HS code for Slate tiles: 6803.00
Slate, worked, and articles of slate or of agglomerated slate.
Classification of slate tiles under HS 6803.00
Slate tiles are classified under HS code 6803.00 because they represent worked slate that has been processed beyond the state of simple quarrying. In the Harmonized System, raw minerals and stones are typically found in Section V, specifically Chapter 25. However, once a stone like slate has been subjected to processes such as polishing, chamfering, or being shaped into specific articles like tiles, it moves to Chapter 68. This chapter covers articles of stone, plaster, cement, and similar materials. Heading 6803 is dedicated exclusively to worked slate and articles made of slate or agglomerated slate. The classification depends on the degree of processing; if the slate is merely split or roughly squared, it remains in Chapter 25. Once it is further processed into a finished or semi-finished building material like a floor or roof tile, 6803.00 becomes the mandatory classification. This code encompasses both natural slate that has been worked and articles made from slate dust or fragments that have been reconstituted with a binder.

Codes often confused with 6803.00
Common mistake. Slate tiles are frequently confused with HS code 2514.00, which covers slate that is unworked or merely roughly trimmed or squared by sawing. The distinction lies in the level of finishing; if the tile has been polished or cut to a specific final shape for installation, it must be moved to 6803.00. Additionally, they are sometimes misclassified under 6802, which covers other worked monumental or building stones like granite or marble. However, because slate has its own specific heading in 6803, General Interpretative Rule 1 requires it to be classified there rather than the more general 6802.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
