## Common ground
All options are draught excluders for doors, designed to seal gaps and prevent air leakage.
## Options at a glance
**3926.90 – Plastic material**
- **Defining trait:** Made from flexible or rigid plastic (e.g., PVC, polyethylene).
- **Typical examples:** Plastic door sweeps, foam-backed plastic strips, snap-in plastic seals.
- **Best fit when:** The excluder is lightweight, low-cost, and used in residential or temporary settings.
**4008.1X,4008.2X – Rubber sheets/strips (over 5 mm cross-section)**
- **Defining trait:** Made from thick vulcanised rubber (not hard rubber), with significant thickness and flexibility.
- **Typical examples:** Heavy-duty rubber door seals, floor-mounted rubber strips.
- **Best fit when:** High durability, weather resistance, or heavy use (e.g., industrial doors).
**4016.10,4016.9X – Vulcanised rubber (any cross-section)**
- **Defining trait:** Made from vulcanised rubber, including thinner profiles; may include foam-backed or composite designs.
- **Typical examples:** Rubber door seals with foam backing, flexible rubber gaskets.
- **Best fit when:** Need for flexibility, long-term sealing, or moderate to high weather resistance.
**6304.93 – Textile material**
- **Defining trait:** Made from fabric (e.g., felt, fleece, cotton), often with a soft, flexible texture.
- **Typical examples:** Felt door snakes, fabric draft stoppers, woven textile seals.
- **Best fit when:** Soft sealing, aesthetic appeal, or use in low-traffic areas.
## Key differences
| Option | Material Type | Thickness & Rigidity | Durability | Common Use Case |
|--------|---------------------|----------------------|------------|--------------------------|
| 3926.90 | Plastic | Low to medium | Medium | Residential, low cost |
| 4008.1X/2X | Thick rubber | High (>5 mm) | High | Heavy-duty, industrial |
| 4016.10/9X | Rubber (any size) | Variable | High | General-purpose sealing |
| 6304.93 | Textile | Low | Low | Decorative, temporary |
## How to choose
- Is it made of thick, flexible rubber over 5 mm? → 4008.1X,4008.2X
- Is it made of plastic (e.g., PVC, foam)? → 3926.90
- Is it made of rubber but thinner or composite (e.g., with foam)? → 4016.10,4016.9X
- Is it soft, fabric-based (e.g., felt, fleece)? → 6304.93
## Overlaps & pitfalls
- A rubber excluder with foam backing may fit both 4008.1X/2X and 4016.10/9X — priority depends on thickness: >5 mm → 4008; any size → 4016.
- Plastic foam strips might resemble textile ones (e.g., felt-like) — check material: if it’s plastic, use 3926.90.
- No clear hierarchy in the options; choose based on **primary material and physical structure**
