Oxidizers are materials that can provide oxygen or increase the oxygen content in the air, making other materials more susceptible to burning or combusting.
Organic peroxides, as you mentioned, are a specific type of oxidizer that are derived from hydrogen peroxide, where one or both of the hydrogen atoms have been replaced with an organic group. Organic peroxides are particularly dangerous because they are highly reactive and can easily decompose, releasing heat and potentially leading to a fire or explosion.

Reason for Regulation
Oxidizers are not necessarily combustible materials themselves, but they can provide oxygen or increase the oxygen content in the air, making other materials more susceptible to burning or combusting. This can make it difficult to control a fire once it starts and can lead to an acceleration of the fire and an increase in the heat release rate, which can be extremely dangerous.
