Last updated: April 2026 dataHot-water and steam radiators fabricated from iron or steel are a staple of hydronic heating systems in residential and commercial construction, particularly in European-style building designs. Iron and steel content makes these articles potentially subject to Section 232 tariffs, and importers should confirm country of origin and steel mill certifications to assess exposure. Parts classified under this heading — such as sections, headers, and end caps — may carry different duty treatment than complete radiator assemblies.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Complete radiators are classified as finished goods, while individual sections, manifolds, and fittings that are identifiable as radiator parts fall under the parts provision. The key classification test is whether the item can function independently as a radiator or serves solely as a component of one.
Iron and steel radiators may be subject to Section 232 tariffs depending on their classification and country of origin. Importers should review current Section 232 product exclusion lists and confirm the applicable HTS subheading with a licensed customs broker to determine actual duty exposure.
