Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods; other than those of siliceous fossil meals or similar siliceous earths
In plain English
This heading covers refractory bricks, blocks, tiles, and similar ceramic construction items, excluding those made from siliceous fossil meals or similar siliceous earths. One category includes these goods if they contain more than half their weight in magnesium, calcium, or chromium oxides. Another category covers items with more than half their weight in alumina, silica, or a mix of these substances. Any other refractory ceramic constructional goods that do not fit these specific chemical compositions fall into the remaining category.
