Classification of cement flagstones under HS 6810.19
Cement flagstones are classified under HS code 6810.19 because they are manufactured articles composed of cement, concrete, or artificial stone. This classification falls within Chapter 68, which encompasses articles of stone, plaster, cement, asbestos, mica, or similar materials. Specifically, heading 6810 is designated for articles of cement, concrete, or artificial stone, whether or not reinforced. The subheading 6810.19 is a residual category for tiles, flagstones, and similar articles that do not fall under the specific description of building blocks and bricks, which are categorized under 6810.11. The classification is determined by the material composition and the intended use as a paving or surfacing material. These items are typically pre-cast and cured before being transported to a construction site, distinguishing them from in-situ concrete work. The General Rules of Interpretation (GRI) 1 and 6 are applied here, as the terms of the headings and subheadings provide the most specific description for these finished cement products.

Codes often confused with 6810.19
Common mistake. Cement flagstones are frequently confused with natural stone flagstones, which are classified under HS code 6801.00. The distinction lies entirely in the material; 6801.00 is for natural stone, while 6810.19 is for man-made cement or concrete. Another common error is using 6810.11, which is strictly reserved for building blocks and bricks used in structural wall construction rather than flat paving surfaces.

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).
