- **Defining trait:** Constructed from synthetic plastic, typically non-biodegradable and often more rigid than textile versions.
- **Typical examples:** Plastic-coated nylon laces, PVC laces, or molded polyester cords.
- **Best fit when:** The lacing is stiff, shiny, or designed for durability in wet or high-friction environments.
**5609.00,6307.90 – Made of textile material**
- ****Defining trait:** Crafted from woven or knitted fabric fibers (e.g., cotton, polyester, silk), offering flexibility and a softer feel.

- **Best fit when:** The lacing is soft, flexible, or intended for aesthetic appeal and comfort.

## Overlaps & pitfalls
A product may combine plastic coating with textile core (e.g., a cotton lace with a plastic sheath), which could fit both codes. In such cases, the **primary material** determines classification: if the bulk is plastic, use 3926.90; if textile, use 5609.00,6307.90. No priority rule is implied—choose based on the dominant material
