Type I Portland Cement
Type I Portland cement is a general-purpose hydraulic cement produced by grinding clinker with gypsum, suitable for a wide range of construction applications like buildings and bridges. It falls under HTS 2523.29.00.00 as 'other' Portland cement, not specifically the white or low-alkali variants. This classification covers standard gray Portland cement meeting ASTM C150 specifications.
Type II Portland Cement
Type II Portland cement is moderately sulfate-resistant and suitable for structures exposed to moderate sulfate action or seawater, made from clinker with controlled C3A content. Classified under HTS 2523.29.00.00 as 'other' Portland cement, it excludes specialized types like white or oil-well cements. Ideal for dams, culverts, and marine applications.
Type V Portland Cement
Type V Portland cement offers high sulfate resistance for severe exposure conditions like sewage treatment plants and sulfate-rich soils, with very low tricalcium aluminate. It is categorized under HTS 2523.29.00.00 as other Portland cement, distinct from white or special-use cements. Essential for aggressive environmental concrete applications.
General Use Portland Cement GU
General Use (GU) Portland cement, equivalent to Type I/II blend, is versatile for most concrete works including residential and commercial buildings. Under HTS 2523.29.00.00 as other Portland cement, it covers standard multi-purpose gray hydraulic cements not fitting specific subheadings. Widely used in ready-mix concrete production.
Ordinary Portland Cement OPC 43 Grade
OPC 43 Grade is Ordinary Portland Cement with minimum compressive strength of 43 MPa at 28 days, used for general construction like pavements and mass concrete. Classified in HTS 2523.29.00.00 as other Portland cement, encompassing standard strength grades. Common in emerging markets for infrastructure projects.
Type IL Portland-Limestone Cement
Type IL Portland-limestone cement contains up to 15% limestone interground with clinker, offering similar performance to traditional Portland with lower CO2 footprint. It qualifies under HTS 2523.29.00.00 as other Portland cement since limestone is a permitted addition. Used increasingly for sustainable concrete mixes.
