Trademark Class 6 —
Common Metals, Hardware
& Building Materials India
Complete guide to TM Class 6: official goods list, Class 6 vs Class 7, registration fees, top Indian steel & hardware brands & expert FAQs — updated for 2026.
What is Trademark Class 6 in India?
TM Class 6 (Trademark Class 6) covers common metals and their alloys; metal ores; metal building and construction materials; transportable buildings of metal; non-electric cables and wires of metal; metallic pipes and tubes; safes and lockboxes; metal hardware and ironmongery; and metal containers for storage or transport — under the NICE Classification 13th Edition used by IP India.
If your business manufactures, sells, imports or exports steel, iron, aluminium, copper, zinc products; metal pipes, tubes and fittings; locks, safes and keys; metal hardware; wire and cables (non-electric); metal building materials; prefabricated metal structures; or metal containers, you need a TM Class 6 trademark to protect your brand across India for 10 years.
India’s steel and metals sector is valued at over ₹10 lakh Crore, with leading brands like Tata Steel, JSW Steel, SAIL, Godrej Locks, Astral Pipes, Finolex, Polycab and Jindal Steel all registered under TM Class 6 with IP India.
Simple AI Explanation — Class 6 in Plain Language
If your product is made of metal and you sell it as a physical product — it is almost certainly Class 6. The exception: metal tools with cutting edges (Class 8), electrical metal products (Class 9), and metal machinery (Class 7).
✔ Iron gate = Class 6
✔ Steel TMT bar = Class 6
✔ Metal pipe = Class 6
✔ Padlock and safe = Class 6
✔ Steel building/shed = Class 6
✔ PVC pipe = Class 17 (not Class 6)
Many hardware brands file only in Class 7 (machinery) and miss Class 6 (metal products). If you sell both metal goods and machines, you need both Class 6 and Class 7. Filing in only one = incomplete brand protection.

How to Register a Trademark Under Class 6 in India
Step-by-step guide to registering your metal, hardware or building material brand under TM Class 6 with IP India in 2026.
Trademark Search — Start Here
Search IP India’s portal at tmrsearch.ipindia.gov.in for identical or similar marks in Class 6. The steel and hardware sector has strong regional brands — a brand popular in Gujarat may already be registered nationally. Check your brand name, logo and any phonetic variations. Brand names that are descriptive of metal (e.g. “SteelMax”) may face objections for being non-distinctive.
⏰ Time: 1–2 hours search + legal reviewDefine Your Class 6 Goods Precisely
Identify your exact products using NICE 13th Edition terminology. Be specific: “steel pipes and tubes; metallic pipe fittings; TMT steel bars; padlocks and door locks” is stronger than a vague description. If you also sell PVC or plastic products, add a Class 17 application. If you offer installation services, add Class 37.
📋 Specific descriptions = stronger protectionPrepare Required Documents
Gather: applicant identity proof (PAN + Aadhaar or incorporation certificate), business address proof, brand logo in JPG (minimum 300×300 px), Form TM-48 Power of Attorney if using an agent, and Udyam/DPIIT certificate to claim 50% fee concession. For regional hardware brands, prior use evidence like sales invoices boosts distinctiveness claims.
