HTS US: 2507.00.00.00
Description
This heading pertains to kaolin and other kaolinic clays, which are naturally occurring, fine-grained minerals primarily composed of kaolinite. They may be in their natural state or calcined, meaning they have been subjected to heat treatment to alter their physical and chemical properties for industrial uses.
Kaolin and kaolinic clays are widely used in various industries such as paper manufacturing, ceramics, rubber, paints, and pharmaceuticals due to their whiteness, plasticity, and chemical inertness.
Code Hierarchy
- Section II:
- Vegetable Products (Chapters 06-14)
- Chapter 25: Mineral Products
- Heading 2507: Kaolin and other kaolinic clays, whether or not calcined.
- US HTS Code (10-digit):
2507.00.00.00– This code covers kaolin and kaolinic clays in all forms, including calcined varieties.
Detailed Breakdown of Subheadings
Unlike some other HTS codes, heading 2507 is not subdivided into multiple subheadings in the US HTS system; it is generally classified under a single 10-digit code for all kaolin and kaolinic clays. However, understanding the nature and treatment of the material is essential for proper classification.
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2507.00.00.00 | Kaolin and other kaolinic clays, whether or not calcined | Includes raw kaolin, washed kaolin, calcined kaolin, and other processed kaolinic clays used industrially. |
What is NOT Classified Here?
To avoid misclassification, note the following exclusions:
- Other clays such as bentonite or fuller’s earth are classified under different headings (e.g., 2508).
- Kaolin products that are chemically modified or mixed with other substances may fall under different headings depending on composition.
- Processed ceramic products made from kaolin are classified under chapters related to ceramics.
Notes
- Uses and Processing:
- Kaolin can be used in its natural form or calcined by heating to improve brightness and hardness, making it suitable for specialized applications.
- Regulatory Considerations: Importers should verify compliance with environmental and safety regulations, particularly for calcined products that may produce dust or fumes during handling.
- Duty Rates: Duty rates on kaolin and kaolinic clays vary by country of origin and intended use; consult current USHTS and trade agreements.
