Class 4 trademark for oils, fuels and candles
Short answer
Class 4 covers industrial oils and greases, lubricants, fuels and illuminants, and candles and wicks, including scented candles. You file in class 4 when you sell these goods under your brand; most offices charge an official fee per class.

- lubricants
- fuel

- industrial oils
Official class heading, Nice Classification 12th edition
Industrial oils and greases, wax; lubricants; dust absorbing, wetting and binding compositions; fuels and illuminants; candles and wicks for lighting.
Often filed in class 4 by mistake
Filing in the wrong class leaves your real products unprotected and still costs the class fee. These belong elsewhere.
Typical conflicts for class 4 marks
Candle brands often clash with home fragrance and essential oil marks in class 3, while lubricant and fuel marks meet chemical marks in class 1.
An office compares your mark with earlier marks for identical and related goods or services, not only within the same class. Run a trademark availability search to see the closest marks in class 4 and its neighbours, or order a clearance search before a launch.
