## How to choose
- Is the cover meant for long-term or repeated use? → 3926.90 or 6304.9X
- Is it used during shipping or temporary storage? → 4820.90
- Does it need to be soft and visually appealing? → 6304.9X
- Must it resist water or harsh conditions? → 3926.90
## Overlaps & pitfalls
A dust cover could be made of textile with plastic lining (e.g., waterproof fabric), fitting both 6304.9X and 3926.90. If unsure, prioritize the **main material** by weight or function. If the product is primarily fabric-based, use 6304.9X; if plastic dominates, use 3926.90. No option is inherently more correct—choose based on dominant material and intended use
