Import Tips
• Provide lab analysis reports confirming MgO and carbon percentages; customs often requires this for subheading 6815.99.41.10
• Label clearly as 'unfired resin-bonded' to distinguish from fired products; mislabeling leads to reclassification
• Check for anti-dumping duties on Chinese-origin magnesia carbon refractories
