The Department of Intellectual Property (DIP) of Thailand has announced the reclassification of certain goods under the 13th Edition of the Nice Classification, (NCL 13), which will take effect in 2026. This update aligns Thailand’s trademark classification system with the latest international standards and may affect both pending and future trademark applications.

 

Key changes include the transfer of several product groups to new classes, including:

  • Eyewear and lenses: Eyeglasses, sunglasses, contact lenses, frames, and related accessories will be reclassified from Class 9 to Class 10.
  • Safety and rescue equipment: Fire engines, fire boats, lifeboats, life rafts, and evacuation chairs will be reclassified from Class 9 to Class 12.
  • Electrically heated clothing and accessories: Heated garments, heated socks, and electrically heated footmuffs will be reclassified from Class 11 to Class 25.

 

The DIP also announced reclassification for several individual goods, including: terpenes, which will move from Class 3 to Class 1; tongue scrapers, from Class 10 to Class 21; watering hose nozzles, from Class 21 to Class 17; surf skis, from Class 28 to Class 12; and buttercream (icing), from Class 29 to Class 30.

 

According to the DIP’s announcement, applicants who file the trademark application before 31 January 2026 may continue using the existing classification. However, once the marks are registered, the new class positions under NCL 13 will apply upon renewal. Trademark owners are therefore advised to review their current trademark portfolios and upcoming filings to ensure that goods are correctly classified under the revised system, so as to avoid procedural issues and ensure continuous protection.
