Trademark Classification Explained: The Nice System

Every trademark application in India has to specify a class, and getting it right shapes what the registration actually protects. This post covers the system itself — how it's structured, how classification decisions are actually made, and how to find the classes relevant to a specific business. For what a specific class covers in detail, see our growing series of individual class guides, starting with Class 25 and Class 35.

What the Nice Classification Is

The Nice Classification is an international system for categorising goods and services for trademark registration purposes, administered by the World Intellectual Property Organization and adopted by IP India, among most national trademark offices worldwide. It's periodically revised — new editions are published every few years, with smaller updates in between — so the exact scope of a class can shift slightly over time as new categories of goods and services (digital products, for instance) get formally incorporated.

The 45-Class Structure

The system splits cleanly into two halves:

This goods/services split matters beyond just organisation — it's the reason a business that both manufactures a product and sells it through its own retail channel often needs two separate classes: one from the goods side (1–34) for the product itself, and one from the services side (35–45) for the retail activity. We covered this exact pattern in our Class 35 deep-dive.

How Classification Actually Works

Each class has an official heading — a short, broad summary — and a detailed explanatory note describing what it includes and excludes. Beneath that sits an alphabetical list of thousands of specific goods and services, each assigned to a class based on its essential nature or function, not just what it sounds like it should be.

When something new doesn't appear explicitly in the alphabetical list — a new type of digital product, for instance — it gets classified by analogy: comparing it to similar, already-classified items and placing it in the class that fits best by function, not by guesswork.

Why the Headings Alone Can Mislead

Class 35 is the clearest example of this on the site — its heading is "advertising; business management; business administration; office functions," but its alphabetical list includes things like typing, photocopying, and personnel recruitment: services that don't obviously scream "advertising" at first glance, but which fit the class's underlying logic of commercial and administrative assistance. This is exactly why relying on a class heading alone, without checking the actual scope, leads to the kind of misclassification we've covered in individual class posts — assuming Class 25 covers bags (it doesn't, that's Class 18), or assuming Class 35 covers your product itself (it doesn't, that's a separate goods class).

Filing in Multiple Classes

Indian trademark applications can cover more than one class in a single Form TM-A filing — it doesn't require separate applications. Running a free trademark search across all the classes you plan to file in before submitting is worth doing, since the government fee is charged per class and is non-refundable. What it does require is a separate government fee for each class included, since the fee is charged per class, not per application. A business that needs both a goods class and a services class pays for both, within one filing.

How to Identify Your Classes

A practical approach, rather than guessing from the class headings alone:

• List every genuinely distinct product or service the business offers, not just the primary one
• For each, ask whether it's a physical good (Classes 1–34) or an activity performed for others (Classes 35–45)
• Check the specific class's explanatory note and alphabetical list, not just the heading, since headings can undersell or mislead
• Use our free trademark class finder to get a recommendation based on your actual business description
