## Options at a glance
**7321.11 – Household use**
- **Defining trait:** Designed for residential, everyday cooking or heating in homes.
- **Typical examples:** Gas stoves, home ovens, kitchen ranges.
- **Best fit when:** The product is intended for domestic kitchens and used by individuals, not in commercial or industrial settings.
**8417 – Industrial/lab use**
- **Defining trait:** Built for large-scale manufacturing, processing, or scientific research environments.
- **Typical examples:** Industrial kilns, laboratory drying ovens, metal heat-treating furnaces.
- **Best fit when:** The product is used in factories, labs, or production facilities requiring high capacity, precision, or durability.
## Key differences
| Feature | 7321.11 (Household) | 8417 (Industrial/Lab) |
|---------------------|----------------------------|--------------------------------|
| Primary setting | Home kitchens | Factories, labs, workshops |
| Size & capacity | Smaller, limited capacity | Larger, high-capacity |
| Precision & control | Basic temperature settings | Advanced controls, automation |
## How to choose
- Is the product used in a home kitchen? → 7321.11
- Is it for manufacturing, research, or large-scale processing? → 8417
## Overlaps & pitfalls
A gas oven might serve both purposes if it's a high-end home model with lab-like precision—but its **main use** determines the classification. If unclear, prioritize based on **intended environment**: household vs. industrial/lab. Do not assume size alone defines the category; a small industrial oven still falls under 8417
