HS code for Wrought hafnium: 8112.39
Hafnium and articles thereof, wrought, other than powders, waste and scrap.
Classification of wrought hafnium under HS 8112.39
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.

Codes often confused with 8112.39
Common mistake. 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).

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
