Import Tips
• Provide detailed chemical breakdown (CaO, Al2O3 content) to distinguish from aluminous cement variants
• Ensure bulk packaging complies with IMO hazardous materials regs if shipped in large quantities
• Avoid common pitfall of declaring as 'Portland-type' which triggers different duty and testing requirements
