HTS code 2515 classifies imports of: Marble, travertine and other calcareous monumental or building stone of an apparent specific gravity of 2.5 or more, and alabaster, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape:. 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 heading in the USITC 2026 Basic Edition. The schedule specifies ad valorem (percentage-of-value) duty for this line. Chapter 25 covers a broad category with many neighboring tariff lines, so double-check the classification against the closest matches before filing.

The general (MFN / Column 1 General) rate for HTS 2515 is Free, which applies to most trading partners of the United States. No special preferential rate is listed for this line, so FTA origin alone will not reduce the general duty. Because the general rate is Free, most imports under this code enter the US without duty, though anti-dumping, countervailing, or Section 301 tariffs can still apply depending on country of origin.

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.
