JTJB International Lawyers Co., Ltd. would like to inform our clients and business partners that the Department of Intellectual Property of Thailand (DIP) has officially updated its trademark classification practice by adopting the Nice Classification, 13th Edition, which will take effect in 2026.

Under the 13th Edition of the Nice Classification, several goods and services have been reclassified to better reflect current commercial and technological developments, as well as to align Thailand’s practice with international trademark standards. Notably, certain categories of goods have been transferred to new classes, such as eyewear-related products moving from Class 9 to Class 10, emergency and rescue vehicles from Class 9 to Class 12, and electrically heated clothing and accessories from Class 11 to Class 25. Additional goods have also been reallocated across various classes under the revised classification framework.

These changes may have practical implications for trademark owners, particularly in relation to new trademark filings, amendments to pending applications, and the scope of protection of existing trademark registrations. Accurate classification of goods and services will be increasingly important to avoid procedural issues, potential objections, or unintended limitations on trademark rights.

We, therefore, recommend that trademark owners review their existing trademark portfolios and future filing strategies in light of the implementation of the Nice Classification, 13th Edition. A proactive approach will help ensure continued compliance with the updated requirements and maintain effective trademark protection in Thailand.

Please contact our Intellectual Property team at JTJB International Lawyers Co., Ltd. for further advice, portfolio review, or assistance with trademark filings and amendments under the updated Nice Classification.

We remain pleased to support our clients in navigating these regulatory developments and in safeguarding their valuable intellectual property rights.
