6914.90 - Other:

This HTS category, 6914.90, encompasses "Other" ceramic articles not specifically enumerated in prior headings within Chapter 69. It serves as a residual category for ceramic products that do not fall under more specialized classifications, such as those made of porcelain or china (6914.10). The scope of this heading is broad, covering a wide array of ceramic items based on their material composition and intended use, provided they are not otherwise classified.

When classifying an article under 6914.90, it is crucial to first exhaust all other possible classifications within Chapter 69. If a ceramic article does not fit more specific descriptions, such as sanitary ware, tableware, or electrical insulators, it may be classified here. This residual nature means the specific items can vary widely, from technical ceramics to decorative objects, as long as they are predominantly made of ceramic materials and do not meet the criteria for more narrowly defined categories.

The subcategories within 6914.90 further refine the classification of these residual ceramic articles. For instance, 6914.90.41.00 specifically addresses certain ceramic ferrules and mating sleeves made of alumina or zirconia with precise dimensional and functional characteristics, primarily used in fiber optic applications. The remaining "Other" subcategory, 6914.90.80.00, is for all other ceramic articles that do not meet the specific criteria of the more detailed subcategories, maintaining the residual function of the parent heading.
