Magnesia-Dolomite Composite Refractory Blocks from China
Magnesia-Dolomite Composite Refractory Blocks are composite blocks blending magnesia and dead-burned dolomite, achieving a combined MgO and CaO content exceeding 50% for basic oxygen furnace linings. These blocks are fired after shaping to provide balanced chemistry for steelmaking slags and high-temperature resistance. They are classified under 6902.10.00 as refractory ceramic constructional goods containing more than 50% of MgO or CaO.

Import Tips
• Document the combined MgO and CaO content to confirm it exceeds 50% by weight
• Ensure the blocks are fired after shaping, as per Chapter 69 requirements
• Check if the product contains any excisable goods, as statistical note 1 may apply to certain classification numbers
