Plain-language overview
Use HS-6 250870 when importing or exporting clays, specifically chamotte or dinas earths. For example, if you're shipping a bulk order of chamotte used in refractory materials, this is the correct code.
This subheading focuses on clays that are not expanded, distinguishing them from other types like expanded clays classified under heading 6806. If you're dealing with products like kaolin or bentonite, those would fall under different HS codes.
The HS-6 250870 line specifically covers chamotte or dinas earths, which are used primarily in high-temperature applications such as furnace linings. This is different from other clays that may be used for ceramics or construction.
If you are unsure whether your clay product fits under this code, consider its end use. For instance, if it’s intended for making bricks or tiles, it might belong to a different classification.
