## Overlaps & pitfalls
A product could technically be both reusable and made of paper (e.g., a thick, coated paper liner), but such cases are rare and not standard. The key is **intended reusability**: if the product is marketed as washable and long-lasting, it’s 3924.10; if labeled “disposable” or “single-use,” it’s 4823.90. No clear priority rule exists—choose based on the product’s primary function
