Trademark Class 4: Fuels, Lubricants & Industrial Oils – Complete Guide

Are you dealing in fuel products, industrial lubricants, or even manufacturing candles? Trademark Class 4 is the correct classification for protecting your brand under Indian trademark law. This class is crucial for businesses involved in the energy, industrial, and automotive sectors.

Trademark Class 4 covers a broad category of energy and oil-related products, including:

• Industrial oils and greases
• Lubricants for machinery and engines
• Dust absorbing, wetting, and binding compositions
• Fuels, including petrol, diesel, kerosene, and other motor spirits
• Illuminants (e.g., lamp oils)
• Candles and wicks for lighting

Whether you're in the petroleum industry or you make eco-friendly candles, Class 4 protects your branding.

Registering under Class 4 provides:

• Exclusive rights over your brand identity in the fuel, lubricant, and lighting product sectors
• Legal recourse against counterfeit or infringing brands
• Market credibility in regulated industries
