Magnesia-Chrome Refractory Brick from China
Magnesia-chrome refractory bricks are fired ceramic blocks made from magnesia and chromite for superior resistance to basic slags in steelmaking furnaces. They maintain structural integrity at temperatures exceeding 1700°C. This product fits HTS 6902.90.50.20 as 'other' refractory ceramic constructional goods, distinct from siliceous types.

Import Tips
• Include laboratory analysis reports confirming magnesia content and post-firing properties to support refractory classification
• Ensure bricks are not pre-assembled into shapes that might classify as parts under 6903 or 6904
• Beware of environmental regulations on chrome content; prepare REACH-like documentation for U.S. entry
