HS Code 38151910 - copper bismuth oxide catalysts
Catalysts in the form of grains of which >= 90% by weight have a particle-size <= 10 micrometres, consisting of a mixture of oxides on a magnesium-silicate support, containing by weight >= 20% but <= 35% of copper and >= 2% but <= 3% of bismuth and of an apparent specific gravity of >= 0,2 but <= 1,0
Examples (No official information or warranty)
