HS code for Ceramic floor blocks: 6904.90

Ceramic flooring blocks, supports or filler tiles and the like (excluding building bricks).

Classification of ceramic floor blocks under HS 6904.90

Ceramic floor blocks are classified under heading 6904, which covers ceramic building bricks, flooring blocks, support or filler tiles, and the like. Subheading 6904.90 specifically addresses flooring blocks and filler tiles that are used in the structural assembly of floors and ceilings. These are distinct from decorative surface tiles. The classification is based on the structural application of the product within the construction industry. These blocks are often hollow and designed to be used in conjunction with reinforced concrete beams to create lightweight, fire-resistant floor systems. The HS code 6904.90 excludes building bricks (6904.10) and also excludes ceramic flags and paving tiles (6907), which are intended for surface finishing rather than structural support. The material must be ceramic, typically fired clay, to meet the requirements of this chapter. The classification remains in 6904.90 regardless of whether the blocks are glazed or unglazed, provided their primary function is structural or as a filler in floor construction.

Codes often confused with 6904.90

Common mistake. The most common misclassification is under heading 6907, which covers ceramic flags and paving, hearth, or wall tiles. The distinction is that 6907 items are surface finishes, while 6904.90 items are structural components. Another error is using 6904.10, which is strictly for building bricks used in walls. Importers must ensure the product is identified as a flooring or filler block to use 6904.90.

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).
