Class 6 under the Nice Classification for Trademarks covers common metals and their alloys, as well as metal building materials, transportable metal structures, and metal hardware, excluding machinery or finished goods classified elsewhere.
Businesses engaged in metal manufacturing, construction materials, infrastructure, hardware, and industrial metal products typically fall within Trademark Class 6.
Scope
Class 6 includes goods made primarily of common metals used for construction, infrastructure, industrial, or structural purposes.
Goods covered under this class generally include:
- Common metals and their alloys
- Metal building and construction materials
- Transportable metal structures
- Metal pipes, tubes, and frameworks
- Metal hardware, fittings, and fasteners
- Metal safes and storage structures
- Metal doors, windows, and shutters
- Non-electric metal cables and wires
Classification principle: If the product is predominantly made of common metal and is not a machine, electrical device, or finished consumer product, it generally falls within Class 6.
Key Updates – Nice Classification (2026 Update)
As per the Nice Classification updates 2026, the following clarifications are particularly relevant to Class 6:
Clearer separation between:
- Metal materials and structures (Class 6), and
- Machinery, tools, or mechanical components (Class 7)
Refined terminology to reduce overlap with:
- Electrical cables and components (Class 9)
- Building materials made primarily of non-metal substances (Class 19)
Metal structures for EV charging stations and green construction materials have been clarified under Class 6. Earlier, such items were often filed generically. With the expansion of EV infrastructure and sustainable construction, businesses must now file more precise specifications in this class.
Practical takeaway: Multi-material products must be classified based on their dominant material to avoid objections.
Goods NOT Included in Class 6 (But Commonly Confused)
The following goods are excluded from Class 6, despite frequent misclassification:
- Machines, motors, and mechanical tools (Class 7)
- Electrical wires, cables, and conductors (Class 9)
- Building materials made of non-metal (Class 19)
- Hand tools and implements (Class 8)
- Metal furniture and household goods (Class 20)
- Vehicles and vehicle parts (Class 12)
Why Correct Nice Class 6 Classification Is Important
Incorrect trademark classification under Nice Class 6 can lead to:
- Trademark examination objections
- Limited or incorrect scope of protection
- Increased vulnerability in enforcement and infringement disputes
A properly drafted Nice Class 6 trademark specification ensures effective protection across metal goods, construction materials, and infrastructure products.
