HTS code 2511.10.50.00 classifies imports of: Other. This line sits within Chapter 25 (Salt; sulphur; earths and stone; plastering materials, lime and cement), Section V (Mineral Products), and is catalogued as a tariff line in the USITC 2026 Basic Edition. Duty is calculated against units of quantity: t. Chapter 25 covers a broad category with many neighboring tariff lines, so double-check the classification against the closest matches before filing.

The three duty columns in the table below come directly from the USITC's published Harmonized Tariff Schedule text for this exact line, not a derived or estimated figure. A Special column entry means this line qualifies for preferential treatment: an importer who can document the goods' origin under a covered agreement (USMCA, CAFTA-DR, or one of the bilateral FTAs) applies that rate instead of the General column, so origin documentation is the deciding factor here, not the classification itself. A populated Column 2 only matters for the small set of countries the US does not extend normal trade relations to (currently Cuba and North Korea); it is the pre-WTO "full" statutory rate, not a rate any ordinary importer will encounter.

Beyond the published rate, importers should check for Section 201 safeguards, Section 301 China tariffs, and any active AD/CVD orders that can materially change the real landed cost. Always verify the classification with a licensed customs broker before committing to a supply contract, this page is a research tool, not a customs ruling.
