## Common ground
All options are funnels made from different solid materials, used for transferring liquids or powders.
## Options at a glance
**3924.10,3926.90 – Plastic**
- **Defining trait:** Made from synthetic resin (plastic), lightweight and often disposable.
- **Typical examples:** Laboratory funnel, kitchen oil funnel, plastic funnel for fuel transfer.
- **Best fit when:** Low cost, flexibility, or single-use is needed; not for high heat or heavy-duty use.
**6911.10 – Porcelain or China**
- **Defining trait:** Made from vitrified ceramic, non-reactive and heat-resistant.
- **Typical examples:** Laboratory funnel in chemistry labs, precision labware.
- **Best fit when:** High chemical resistance, thermal stability, or laboratory use is required.
**6912.00 – Ceramic**
- **Defining trait:** Made from fired clay, less refined than porcelain; more porous and fragile.
- **Typical examples:** Traditional kitchen funnel, decorative funnel.
- **Best fit when:** Aesthetic or traditional use; not for precision or high-temperature applications.
**7323.9X – Iron or Steel**
- **Defining trait:** Made from ferrous metal, durable and heavy-duty.
- **Typical examples:** Industrial funnel for oil, fuel, or bulk material transfer.
- **Best fit when:** Long-term use, high durability, or handling corrosive or hot substances.
**7615.10 – Aluminium**
- **Defining trait:** Made from lightweight non-ferrous metal, corrosion-resistant and conductive.
- **Typical examples:** Portable funnel for camping, food processing, or chemical transfer.
- **Best fit when:** Lightweight, resistance to rust, and moderate durability are key.
## Key differences
| Option | Material Type | Durability | Heat Resistance | Weight | Common Use |
|-------|----------------|------------|------------------|--------|-------------|
| 3924.10,3926.90 | Plastic | Low | Low | Light | Disposable, low-cost |
| 6911.10 | Porcelain/China | Medium | High | Medium | Lab precision |
| 6912.00 | Ceramic | Low | Medium | Medium | Decorative/traditional |
| 7323.9X | Iron/Steel | High | High | Heavy | Industrial |
| 7615.10 | Aluminium | Medium | Medium | Light | Portable, corrosion-resistant |
## How to choose
- Is it used in a lab or for precise chemical transfer? → 6911.10
- Is it lightweight and likely disposable? → 3924.10,3926.90
- Is it made of metal and used for heavy-duty tasks? → 7323.9X
- Is it made of non-ferrous metal and needs to resist rust? → 7615.10
- Is it decorative or traditional in style? → 6912.00
## Overlaps & pitfalls
- Porcelain (6911.10) and ceramic (6912.00) can overlap; porcelain is a type of ceramic, but the HS code distinguishes them by refinement. Use 6911.10 for lab-grade, 6912.00 for general ceramic.
- Plastic funnels may be mistaken for metal if reinforced, but material is clear from composition.
- No option is vague; all are distinct by material type and typical use.
- If unsure, prioritize the **main function**: lab → porcelain; industrial → steel; portable → aluminium; low-cost → plastic; traditional → ceramic
