## Overlaps & pitfalls
- Plastic trays may be reinforced with fiberglass (still 3922.10).
- Ceramic trays can be made with metal frames (still 6910).
- Stainless steel and aluminium trays may look similar; check material specs.
- Copper and zinc trays are often decorative—prioritize the **main function**: structural vs. aesthetic. If unclear, use the **primary material** as the deciding factor
