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 drawn into wire, hammered into foil, or other worked forms
Any working beyond casting makes it semi-manufactured osmium under 7110.49.
If imported as osmium compounds or salts
Compounds are classified in Chapter 28 as rare-earth or precious metal chemicals.
If non-monetary gold alloy with osmium where gold ≥2% and no platinum
Gold-dominant alloys (note 5(b)) shift to gold headings even with osmium content.

Import Tips & Compliance
• Include melting point and density verification to confirm osmium identity, as it's the densest natural element
• Comply with toxicity labeling since osmium tetroxide can form from oxidation; provide MSDS
• Watch for alloy thresholds; if ≥2% platinum, reclassifies per Chapter note 5(a)
