HS Code for Wrought hafnium

Wrought hafnium is classified under HS code 8112.39. This code is reserved for hafnium and articles made from it that have been subjected to mechanical working. The "wrought" designation covers products like bars, rods, wire, and sheets that have been produced through rolling, extrusion, or similar processes. Hafnium is often used in specialized applications such as nuclear control rods or superalloys, and its classification under 8112.39 ensures it is distinguished from raw hafnium sponges, ingots, or powders. The classification process involves identifying the base metal and then determining the level of processing it has undergone, as per the Explanatory Notes to Chapter 81. If the hafnium has been shaped into a specific industrial form or a finished article, it falls under this subheading. This classification is critical for regulatory compliance, especially given hafnium's dual-use nature in both civilian and military nuclear technology. The code also encompasses hafnium alloys where hafnium is the primary constituent by weight.

Products Included

• Hafnium bars and rods for nuclear reactor control
• Hafnium wire used in plasma cutting tips
• Hafnium plates and sheets
• Hafnium foil and strip
• Hafnium tubes and pipes
• Finished articles made of hafnium

Common Misclassification

Hafnium is frequently misclassified under HS code 8112.31, which is the code for unwrought hafnium, powders, waste, and scrap. If the metal has been worked into a rod or wire, 8112.39 must be used. Additionally, hafnium is often confused with zirconium (HS code 8109) because they are chemically similar and often occur together. However, they must be classified separately based on which metal predominates. Another error is classifying hafnium oxide under this code; oxides belong in Chapter 28 (2825.90).
