## Common ground
All options are types of conveyor belts classified by their primary material.
## Options at a glance
**3926.90 – Plastic**
- **Defining trait:** Made primarily from synthetic plastic materials like PVC or polyethylene.
- **Typical examples:** Lightweight, food-grade belts for packaging lines; chemical-resistant belts.
- **Best fit when:** Used in clean environments (e.g., food, pharmaceuticals) or where corrosion resistance is key.
**4010.3X – Rubber**
- **Defining trait:** Constructed from natural or synthetic rubber, often with fabric reinforcement.
- **Typical examples:** Heavy-duty belts for mining, bulk material handling, or outdoor use.
- **Best fit when:** High durability, shock absorption, and grip are needed in rugged conditions.
**4205.00 – Leather/Composition leather**
- **Defining trait:** Made from animal hide or synthetic leather-like materials; less common today.
- **Typical examples:** Vintage industrial belts; specialized applications requiring high friction.
- **Best fit when:** Historical, decorative, or niche use (e.g., artisanal equipment); not typical for modern bulk transport.
**5910.00 – Textile**
- **Defining trait:** Fabric-based, often with a woven textile core and coated surface (e.g., polyester or nylon).
- **Typical examples:** Light to medium-duty belts in packaging, printing, or assembly lines.
- **Best fit when:** Flexibility, moderate load capacity, and cost-effectiveness are priorities.
**7326.90 – Iron/Steel**
- **Defining trait:** Made from metal (steel or iron), typically used in high-load or extreme-temperature environments.
- **Typical examples:** Chain-driven belts in steel mills; continuous casting systems.
- **Best fit when:** High strength, heat resistance, and long-term durability under heavy loads are required.
## Key differences
| Feature | Plastic | Rubber | Leather | Textile | Iron/Steel |
|------------------|-------------|-------------|---------------|-------------|---------------|
| Material | Synthetic plastic | Natural/synthetic rubber | Animal/hide or synthetic leather | Woven fabric | Metal (steel/iron) |
| Load capacity | Low–medium | High | Medium | Medium | Very high |
| Environment | Clean, dry | Rugged, wet | Niche | General | Extreme heat |
| Common use | Food, light industry | Mining, bulk handling | Artisanal, vintage | Packaging, printing | Heavy industry |
## How to choose
- Is the belt used in food or clean environments? → 3926.90
- Does it handle heavy, abrasive materials outdoors? → 4010.3X
- Is it for a historical or decorative setup? → 4205.00
- Is flexibility and moderate strength needed? → 5910.00
- Is it in high heat or under extreme load? → 7326.90
## Overlaps & pitfalls
A belt may combine materials (e.g., textile core with rubber coating), but the **primary material** determines classification. If unclear, prioritize the dominant structural component. No option is vague, but "composition leather" (4205.00) may be misinterpreted—clarify if synthetic or animal-based
