On January 26, 2026, Vietnam’s Ministry of Finance issued Circular No. 06/2026/TT-BTC (Circular 06), amending and supplementing Circular No. 13/2015/TT-BTC, which provides guidance on dossiers and procedures for customs recordal and customs supervision in relation to intellectual property rights (IPR). Circular 06 has an effective date of March 1, 2026. Some notable points of Circular 06 include the following: Simplified Documentation for Customs Recordal Applications Circular 06 reduces some documentary requirements for IPR owners: A power of attorney is no longer required to be legalized. Applicants are no longer required to submit title or registration certificates if such documents are issued in digital form. In such cases, it is sufficient to declare comprehensive information on the relevant IPR, enabling customs authorities to verify the information through publicly accessible databases. In practice, this amendment is particularly beneficial for international trademark registrations designating Vietnam. IPR owners may no longer need to obtain a confirmation letter from the Intellectual Property Office of Vietnam regarding the validity of a trademark registration in Vietnam. Instead, they may rely on registration status information available from the World Intellectual Property Organization (WIPO) database, reflecting that the international registration has been granted protection in Vietnam. Clearer Mechanism for Ex Officio Suspension of Suspected Infringing Goods Although ex officio suspension has been referenced in earlier regulations, Circular 06 provides clearer guidance on the circumstances and procedures under which customs may proactively suspend customs procedures for consignments suspected of being counterfeit or pirated goods. Accordingly, customs authorities may initiate the suspension of clearance without waiting for a formal request from IPR owners. Enhanced Supervision of Imported/Exported Goods in E-Commerce Circular 06 also supplements provisions on the inspection of imported and exported goods transacted through e-commerce channels. Customs authorities may apply risk management measures to assess goods traded via e-commerce

Thailand is preparing to offer new tools for intellectual property enforcement as the Electronic Transactions Development Agency (ETDA) recently released for public consultation a draft notification requiring social media platforms to verify user identities and conduct know-your-customer (KYC) checks on advertisers. The draft Notification of the Electronic Transactions Commission on Measures to Prevent Technological Crimes for Social Media Service Providers, which is to be issued under the Emergency Decree on Measures for the Prevention and Suppression of Technological Crimes B.E. 2566 (2023), as amended in 2025, primarily aims to combat online fraud and technology-related crimes. However, its new obligations also provide IP owners with valuable tools to identify anonymous infringers. Key Regulatory Mandates The draft notification imposes several verification requirements on social media platforms operating in Thailand. These requirements also strengthen IP rights holders’ ability to identify anonymous infringers, as platforms must: Verify user identities through registered phone numbers and link all accounts to verifiable identities. Conduct KYC checks on advertisers, including individuals, companies, and any third-party payers. Perform heightened identity checks for high-risk or repeat offenders before publishing advertisements. Promptly remove content flagged by the Anti-Technology Crime Division and prescreen advertisements for prohibited or high-risk content. How IP Owners Can Use This Notification for Enforcement The phone number–based verification requirement enables IP owners to work more effectively with enforcement authorities in tracing individuals or entities responsible for infringing content. The comprehensive advertiser KYC obligations, including mandatory disclosure of third-party payment sources, create a clear audit trail even when bad actors attempt to obscure their identity through intermediaries or shell accounts. This traceability is essential for pursuing damages and dismantling organized counterfeit operations. The ETDA is now considering adjustments to the draft notification after receiving comments during the public consultation period, which ended on February 2, 2026. Following finalization

On December 26, 2025, the government of Vietnam promulgated Decree No. 341/2025/ND-CP on administrative sanctions for violations of copyright and related rights (Decree 341), with an effective date of February 15, 2026. The new decree replaces Decree No. 131/2013/ND-CP, as amended, and represents the first comprehensive revision of the administrative enforcement framework in this area in eight years. Legislative Context and Objectives Decree 341 reflects Vietnam’s evolving copyright and related-rights framework, particularly in light of the country’s commitments under bilateral, regional, and multilateral treaties governing the digital environment. While the decree retains a number of provisions from the previous regime, it also introduces significant amendments to infringing acts, penalty thresholds, remedial measures, and enforcement procedures. The primary objectives of the new decree are to (i) enhance the deterrent effect of administrative sanctions; (ii) harmonize sanctions with the 2025 amendments to the Law on Intellectual Property and criminal law principles; and (iii) address enforcement challenges arising from online and cross-border exploitation of copyrighted works. Expanded Scope of Sanctionable Subjects Under Decree 341, administrative sanctions apply not only to Vietnamese entities committing infringing acts within Vietnam, but also to Vietnamese and foreign entities that commit acts of infringement on the internet where the protected content is accessed, consumed, or exploited by users in Vietnam. This expansion reflects the realities of cross-border digital exploitation. However, the decree does not yet provide precise definitions of key terms such as “users” or “consumers” of digital content in Vietnam, which may require further regulatory clarification. Monetary Penalties and Penalty Structure The statutory maximum fines remain unchanged, at VND 250 million for individuals and VND 500 million for organizations, but the penalty framework is substantially restructured. Fines are now calibrated based on three core criteria: (i) the amount of illegal profit obtained; (ii) the level of
