Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If rare-earth chlorides instead of oxides
Chlorides of rare-earths with yttrium/scandium predominant classify separately under 2846.90.20.30+.
If doped and processed into electronic wafers
Doped silicon or similar cut into discs falls in 3818 per chapter note on electronic forms.
If used in ferroalloys as additive
Ferroscandium or alloy forms shift to Chapter 72 iron/steel.

Import Tips & Compliance
• Require supplier affidavits confirming scandium as predominant metal to avoid reclassification; declare exact composition on entry
• Watch for anti-dumping duties on certain rare-earth oxides from specific origins
