Last updated: April 2026 dataSuper-heated water boilers generate pressurized hot water above normal boiling point for district heating systems, industrial process heat, and large commercial facilities. Unlike steam boilers, these units operate in a liquid-phase pressurized loop, which affects both engineering specifications and classification at the border. Importers should confirm whether a unit qualifies as a super-heated water boiler versus a steam generator, as the distinction drives the applicable tariff line and any applicable Section 232 steel/aluminum content considerations for the pressure vessel components.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A super-heated water boiler maintains water in liquid phase under pressure at temperatures above 100°C, whereas a steam boiler produces vapor. Customs classification turns on the operating principle and design documentation; importers should provide technical specifications and engineering drawings to support the correct classification.
Yes. While US Customs and Border Protection handles tariff classification, super-heated water boilers intended for installation must typically comply with ASME Boiler and Pressure Vessel Code requirements enforced at the state level. Buyers should confirm code compliance before shipment to avoid costly retrofits or rejection by local inspectors.
