Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the powder is pressed into shapes or sintered into semi-finished articles
Powder consolidated into profiles or shapes becomes 'articles' under 8112.99.00 rather than unwrought powders.
If mixed with binders as prepared additives for metal injection molding
Hafnium powder feedstocks with organic binders are chemical preparations under Chapter 38.
If oxidized to hafnium oxide powder
Hafnium oxide (HfO2) is an inorganic compound classified in Chapter 28, not metallic hafnium.

Import Tips & Compliance
• Provide particle size distribution and purity certificates to confirm classification as unwrought powder, not fabricated articles
• Comply with REACH or TSCA chemical registration for fine metal powders due to inhalation health risks
• Package in inert atmosphere containers to prevent oxidation during transit
