Abstract: Polycarbonate resin pellets are disclosed herein. The polycarbonate resin pellets are formed of a polycarbonate resin composition having a melt-flow index (MI) of about 15 g/10 min to about 40 g/10 min as measured at about 250° C. under a load of about 1.2 kgf in accordance with ASTM D1238, wherein the polycarbonate resin pellets have a ratio of an average major diameter to an average minor diameter (average major diameter:average minor diameter) of about 1:0.5 to about 1:1 and a bulk density of about 600 g/cm3 to about 800 g/cm3. The polycarbonate resin pellets can reduce generation of powder chips caused by friction between pellets, thereby reducing appearance defects upon injection molding.
