Sub-classifications

Commodity Code
Description

Overview

This HTS category, 8419.90, encompasses "Parts" for machinery and equipment falling under heading 8419. This heading broadly covers various industrial and laboratory apparatus that utilize temperature changes for material treatment, such as heating, cooling, drying, and distilling. Therefore, 8419.90 specifically includes components, accessories, and subassemblies designed for use with these temperature-controlled processing machines, excluding complete finished articles covered elsewhere.

While sibling categories at the 8419 level describe specific types of apparatus like medical sterilizers (8419.20), distilling plant (8419.40), and heat exchange units (8419.50), this category is dedicated solely to the parts that constitute or support such equipment. For instance, it would cover heating elements, condensers, control panels, or structural components that are integral to the functioning of machinery classified under 8419, but are not the complete machine itself.

The subcategories within 8419.90 provide further refinement based on the type of parent machinery to which the parts belong. These subdivisions include parts for instantaneous or storage water heaters (8419.90.10.00), parts for machinery used in the production of paper pulp, paper, or paperboard (8419.90.20.00), and parts for heat exchange units (8419.90.30.00). An "Other" category exists for parts not falling into these specific classifications, ensuring comprehensive coverage for all related components.
