Import Tips
• Request supplier certifications for iron oxide (Fe2O3) below 0.5% to match ceramic grade specs and avoid disputes
• Use ISPM-15 compliant wooden pallets for bulk shipments to prevent fumigation holds at entry
• Maintain chain-of-custody records from mine to port to prove no chemical fluxing occurred
