8103 - Tantalum and articles thereof, including waste and scrap:

This section of the Harmonized Tariff Schedule, specifically heading 8103, encompasses pure tantalum and its articles, as well as tantalum waste and scrap. Tantalum is a refractory metal known for its high melting point, corrosion resistance, and ductility, making it valuable in a wide range of industrial applications, including electronics, aerospace, and chemical processing. Articles include finished or semi-finished goods manufactured from tantalum, such as wire, plate, or foil.

Distinguishing this category from its siblings at the same level, such as live animals or other base metals, is straightforward. Heading 8103 is specifically dedicated to tantalum and its related materials, irrespective of their form or whether they are in a raw or processed state. Unlike other base metals that might have broader classifications, this heading is singular in its focus on tantalum.

Within heading 8103, further subdivisions categorize the material based on its form and processing. Subheading 8103.20.00 covers unwrought tantalum, which includes material in the form of powders or bars and rods that have been produced through sintering. This contrasts with waste and scrap, classified under 8103.30.00.00, which refers to discarded or residual tantalum materials suitable for recycling. An "Other" category exists to capture any tantalum articles not specifically provided for in the preceding subheadings.
