Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in matte or intermediate form
Matte or semi-processed cobalt products shift to earlier subheading before final articles.
If used in jewelry or as silversmith articles
Cobalt articles for ornamental purposes fall under Chapter 71 for base metal jewelry.
If insulated for electrical conduction
Insulated cobalt wire becomes an electrical conductor under Chapter 85, not pure metal article.

Import Tips & Compliance
• Verify cobalt purity exceeds 99% by weight per Chapter 81 notes to avoid reclassification as alloys
• Provide mill test certificates documenting chemical composition to Customs for smooth clearance
• Beware of scrap mislabeling; pure wire cannot include waste under this code
