Import Tips
• Provide kiln process logs showing low iron raw materials to substantiate white clinker status during customs valuation
• Use moisture-proof bulk bags for clinkers to prevent pre-hydration during ocean transit
• Avoid declaring as finished cement; clinkers have different grinding yield factors affecting duty calculations
