Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3816.00.20Higher: 38% vs 35%

If optimized for non-steel applications like aluminum melting

Different metallurgical uses may reclassify to other refractory concretes not specified as dolomite ramming.

2523.29.00Same rate: 35%

If imported as separate aggregate components

Individual dolomite aggregates without mixing are Chapter 25 mineral products, not prepared compositions.

3824.99Lower: 15% vs 35%

If with significant organic binding agents

Organic additive-heavy mixes fall under chemical preparations rather than inorganic refractories.
