White Portland cement is produced from low-iron raw materials and commands a price premium for architectural and decorative concrete applications. At the HTS level, white and gray Portland cements may be classified under different 10-digit lines with distinct duty rates. Importers should confirm the correct subheading based on the product's iron oxide content and intended use, as misclassification between the two is a known audit risk.

Importers should first identify the country of origin and check the USITC and Commerce Department's active antidumping order list for cement. If the origin is covered, a scope ruling request to the Department of Commerce can clarify whether the specific product specification falls within the order. Working with a licensed customs broker experienced in construction materials is strongly recommended before committing to a supply contract.
