## Common ground
All options refer to women’s disposable undergarments designed for hygiene or incontinence, differing primarily in material composition and manufacturing method.
## Options at a glance
**4818.90 – Paper-based layers**
- **Defining trait:** The product is primarily made of paper (e.g., fluff pulp), which either imparts essential character or dominates by weight.
- **Typical examples:** Disposable sanitary pads with panty-like structure, paper-based incontinence briefs.
- **Best fit when:** The core material is paper, especially fluff pulp, and it’s the main structural or absorbent component.
**6108.2X – Knitted textiles**
- **Defining trait:** Made from knitted textile fabrics (e.g., cotton or synthetic fibers), even if disposable.
- **Typical examples:** Disposable cotton knit briefs, stretchable non-woven blends with knitted feel.
- **Best fit when:** The product has a knitted structure, offering elasticity and softness like traditional underwear.
**6208.9X – Woven textiles**
- **Defining trait:** Constructed from woven textile materials, not knitted or crocheted.
- **Typical examples:** Disposable cotton or polyester woven panties with minimal stretch.
- **Best fit when:** The fabric is tightly woven, lacks elasticity, and resembles traditional woven garments.
**6210.10 – Non-woven fabrics (56.02/56.03)**
- **Defining trait:** Made from non-woven fabrics like polypropylene, typically used for disposability and absorbency.
- **Typical examples:** Disposable incontinence briefs, soft non-woven sanitary wear.
- **Best fit when:** The material is a synthetic non-woven fabric (e.g., spunbond or meltblown), not knitted or woven.
**9619.00 – Adult incontinence underwear**
- **Defining trait:** Specifically designated for adult incontinence, regardless of material.
- **Typical examples:** High-absorbency briefs with leg cuffs and waistbands for adults.

## Key differences
| Option | Material Type | Structure | Primary Use |
|--------|---------------|-----------|-------------|
| 4818.90 | Paper (fluff pulp) | Layered | Absorbent hygiene |
| 6108.2X | Knitted textile | Elastic, stretchable | Disposable comfort wear |
| 6208.9X | Woven textile | Rigid, non-stretch | Basic disposable use |
| 6210.10 | Non-woven fabric | Lightweight, durable | High-performance disposables |
| 9619.00 | Any (but often non-woven) | Designed for incontinence | Adult incontinence care |
## How to choose
- Is the main material paper (e.g., fluff pulp)? → 4818.90
- Is it knitted (elastic, stretchy fabric)? → 6108.2X
- Is it woven (non-stretch, tight weave)? → 6208.9X
- Is it made from non-woven polypropylene or similar? → 6210.10
- Is it specifically for adult incontinence? → 9619.00
## Overlaps & pitfalls
A product may fit both 6210.10 and 9619.00 if made of non-woven fabric and intended for adult incontinence. Similarly, knitted or woven textiles may be used in incontinence products. The key is to prioritize the **main function**: if it’s for adult incontinence, use 9619.00; otherwise, classify by material and structure. Do not assume a product fits only one category—choose based on the dominant feature
