HS Code for Industrial clays
Industrial clays are classified under HS code 2508.40. This code is part of Chapter 25, which includes salt, sulfur, earths, stone, plastering materials, lime, and cement. Heading 2508 covers various natural clays, whether or not calcined, but excludes expanded clays. Subheading 2508.40 is the "Other clays" category, encompassing industrial clays that are not kaolin (2507), bentonite (2508.10), fire-clay (2508.30), or andalusite/kyanite (2508.50). These clays are used in a wide range of industrial applications, including the manufacture of ceramics, refractories, paper, and rubber. They are valued for their plasticity, heat resistance, and chemical stability. The classification applies to the clay in its natural state or after it has been washed, ground, or calcined (heated to remove volatile impurities). However, if the clay has been further processed into a finished product or mixed with other materials to form a composite, it may move to Chapter 68 or 69. For customs purposes, it is important to demonstrate that the clay has not been mixed with other minerals in a way that changes its fundamental character as a natural earth. Calcination is permitted under this heading, which is a common process for industrial clays to improve their physical properties for specific manufacturing uses.

Common Misclassification
Industrial clays are often confused with Kaolin (2507.00) or Bentonite (2508.10). Another common error is classifying expanded clays (used for insulation) under 2508.40, whereas they belong in 6806. Clays that have been activated with chemicals for bleaching or filtering purposes are classified under 3802.90.
FAQ
What is the HS code for Industrial clays?
The HS code for industrial clays not elsewhere specified (excluding expanded clays) is 2508.40.
Is calcined clay classified differently?
No, heading 2508 specifically includes clays whether or not they have been calcined, provided they haven't been mixed with other materials.
