Iran. The results showed that pulp yield decreases with increase of chemical charge. Analysis of the mechanical properties indicated that the paper from NSSC of eucalyptus at various cooking levels has preference of NSSC pulp of
