## Common ground
All options are types of decorative laminates used for surface finishing in furniture, cabinetry, and interior design.
## Options at a glance
**3921.90 – Plastic-based**
- **Defining trait:** Made primarily from thermosetting plastics like melamine or phenolic resins.
- **Typical examples:** Melamine-faced panels, durable kitchen countertops, office furniture surfaces.
- **Best fit when:** The laminate has a hard, scratch-resistant surface with high durability and moisture resistance.
**4823.90 – Paper-based**
- **Defining trait:** Made from paper or paperboard impregnated with resins, often used for decorative printing.
- **Typical examples:** Printed wood-grain panels, low-cost wall cladding, temporary interior finishes.
- **Best fit when:** The product relies on printed designs and is less durable, commonly used in budget or short-term applications.
## Key differences
| Feature | 3921.90 (Plastic-based) | 4823.90 (Paper-based) |
|--------------------|--------------------------|------------------------|
| Base material | Plastic resins | Paper/paperboard |
| Durability | High | Moderate to low |
| Surface finish | Hard, glossy, scratch-resistant | Soft, printed, less durable |
| Common use | Permanent fixtures | Temporary or budget use |
## How to choose
- Is the surface hard and resistant to scratches/water? → 3921.90
- Is it primarily a printed paper layer with no plastic coating? → 4823.90
## Overlaps & pitfalls
Some laminates blend both materials (e.g., paper core with plastic top layer), which may fit both codes. In such cases, the **main functional layer** determines classification: if the surface is plastic-based and durable, use 3921.90; if it’s paper-based with a printed design, use 4823.90. The defining trait should be based on the **primary material and intended performance**, not just appearance
