## Overlaps & pitfalls
- Glass (7013) and porcelain (6911.10) may both be non-porous and heat-resistant; choose based on appearance (transparent vs. opaque).
- Aluminum (7612) and steel (7323.9X) are both metals but differ in weight and conductivity.
- Tin (8007.00) is often used in lined or decorative forms—ensure it’s not just a coating.
- If multiple materials are present (e.g., plastic with metal base), prioritize the **main structural material**
