Magnesia Spinel Refractory Blocks from Japan
Magnesia Spinel Refractory Blocks are pre-fired blocks combining magnesia with spinel (MgAl2O4), where the MgO content exceeds 50%, used in cement kiln burning zones. These blocks offer superior thermal spalling resistance and are fired after shaping to achieve the required density. They are classified under 6902.10.00 as refractory ceramic constructional goods with a magnesia content exceeding 50%.

Import Tips
• Provide a certificate of analysis showing the MgO content exceeds 50% to support classification
• Verify that the blocks have been fired after shaping, as per Chapter 69 legal notes
• If the product contains spinel, ensure the alumina content does not affect the classification under 6902.10.00
