Last updated: April 2026 dataLiquid-fuel burners designed for industrial and commercial furnaces — including oil-fired units used in steel reheat furnaces, ceramic kilns, and process heaters — are classified under SITC 74121. These components are key efficiency drivers in energy-intensive industries, where burner design directly affects fuel consumption, emissions compliance, and throughput. Importers should be aware that burner assemblies may be subject to Section 301 additional duties depending on origin, and that EPA combustion-equipment regulations can affect admissibility for certain end-use applications. Distinguishing a complete burner assembly from its individual components (nozzles, atomizers, control valves) is important for accurate classification.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A complete burner assembly — comprising a fuel pump, atomizer, ignition system, and air register presented together — is classified as a complete burner under SITC 74121. Individual components such as nozzles or atomizer tips imported separately are generally classified as parts. Presenting components together in a single shipment does not automatically make them a complete assembly; functional completeness is the test.
EPA combustion and emissions standards govern how liquid-fuel burners may be used in the US, particularly for industrial boilers and process heaters subject to National Emission Standards for Hazardous Air Pollutants (NESHAP). While EPA does not typically block importation at the border, importers supplying burners for regulated facilities should confirm that the equipment meets applicable performance standards before sale, as non-compliant units may not be legally installed.
