About HS Code 840310
This HS code covers central heating boilers, excluding those that generate steam or vapor (which fall under 8402). These boilers are primarily designed to produce hot water for heating systems in residential, commercial, and institutional buildings, supplying radiators, underfloor heating, or domestic hot water. Their trade is a significant part of the global HVAC market, driven by new construction, renovation projects, energy efficiency standards, and shifts in fuel preferences (e.g., natural gas, oil, biomass, electric). Importers are typically construction companies, HVAC distributors, wholesalers, and retailers. Exporters are manufacturers specializing in heating technology, often offering a range of models to suit different building sizes, energy requirements, and regulatory environments. The market is highly competitive, with a strong focus on efficiency and environmental performance.
Products Under This Code
Gas-fired central heating boilers, oil-fired central heating boilers, biomass central heating boilers, condensing boilers, combi boilers, system boilers, regular boilers, electric central heating boilers
Real World Examples
Vaillant gas boilers, Worcester Bosch condensing boilers, Baxi combi boilers, Viessmann central heating boilers
Common Misclassification
Crucially distinguished from steam or vapor generating boilers (8402) as these primarily produce hot water for heating, not steam. Also, they are different from water heaters (841919) which are typically smaller and for domestic hot water only.
Products Classified Under 8403.10
Industry
This code belongs to the Electronics & Electrical Equipment industry.
Trade Overview
Germany, Italy, the UK, and China are major exporters, supplying a global market focused on residential and commercial building heating solutions.
