2619.00.30.00 - Ferrous scale

This HTS category, 2619.00.30.00, specifically covers "Ferrous scale." Ferrous scale refers to the thin, flaky layer of iron oxide that forms on the surface of iron or steel during hot working processes such as rolling, forging, or heat treating. This scale is a byproduct of steel manufacturing and is typically collected as a waste material.

This classification is distinct from its sibling category, 2619.00.90.00, which covers "Other" slag, dross, scalings, and waste from iron and steel manufacturing. While both categories fall under the broader heading of waste materials from iron and steel production, 2619.00.30.00 is a precise designation for the specific material known as ferrous scale. Other wastes, such as ash, residues, or granulated slag, would be classified under the "Other" heading.

As a leaf node within the HTS structure, 2619.00.30.00 does not have further subcategories. Therefore, classification within this code relies on the accurate identification of the material as ferrous scale, based on its origin in iron or steel manufacturing and its characteristic physical form as a scale or flaky oxide layer.
