Last updated: August 2026 dataTankless (instantaneous) electric water heaters, traditional electric storage tank water heaters, and immersion heating elements serve both residential and light commercial applications and are classified together under this heading based on their electric resistance heating function. The distinction between instantaneous and storage types matters commercially — tankless units have seen strong demand growth tied to energy-efficiency building codes — but both fall within the same SITC heading. Energy efficiency standards administered by the Department of Energy apply to many water heater configurations sold in the US, and importers should confirm compliance before entry.

Yes. The US Department of Energy sets minimum energy efficiency standards for electric water heaters sold in the US market. Importers must ensure that products meet applicable Energy Factor or Uniform Energy Factor requirements before entry. Non-compliant units may be refused entry or require modification, and CBP coordinates with DOE on enforcement.
Standalone immersion heating elements designed for insertion into water tanks or vessels are classified within this same heading alongside complete water heater units. The key is that the element's function is electric resistance heating of water. Elements designed for industrial process heating of other liquids may be directed to a different heading depending on their design and application.
