Marble, travertine, and alabaster slabs and blocks that have been simply cut or sawn to a flat or even surface — but not yet polished, carved, or otherwise further worked — are the primary raw input for countertop fabricators, tile manufacturers, and monumental stone workshops. The distinction between 'simply cut' and 'further worked' is commercially significant: polished, molded, or decorated articles of the same stones move to a separate heading (66136), often at a different duty rate. Italy and Turkey are globally dominant producers of travertine and marble, and US importers frequently source from both origins. Accurate surface-finish documentation from the quarry or processing facility is essential for correct classification.
