Activated manganese dioxide is a porous form of MnO2 used as a catalyst in organic synthesis and water purification filters. It is classified in HTS 2820.10.00.00 as chemically defined manganese dioxide, activated through thermal or chemical treatment to increase surface area. This distinguishes it from natural pyrolusite.
