## Overlaps & pitfalls
A basket could be made of metal but plated (e.g., zinc-plated steel), making both 7324.90 and 7907.00 possible. Similarly, glass and ceramic may look similar if unglazed. **No option is inherently more important**—choose based on the **primary material** used in construction. If unsure, prioritize the dominant or structural material
