Trademark Classes Explained: How to Choose the Right Class

Every trademark application filed in India requires you to select at least one class from a list of 45 categories. Pick the wrong class, and your trademark protects nothing. Pick too few, and a competitor can legally use your brand name for a product you forgot to cover. The Nice Classification system, now in its 12th Edition (2026), divides all goods and services into 34 goods classes and 11 services classes, and the Indian Trademark Registry follows this system under the Trade Marks Act, 1999 and Trade Marks Rules, 2017. This guide covers every class with examples, fees, and practical tips to help you file correctly.

What Is Trademark Classification? The Nice Classification System

Trademark classification is the system of organizing all possible goods and services into numbered categories for the purpose of trademark registration. India follows the Nice Classification, an international system established by the Nice Agreement (1957) and maintained by the World Intellectual Property Organization (WIPO). The current version, the 12th Edition effective from January 2026, is used by over 150 countries including India, the United States, the European Union, and the United Kingdom.

When you file a trademark registration application using Form TM-A on the IP India portal, you must select the class (or classes) that match your products or services. The Indian Trademark Registry, operating under the Controller General of Patents, Designs, and Trade Marks, uses these classes to examine your application, conduct searches for conflicting marks, and determine the scope of your trademark protection. A trademark registered in Class 25 (clothing) provides zero protection for your business if a competitor copies your brand name for use on electronics (Class 9) or food products (Class 30).

Goods classes cover physical, tangible products. Here is the full list with descriptions and common examples relevant to Indian businesses.

Complete List of 11 Services Classes (Classes 35 to 45)

Services classes cover intangible business activities. These classes matter for service-based businesses, consultancies, tech companies, and any company that does not sell a physical product.

Most Popular Trademark Classes for Indian Businesses in 2026

Not all 45 classes receive the same volume of applications. Based on IP India filing data and business registration trends, here are the classes that Indian startups and SMEs file most frequently.

Class 9: Technology and Electronics

Class 9 dominates startup filings because it covers mobile applications, downloadable software, computer hardware, and electronic devices. If your business builds any digital product that users download or install, Class 9 is mandatory. This includes SaaS products (the downloadable app component), mobile games, fintech payment apps, and IoT devices. The explosion of Indian tech startups has made Class 9 one of the top 3 filed classes every year since 2020.

Class 25: Clothing and Fashion

India's D2C fashion boom has pushed Class 25 filings to record numbers. This class covers all clothing, footwear, and headgear. Fashion brands on platforms like Myntra, Ajio, and their own websites file in Class 25. Remember: if you also sell accessories like bags (Class 18), sunglasses (Class 9), or jewellery (Class 14), you need those additional classes. A clothing brand filing only in Class 25 leaves its bag and accessories line unprotected.

Class 35: E-Commerce and Retail

Class 35 is the default for any business whose core activity involves retail, wholesale, or marketing of goods produced by others. E-commerce marketplaces, affiliate marketing businesses, franchise operations, and advertising agencies all file under Class 35. It is also needed for online retail stores that sell third-party products. If your company advertises, manages, or sells products on behalf of others, Class 35 is non-negotiable.

Class 42: IT Services and SaaS

Class 42 pairs with Class 9 for most tech businesses. While Class 9 covers the software product itself, Class 42 covers the services: cloud hosting, website design, software-as-a-service (SaaS) delivery, IT consulting, cybersecurity, and data analytics. If you charge subscription fees for cloud-based software, Class 42 covers that service delivery. India's IT services sector, valued at $254 billion in 2025, makes Class 42 one of the most competitive classes for trademark filing.

Class 43: Food Service and Hospitality

Restaurants, cloud kitchens, hotel chains, and catering companies file under Class 43. With India's food delivery market growing at 25% annually, cloud kitchen brands like Rebel Foods and EatFit have driven Class 43 filings upward. Remember: Class 43 covers providing food and drink as a service. If you also sell packaged food products (like bottled sauces or packaged snacks), you need Class 29 or 30 for the goods. A restaurant chain launching a retail sauce line without filing in Class 30 risks losing its brand name in the retail food space to a competitor who files first.

How to Choose the Right Trademark Class: 4-Step Process

Selecting the wrong class is one of the most common (and costly) mistakes in trademark filing. Here is a clear, step-by-step process to pick the right class before you file your TM-A application.

Step 1: List All Your Products and Services

Write down every product you sell and every service you offer, including those you plan to launch within the next 2 to 3 years. Be specific: do not just say "food business." Break it down: "packaged pickles" (Class 29), "restaurant dining" (Class 43), "cooking classes" (Class 41). Each distinct product or service may belong to a different class.

Step 2: Match Each Item to the Nice Classification

Use the search tools on ipindiaservices.gov.in or the WIPO Nice Classification database to find the exact class for each item on your list. Do not guess based on the class name alone. For example, "sunglasses" are not in Class 9 (electronics) under the heading you might expect; they are there because Class 9 includes optical apparatus. Always verify against the official classification list.

Step 3: Search Existing Trademarks in the Same Class

Before filing, run a search on the IP India Trademark Search portal. Enter your proposed trademark and filter by the class(es) you have identified. Check for identical marks, phonetically similar marks, and visually similar logos. If a conflicting mark exists, you risk a trademark objection (Section 9 or 11) or a trademark opposition from the existing owner. This search takes 15 minutes and can save you months of legal hassles.

Step 4: Plan for Future Business Expansion

Trademark protection is class-specific. If you file only in Class 25 (clothing) today but launch a perfume line next year, a competitor could register your brand name in Class 3 (cosmetics) before you do. Consider filing in additional classes now, especially if your business plan includes adjacent products or services. The extra cost of ₹4,500 per class is a fraction of the cost of losing your brand name in a new category.

