HS Code for Dolomite bricks
View full HS code detailsDolomite bricks are classified under HS code 6815.91. This classification is part of Chapter 68, which covers articles of stone, plaster, cement, asbestos, mica, or similar materials. Specifically, heading 6815 is for articles of stone or other mineral substances not elsewhere specified. Subheading 6815.91 is reserved for articles containing magnesite, magnesia in the form of periclase, dolomite (including in the form of dolime), or chromite. These bricks are typically used in the lining of steel-making furnaces and cement kilns. The classification is driven by the chemical composition of the brick. Unlike ceramic bricks, which are defined by a firing process that creates a vitrified or ceramic bond, dolomite bricks in this category are often chemically bonded or formed from mineral aggregates that do not meet the definition of "ceramics" in Chapter 69.

Common Misclassification
The most frequent misclassification occurs with HS code 6902.10, which covers refractory ceramic bricks containing more than 50% of Mg, Ca, or Cr. The distinction lies in whether the product is truly "ceramic." If the brick is made of mineral substances that have not been fired to the point of ceramic vitrification, or if it is resin-bonded, it belongs in 6815.91. Another error is using 2518.10, which is for raw or calcined dolomite; however, once the material is shaped into a brick, it must be classified as an "article" in Chapter 68 or 69.
