HS-6 · Subheading
251820
Dolomite, calcined or sintered; including dolomite roughly trimmed, or merely cut by sawing or otherwise into blocks or slabs of rectangular (including square) shape
Heading 2518 — Dolomite, whether or not calcined or sintered, including dolomite roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape
Chapter 25: Salt; sulphur; earths and stone
Plain-language overview
Use HS-6 251820 when importing or exporting calcined dolomite, which may be shipped as blocks or slabs. For example, a shipment of calcined dolomite slabs used in construction would fall under this code.
This code specifically covers dolomite that has been calcined or sintered, distinguishing it from unprocessed dolomite, which is classified under HS-6 251810. Calcined dolomite is often used in industrial applications, such as in the production of glass or as a flux in steelmaking.
Dolomite that is merely cut into rectangular or square shapes, without any further processing, also falls under this HS-6 line. This contrasts with HS-6 251811, which covers dolomite that is not calcined or sintered.
When classifying dolomite, consider its end-use and processing state. For instance, dolomite used for agricultural lime would not be classified here, as it is not calcined.
