Product classification
HS code for Curbstones: 6801.00
Stone, setts, curbstones and flagstones, of natural stone (except slate).
Classification of curbstones under HS 6801.00
Curbstones of natural stone are classified under HS code 6801.00. This classification is based on the product's identity as a stone sett, curbstone, or flagstone used primarily for paving or bordering roads and walkways. Chapter 68 covers articles of stone, plaster, cement, asbestos, mica, or similar materials. The specific heading 6801 is dedicated to natural stone (excluding slate) that has been shaped for these specific infrastructure purposes. The classification depends on the stone being "natural" rather than artificial or agglomerated. The processing involved—usually sawing or cleaving into specific rectangular or curved shapes—is consistent with the requirements of this heading, provided the stone has not been further worked into monumental or building stone which would fall under a different category.

Codes often confused with 6801.00
Common mistake. Curbstones are often misclassified under HS code 6802.93 or 6802.99, which cover worked monumental or building stone. While curbstones are technically "worked," HS code 6801.00 is more specific for stones intended for paving and bordering. Another common error is using HS code 6810.11 or 6810.91, which are for articles of cement or concrete. If the curbstone is made of pre-cast concrete rather than natural quarried stone, it must be classified in Chapter 6810. Finally, slate curbstones are excluded from 6801 and must be classified under HS code 6803.00.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
