Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If niobium-dominant columbite
Niobium-rich tantalite concentrates classify under specific niobium ore subheading 2615.90.
If processing residues containing tantalum
Tantalum extraction tailings or slags fall under Chapter 26 heading 2620 for metal recovery.
If refined tantalum metal unwrought
Purified tantalum beyond ore concentrate stage classifies in Chapter 81 rare metals.
