Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If agglomerated into powder coarser than 0.5mm sieve or semi-manufactured
Powders not meeting the fine powder definition or further processed classify under semi-manufactured forms in 7110.49.
If for iridium oxide or other chemical compounds in powder form
Chemical compounds of precious metals are inorganic chemicals under Chapter 28, not metallic powders of Chapter 71.
If alloyed with other platinum group metals where platinum predominates
Classification follows predominant metal per note 4; platinum-dominant alloys go to 7110.19 unwrought.

Import Tips & Compliance
• Provide sieve test certification proving 90% by weight passes 0.5mm mesh to satisfy subheading note requirements
• Label containers with purity, lot number, and safety data sheets due to pyrophoric risks of fine metal powders
• Avoid common pitfall of misdeclaring as scrap; unwrought powder must be distinguished from waste or used material
