Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If steam production is 15-45 t per hour
Watertube boilers with lower steam output shift to the 8402.12 subheading based on capacity thresholds.
If designed for central heating with low-pressure steam capability
Boilers primarily for hot water central heating, even if producing some low-pressure steam, are classified in 8403.
If sold as a complete heat/steam power plant set
Assemblies combining boilers with engines or turbines for power generation may fall under complete plant provisions.
