Last updated: August 2026 dataCalcareous monumental and building stones not elsewhere specified — including alabaster — occupy a residual classification for limestone-family decorative and structural stones that do not meet the specific definitions of marble, travertine, or other named varieties. Canada is the leading US supplier under this heading, reflecting cross-border trade in limestone and related building materials. Alabaster, a fine-grained gypsum or calcite variety prized for decorative carving, is grouped here and may require careful distinction from gypsum products classified elsewhere in Chapter 25.

Alabaster in this heading refers to the fine-grained calcite or gypsum variety used in decorative and monumental applications, classified here as a calcareous building or monumental stone. Crude or unworked gypsum is separately classified in heading 2520. The key distinction is the intended use and degree of working: alabaster in block or rough form for carving falls here, while industrial gypsum products are classified elsewhere.
Shipments from Canada generally require a commercial invoice, packing list, and bill of lading. To claim USMCA preferential treatment, a certification of origin meeting USMCA requirements must be provided. Because this is an industrial mineral commodity, no special agency admissibility review applies, but accurate stone variety identification on the entry is important to avoid reclassification.
