Last updated: August 2026 dataWorked limestone and other calcareous building stones beyond marble and travertine are consolidated under this heading, with Italy and Turkey the primary US import sources, followed by Portugal and Morocco. These materials are widely used in facade cladding, flooring, and decorative architectural elements where a softer, warmer aesthetic than granite is preferred. The single 10-digit line 6802920000 covers all worked calcareous stone NESOI, so the classification boundary with 6802.91 (marble and travertine) is the most common point of dispute — particularly for stones marketed under regional trade names that may or may not qualify mineralogically as marble.

No. HTS classification follows the mineralogical composition of the stone, not its commercial trade name. Stones that are technically dense limestone or calcareous sedimentary rock — even if sold as 'marble' in the trade — are classified under the calcareous stone NESOI provisions rather than the marble subheadings. A petrographic analysis can resolve disputes.
Any surface treatment beyond a flat sawn face — polishing, honing, sandblasting, fluting, or edge profiling — constitutes working. Articles cut to specific architectural dimensions with finished surfaces are worked; rough-sawn blanks with only a flat cut surface remain in the simply-cut provisions of 6802.29.
