Cement, concrete or artificial stone, articles (other than prefabricated structural components for building or civil engineering), whether or not reinforced, n.e.c. in heading no. 6810.
Classification of artificial stone products under HS 6810.99
Artificial stone products are classified under HS code 6810.99. This classification is part of Chapter 68, which encompasses articles of stone, plaster, cement, asbestos, mica, or similar materials. Heading 6810 specifically covers articles of cement, concrete, or artificial stone, whether or not reinforced. Artificial stone is defined in the Explanatory Notes to Chapter 68 as an imitation of natural stone obtained by agglomerating fragments of natural stone or other mineral substances (such as crushed marble, limestone, or quartz) with binders like cement, plastics, or resins. The classification 6810.99 is a residual subheading for "other" articles that are not prefabricated structural components for building or civil engineering (6810.91) and are not tiles or bricks (6810.11/19). Classification is driven by the material composition and the fact that the item is a finished article. The manufacturing process usually involves molding, casting, or pressing the mixture into a specific shape. Because these products are intended for decorative or functional use but do not serve as primary structural building blocks, they fall into this "not elsewhere classified" (n.e.c.) category.

Codes often confused with 6810.99
Common mistake. These products are often confused with HS code 6802, which is reserved for worked monumental or building stone of natural origin. If the stone is quarried and then carved, it belongs in 6802; if it is crushed and rebound, it belongs in 6810. Another common misclassification is 3926.90 (other articles of plastics) when the resin binder content is very high. However, if the mineral character predominates, 6810 is the correct heading. Finally, tiles of artificial stone must be classified under 6810.19 rather than 6810.99.

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).
