Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cut into discs/wafers
Per chapter note, doped/cut silicon wafers go to 3818; unworked cylinder/rod forms stay in 2845.
If natural silicon
Pure silicon elemental form in 2804; isotopic enrichment for qubits moves to isotope heading.
