6815.91.00.71 - Other

This HTS category, 6815.91.00.71, encompasses "Other" articles made from mineral substances, specifically those containing magnesite, magnesia in the form of periclase, dolomite (including dolime), or chromite, which do not fall under more specific subheadings within the 6815 chapter. These goods are typically characterized by their mineral composition and intended use as articles, rather than raw materials. Examples may include specialized refractory bricks, shapes, or other manufactured items where these minerals are the primary binding or structural components.

This subheading is distinguished from its sibling, 6815.91.00.11, by its broader scope. The sibling category specifically covers articles containing more than 70% magnesia (expressed as MgO) with a carbon content between trace and less than 30%, chemically bonded by resin or pitch. In contrast, 6815.91.00.71 serves as a residual category for other articles meeting the general criteria of containing magnesite, periclase, dolomite, or chromite, but lacking the specific chemical and compositional parameters defined in the sibling. This means articles with different binding agents, lower magnesia content, or varying combinations of the specified minerals would likely fall here.

As a leaf node, this classification does not have further subcategories. Therefore, the practical application of this HTS code relies on a thorough understanding of the specific composition and intended use of the imported or exported article, ensuring it meets the general criteria of being an article of mineral substances containing magnesite, magnesia in the form of periclase, dolomite (including dolime), or chromite, while not being specifically enumerated or defined in a more precise subheading. Careful examination of product specifications and trade documentation is essential for accurate classification.
