Other refractory ceramic items containing less than 45% aluminium oxide and more than 50% aluminium oxide–silica mixture or compound

This is a complete 8-digit customs code. There is no further code choice to make below it.

This covers refractory ceramic retorts, crucibles, muffles, nozzles, plugs, tubes, rods and other similar items, excluding refractory bricks, blocks, tiles and similar construction materials. The item must contain less than 45% by weight aluminium oxide (Al2O3) and more than 50% by weight of a mixture or compound of aluminium oxide (Al2O3) and silica (SiO2).

For example

A refractory ceramic crucible containing less than 45% by weight aluminium oxide and more than 50% by weight of an aluminium oxide–silica mixture or compound
A refractory ceramic tube containing less than 45% by weight aluminium oxide and more than 50% by weight of an aluminium oxide–silica mixture or compound
A refractory ceramic nozzle containing less than 45% by weight aluminium oxide and more than 50% by weight of an aluminium oxide–silica mixture or compound
