6909.11 - Of porcelain or china:

This HTS category, 6909.11, specifically covers ceramic wares designed for laboratory, chemical, or other technical applications, made from porcelain or china. These items are characterized by their specialized nature, intended for use in environments requiring resistance to chemical reactions, high temperatures, or precise measurements. Examples include crucibles, evaporating dishes, filter funnels, and laboratory apparatus constructed from porcelain or china, where their inherent material properties are critical for their function.

This subcategory, "Of porcelain or china," differentiates itself from its sibling, 6909.12.00.00, which pertains to ceramic articles with a Mohs hardness of 9 or more. While some porcelain items may meet this hardness criterion, 6909.11 focuses on the technical application and material composition of porcelain or china, irrespective of the specific Mohs hardness rating, as long as they are intended for laboratory or technical use. Similarly, it is distinct from the broader "Other" category (6909.19) which would encompass technical ceramic wares not made of porcelain or china.

Further subdivisions within 6909.11 exist to provide more granular classification. The subcategories 6909.11.20.00 (Machinery parts) and 6909.11.40.00 (Other) allow for the specific identification of porcelain or china components used in machinery, separate from other technical ceramic wares. This distinction aids in tracking specific types of imported goods and applying relevant trade statistics or regulations.
