## Common ground
All options are insulated cabinets, meaning they provide thermal or electrical insulation, typically used for storing sensitive equipment or materials.
## Options at a glance
**9403.20 – Base metal**
- **Defining trait:** Constructed primarily from metals like steel or aluminum, offering high durability and heat resistance.
- **Typical examples:** Metal-framed insulated server cabinets, industrial refrigeration units.
- **Best fit when:** Requires robustness, fire resistance, or use in harsh environments.
**9403.40 – Wood**
- **Defining trait:** Made from solid wood or wood-based panels, offering natural insulation and aesthetic appeal.
- **Typical examples:** Wooden storage cabinets for labs, vintage-style insulated display units.
- **Best fit when:** Aesthetic integration, moderate insulation, or non-conductive use is key.
**9403.70 – Plastic material**
- **Defining trait:** Built from synthetic plastics (e.g., polyethylene, PVC), providing lightweight, corrosion-resistant, and good thermal insulation.
- **Typical examples:** Plastic-insulated toolboxes, portable medical storage units.
- **Best fit when:** Lightweight design, chemical resistance, or indoor use needed.
**9403.82 – Bamboo**
- **Defining trait:** Made from bamboo, a fast-growing natural material with moderate strength and insulation properties.
- **Typical examples:** Eco-friendly insulated storage for labs or green buildings.
- **Best fit when:** Sustainability focus, natural look, and moderate load capacity required.
**9403.83 – Rattan**
- **Defining trait:** Crafted from woven rattan, offering lightweight, flexible structure with moderate insulation.
- **Typical examples:** Decorative insulated cabinets in tropical or eco-design settings.
- **Best fit when:** Aesthetic design, light-duty use, and natural material preference.
**9403.89 – Other materials (cane, osier, etc.)**
- **Defining trait:** Made from non-metallic, non-plastic natural fibers like cane or willow; often handcrafted.
- **Typical examples:** Woven insulated storage for crafts or seasonal goods.
- **Best fit when:** Artisanal design, low weight, and use in decorative or temporary settings.
## Key differences
| Option | Material Type | Durability | Insulation Quality | Sustainability |
|--------|----------------|------------|--------------------|----------------|
| 9403.20 | Metal | High | Moderate | Low |
| 9403.40 | Wood | Medium | Good | Medium |
| 9403.70 | Plastic | Medium | High | Low |
| 9403.82 | Bamboo | Medium | Moderate | High |
| 9403.83 | Rattan | Low | Moderate | High |
| 9403.89 | Natural fiber | Low | Moderate | Very high |
## How to choose
- Is the cabinet made of metal (e.g., steel, aluminum)? → 9403.20
- Is it primarily wood or wood-based? → 9403.40
- Is it made from plastic (e.g., polyethylene, PVC)? → 9403.70
- Is the main material bamboo? → 9403.82
- Is it woven from rattan or similar flexible natural fiber? → 9403.83
- Does it use cane, osier, or other non-plastic, non-metallic natural materials? → 9403.89
## Overlaps & pitfalls
- Bamboo (9403.82) and rattan (9403.83) may be confused; bamboo is rigid, rattan is flexible and often woven.
- 9403.89 includes cane/osier but excludes bamboo/rattan—ensure material classification matches the actual fiber used.
- No clear priority rule: choose based on the **primary structural material**. If unsure, prioritize the most dominant or defining component
