Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If mixed with other minerals exceeding principal dolomite composition
Chapter note prioritizes heading 2517 for pebbled/graded pebbles, gravel, etc., overriding pure dolomite classification.
If further processed into mosaics, cubes or flagstones
Chapter exclusions send worked marble/dolomite articles to heading 6802, excluding mere rough trimming.
If limestone content exceeds dolomite characteristics
Similar calcareous stones classified by principal mineral; pure limestone falls under 2521.00.
