Import Tips
• Submit mill test certificates detailing Al2O3 percentage and refractoriness-under-load specs for CBP verification
• Differentiate from parts of machinery (84/85 chapters) by emphasizing standalone constructional use
• Beware anti-dumping duties on certain Chinese alumina refractories; check Commerce Dept. scopes
