Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If doped for electronics and cut into wafers or discs
Doped chemical elements in worked forms like wafers fall under heading 3818 per chapter note.
If in the form of anhydrous boric acid
Boric acid (H3BO3) is classified as a boron oxide compound under 2840, not elemental boron.
If chemically defined mixtures containing boron
Mixed preparations with additives exceed pure elemental classification and go to 3824.
