HS Code for Earthenware tiles

Earthenware tiles are classified under HS code 6907.23 based on their material composition and physical properties, specifically their water absorption rate. The Harmonized System organizes ceramic products in Chapter 69, where heading 6907 covers unglazed or glazed ceramic flags and paving, hearth or wall tiles. The subheadings within 6907 are primarily differentiated by the water absorption coefficient by weight. Earthenware is characterized by a relatively high porosity compared to stoneware or porcelain. According to the General Rules for the Interpretation (GRI) of the Harmonized System, products must be classified according to the terms of the headings and any relative section or chapter notes. For ceramic tiles, the water absorption test determines the specific subheading. Since earthenware tiles have a water absorption coefficient exceeding 10%, they fall squarely into 6907.23. This classification applies regardless of whether the tiles are glazed or unglazed, provided they meet the absorption threshold and are not specifically excluded by other subheadings like 6907.30 (mosaic cubes) or 6907.40 (finishing ceramics). The high porosity of earthenware makes it suitable for specific indoor wall applications where weight and moisture breathability are factors, distinguishing it from denser vitrified tiles.

Common Misclassification

Earthenware tiles are frequently misclassified under HS code 6907.21 or 6907.22. Code 6907.21 is reserved for porcelain tiles with a water absorption coefficient not exceeding 0.5%. Code 6907.22 is for stoneware tiles with a water absorption coefficient between 0.5% and 10%. Misclassification often occurs because the visual appearance of a glazed tile can mask its internal porosity. Importers must rely on technical data sheets and lab testing rather than visual inspection to ensure the correct code is applied. Additionally, mosaic tiles are classified under 6907.30 regardless of their absorption rate if they meet the size requirements for mosaics.

FAQ

What is the HS code for Earthenware tiles?

The HS code for earthenware tiles with a water absorption coefficient by weight exceeding 10% is 6907.23.

How is water absorption measured for tile classification?

Water absorption is measured by the increase in mass of a tile after being saturated with water, expressed as a percentage of its dry mass, typically following the ISO 10545-3 standard method.
