Within the framework of the semiclassical approximation, we derive the Boltzmann equation describing the dynamics of colourless plasmons in a hot quantum chromodynamics (QCD) plasma. The probability of plasmon-plasmon scattering at the leading order in the coupling constant is obtained. This probability is gauge-independent at least in the class of the covariant and temporal gauges. It is noted that the structure of the scattering kernel possesses important qualitative differences from the corresponding one in the Abelian plasma, in spite of the fact that we focused our study on the colourless soft excitations. It is shown that four-plasmon decay is suppressed by the power of g relative to the process of nonlinear scattering of plasmons by thermal particles at the soft momentum scale. It is stated that the former process becomes important in going to the ultrasoft region of the momentum scale.
