8419.90.50.40 - Of medical, surgical or laboratory sterilizers

This HTS category, 8419.90.50.40, specifically covers parts and accessories designed for medical, surgical, or laboratory sterilizers. These sterilizers are machines that utilize processes involving a change in temperature to eliminate microorganisms and render items sterile. Examples of goods falling under this classification include replacement components for autoclaves, steam sterilizers, dry heat sterilizers, and other similar equipment used in healthcare settings or scientific research laboratories.

This category is distinguished from its sibling, 8419.90.50.80 ("Other"), by its specific application. While the "Other" category would encompass parts for any machinery covered by heading 8419 that do not fit into the more specific categories provided, 8419.90.50.40 is exclusively for parts of sterilizing equipment used in medical, surgical, or laboratory contexts. It is crucial to identify the intended use and design of the part to ensure correct classification.

As this is a leaf node within the HTS, there are no further subcategories. Classification within this code depends on the part's direct relationship to the functioning of a medical, surgical, or laboratory sterilizer, rather than other types of temperature-altering machinery.
