Import Tips
• Submit detailed petrographic analysis showing nepheline dominance to justify 2529.30 over 2529.21 feldspar
• Label clearly as 'natural blend - not artificially mixed' to distinguish from agglomerated products
• Monitor for silica dust compliance during import handling per OSHA/MSHA standards
