6909.11.20.00 - Machinery parts

This HTS category, 6909.11.20.00, specifically covers ceramic wares made of porcelain or china that are intended for laboratory, chemical, or other technical uses. These items are engineered for demanding environments where resistance to heat, corrosion, and chemical reactions is paramount. Examples include crucibles, evaporating dishes, beakers, flasks, and filtering apparatus constructed from porcelain or china, often characterized by their smooth, non-porous surfaces and precise manufacturing.

Distinguishing this subcategory from its sibling, 6909.11.40.00 ("Other"), is the material composition. While 6909.11.40.00 would encompass technical ceramic wares made from materials other than porcelain or china (such as stoneware, earthenware, or advanced technical ceramics), this particular classification is exclusively for those items manufactured from porcelain or china. The inherent properties of porcelain and china, such as high density, low porosity, and excellent electrical insulation, dictate their suitability for specific scientific and industrial applications.

As this classification represents a leaf node in the HTS database, there are no further subcategories. Therefore, classification under 6909.11.20.00 relies on a thorough examination of the article's intended use (laboratory, chemical, or technical), its physical characteristics, and confirmation that it is indeed manufactured from porcelain or china, aligning with the broader scope of ceramic wares for technical applications under heading 6909.
