Carpet and wallpaper have almost nothing in common as products, yet they share a trademark class — and the reason is a genuinely useful concept once you know it: Nice Class 27 covers coverings for an existing structure, things laid over a floor or wall that's already there, rather than materials that form part of the building itself. That single idea explains why carpets, rugs, mats, linoleum, artificial turf, and non-textile wall coverings all sit together.
Two Boundaries, Same Underlying Question
Class 27 sits between two neighbors, and both boundaries turn on the same question — is this laid over a finished surface, or is it structural? Textile fabric and bed linen are Class 24, distinct from carpet even though carpet is technically made of fibers too; the difference is that carpet is laid over an existing floor rather than being a soft-goods item like a sheet or towel. Ceramic and stone floor tiles are Class 19, because they form the floor itself as a building material rather than covering one that already exists. So a flooring brand selling both carpet and tile genuinely needs both Class 27 and Class 19 — the material sounds similar in casual conversation, but the classification logic treats them as fundamentally different categories.
| Product | Class | Why |
|---|---|---|
| Carpet, rugs, linoleum | 27 | Laid over an existing floor |
| Ceramic/stone tile | 19 | Forms the floor itself |
| Wallpaper | 27 | Laid over an existing wall |
| Textile wall hangings | 24 | Textile good, not a structural covering |
| Artificial turf | 27 | Artificial surface covering |
| Natural grass, live plants | 31 | Living agricultural product |
Filing for a Full Home Range
Mohawk and Shaw anchor the large-scale carpet and flooring side of Class 27, spanning both residential and commercial lines, while smaller rug and area-rug brands lean more on design-driven positioning. Home-furnishings companies with a broad range often need Class 27 alongside Class 24 (textiles) and Class 20 (furniture) — our Class 24 guide and Class 20 guide cover those neighboring classes. The most common misfile here is treating floor tile as though it belonged with carpet in Class 27, when the building-materials classification in Class 19 actually applies.
Wallpaper's Odd Place in a Flooring Class
It's worth dwelling on why wallpaper ended up in Class 27 rather than somewhere that sounds more intuitive, like the paper-goods class or a general home-decor category. The Nice Classification system was built around function rather than material or room, and wallpaper's function — a covering applied over an existing wall surface — is functionally identical to carpet's role on a floor. Both are decorative-but-non-structural layers added after construction is finished. That's also why non-textile wall hangings sit here while textile wall hangings sit in Class 24: the material matters less than whether the item is functioning as a surface covering or as a soft-goods textile object in its own right. A wallpaper brand that also sells fabric wall panels or tapestries genuinely needs to check both classes rather than assume "wall decor" is a single filing category.
A Filing Mistake Specific to Artificial Turf and Outdoor Surfaces
Artificial turf brands run into a classification wrinkle that carpet companies rarely face: the same company frequently sells both the turf itself (Class 27, an artificial surface covering) and installation or landscaping services to lay it (Class 37, Class 44 for landscaping specifically, depending on how the service is framed). A synthetic-turf manufacturer that also runs installation crews under the same brand name needs both the goods registration and a services registration — filing only the Class 27 goods mark leaves the installation-service side of the business, which is often where the actual customer relationship and repeat revenue live, without any registered protection at all. This mirrors the goods-versus-services split that shows up across the building and flooring classes generally, and it's worth checking before committing to a single-class filing strategy just because the product and the installation feel like one business.
Search registered Class 27 trademarks before you file, particularly across the Class 24 and Class 19 boundary if your product range spans more than one type of surface covering.
