Things burnt for energy or light, and things used to reduce friction — engine oil, grease, industrial lubricants, fuels, wax and candles.
Below: the official class heading, 5 kinds of business that file here, 4 things that get filed here by mistake and where each actually belongs, the 3 classes usually filed alongside class 4, and all 45 classes in one table.
As published in the Nice Classification, the WIPO list the Indian register is organised on.
Industrial oils and greases, wax; lubricants; dust absorbing, wetting and binding compositions; fuels and illuminants; candles and wicks for lighting.
Transcribed from the Nice Classification (11th edition). WIPO revises these headings between editions, and a heading describes a class rather than closing the list of what falls in it — the Registry's own list of goods and services is what governs a filing.
Concrete enough to recognise yourself in, or to rule yourself out. These are our judgements, not the Registry's.
Each of these belongs in a class of its own, linked. Getting it wrong is not fatal, but it is slow and it is paid for twice.
The first cut in the whole system, and the one that decides half of all misfilings.
Classes 1 to 34 are goods — things somebody makes and somebody else owns afterwards. Classes 35 to 45 are services — things somebody does. Class 4 is on the goods side, which means a registration here covers the article you sell and not the service you perform around it. Selling it in your own shop, making it to somebody else's order, delivering it, teaching people to use it — those are separate classes on the other side of the line.
Neighbouring numbers are not neighbouring businesses. The classification was assembled over decades and its order is historical, so class 4 sits beside class 3 and class 5 for reasons that have nothing to do with what a modern company sells. Read down the table at the foot of this page rather than around a number.
The single most expensive misunderstanding in Indian trademark filing.
A trademark registration is a right in the classes named on it. Registering in class 4 gives you nothing in the other 44: the identical name remains available to somebody else in every class you did not file, and they can register it there. This is not a loophole — it is the design. The classification exists precisely so that the same word can belong to a shoe company and to a software company at once.
Read the other way it is the reassuring half. A mark already registered in a class unrelated to yours generally cannot stop you using the name in yours, which is why a search that comes back with hits is not automatically a dead end — what matters is whether the hits are in your class and near your goods. Well-known marks are the exception the system writes for itself, and whether a mark is well known is a finding the Registry makes, not something read off a list.
The practical consequence is that the classes you file describe the business you intend to be, not only the one you are. Extending into a class later means filing later — at that day's queue, and against whatever has been registered in the meantime by somebody who read this page sooner.
General information, not legal advice. This page explains how the classification system is organised. It is not advice about your filing: which class or classes a mark belongs in depends on the goods and services you actually supply, and the specification is drafted word by word, not chosen off a list. Have a trademark attorney confirm the classes and the wording before you file. We publish no filing fees anywhere on this site — they are set by the Registry and revised from time to time, and we have no verified source for them, so take them from the Registry's own schedule.
Why each one comes up. Our judgement, from the way these businesses are actually built.
| Class | Covers | Why it comes up with class 4 |
|---|---|---|
| Class 1 | Industrial and agricultural chemicals | Additives, coolants and the chemicals sold beside a lubricant range are class 1. |
| Class 35 | Advertising, retail and business services | Lubricants live or die on a dealer network, and running that network is retail rather than manufacture. |
| Class 37 | Construction, installation and repair | Servicing, lubrication and maintenance done for a customer is a class 37 service under the same brand. |
Classes that sit in the same part of the classification as class 4.
A class is one queue. The address is another, and it is the one that goes on the packaging.
A registration in class 4 covers fuels, lubricants and candles on the register. It reserves no address, no handle and no listing — those are first-come queues run by people who have never heard of the Nice Classification.
A trademark class and a domain name have nothing to do with each other, and each is regularly mistaken for the other. Registering a domain creates no trademark right of any kind — the registrar sells you a rental on an address and makes no enquiry into who else uses the name. A trademark registration, equally, reserves nothing at any registry: the matching address can be bought by anyone while your application sits in the queue.
Which is why the practical order is to check both before printing anything. Across the 14 endings we price, the range runs from .xyz at ₹249 to .ai at ₹15,400. Five of them, and what each costs for a first year:
Indicative first-year prices from our own table, not a registrar quote, and not an availability answer — whether a particular name is free is a question only a live lookup can settle. Each ending has its own page with who it suits and how the check works.
Things burnt for energy or light, and things used to reduce friction — engine oil, grease, industrial lubricants, fuels, wax and candles. The Nice Classification heading for class 4 reads: Industrial oils and greases, wax; lubricants; dust absorbing, wetting and binding compositions; fuels and illuminants; candles and wicks for lighting.
Goods. Classes 1 to 34 cover goods and classes 35 to 45 cover services, and class 4 is the 4th of the 34 goods classes. The distinction matters more than it looks: the thing you sell and the service you perform around it are different classes even when they carry the same name, which is why a manufacturer that also runs a shop, or a studio that also sells a product, ends up on both sides of the line.
No. A registration is a right in the classes it names and nowhere else, so a mark registered in class 4 leaves the same name available to somebody else in the remaining 44. The rule read the other way is the useful half: a mark somebody else holds in a class unrelated to yours generally cannot stop you, which is how identical names co-exist across unrelated industries. Well-known marks are the exception the system carves out for itself, and whether a mark is well known is decided by the Registry rather than by the class list.
Candles and wicks for lighting are named in class 4. The fragrance oil is class 3. Home-fragrance brands that sell candles, reed diffusers and room sprays usually end up in both, because the range crosses the line the classification draws.
Not class 4. Fuels are goods; supplying electricity as a service is not, and the charger itself is apparatus in class 9. Class 4 is for the litre in the drum, not the current in the cable.
No, and no static page can. This file was built ahead of time and serves the same bytes to everyone, while applications and registrations move daily. The register is maintained by the Office of the Controller General of Patents, Designs and Trade Marks, and its public search is free to use — this page is for working out which class to search in, which is the question that has to be answered first.
The whole classification, goods first. The same table appears on every class page, so whichever one you landed on carries the full picture.

One search runs the domain endings, the social handles and the marketplace listings together, so you find out the name is gone before the specification is drafted rather than after.
