## Common ground
All options are types of graduated kitchenware (measuring tools like cups, jugs, or containers with volume markings).
## Options at a glance
**3924.10 – Plastic material**
- **Defining trait:** Made from synthetic polymer resin, typically lightweight and impact-resistant.
- **Typical examples:** Plastic measuring cups, mixing bowls with volume scales.
- **Best fit when:** Durability, low cost, or portability is key; common in home kitchens.
**6911.10 – Porcelain or china**
- **Defining trait:** Fired clay with a vitrified, glossy surface; often decorative and heat-resistant.
- **Typical examples:** Elegant measuring jugs or serving bowls used in fine dining.
- **Best fit when:** Aesthetic appeal, high-end presentation, or oven-safe use is needed.
**6912.00 – Ceramic**
- **Defining trait:** Unglazed or glazed fired clay; more porous than porcelain but durable.
- **Typical examples:** Traditional kitchen measuring pots, rustic-style containers.
- **Best fit when:** Natural look, artisanal style, or moderate heat resistance is desired.
**7013.10,7013.4X – Glass**
- **Defining trait:** Transparent, non-reactive, and heat-resistant; allows visual monitoring of contents.
- **Typical examples:** Glass measuring cups, liquid jugs with clear volume markings.
- **Best fit when:** Clarity, hygiene, or precision in measurement is essential.
**7323.9X – Iron or steel**
- **Defining trait:** Metallic construction; strong and durable but prone to rust without coating.
- **Typical examples:** Heavy-duty measuring pots, industrial-style kitchen tools.
- **Best fit when:** Long-term durability, high heat exposure, or rugged use is required.
## Key differences
| Option | Material Type | Transparency | Heat Resistance | Common Use Case |
|-------|----------------|---------------|------------------|------------------|
| 3924.10 | Plastic | Opaque | Low to moderate | Everyday home use |
| 6911.10 | Porcelain | Opaque | High | Fine dining, decorative |
| 6912.00 | Ceramic | Opaque | Moderate | Artisanal, rustic kitchens |
| 7013.XX | Glass | Transparent | High | Precision, hygiene-focused |
| 7323.9X | Metal | Opaque | Very high | Industrial, heavy-duty |
## How to choose
- Is it transparent? → 7013.XX
- Is it made of fired clay with a glossy finish? → 6911.10
- Is it made of unglazed or matte-fired clay? → 6912.00
- Is it lightweight and flexible? → 3924.10
- Is it metallic and heavy-duty? → 7323.9X
## Overlaps & pitfalls
- Glass (7013.XX) and porcelain/ceramic may both be heat-resistant; prioritize transparency for glass.
- Porcelain and ceramic are both clay-based; use “glossy” vs. “matte/unglazed” to distinguish.
- Plastic and metal can both be durable, but plastic is lighter—use weight and material feel as clues.
- No clear priority: choose based on the product’s **main function** (e.g., precision → glass; durability → metal)
