## Overlaps & pitfalls
A microwave might be used in both settings (e.g., a large home oven used for catering), but the **main intended use** determines classification. The mention of "induction or dielectric loss" in 8514.20 is misleading—microwave ovens always work via dielectric loss; induction applies to cooktops, not microwaves. Do not confuse this with induction heating. Prioritize the **primary function and setting** over technical details
