6909.19 - Other:

This category encompasses ceramic wares specifically designed for laboratory, chemical, or other technical applications. These articles are characterized by their specialized properties, such as chemical resistance, thermal stability, or electrical insulation, making them suitable for demanding industrial or scientific environments. Examples include crucibles, beakers, filtering apparatus, and insulating components where such specific technical functionalities are paramount.

It is important to distinguish this category from its siblings. While Section 69 broadly covers ceramic products, Heading 6909 focuses on those with technical or industrial uses. Unlike goods classified under 6909.11, which specifically details wares made of porcelain or china, this broader category encompasses technical ceramic articles made from a wider range of ceramic materials. Furthermore, it is distinct from 6909.12, which is reserved for articles with a Mohs hardness of 9 or greater, focusing instead on the functional technical application of the ceramic ware.

Within this heading, further subdivisions exist to refine classification based on specific types of technical ceramic articles. The subcategories, such as "Ferrite core memories" (6909.19.10.00) and "Other" (6909.19.50), allow for the granular categorization of specialized technical ceramic components. This ensures accurate tariff treatment for diverse items ranging from electronic components to specialized industrial parts.
