Plain-language overview
Use HS-6 251810 when importing or exporting dolomite that has not been calcined or sintered, such as blocks or slabs cut into rectangular shapes. For example, a shipment of dolomite slabs used in construction would fall under this code.
This HS-6 line specifically covers dolomite that is roughly trimmed or cut, distinguishing it from HS-6 251820, which pertains to calcined dolomite. If your product has undergone any calcination process, you would need to classify it under that separate code.
Dolomite in this category is often used in construction, landscaping, and as a raw material in various industrial applications. It's essential to ensure that the dolomite is not processed in any way that would change its classification.
When preparing your shipment, be clear about the product's form and intended use. This will help customs officials accurately classify your goods and avoid delays.
