8108.90.30 - Articles of titanium

This HTS category, 8108.90.30, encompasses articles manufactured from titanium, excluding those specifically enumerated in preceding subheadings under 8108. The scope is broad, covering a wide array of finished or semi-finished goods where titanium is the principal component by weight or value. This includes items such as fasteners, fittings, tools, and household articles, provided they do not fall into more specific classifications within Chapter 81 or other relevant chapters of the HTS.

At this level, 8108.90.30 serves as a residual classification for titanium articles. It is distinguished from its sibling category, 8108.90.60, which likely covers other types of titanium articles not specifically defined or further subdivided. The primary distinguishing factor between these two "Other" categories at the 8108.90 level would be a further breakdown or exclusion indicated by the official tariff language or subsequent notes.

To provide greater specificity, this category is further subdivided. Subcategory 8108.90.30.30 specifically addresses "Castings" of titanium, indicating articles formed by pouring molten titanium into a mold. Conversely, subcategory 8108.90.30.60 encompasses "Other" articles of titanium that do not qualify as castings, thereby providing a more granular classification for the diverse range of titanium products.
