Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If higher magnesia content (>70%)
Predominantly magnesia mixes shift to general refractory compositions outside dolomite-specific subheading.
If precast into patching blocks
Formed shapes become Chapter 69 refractory goods rather than ramming mixes.
If pure calcium or magnesium oxide components
Separate chemical oxides without refractory mixing are inorganic compounds in Chapter 28.
