HS Code for Central heating boilers

Central heating boilers are classified under HS code 8403.10. This classification is governed by the specific exclusion found in heading 8402, which covers steam-generating boilers. Heading 8403 is dedicated to boilers used for central heating that are not designed to produce high-pressure steam for power or industrial use. These boilers typically circulate hot water or low-pressure steam through a closed-circuit system to radiators or underfloor heating pipes. The classification 8403.10 applies regardless of the fuel source, meaning gas-fired, oil-fired, and electric central heating boilers all fall under this category. The technical distinction relies on the boiler's primary purpose: providing space heating for residential, commercial, or institutional buildings. Under Section XVI, Note 2, parts for these boilers are classified separately under 8403.90, but the complete boiler unit, even if presented unassembled for ease of transport, remains under 8403.10.

Products Included

• Gas-fired domestic central heating boilers
• Oil-burning boilers for residential heating
• Electric central heating boilers
• Combination (combi) boilers for space heating and hot water
• Cast iron sectional boilers for commercial heating

Common Misclassification

A frequent point of confusion occurs between HS code 8403.10 and HS code 8402.19. Heading 8402 is for steam or other vapor generating boilers used in industrial processes or power generation. If a boiler is capable of producing high-pressure steam, it must be classified under 8402, even if it is used for heating. Another common error is classifying electric boilers under 8516.10 (electric instantaneous or storage water heaters). However, if the device is designed for a central heating system rather than just domestic hot water, 8403.10 takes precedence.

FAQ

What is the HS code for Central heating boilers?
