Import Tips
• Submit lab analysis reports confirming >50% alumina-silica weight to avoid reclassification to lower-duty basic bricks
• Declare intended end-use as refractory construction to differentiate from Chapter 68 millstones or Chapter 69 labware
• Watch for bulk shipments misdeclared as parts; ensure pieces qualify as 'bricks' with standard rectangular dimensions
