Slate enters US commerce under a single tariff line (2514000000) covering the stone in its raw or minimally processed state — crude, roughly trimmed, or merely cut by sawing into rectangular or square blocks or slabs. Its fine-grained, foliated structure makes it a preferred material for roofing, flooring, and cladding applications where natural cleft surfaces are valued. China and India dominate US imports, with Brazil, Spain, and Portugal also among the leading source countries.
