8402 vs 8403 vs 8404: which heading fits your boiler

Three neighbouring headings deal with boilers. They are easy to mix up, so here is the short guide.

Its wording leaves out central heating hot water boilers, even those that can also make low pressure steam. Those belong in 8403.

Heading 8404 is not for the boiler itself. It covers the extra equipment that works with boilers of heading 8402 or 8403. It also covers condensers for steam or other vapour power units.

A simple test helps. Ask what the product does. If it heats a building and is not a steam or vapour boiler, look at 8403. If it makes steam or vapour, look at 8402. If it supports a boiler, look at 8404.

Duty and tax depend on your country, so check the national tariff once you have picked the code. If you are unsure which heading fits, the classifier can help you check.
