Magnesia Carbon Building Bricks from Germany
High-performance building bricks composed of over 70% magnesia (MgO) with carbon content under 30%, chemically bonded using resin or pitch. These bricks are designed for extreme heat resistance in industrial construction like furnace linings. They fall under HTS 6810.11.00.10 due to their specific magnesia-carbon composition and bonding method.

Import Tips
• Verify chemical composition certificates showing >70% MgO and <30% carbon to confirm classification under 6810.11.00.10
• Provide bonding agent details (resin or pitch) in documentation to avoid misclassification as ceramic products
• Ensure bricks meet building code standards; common pitfall is incorrect declaration of carbon content leading to duty reassessment
