Last updated: April 2026 dataMarble, travertine, alabaster, and other calcareous monumental or building stones at the block or rough-slab stage are widely traded inputs for the construction, countertop fabrication, and monument industries. Travertine in particular has seen sustained demand in residential and commercial flooring applications, while marble blocks feed both domestic fabrication shops and re-export finishing operations. Classification at this stage depends on the degree of working: material that has been polished, profiled, or cut to non-rectangular shapes is typically classified under finished stone provisions. The distinction between 'calcareous' and non-calcareous stone is a recurring classification question when dealing with mixed-mineral building stones.

Both travertine and marble are calcareous stones and fall within this heading at the rough or block stage. The commercial distinction matters more for finished products, where surface treatment and end-use can affect classification. At the block or rough-slab stage, both are captured here provided they have not been further worked into finished architectural elements.
Alabaster — a fine-grained gypsum or calcite mineral — is explicitly included in this heading alongside marble and travertine when in rough or block form. However, because alabaster is softer and used primarily for decorative carving rather than structural applications, importers should confirm that the specific product's mineral composition and processing state align with this heading's scope before filing entry.
