HS Code for Unwrought hafnium

Unwrought hafnium is classified under HS code 8112.31. This code is situated within Chapter 81, which covers "Other base metals; cermets; articles thereof." Hafnium is a transition metal often used in nuclear control rods and high-temperature alloys. The classification 8112.31 specifically covers the metal in its primary forms, including powders, as well as waste and scrap. The term "unwrought" refers to hafnium that has been cast into ingots, blocks, or similar shapes but has not been further worked. Because hafnium is chemically similar to zirconium and often occurs with it, precise metallurgical identification is required to ensure it is not classified as a zirconium product. The inclusion of powders and waste in the same subheading as unwrought metal is a specific feature of the 8112.31 classification, differing from many other metal headings.

Products Included

• Hafnium ingots and blocks
• Hafnium powders
• Hafnium waste and scrap
• Hafnium pellets
• Unwrought hafnium alloys

Common Misclassification

Hafnium is sometimes misclassified under HS code 8112.39, which is the category for "other" hafnium products, including semi-finished shapes like plates, sheets, and rods, or finished articles. Another potential error is confusing hafnium with zirconium (HS code 8109), as the two metals are frequently found together in nature. However, if the hafnium content is the primary component or the metal is specifically identified as hafnium, it must remain in 8112.31.

FAQ

What is the HS code for unwrought hafnium?

The HS code for unwrought hafnium, including powders and waste/scrap, is 8112.31.

Does this code include hafnium used in nuclear reactors?

Yes, if the hafnium is in an unwrought form or powder, it is classified here regardless of its intended industrial application.
