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
