Key takeaways
- Mexico requires every trademark application filed with the Mexican Institute of Industrial Property (IMPI) to identify goods and services using the 45 international classes of the Nice Classification.
- Classes 1–34 cover goods and classes 35–45 cover services; the classes you choose define the scope of your trademark protection in Mexico.
- Choosing correctly means mapping your actual products or services and checking them against IMPI’s official tools, ClasNiza and the Marcanet validator.
- Filing in the right class(es) reduces legal conflicts and supports commercial use, licensing and the valuation of intangible assets.
- Common mistakes include vague descriptions, choosing classes based on a broad industry label and failing to extend protection as the business grows.
Why the Nice Classification matters when registering a trademark in Mexico
For any company planning to sell under its brand in Mexico, the Nice Classification is where trademark protection starts. According to the
World Intellectual Property Organization (WIPO), the Nice Classification is an international system used by more than 150 countries, including Mexico, to organize goods and services into 45 classes. In Mexico, it is mandatory in every trademark filing with IMPI and determines the scope of legal protection each mark receives.
Whether you are launching products in Mexico, licensing your brand to a local partner or managing a portfolio of intangible assets, choosing the right classes helps you avoid refusals, limit legal risk and build a sound IP strategy. This guide covers what the Nice Classification is, how Mexican law applies it, a practical method for choosing your classes and the most common mistakes.
What is the Nice Classification?
The Nice Classification comes from the Nice Agreement (1957), an international treaty administered by WIPO that sets out 45 classes for goods and services in trademark registration, as explained in the
official preface to the Nice Classification. Classes 1 to 34 cover goods (food, electronics, clothing and more), while classes 35 to 45 cover services such as retail, consulting, education and technology.
Because the system is international, class numbers are the same in Mexico as in other member countries. What changes is how each application is prepared: every trademark filing in Mexico must identify the relevant class or classes, and IMPI offers
ClasNiza, its official search tool, to locate the right class and the accepted description for each product or service. Choosing the wrong class can narrow your protection or lead IMPI to refuse the application. If you are still unsure whether you need a trademark, a patent or copyright, see our overview of
trademarks, patents and copyright in Mexico.
Legal framework: how Mexican law applies the Nice Classification

The Mexican Federal Law for the Protection of Industrial Property (LFPPI) requires every trademark application to specify goods or services according to the Nice Classification, and it gives IMPI authority to resolve any doubts about which class applies. The classification is updated regularly, so it is worth confirming the current version before filing.
Mexico currently applies the NCL 13-2026 version of the Nice Classification, which means checking the annual updates to make sure you are working with the latest list. This matters because the class defines the scope within which your trademark can be used, enforced and exploited. The same rules apply to foreign companies filing in Mexico; our guide to
trademark protection in Mexico for foreign companies explains the wider process.
How to choose the right trademark classes in Mexico: a practical method
1. Map the goods or services you actually offer
Start by identifying exactly what you sell or which services you provide, covering both current activities and your plans for the next two to three years. Many companies confuse their broad line of business with the specific goods or services they offer, which can lead to incomplete or unnecessary registrations. If you already hold registrations in other countries, use them as a starting point, but confirm that the goods and services listed reflect what you will actually offer in the Mexican market.
2. Decide whether they are goods or services
Classes 1 to 34 are reserved for goods, while classes 35 to 45 cover services. If your company manufactures or sells products, start with the goods classes; if it provides services, go to the service classes. For example, a business consulting firm should look in class 35 (business management consulting), while a processed food brand will usually fall under class 29 or 30, depending on the product.
This analysis is the first step in any
trademark registration and enforcement strategy in Mexico: if the class does not reflect what you actually sell, your mark may end up with limited protection or exposed to conflicts with third parties.
3. Check your terms against IMPI’s official tools
IMPI offers two online tools for this step:
Both tools work in Spanish, so foreign applicants often rely on local counsel and
specialized IP legal translation to match their product descriptions to the accepted terms. Working with these platforms reduces the risk of office actions and keeps the application aligned with IMPI’s current criteria.
4. Plan for reasonable growth in Mexico
Consider filing in classes that cover your current goods or services and those you plan to offer in the coming years. Including planned activities from the start avoids additional costs and filings later. On the other hand, claiming overly broad or unrelated classes is not advisable: it can trigger objections and, later on, cancellation of the registration for non-use.
5. Assess whether you need multiple classes
If your offering spans several areas, you will likely need protection in more than one class. Technology companies are a typical example: they often file in class 9 (software), class 42 (software development or technology consulting) and, if they sell online, class 35 (retail of technology products).
Common mistakes when choosing Nice classes
- Using vague or marketing-driven wording instead of the official Nice Classification terms.
- Choosing a class that does not match the actual activity, such as filing for a service when the mark should have covered a product.
- Failing to file new applications when the business adds goods or services that belong to other classes.
- Including goods or services you do not use and will not use, which puts the registration at risk for non-use.
Getting the classes right at filing is far easier than fixing them later. If you are unsure which classes fit your business,
schedule a consultation with BE IP.
How class selection shapes licensing, franchising and valuation

The classes you choose determine against whom, for which goods or services and in what situations you can enforce your trademark rights in Mexico. They also shape licensing and royalty negotiations, franchise structures and the
tax and accounting valuation of your intangible assets. A well-segmented trademark portfolio supports clear agreements with Mexican distributors, licensees or franchisees, and lets you treat your brand as what it is: a business asset, not just a filing.
For example, if you register your mark for technology products (class 9) and consulting services (class 42), you can license each business line on different terms and get more value from your intellectual property.
Quick checklist for choosing your Nice classes
- Determine whether your main activity is selling goods (classes 1–34) or providing services (classes 35–45).
- List every specific product or service you offer or plan to offer in Mexico within two to three years.
- Use ClasNiza and the Marcanet validator to identify the exact class(es) and official terms.
- Decide whether one class is enough or you need several, based on your business model and sales channels.
- Confirm that classes and descriptions match your real operations, growth plans and the corporate structure of the company that will own the mark.
If you already own trademarks in Mexico, or are about to acquire a Mexican company, an
IP audit and due diligence review lets you check whether the portfolio covers every business line and spot gaps before a third party takes advantage of them.
FAQs about the Nice Classification in Mexico
How do I file a trademark with IMPI using the Nice Classification?
Define the goods and services you want to protect, locate their class in
ClasNiza, draft the application using the official terms and pay the official fees for each class. To budget the process, see our breakdown of
trademark registration costs in Mexico.
How long does trademark registration take in Mexico?
The IMPI process usually takes 4 to 6 months. A well-chosen class and a precise description of goods or services reduce the chance of office actions that delay the process.
Can I oppose someone using my trademark in a different class?
Trademark protection centers on the registered goods or services, but the class number alone does not decide likelihood of confusion. What matters is whether the goods or services are identical, similar or related, even if they fall under different classes. That is why an opposition can succeed against an application in another class when that relationship exists.
How does the right Nice class protect against conflicts or misuse?
Registering in the correct class lets you take legal action against third-party infringement, because it clearly defines the scope of your trademark protection in Mexico. And since the Nice Classification is international, a well-drafted description makes it easier to extend protection to other countries.
Can IMPI refuse my application if the class is wrong?
Yes. IMPI can issue an office action requiring you to correct the class or the description of goods or services and, if the issue is not resolved, refuse the application.
