## How to choose
- Is the pouch made of solid rubber? → 4016.99
- Is it primarily leather, fabric, plastic sheeting, or paperboard (even if covered)? → 4202.3X/4202.9X
- Is it made from actual animal bladder (not synthetic)? → 4206.00
- Is the main material solid wood, inlaid, or marquetry? → 4420.90
## Overlaps & pitfalls
- A leather pouch with a rubber lining may fit both 4202.3X and 4016.99; use the **main structural material**.
- "Bladder" (4206.00) is specific to animal-derived membranes—synthetic materials do not qualify.
- Wood (4420.90) applies only if wood is the primary material, not just a decorative element.
- If multiple materials are used, prioritize based on **main function and bulk**
