HS code for Slate roofing: 6803.00
Slate, worked, and articles of slate or of agglomerated slate.
Classification of slate roofing under HS 6803.00
Slate roofing is classified under HS code 6803.00 because it represents a finished article of natural stone that has undergone significant working beyond simple extraction or rough trimming. According to the General Rules of Interpretation (GRI), products are classified based on their state of manufacture. While raw slate belongs in Chapter 25, slate that has been split, cut to specific sizes for roofing, or otherwise shaped into tiles falls into Chapter 68, which covers articles of stone, plaster, cement, or similar materials. Specifically, 6803.00 covers worked slate and articles of slate or of agglomerated slate. For roofing purposes, these tiles are typically rectangular but may be shaped or pre-drilled for installation, which confirms their status as finished building materials rather than raw mineral products.

Codes often confused with 6803.00
Common mistake. The most frequent misclassification occurs with HS code 2514.00. This code is reserved for slate that is in its crude state, roughly trimmed, or merely cut by sawing into blocks or slabs. If the slate has been further worked into a specific roofing shape or has had its edges finished, it must be moved to 6803.00. Additionally, ceramic roofing tiles (6905.10) and concrete roofing tiles (6810.19) are often confused with natural slate, but these are distinguished by their material composition rather than their function.

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).
