HS Code for Zirconium powder

HS code 810929 is the specific classification for zirconium powders that contain a significant amount of hafnium. The Harmonized System classifies other base metals in Chapter 81, and heading 8109 is dedicated to zirconium and articles thereof. The structure of this heading distinguishes between unwrought forms (including waste and scrap) and wrought forms (like sheets or pipes). Subheading 8109.29 specifically covers unwrought zirconium and powders, provided they meet the hafnium ratio requirement: containing not less than 1 part hafnium to 500 parts zirconium by weight. This is a critical distinction because high-purity zirconium (with very low hafnium content) is used in nuclear reactors due to its low neutron-absorption cross-section. Such nuclear-grade zirconium is classified under 8109.21. The powder form classified under 8109.29 is often used in non-nuclear applications, such as in the manufacture of vacuum tube getters, specialized alloys, or as a component in pyrotechnic mixtures. The classification depends on both the physical form (powder) and the chemical purity (hafnium content).

Products Included

• Unwrought zirconium powder (high hafnium)
• Zirconium metal powder for pyrotechnics
• Non-nuclear grade zirconium powder
• Zirconium sponge in powder form
• Zirconium grains and granules

Common Misclassification

This code is frequently confused with 810921, which is reserved for zirconium with a hafnium-to-zirconium ratio of less than 1:500 (nuclear grade). It is also confused with 810931, which covers zirconium waste and scrap. Furthermore, zirconium dioxide (the oxide form) should be classified under 282560 rather than the metal powder code.

FAQ

What is the HS code for Zirconium powder?

Zirconium powder with a hafnium content of 1:500 or more is classified under HS code 810929.

What defines "unwrought" zirconium?

Unwrought refers to the metal in its primary form, such as ingots, blocks, or powders, before it has been rolled, forged, or extruded.
