Dolomite Refractory Bricks from Germany
Refractory bricks derived from fired dolomite with high CaO and MgO content exceeding 50%, used in steel ladles and electric arc furnaces. These provide basic slag resistance essential for secondary steelmaking. HTS 6902.10.50.00 covers these as 'other' high Mg/Ca oxide refractories.

Import Tips
• Test water absorption per ASTM C373 if challenged on ceramic body definition
• Separate from dead-burned magnesite imports which may fall under different chemical headings
• Provide steel industry end-user letters to support refractory classification over general construction goods
