8103.20.00.90 - Other

This HTS category, 8103.20.00.90, encompasses unwrought tantalum and articles derived from it that are not specifically classified elsewhere within the 8103.20.00.00 heading. This specifically includes bars and rods that have been produced solely through sintering. The "Other" designation signifies that it serves as a residual category for unwrought tantalum products that do not fit into more specific subheadings.

Crucially, this category distinguishes itself from its sibling, 8103.20.00.30, which is exclusively for tantalum in powder form. While powders are also considered unwrought tantalum, this category captures solid forms of unwrought tantalum, such as ingots, blocks, or granules, as well as sintered bars and rods that have undergone basic processing but have not yet been further fabricated into articles of finished or semi-finished goods. The key distinction lies in the physical form and the extent of processing beyond initial smelting or sintering.
