Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-6 · Subheading
810921
Zirconium; unwrought, powders, containing less than 1 part hafnium to 500 parts zirconium by weight
Heading 8109 — Zirconium; articles thereof, including waste and scrap
Chapter 81: Other base metals
Plain-language overview
Use HS-6 810921 when importing or exporting unwrought zirconium powders that contain less than 1 part hafnium to 500 parts zirconium by weight. For example, if you're shipping a batch of zirconium powder used in specialized metal alloys, this is the correct code.
This HS-6 line specifically covers zirconium in its unwrought form, distinguishing it from other forms like zirconium scrap or articles made from zirconium. If you're dealing with zirconium articles or waste, you would need to look at different codes under the same heading.
Zirconium powders classified under this code are often used in high-temperature applications, such as in nuclear reactors or aerospace components, due to their excellent corrosion resistance. It's important to ensure that your product meets the hafnium content requirement to avoid misclassification.
When comparing with HS-6 810922, which covers zirconium powders with a higher hafnium content, make sure to verify the exact composition of your product. Misclassification can lead to delays or additional duties.

- What types of products are covered under HS-6 810921?
- HS-6 810921 covers unwrought zirconium powders with less than 1 part hafnium to 500 parts zirconium by weight, typically used in high-performance applications.
- How can I check the hafnium content in my zirconium powder?
- You can check the hafnium content through laboratory analysis or certification from your supplier to ensure it meets the requirements for HS-6 810921.
- Can I use this code for zirconium articles?
- No, HS-6 810921 specifically applies to unwrought zirconium powders. For zirconium articles, you would need to look at different codes under the same heading.
- What should I do if my zirconium powder has more hafnium than allowed?
- If your zirconium powder exceeds the hafnium limit, you will need to classify it under HS-6 810922 or another appropriate code based on its composition.
- Are there specific regulations for shipping zirconium powders?
- Yes, shipping zirconium powders may be subject to specific regulations depending on the destination country, especially for applications in nuclear or aerospace industries.
- What are common uses for zirconium powder classified under this code?
- Common uses include aerospace components, nuclear reactor parts, and specialty alloys due to zirconium's excellent corrosion resistance and high-temperature stability.
- How do I ensure compliance when importing zirconium powders?
- Ensure compliance by verifying the hafnium content, obtaining proper documentation, and consulting with a customs broker familiar with HS codes related to zirconium.
- What happens if I misclassify my zirconium product?
- Misclassification can lead to delays, fines, or additional duties, so it's important to accurately classify your product based on its composition and intended use.
