Last updated: July 2026 dataGray Portland cement — the workhorse binder of the US construction industry — is classified under a single 10-digit line (2523290000), and its trade is shaped as much by freight economics as by tariff rates, since cement's low value-to-weight ratio makes ocean shipping cost a natural import barrier. Canada leads US supply by a wide margin given proximity and integrated cross-border logistics, while Turkey and Vietnam serve coastal markets where vessel economics are more favorable. Antidumping duty orders have historically targeted certain cement suppliers, and importers should verify current order scope before contracting with new foreign sources.

White Portland cement (heading 252321) is produced from raw materials with very low iron and manganese content, yielding a white finished product used in architectural and decorative applications. Gray Portland cement under 252329 contains higher iron oxide levels and is the standard structural grade. The distinction is based on the manufacturing process and raw material specification, not simply color; importers should obtain mill certificates confirming the cement type to support classification.
The US has maintained antidumping duty orders on Portland cement from specific countries at various times. Before entering into a supply contract with a new foreign mill, importers should check the current scope of any active AD/CVD orders with the International Trade Administration and confirm whether the prospective supplier has an established individual dumping margin or is subject to the all-others rate. Failure to deposit the correct AD duty at entry can result in significant retroactive liability after administrative review.
