Last updated: August 2026 dataCrude and roughly trimmed slate enters the US under a single tariff line (2514000000), making origin and processing stage the key classification checkpoints. In the construction and roofing sectors, this raw form is distinguished from worked or finished slate products, which fall under separate headings. China and India dominate US supply, with Brazil, Spain, and Portugal rounding out the leading source countries. Importers should confirm that surface treatment or splitting does not push material into a more-processed classification before shipment.

Roughly trimmed slate has undergone only basic shaping to facilitate transport or handling — it has not been sawn, split to thickness, or surface-finished. Once slate is cut to specific dimensions, polished, or otherwise worked beyond rough trimming, it typically moves into a different HTS heading covering worked monumental or building stone.
Imports of slate from China may be subject to Section 301 tariffs. Importers should verify the current Section 301 list status for this HTS line before finalizing landed-cost calculations, as applicability and rates can change.
