HS Code for Hafnium metal
Hafnium metal in wrought form is classified under HS code 8112.39. Chapter 81 of the Harmonized Tariff Schedule covers other base metals, cermets, and articles thereof. Heading 8112 specifically includes a group of specialty metals including beryllium, chromium, germanium, vanadium, gallium, hafnium, indium, niobium, rhenium, and thallium. The subheading 8112.39 is reserved for hafnium that has been wrought—meaning it has been worked into shapes like bars, rods, wires, plates, or sheets after the initial smelting or refining process. This classification is based on the chemical identity of the metal and its state of manufacture. Wrought hafnium is often used in specialized industrial applications, such as nuclear control rods or superalloys, due to its high melting point and corrosion resistance. The classification follows General Interpretative Rule 1, as the heading and subheadings specifically name the metal and its physical state. Because it is a base metal not elsewhere specified in Chapters 72 through 80, it falls into the residual metal chapter. The distinction between wrought and unwrought is critical for determining the correct six-digit subheading.

Common Misclassification
Hafnium metal is often misclassified under 8112.31, which is reserved for unwrought hafnium and powders. It may also be confused with 8401.30 if the metal is specifically configured as a nuclear fuel element. Furthermore, zirconium products (8109) are sometimes confused with hafnium due to their chemical similarity and frequent occurrence together in nature.
