HS-4 · 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-4 2518 when importing dolomite, whether it's calcined or not. For example, if you're bringing in blocks of dolomite cut into rectangular shapes for construction, this heading applies. It encompasses both raw and processed forms of dolomite, making it essential for accurate classification.
When deciding between the HS-6 lines, consider the state of the dolomite. HS-6 251810 covers dolomite that is not calcined or sintered, including those simply cut into blocks. If your shipment consists of unprocessed dolomite, this is the appropriate code.
On the other hand, if you're importing dolomite that has been calcined or sintered, you should use HS-6 251820. This line includes dolomite that has undergone heat treatment, which alters its properties and uses, often for more specialized applications in industries like metallurgy or construction.
