Import Tips
• Verify mineral purity through lab analysis certificates to confirm classification as nepheline syenite vs. synthetic substitutes
• Include geological origin documentation; shipments from Russia or Canada often face specific trade restrictions
• Avoid common pitfall of classifying ground material under Chapter 25 heading 2517 pebbles if particle size exceeds powder specs
