White Supersulfate Cement from China
White supersulfate cement combining Portland clinker with high sulfate content for sulfate resistance, maintaining white colour through low-iron components. Although supersulfate cement is generally in heading 25.23, tariff item 2523.21.00 specifically covers white cement, and this product's white hydraulic nature qualifies it here.

Import Tips
• Verify the product is not a dolomite ramming mix or other excluded product under Chapter 25 Note 2
• Provide sulfate content and whiteness data to support classification under white cement rather than other hydraulic cements
