What Is Nice Class 17?
Nice Class 17 is the trademark classification for semi-finished rubber, plastics, and insulating materials. It covers rubber and plastics in semi-worked form (sheets, rods, tubes), insulating materials of all kinds, seals, gaskets and packing materials, flexible non-metal pipes and hoses, weatherstripping, and soundproofing and waterproofing materials. It is a specialized industrial-materials class sitting between the raw chemistry of Class 1 and the finished goods made from these materials.
The defining concept is semi-finished material. Class 17 covers rubber and plastic that has been processed into a usable intermediate form — but not the raw polymer (Class 1) and not the finished consumer product. A sheet of insulating foam or a length of rubber hose is Class 17; the unprocessed resin is Class 1, and a finished plastic container is in its product class.
What Class 17 Covers
- Semi-worked rubber, gutta-percha, and plastics (sheets, rods, tubes)
- Insulating materials: thermal, acoustic, and electrical insulation
- Seals, gaskets, O-rings, and packing materials
- Flexible non-metal pipes and hoses
- Weatherstripping and draft-proofing materials
- Soundproofing and waterproofing materials
- Adhesive tapes for industrial use (in applicable cases)
- Plastic films for industry (non-packaging)
Exclusions: raw unprocessed plastics and resins are Class 1; rigid metal pipes are Class 6; non-metal building materials like rigid plastic building components can be Class 19; and finished plastic consumer goods are in their relevant product class. The same polymer can pass through Class 1 (raw), Class 17 (semi-finished), and a goods class (finished) along its lifecycle.
Boundary note: A flexible non-metal hose is Class 17, but a rigid metal pipe is Class 6 and a non-metal rigid building pipe can be Class 19. The combination of material and form decides the class, which is why materials companies often file across several.
The Material Lifecycle Across Classes
Class 17 sits in the middle of a chain. Raw rubber and plastic resins are Class 1 inputs; semi-finished sheets, tubes, seals, and insulation are Class 17; and finished products are classified by what they become. A materials manufacturer with a broad catalog frequently files across Class 1, Class 17, and Class 19, because its range spans raw chemistry, semi-finished materials, and building products. Our Class 1 guide covers the raw-input end and our Class 19 guide the building-materials end of this relationship.
Filing Strategy in Industrial Materials
Like other industrial classes, Class 17 is overwhelmingly B2B, with goods sold to manufacturers and builders. Brand names tend to be coined or arbitrary, so descriptiveness refusals are uncommon. The main clearance considerations are the density of similar technical names and the need to choose the correct class among the several a materials catalog can touch. Distinctive names register most easily and best support enforcement in markets where products are sold on specification.
Notable Brands in Class 17
- 3M — industrial tapes, seals, and insulating materials across a deep portfolio
- DuPont — engineered materials and insulation products
- Industrial sealing and gasket brands — anchoring the packing-and-sealing side of the class
- Insulation manufacturers — thermal and acoustic insulation marks
Common Filing Mistakes
- Filing raw resins in Class 17: unprocessed plastics are Class 1.
- Filing metal pipes in Class 17: rigid metal pipes are Class 6.
- Filing finished plastic goods in Class 17: finished products go in their product class.
- Single-class filing for a broad catalog: materials makers often need several classes.
Frequently Asked Questions
What's the difference between Class 1 and Class 17 for plastics?
Class 1 covers raw, unprocessed plastics and resins as chemical inputs. Class 17 covers semi-finished plastics — sheets, rods, tubes, films, and similar intermediate forms ready for further manufacturing. Finished plastic products go in their relevant goods class. The same polymer passes through all three stages.
Are pipes and hoses in Class 17?
Flexible non-metal pipes and hoses are in Class 17. Rigid metal pipes are Class 6, and rigid non-metal building pipes can be Class 19. The classification depends on both material and form, so a piping manufacturer may file across several classes depending on its range.
Is insulation in Class 17?
Yes. Insulating materials — thermal, acoustic, electrical, and weatherproofing — are in Class 17, along with seals, gaskets, and packing materials. The class covers these as semi-finished industrial materials rather than as finished building components.
Do industrial materials names face descriptiveness refusals?
Less often than consumer-goods names, because brands in this space typically use coined or arbitrary names. The bigger clearance challenge is the density of similar technical names across overlapping material categories and selecting the correct class among Class 1, Class 17, and Class 19.
Search Class 17 Before You File
Rubber, plastics, and insulation names overlap across the material lifecycle and adjacent classes, so clearance is worthwhile even in B2B markets. Use tmarkmetric to browse registered Class 17 trademarks, see which names are taken, and search the broader registry before you commit. File across the right classes for a broad materials catalog.
