## How to choose
- Is the mould made of metal? → 7323.9X or 7615.10
- Is it transparent and heat-resistant? → 7013.10,7013.4X
- Is it disposable or paper-based? → 4818.90
- Is it made of wood or natural material? → 4419
- Is it glossy, decorative, or fine tableware? → 6911.10
- Is it flexible, lightweight, and reusable? → 3924.10
## Overlaps & pitfalls
- Glass (7013) and porcelain/ceramic (6911/6912) may overlap in appearance; use "porcelain" for glossy, fine ware; "glass" if transparent.
- Plastic (3924.10) includes silicone—common in baking but not always obvious.
- Aluminium (7615.10) and steel (7323.9X) both metal; prioritize based on weight and conductivity.
- No priority rule given—choose by the product’s **main function or defining material**
