## Common ground
All options are types of photographic cameras, used to capture still images.
## Options at a glance
**9006.30 – Underwater, aerial, or medical use**
- **Defining trait:** Designed for specialized environments or purposes like underwater diving, aerial surveys, or internal organ examination.
- **Typical examples:** Underwater housing cameras, drone-mounted cameras, endoscopic cameras.
- **Best fit when:** The camera is built for extreme conditions, non-traditional angles, or medical diagnostics.
**9006.40 – Instant print cameras**
- **Defining trait:** Produces physical prints immediately after taking a photo, using built-in film or printing technology.
- **Typical examples:** Polaroid cameras, Fujifilm Instax cameras.
- **Best fit when:** The user wants immediate, tangible photos without digital processing.
**9006.5X – Other photographic cameras**
- **Defining trait:** General-purpose cameras not falling into the above specialized categories.
- **Typical examples:** DSLR cameras, mirrorless cameras, compact point-and-shoots.
- **Best fit when:** The camera is used for everyday photography and lacks special features like instant printing or medical/industrial design.
## Key differences
| Feature | 9006.30 | 9006.40 | 9006.5X |
|-----------------------|--------------------------|------------------------|-------------------------|
| Primary use | Specialized environments | Instant physical output| General photography |
| Output method | Digital or film (no print)| Built-in printing | Digital or film (no print) |
| Design focus | Rugged, sealed, or medical| Integrated printer | Versatile, standard |
## How to choose
- Is the camera designed for underwater, aerial, or medical use? → 9006.30
- Does it produce a physical photo immediately after taking a picture? → 9006.40
- Is it a standard camera without special features? → 9006.5X
## Overlaps & pitfalls
A camera could combine traits (e.g., an underwater camera with instant print). In such cases, prioritize the **main function**: if it’s for medical or extreme environments, use 9006.30; if printing is central, use 9006.40. If neither applies, choose 9006.5X. The label “other” is a fallback—avoid it if a more specific category fits
