HS Code for Unwrought zirconium

Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium. It is classified under HS code 8109.29 when it is in an unwrought form or powder and contains a specific ratio of hafnium. Specifically, this code applies to zirconium containing not less than 1 part hafnium to 500 parts zirconium by weight. This distinction is critical because zirconium and hafnium are often found together in nature and are difficult to separate. Chapter 81 covers "Other base metals," and heading 8109 is dedicated to zirconium. The subheading 8109.29 is used for the "standard" grade of zirconium used in many industrial applications. If the zirconium has a lower hafnium content (less than 1 part per 500), it is classified under 8109.21, which is often referred to as "nuclear grade" zirconium due to its use in nuclear reactors where hafnium's neutron-absorbing properties are undesirable. Unwrought forms include ingots, blocks, and lumps produced by melting or sintering.

Products Included

• Unwrought zirconium ingots (high hafnium)
• Zirconium powders with >0.2% hafnium
• Zirconium lumps and billets
• Primary zirconium slabs
• Zirconium sponge (standard grade)

Common Misclassification

The primary source of misclassification for zirconium is the hafnium content. HS code 8109.21 is specifically for zirconium with a low hafnium content (less than 1 part hafnium to 500 parts zirconium), while 8109.29 is for the standard grade. Misidentifying the grade can lead to significant regulatory issues, especially in the context of dual-use goods and nuclear non-proliferation controls. Furthermore, zirconium waste and scrap should be classified under 8109.31 or 8109.39. Finished articles of zirconium, such as pipes or crucibles, belong in 8109.91 or 8109.99. It is also vital not to confuse metallic zirconium with zirconium silicate (zircon sand), which is classified under 2615.10.

FAQ

What is the HS code for unwrought zirconium?

The HS code for unwrought zirconium (containing at least 1 part hafnium per 500 parts zirconium) is 8109.29.

Why is hafnium content important for zirconium classification?

Hafnium content determines whether the zirconium is classified as "nuclear grade" (8109.21) or "standard grade" (8109.29). Nuclear grade zirconium must have very low hafnium levels to be used in reactor cores.
