The present invention provides a method for producing a masterbatch and related products which enhance the dispersibility of fillers in rubber to improve rubber physical properties such as tensile strength, rigidity, and fuel economy. Provided is a method for producing a masterbatch, including: step (1) of mixing a rubber latex having a zeta potential of -100 to -20 mV with a filler dispersion having a zeta potential of -90 to -10 mV to prepare a latex compound; and step (2) of adjusting a zeta potential of the latex compound prepared in step (1) to -30 to 0 mV.
