NICE Class 6 covers common metals and their alloys, ores, metal building and construction materials, transportable metal buildings, non-electric metal cables and wires, small metal hardware, metal storage containers and safes. It is a goods class organised by material — metal, not by function. In Nepal you register a Class 6 trademark with the Department of Industry, and protection covers only the class you file in.
Key Takeaways
- Class 6 is the common-metals class — raw metals and ores, metal building materials, hardware, pipes, containers and safes.
- It is classified by material: goods made of metal that aren't defined by another function belong here.
- It includes small hardware like bolts, screws and nails, and transportable metal buildings such as prefabricated houses.
- It excludes metal goods classified by function — tools (Class 8), furniture (Class 20), kitchen items (Class 21) — and electric cables (Class 9).
- Nepal's construction and steel sectors file heavily in Class 6.
- Register with the Department of Industry for a renewable 7-year term.
What does Trademark Class 6 cover?
Class 6 covers common metals and their alloys and ores; metal materials for building and construction; transportable buildings of metal; non-electric cables and wires of common metal; small items of metal hardware; metal containers for storage or transport; and safes. It is a material-based class: if a product is made of common metal and is not defined by a specific function that places it elsewhere, it usually sits in Class 6 — including metal statues and works of art of common metal.

What Class 6 does not include
The big trap in Class 6 is function versus material: a metal object with a defined function is classified by that function, not by being metal. Note these exclusions:
| Product | Correct class |
|---|---|
| Metals used for their chemical properties | Class 1 |
| Metals in foil/powder for painting, decorating, printing, art | Class 2 |
| Metal hand tools and implements | Class 8 |
| Electric cables | Class 9 |
| Metal pipes for sanitary installations | Class 11 |
| Metal furniture | Class 20 |
| Metal kitchen utensils and containers | Class 21 |
| Non-metal cables and ropes | Class 22 |
The rule of thumb: metal defined only as metal is Class 6, but a metal thing with a specific job — a tool, a cable, a pipe for plumbing, furniture, kitchenware — is classified by that job.
Who files in Class 6 in Nepal?
Class 6 is a cornerstone class for Nepal's construction and manufacturing economy. It is filed by steel and rebar producers, metal-pipe and tube makers, hardware and fastener manufacturers, prefabricated-structure and roofing suppliers, wire and cable (non-electric) makers, and safe manufacturers. With construction a leading sector nationwide, branded building-materials makers rely on Class 6 to protect their names. Confirm your class with the NICE Class Finder.
How to register a trademark in Class 6
Search the register for earlier metals and hardware marks, confirm Class 6 fits (and that a functional metal product doesn't belong in Class 8, 20 or 21), prepare your mark and specification, and file with the Department of Industry. It examines, publishes for the 90-day opposition window, and registers for a renewable 7-year term. See how to register a trademark in Nepal and how to search first.
Do you need more than one class?
Often. A hardware business might file in Class 6 for metal fasteners and in Class 8 for hand tools, or add construction-service classes. Because Nepal files one class per application with fees per class, map your range before filing. See choosing the right class, and the neighbouring Class 5 (Pharmaceuticals) and Class 7 (Machines).
Why precise Class 6 filing matters
Construction is one of Nepal's largest sectors, so Class 6 is busy and a precise filing pays off. A specification that names your real goods — "steel reinforcement bars", "metal roofing sheets", "metal fasteners" — protects what you actually make and avoids both under-protection and a needless conflict with unrelated metal-goods marks. Precision also keeps the material-versus-function line clean, so you know which of your products genuinely need Class 8, 20 or 21 instead. Because Nepal is first-to-file, the date you lodge the Class 6 application secures your priority in a competitive building-materials market. For a steel or hardware brand, an early, accurately scoped filing is what stops a competitor registering a similar name around your gaps.
Class 6 filing checklist
- Confirm your product is classified as metal, not by a specific function.
- Check the exclusions — Class 8, 9, 11, 20 or 21.
- Search the register for similar metals and hardware marks.
- Draft a precise goods specification.
- Consider Class 8 for tools or service classes for construction.
- File with the Department of Industry and track to registration.
A Nepal example
Consider a Nepali steel and hardware business. Its rebar, metal pipes, bolts and nails are Class 6, where its main trademark is filed. But the hand tools it also sells — hammers, spanners, manual cutters — are Class 8, and any metal furniture it manufactures is Class 20. Three product lines that all "come out of a metal workshop" fall into three different classes, because Class 6 is about metal as a material, while tools and furniture are classified by function. A brand that files only in Class 6 leaves its tools and furniture ranges unprotected.
Getting Class 6 right: common mistakes
The defining Class 6 mistake is ignoring the material-versus-function rule. Because Class 6 groups goods by being made of common metal, people wrongly assume every metal product belongs here. In reality a metal object with a specific job is classified by that job: metal hand tools are Class 8, metal furniture Class 20, metal kitchen utensils Class 21, and electric cables Class 9 — even though all are metal.
A second pitfall is pipes: metal pipes as building materials are Class 6, but metal pipes for sanitary or plumbing installations are Class 11. A third is filing metal foil or powder in Class 6 when it is meant for painting, decorating or art — that belongs in Class 2. Given how much of Nepal's construction supply chain touches Class 6, specify your actual goods and add Class 8 or other classes wherever your range includes functional metal products.
