Trademark classes are the 45 categories of the Nice Classification that the INPI (Argentina’s National Institute of Industrial Property) uses to organize all goods and services: 34 classes of goods and 11 classes of services. Your trademark is not registered “in general”: it is registered in specific classes, and it is protected only in the ones you chose.
Choosing the wrong class is one of the costliest mistakes in the registration process: you can end up paying for protection that does not cover your actual business. Here is how the system works, which classes are used most in Argentina, and how to decide which ones you need.
How the Nice Classification works in Argentina
The INPI applies the International Nice Classification, the standard used by the trademark offices of most countries. Every trademark application is filed in one or more classes, a fee is paid for each class, and protection extends only to the goods or services in the classes granted.
This has a direct consequence: two identical trademarks can lawfully coexist if they operate in different classes and do not create confusion. The same name can be a clothing brand (class 25) and an accounting firm (class 35) without any conflict.
Trademark classes for goods (1 to 34): the most used in Argentina
The first 34 classes cover physical goods. These are the ones registered most often:
- Class 25: clothing, footwear and headwear. The class for every clothing brand.
- Class 30: coffee, tea, flour, baked goods, alfajores (Argentine filled cookies) and candy.
- Class 32: beer, water and non-alcoholic beverages. The class for craft breweries.
- Class 33: alcoholic beverages except beer: wine, fernet, gin.
- Class 29: meat, dairy products, preserved foods, snacks.
- Class 3: cosmetics, perfumery and cleaning products.
- Class 9: downloadable software, apps and electronic devices.
- Class 5: pharmaceutical products and supplements.
Trademark classes for services (35 to 45): the most used
The last 11 classes cover services. The most frequent ones:
- Class 35: advertising, business management and retail/wholesale services. The catch-all class for commerce, and one of the most contested.
- Class 41: education, training and entertainment.
- Class 42: software development and technology services (software as a service goes here, not in class 9).
- Class 43: food service and hospitality: restaurants, cafés, bars.
- Class 44: medical, beauty and veterinary services.
- Class 36: financial, real estate and insurance services.
- Class 39: transportation and logistics.
- Class 45: legal services.

The mistake that costs the most protection: registering in only one class
The typical case: a brewery registers its trademark in class 32 (beer) but not in class 43 (bar services). A third party opens a bar under the same name, and the conflict is much harder to resolve than if the trademark covered both classes.
The right question is not “What do I sell today?” but “Where does my brand live, and where is it heading?” If you sell clothing (class 25) through your own online store with your brand displayed on the store (class 35) and you plan to open physical stores, that map defines your classes. Each class adds a fee, so the balance between coverage and budget is decided case by case. That is exactly the analysis we carry out before filing a trademark application.
How to know which class to register your trademark in
The Nice Classification search tool lets you search by term, but the fine print matters: some goods intuitively seem to fall in one class but belong to another (downloadable software is class 9; software as a service is class 42).
Before defining your classes, it is also wise to check that the name is available in those classes.
And if your trademark combines a name and a logo, the type of mark also affects the strategy.
Frequently asked questions about trademark classes
The Nice Classification has 45 classes: classes 1 to 34 cover goods and classes 35 to 45 cover services. It is the international standard applied by the INPI in Argentina, and every trademark application is filed in one or more of those classes.
Legally, yes, but each class carries its own fee, and a registration in classes where the trademark is not used may become vulnerable to petitions for cancellation for non-use. The right strategy is to cover the classes of your current business and its reasonable expansion.
Protection applies only in the classes granted: if your actual business falls in another class, the trademark does not cover it. A registration cannot be “moved” to a different class; you need to file a new application in the correct class, first checking that the name is still available there.
Yes, it is a common situation: the same name can be registered by different owners in classes that do not compete with each other. The limit is consumer confusion: if the classes are related or one of the trademarks is well known, coexistence is no longer peaceful.
Defining the right classes is half of a well-executed registration. Tell us what your brand does and we will tell you which classes to file in. Your first consultation is free.
