The latest edition of the Nice Classification, the international system used to classify goods and services for trade mark registration, entered into force on 1 January 2026.
It introduces important changes across several key sectors, including artificial intelligence, eyewear, clothing, travel and beauty.
Rightsholders should ensure that their goods and services are correctly classified under the updated system. The changes may influence filing strategies, clearance exercises and long‑term portfolio planning. Misclassification can have real consequences, from examination delays to gaps in protection.
Below is a summary of the key changes.

- Essential oils for fragrancing or cosmetic use are in Class 3.

- Essential oils for use in manufacture are in Class 1.
- Emergency and rescue vehicles are moved from Class 9 to Class 12.
- Electrically heated clothing has moved from Class 11 to Class 25.
- Yoga‑related goods must be classified according to their nature.
- Yoga blocks are in Class 28.

Services
