HS-6 · Subheading
811231
Hafnium and articles thereof; unwrought, powders, waste and scrap
Heading 8112 — Beryllium, chromium, hafnium, rhenium, thallium, cadmium, germanium, vanadium, gallium, indium and niobium (columbium), articles of these metals, including waste and scrap
Chapter 81: Other base metals
Plain-language overview
Use HS-6 811231 when importing or exporting unwrought hafnium, which includes raw forms like powders and scrap. For instance, if you're shipping hafnium powder for aerospace applications, this code applies.
This code specifically covers hafnium and its articles, distinguishing it from HS-6 811232, which pertains to hafnium alloys. If your product is a pure hafnium metal or powder, 811231 is the correct classification.
Hafnium is primarily used in nuclear reactors and high-temperature applications, making it crucial for industries requiring materials with high melting points. If you're dealing with hafnium waste or scrap, this code also encompasses those items.
When determining the correct HS code, consider the form of hafnium you are dealing with. If your shipment includes hafnium in a different state, such as an alloy with another metal, you may need to look at other subheadings.
