- Does it offer temperature control, cordless design, or digital interface? → 8516.79
## Overlaps & pitfalls
A kettle with automatic shut-off may still be basic electric (8516.10), so feature presence doesn’t always imply advanced status. The key is whether the product includes *user-adjustable* or *smart* functions. If multiple traits apply, prioritize based on the **main function**: if it’s primarily for precise temperature control, choose 8516.79; otherwise, use 8516.10 for standard electric models
