This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If osmium halides or organometallic compounds
Chemical derivatives classify as precious metal compounds in Chapter 28.
If consolidated into bars from powder
Powder consolidated by pressing or melting becomes unwrought bar, still 7110.41 if truly unwrought, but often 7110.49 if worked.
If pre-dispersed in electrical pastes
Articles with precious metal electrical contacts classify in Chapter 85.

Import Tips & Compliance
• Mandatory sieve analysis report from accredited lab to prove powder form qualification
• Special handling required due to osmium's extreme toxicity potential
• Avoid declaring as 'waste'; commercial grade powder must show commercial purity
