8416.20.00.40 - Gas burners

This HTS category, 8416.20.00.40, specifically covers gas burners designed for use in furnaces. These burners are characterized by their function of combusting gaseous fuels to generate heat for industrial or commercial furnaces. The scope includes burners that utilize natural gas, propane, butane, or other combustible gases as their fuel source, intended for applications such as heating, smelting, or drying processes.

Within the broader heading of furnace burners, this subcategory is distinguished from other potential classifications by its exclusive focus on gas as the fuel medium. While heading 8416.20.00 encompasses a range of furnace burners, including those for liquid or pulverized solid fuels, this particular code zeroes in on gas combustion technology. It is important to note that mechanical stokers, grates, and ash dischargers, though related to furnace operation, are classified separately.

As this is a leaf node in the HTS structure, there are no further subdivisions for this specific classification. Therefore, classification within 8416.20.00.40 relies on confirming the product is indeed a furnace burner and that its primary fuel source is gas. Items that do not meet these criteria, such as burners for other fuel types or components that are not integral to the combustion process, would fall under the sibling category, 8416.20.00.80, for "Other" furnace burners.
