Let’s dive in.
🧾 What Is Trademark Class 21?
Trademark Class 21 belongs to the Nice Classification System used in India and worldwide. It covers:
“Household or kitchen utensils and containers; combs and sponges; brushes (except paint brushes); brush-making materials; articles for cleaning purposes; steelwool; unworked or semi-worked glass (except building glass); glassware, porcelain and earthenware not included in other classes.”
If your business deals with glass kitchenware, storage containers, personal care brushes, or cleaning tools, Class 21 is the correct category for trademark registration.
📦 Products Under Class 21: Focus on Glassware, Brushes, and Containers
🔹 Glassware
- Glass bottles and jars
- Drinking glasses
- Vases
- Glass tumblers
- Glass pitchers
- Glass cookware (non-electric)
- Decorative glass items (not building glass)
🔹 Brushes
- Dishwashing brushes
- Clothes cleaning brushes
- Shoe brushes
- Hair and grooming brushes (non-electric)
- Toilet and bathroom brushes
- Brush-making materials (handles, bristles)
🔹 Containers
- Plastic and glass food storage boxes
- Airtight kitchen jars
- Lunch boxes and tiffins
- Storage bins (non-metallic)
- Spice containers
- Fridge organizers
🎯 Why Register a Trademark for These Products?
1. Protect Your Brand Name and Logo
Registering your brand name ensures no one else in your product category (Class 21) can legally use a similar name or logo.
2. Prevent Brand Imitation
Many businesses selling common items like jars or brushes risk duplication. A trademark gives you exclusive rights and the ability to take legal action.
3. Stand Out on E-commerce Platforms
Amazon, Flipkart, and Meesho require a registered trademark for brand registration, A+ listings, and brand protection.
4. Legal Proof of Ownership
A registered trademark is admissible in court if someone misuses your brand.
5. Build Trust and Long-Term Brand Equity
Consumers trust registered brands, especially in the household and personal care sectors.
📝 Step-by-Step: How to Register a Trademark in Class 21
Let’s look at the complete process.
🔍 Step 1: Conduct a Trademark Search
Before applying, search the Indian Trademark Registry to check if your brand name/logo is already taken.
Use the official tool:
👉 https://ipindiaonline.gov.in/tmrpublicsearch/frmmain.aspx
Search Tips:
- Check both wordmarks (names) and logos
- Use keyword variations (e.g., “GlassMate”, “Glass Mate”)
- Look for Class 21 matches only
If a similar trademark exists, rethink your name or consult a trademark expert to avoid legal trouble later.
🧾 Step 2: Prepare Your Application
You’ll need to submit Form TM-A, either online or physically. Before that, prepare the following:
✔ Product Description (with Class 21)
Clearly mention your product line.
Example:
“Trademark for glass kitchenware, airtight food containers, and non-electric household brushes under Class 21.”
✔ Choose What to Trademark:
- Wordmark (e.g., “GlassGlow”)
- Logo / Device mark
- Combination of both (recommended)
📋 Step 3: Collect Required Documents
| Document | Purpose |
| Applicant’s Name & Address | Individual, Company, or Firm |
| Brand Name / Logo | Wordmark or device mark |
| Product Description | Mention goods under Class 21 |
| Date of First Use | If already selling in the market |
| Power of Attorney (Form TM-48) | If filed through agent |
| MSME / Startup Certificate | To avail reduced fee (if eligible) |
| ID & Address Proof | Aadhaar, PAN, or Passport of applicant |
💻 Step 4: File the Application
You can file:
- Online at: https://ipindia.gov.in
- Offline at the nearest Trademark Registry Office (Mumbai, Delhi, Chennai, Kolkata, or Ahmedabad)
Ensure you:
- Select Class 21 correctly
- Upload the correct documents
- Pay the applicable fee
💰 Step 5: Pay the Trademark Fee
| Applicant Type | Fee per class |
| Individual / MSME / Startup | ₹4,500 |
| Company / Partnership / LLP | ₹9,000 |
📌 If you’re also registering under other classes (like Class 6 or Class 20), pay per class.
📩 Step 6: Get TM Number & Use ™ Symbol
Once the application is accepted, you receive a TM number within a day or two. You can now use the ™ symbol next to your brand name while awaiting final registration.
🧐 Step 7: Examination & Objection (if any)
The Trademark Office will examine your application for:
- Similar trademarks
- Correct classification
- Descriptiveness or generality of the name
Possible Outcomes:
| Status | Action |
| Accepted | Moves to Journal publication |
| Objected | Reply required within 30 days |
| Refused | Consider appealing or reapplying |
📣 Step 8: Journal Publication & Opposition Period
If accepted, your trademark will be published in the Trademark Journal for 4 months. During this time:
- Public can oppose (rare)
- If unopposed, it proceeds to registration
🎉 Step 9: Registration & Use of ® Symbol
Upon successful registration:
- You’ll receive the Trademark Registration Certificate
- You can legally use the ® symbol with your brand name
Your trademark is now valid for 10 years, and renewable indefinitely.
