## Overlaps & pitfalls
Some products may fit multiple categories if used across vehicle types (e.g., a pad used in both motorcycles and bicycles). However, the primary use determines the correct HS code. If unclear, prioritize based on the **main intended vehicle type**. Avoid confusion between "motor vehicles" and "trailers" — the latter are not self-propelled
