8416.20.00 - Other furnace burners, including combination burners

This category, HTS Code 8416.20.00, encompasses furnace burners that are not specifically designed for liquid fuel, pulverized solid fuel, or gas, and are not mechanical stokers. It serves as a residual category for furnace burners not falling under the more specific subheadings within heading 8416. The primary function of these burners is to introduce and combust fuel within a furnace or boiler to generate heat.

Distinguishing this category from its siblings, 8416.10.00.00 covers burners explicitly for liquid or pulverized solid fuels, while 8416.30.00.00 pertains to mechanical stokers and related ash-handling equipment. Therefore, 8416.20.00 is for burners of other types or combinations not precisely defined in the other primary burner categories.

The subcategories of 8416.20.00 further refine this classification. Subheading 8416.20.00.40 specifically covers gas burners, which are a distinct type of burner. The residual subheading, 8416.20.00.80, is for "Other" furnace burners that do not fit into the gas burner subcategory, covering a range of burner designs not otherwise specified.
