Overview of Class 6
Trademark Class 6 is the primary international classification for common metals and their alloys, metal building materials, transportable buildings of metal, materials of metal for railway tracks, non-electric cables and wires of common metal, ironmongery, small items of metal hardware, pipes and tubes of metal, safes, and ores.
Registering in Class 6 is a fundamental step for businesses in the heavy industry, infrastructure, and hardware sectors. This class protects brand identifiers for raw metals like iron and steel, as well as finished goods like nuts, bolts, metal pipes, and high-security safes. In India’s rapidly industrializing economy, a Class 6 trademark provides the legal authority to prevent "knock-off" industrial components from being sold under your brand name, ensuring structural integrity and brand reliability across the supply chain.
What is included?
- •Raw Metals: Iron, steel, aluminum, copper, and their alloys in raw/semi-wrought form
- •Building Materials: Metal beams, roofing sheets, fencing, and scaffolding
- •Small Hardware: Nuts, bolts, screws, nails, hinges, and locks
- •Pipes & Tubes: Metal pipes for plumbing, drainage, and industrial use
- •Security Storage: Metal safes, strongboxes, and cashboxes
- •Infrastructure: Metal rails and components for railway tracks
- •Cables & Ropes: Non-electric metal cables, wire ropes, and chains
- •3D Printing: Metals in foil or powder form for 3D printers
What is excluded?
- •Precious metals and their alloys, jewelry (Class 14)
- •Metal hand tools and implements (Class 8)
- •Metal household utensils and vessels (Class 21)
- •Metal furniture (Class 20)
- •Electric cables and wires (Class 9)
- •Surgical and medical instruments of metal (Class 10)
- •Construction services using metal (Class 37)
The Backbone of Industrial Branding
Class 6 is the legal home for the hardware and construction materials industries. For giants like Tata Steel, JSW Steel, and Jindal Stainless, a Class 6 registration is what ensures that "Steel" isn’t just a commodity, but a branded promise of quality.
Proper classification is vital to avoid trademark refusal. For example, while a metal bolt is Class 6, the wrench used to tighten it is Class 8. Similarly, while a metal safe is Class 6, the high-security electronic lock inside it might require Class 9 protection.
India’s infrastructure boom makes Class 6 one of the most litigated and defended classes. Protecting your brand here prevents competitors from using similar names on industrial components that could compromise project safety if they are of inferior quality.

Common Misconceptions & Registration Steps
- Material vs. Function: Just because a product is made of metal does not automatically mean it belongs in Class 6. A gold ring is Class 14, and a metal spoon is Class 21.
- Surgical Tools: Medical scalpels and forceps, though stainless steel, belong in Class 10.
- Hand Tools: Hammers and wrenches are categorized by use in Class 8, not by material in Class 6.
- Search Strategy: Always perform a thorough search in Class 6 and related classes like Class 19 (Construction) to avoid legal conflicts.
- Emerging Tech: Metals in powder form for 3D printing were recently added to Class 6, making it vital for advanced manufacturing startups.
Strategic Asset Creation
A Class 6 trademark is more than just a name; it is an intangible asset that can be licensed, franchised, or even appear on a company’s balance sheet. In heavy industry, brand goodwill can represent a significant portion of a company’s market value.
Section 9 Objections: Avoid generic names like "IRON PIPES" or "STRONG STEEL". These lack distinctiveness and will be rejected by the Registrar.
Section 11 Objections: If your brand name resembles a major player (e.g., "TATA LUBRICANTS" vs "TATA STEEL"), you will face relative grounds for refusal even if your specific products differ slightly.
