Overview

This HTS category, 8112.31.00.00, specifically covers unwrought hafnium, as well as waste and scrap of hafnium, and hafnium in powder form. Unwrought hafnium refers to the metal in its primary, unrefined state, typically cast into ingots, slabs, or other basic shapes before further processing. Waste and scrap encompass discarded hafnium materials or articles of hafnium that are fit only for recovery of the metal or for use in recycling processes. Powders include finely divided hafnium particles.

It is important to distinguish this category from its sibling, 8112.39.00.00, which covers "Other" hafnium articles. While this leaf node focuses on the foundational forms of hafnium (unwrought, waste, scrap, and powder), the sibling category would include manufactured articles made from hafnium, such as semi-finished or finished products, alloys containing hafnium that are not primarily classified elsewhere, or other fabricated items.

As this is a leaf node, there are no further subcategories within 8112.31.00.00. Classification within this code hinges on the material being hafnium and its presentation as unwrought metal, waste or scrap, or powder. The intended use or further processing of these materials is not a primary determinant for classification under this specific code, as long as they meet the physical state criteria.
