Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If doped for electronic applications and cut into wafers/discs
Chapter notes specify chemically doped elements in wafer/disc form fall under 3818 for semiconductor materials.
If as chemically defined mercury compounds
Subheading note defines 2852.10 for mercury compounds; calcium-mercury amalgams would shift classification.
If further processed into electrical parts
Finished electrical components containing calcium fall under Chapter 85 miscellaneous electrical articles.
