HS Code for Bentonite clay

Bentonite clay is classified under Harmonized System (HS) code 250810 due to its specific mineralogical composition and natural origin. HS Chapter 25 encompasses "Salt; sulphur; earths and stone; plastering materials, lime and cement." Within this chapter, Heading 2508 is dedicated to "Clays (excluding expanded clays of heading 6806), andalusite, kyanite and sillimanite, whether or not calcined; mullite; chamotte or dinas earths." The subheading 250810 specifically identifies "Bentonite, whether or not calcined." This precise classification reflects bentonite's status as a naturally occurring clay mineral, primarily composed of montmorillonite, and its common forms, including calcined variations. The explicit mention of bentonite within this subheading ensures its accurate and consistent classification for international trade purposes.

Common Misclassification

Common misclassifications for bentonite clay often involve other types of clays or processed clay products. HS code 250830, which covers "Fireclay," is sometimes confused with bentonite. While both are clays, fireclay is characterized by its high refractoriness and different mineralogical composition, primarily kaolinite, whereas bentonite is known for its swelling and binding properties. Another potential misclassification is HS code 250840, designated for "Other clays." This is a residual category for clays not specifically enumerated. Since bentonite is explicitly named in 250810, it should not be classified under this general "other" category. Furthermore, HS code 6806, pertaining to "Expanded clays," represents a distinct processed product used as lightweight aggregates, which is fundamentally different from raw or simply calcined bentonite.

FAQ
