## Overlaps & pitfalls
- A textile blind with aluminum slats may fit both 6303 and 7616.99; prioritize the **main structural material**.
- Plastic blinds can resemble wood or aluminum in appearance—do not rely on look alone.
- Woven glass fabrics are rare; ensure it’s not confused with regular fabric (6303).
- If unsure, identify the **primary functional material** (e.g., slats vs. fabric vs. sheet)
