Last updated: August 2026 dataGas-fired, propane, and other nonelectric water heaters — both tankless (instantaneous) and storage-tank designs — fall here when not classified elsewhere in the schedule. The US tariff schedule distinguishes instantaneous nonelectric units (8419190120) from other nonelectric instantaneous or storage heaters (8419190160), a split that matters for duty calculation and trade-remedy exposure. These products serve residential, commercial, and industrial end-uses, and units of Chinese origin may carry Section 301 tariff liability depending on the specific line.

An instantaneous (tankless) heater heats water on demand as it flows through the unit, with no storage reservoir. A storage heater maintains a heated water volume in a tank. The distinction is structural and functional; CBP may request technical specifications or product literature to confirm the correct subheading between 8419190120 and 8419190160.
Yes. 'Not elsewhere specified or included' means this heading is a residual catch-all for nonelectric water heaters not captured by solar (841912) or other specific headings. Combination units — for example, a boiler that also provides domestic hot water — may be more properly classified under a boiler heading. A binding ruling from CBP is advisable for multi-function appliances.
