Plain-language overview
Use HS-4 8403 when importing central heating boilers, such as gas or oil-fired units designed for residential or commercial heating. For example, a shipment of a gas-fired central heating boiler intended for a new building project falls under this heading.
When deciding between HS-6 840310 and HS-6 840390, consider whether you're importing a complete boiler or just parts. If your shipment includes a fully assembled central heating boiler, classify it under 840310. If it consists of components like heat exchangers or control systems, use 840390.
Both subheadings exclude boilers covered under HS-4 8402, which deals with steam or other vapor-generating boilers. Ensure your product does not fit that description to correctly apply HS-4 8403.