Multi-Class Trademark Filing in India

India allows multi-class trademark applications, meaning you can file a single application covering 2 or more classes. This was enabled under the Trade Marks Rules, 2017, aligning India with international filing practices.

How Multi-Class Filing Works

You submit one TM-A form on the IP India portal with your trademark, but you list goods or services under multiple classes. The government fee is charged per class, not per application. So a 3-class application costs the same as filing 3 separate single-class applications. The advantage is administrative simplicity: one application number, one examination timeline.

Single-Class vs Multi-Class: Practical Considerations

While multi-class filing is convenient, there is a practical downside. If the Trademark Registry raises an objection in one class, it can delay the entire application across all classes. Some trademark attorneys recommend filing separate applications per class so that a problem in one class does not hold up registration in another. The cost is identical either way; only the administrative tracking differs.

Industry-Wise Class Recommendations

Choosing the right class depends heavily on your industry. Here is a ready-reference table for the most common business types in India.

Common Mistakes in Trademark Class Selection

Filing errors in class selection cost businesses time and money. Here are the most frequent mistakes and how to avoid them.

1. Relying on the Class Name Instead of the Full Description

Class names are only indicative. "Scientific apparatus" in Class 9 actually covers everything from fire extinguishers to mobile phone cases. Always check the full list of goods or services under each class in the Nice Classification database before deciding. A "health drink" might be Class 5 (if it is a dietary supplement) or Class 32 (if it is a non-alcoholic beverage). The distinction matters.

2. Filing in Only One Class When Multiple Are Needed

A clothing brand that also sells perfume, bags, and sunglasses needs at least 4 classes (25, 3, 18, 9). Filing in only Class 25 means competitors can register your brand name for perfume, bags, and eyewear. This is not a hypothetical risk; IP India records show thousands of identical marks across different classes owned by different entities.

3. Ignoring Services When You Are a Product Company

A software company that files only in Class 9 (software product) but ignores Class 42 (IT services) leaves its SaaS delivery, consulting, and maintenance services unprotected. If your business offers any service alongside its product, file in the corresponding services class.

4. Selecting the Cheapest Option Instead of the Right Classes

Some applicants file in just one class to save ₹4,500 per additional class. This short-term saving often leads to long-term brand vulnerability. The cost of a trademark opposition or infringement suit can run into lakhs. Filing in 2 to 4 classes at the start, costing ₹9,000 to ₹18,000, is far cheaper than litigation.

5. Failing to Plan for Business Expansion

Your business today may sell only clothing, but your brand roadmap might include home decor, fragrances, or lifestyle accessories. Filing in future categories now (even before launching those products) secures your brand name in those spaces. You have 5 years to demonstrate use after registration.

Trademark Class and the Filing Process on IP India

Understanding how class selection fits into the filing workflow ensures you get it right from the start.

Step-by-Step Filing Process with Class Selection

1. Conduct a Trademark Search: Search the IP India database by class. Filter results by your selected class(es) to check for conflicting marks
2. Prepare TM-A Application: The Form TM-A requires you to select the class number and provide a description of goods or services as per the Nice Classification
3. Pay Class-Wise Fees: For each class selected, pay ₹4,500 (individuals/startups) or ₹9,000 (others) online via the IP India portal
4. Trademark Examination: The examiner reviews your application class by class. An objection may be raised under Section 9 (absolute grounds) or Section 11 (relative grounds, i.e., conflict with existing marks in the same class)
5. Publication in Trademark Journal: If accepted, the mark is published with class details. Existing trademark holders in the same class may file an opposition within 4 months
6. Registration Certificate: If no opposition is filed (or opposition is dismissed), the Registrar issues a registration certificate specifying the protected class(es)

Well-Known Trademarks: Cross-Class Protection

While most trademarks are protected only within the class(es) they are registered in, there is an important exception for well-known trademarks that every brand owner should understand.

Under Section 11(6) of the Trade Marks Act, 1999 read with Section 2(1)(zg), a well-known trademark receives protection across all 45 classes, even if it is registered in only one or a few. This means no other party can register a similar mark in any class if it is likely to cause confusion with a well-known mark. The Trademark Registry considers factors like the duration of use, geographical extent, volume of sales and advertising, and consumer recognition when assessing well-known status.

The Trademark Registry maintains a list of well-known trademarks on the IP India website. Examples include TATA, Reliance, Infosys, Amul, Flipkart, and international marks like Apple, Nike, and Google. To have your trademark declared well-known, you must file a petition before the Registrar or a court, demonstrating extensive use, consumer recognition, and reputation across India. As of 2026, over 200 marks have been declared well-known by the Indian Trademark Registry.

For most startups and SMEs, well-known status is not achievable in the early years. This is precisely why filing in multiple classes is critical: multi-class registration is the primary defense for brands that do not yet qualify for cross-class well-known status. Do not rely on the "well-known" exception as your brand protection strategy unless you have a decade of market presence and nationwide recognition.

Trademark Classes and Copyright Protection: Know the Difference

Business owners sometimes confuse trademark classes with copyright protection. These are two distinct IP rights.

If you have a unique logo, consider both trademark registration (to protect it as a brand identifier) and copyright registration (to protect the artistic work itself). Both protections complement each other and strengthen your IP portfolio.

Summary

Trademark class selection is not a formality; it defines the exact scope of your brand protection under Indian law. The 45 classes under the Nice Classification (12th Edition, 2026) cover every conceivable product and service. Indian businesses typically need 2 to 4 classes for meaningful protection, with Class 9, 25, 35, 42, and 43 being the most popular. Filing costs start at ₹4,500 per class for DPIIT-recognized startups and ₹9,000 for other entities. Get your class selection right the first time because changes after filing are not allowed, and a wrong class means starting over with a fresh application and new fees.
