HS Code for Slate blocks

Slate blocks are classified under HS code 2514.00. This heading covers slate in its natural state, whether or not it has been roughly trimmed or merely cut by sawing or other means into blocks or slabs of a rectangular or square shape. The classification is determined by the level of processing; the stone must not have reached the stage of being "worked" stone. If the slate has been further processed—for example, by being polished, chamfered, or shaped into specific items like roofing tiles—it would move to Chapter 68. Heading 2514 is strictly for the raw or minimally processed mineral material intended for further industrial or architectural use. The Harmonized System distinguishes between raw mineral products (Chapter 25) and articles made of stone (Chapter 68) based on the degree of finishing and shaping.

Common Misclassification

Slate blocks are most commonly misclassified under 6803.00, which covers worked slate and articles of slate, such as finished roofing shingles or billiard table tops. They may also be confused with 2515.11 (marble blocks) or 2516.11 (granite blocks) if the geological nature of the stone is not correctly identified by the importer.
