## Overlaps & pitfalls
A holder can be both magnetic *and* made of metal (e.g., a steel magnetic mount). In such cases, **magnetic function takes priority** if the primary purpose is magnetic attachment. If not specified, choose based on the **main functional feature**: magnetism vs. material. Avoid confusion between material and mechanism—e.g., a plastic holder can be magnetic, but its HS Code depends on the dominant trait
