SITCSection 8
U.S. imports of central heating boilers (non-steam-power-generating) (SITC 81217) totaled $19.2M in April 2026, traded with 19 countries.
Importers of Central Heating Boilers (Non-Steam-Power-Generating) paid $4.2M in duties in April 2026 — an effective duty rate of 24% on $17.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Central Heating Boilers (Non-Steam-Power-Generating) imports of $19.2M in April 2026 ran 12% below the year-to-date monthly average of $21.8M.
Last updated: April 2026 dataHydronic central heating boilers — designed to heat water for space heating rather than to generate steam for power production — are a technically specific product category with distinct classification boundaries. The critical distinction from power-generating boilers is end-use: these units serve building heating systems and are not rated or designed for electricity generation or industrial steam supply. Iron and steel construction means Section 232 tariff applicability should be evaluated based on the specific HTS subheading and country of origin.

The distinction rests on design intent and output: central heating boilers produce hot water or low-pressure steam solely for space or water heating in buildings, while power-generating boilers produce high-pressure steam to drive turbines. Technical specifications such as operating pressure ratings and certifications (e.g., ASME codes) can support the classification determination.
Importers generally need commercial invoices with detailed technical specifications, country-of-origin certificates, and any applicable safety or efficiency certifications required by US state or local codes. If the boiler contains significant iron or steel content, mill certificates may also be needed to assess Section 232 tariff exposure.
