Product classification
HS code for Worked slate: 6803.00
Slate, worked, and articles of slate or of agglomerated slate.
Classification of worked slate under HS 6803.00
Worked slate and articles made of slate are classified under HS code 6803.00. This heading covers slate that has been further processed than the basic extraction and rough splitting described in Chapter 25. For a product to fall under 6803.00, it must be worked—meaning it has been cut, sawn, polished, or otherwise shaped into specific articles. Slate is a natural stone characterized by its ability to be split into thin sheets, and when these sheets are prepared for use in construction or as finished goods, they move from the mineral category (Chapter 25) to the stone articles category (Chapter 68). This code also includes articles made of agglomerated slate, which is produced from slate powder or waste bonded with a binder. The classification is straightforward as 6803.00 is a single heading that does not have further sub-divisions in the standard international HS nomenclature, though national tariffs may add specific digits for roofing slates versus other items.

Codes often confused with 6803.00
Common mistake. The most common misclassification is with HS code 2514.00, which covers slate that is unworked or merely roughly trimmed or squared by sawing. If the slate has been precisely cut to size or polished, it must be moved to 6803.00. Additionally, slate articles are sometimes confused with other worked stones in heading 6802 (like granite or marble), but 6803.00 is specific to slate due to its unique geological properties and traditional uses.

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).
