On July 24, 2026, a new 12.5% Section 301 tariff took effect on most imports from Thailand into the United States. The tariff was imposed by the Office of the US Trade Representative (USTR) under Section 301 of the Trade Act of 1974, following a finding that Thailand had failed to impose and effectively enforce a prohibition on imports of goods produced with forced labor. The new tariff replaced the temporary 10% Section 122 surcharge that had applied since February 24, 2026, following the US Supreme Court’s invalidation of the prior tariffs imposed under the International Emergency Economic Powers Act (IEEPA). The 12.5% tariff is not the only potential source of additional US duties on Thai-origin goods. Thailand is also subject to a separate Section 301 investigation concerning structural excess manufacturing capacity, which could result in additional duties. Unlike the Section 122 surcharge, which was capped at 15% and limited to 150 days, Section 301 provides a more flexible framework for imposing and maintaining trade measures. Section 301 actions are generally subject to a four-year termination rule but may continue following a review if continuation is requested. The new tariff therefore represents a potentially longer-term change in the tariff treatment of Thai-origin goods entering the US market. This article explains the legal and policy developments that led to the new tariff, how the Section 301 tariff differs from the tariff regimes that preceded it, Thailand’s response and ongoing negotiations with the United States, and the practical implications for businesses that manufacture, export, import, or distribute goods between Thailand and the United States. From IEEPA to Section 122 to Section 301 IEEPA Era (April 2025–February 2026) Beginning in April 2025, the US administration imposed sweeping tariffs under the International Emergency Economic Powers Act (IEEPA), invoking national emergencies relating to trade

On September 15, 2026, Vietnam’s Ministry of Finance (MOF) released for public consultation a draft circular on reporting and information disclosure in the pilot crypto asset market. The draft implements Resolution No. 05/2025/NQ-CP on the Pilot Implementation of the Crypto Asset Market in Vietnam and provides further detail on how licensed crypto asset service providers (“CASPs”) will be supervised once the market becomes operational. The draft indicates a data-intensive supervisory model, with licensed CASPs serving as the first line of market oversight. Public Disclosure Requirements The draft imposes detailed public disclosure requirements on CASPs, aimed primarily at market transparency. CASPs and crypto asset issuers must make disclosures in both Vietnamese and English, retain reported and disclosed information for at least 10 years, and keep information published on their websites accessible for at least five years. For CASPs, disclosure obligations arise both periodically and when specific events occur. A CASP must announce any crypto asset to be admitted to trading on its website at least seven days before trading begins and publish periodic financial statements. Certain extraordinary events and information requested by the MOF must generally be disclosed within 24 hours. CASPs must also provide ongoing market information. During trading hours, they must publish key trading data, including prices and volumes, daily highs and lows, average prices, the three best bid and offer levels, and transactions by foreign investors. By 9:00 a.m. each trading day, they must publish specified information on the previous day’s trading activity. Regulatory Reporting Requirements Separate from public disclosure, the draft requires CASPs to provide regulators with detailed information enabling ongoing supervision of their operations and the market. For market activity, CASPs must report decisions to admit or remove a crypto asset from trading within 24 hours, submit previous-day trading data to the State Securities Commission

On September 15, 2026, the Thai Food and Drug Administration (Thai FDA) opened a public consultation period on the principles of a proposed Ministry of Public Health (MOPH) notification establishing specific Good Manufacturing Practice (GMP) requirements for foods derived from cultured animal cells. The proposal would build on Thailand’s existing safety assessment framework by proposing GMP requirements specifically tailored to the production of cultivated meat. As cultivated meat advances toward commercial production, its unique manufacturing processes present food safety challenges involving aseptic conditions, starting cell quality, culture media, and specialized equipment. Thailand’s Food Act B.E. 2522 (1979) provides the legal basis for regulating food manufacturing, but no GMP requirements specifically tailored to cultivated meat have been issued under it. The proposed framework aims to address this gap. The Thai FDA has not yet released a complete draft notification, so the proposed requirements outlined below may change before adoption. However, they indicate the direction the regulator intends to take, and companies preparing to enter the Thai market can use them now to anticipate their compliance obligations. What Is Cultivated Meat? Cultivated meat, also known as cell-based food or cell-cultured meat (and referred to in the proposed notification as food derived from cultured animal cells), is produced by cultivating animal cells rather than raising and slaughtering animals through conventional meat production. The process generally begins with the selection of animal cells or stem cells, which are cultivated in an appropriate culture medium within a bioreactor to promote cell growth and proliferation. Scaffolding materials or other techniques may subsequently be used to develop cells into tissue or other forms suitable for consumption. Unlike conventional meat production, this process introduces specific food safety considerations relating to starting cells, culture media, production substances, contamination controls, and potential residues in the final product.

Vietnam is implementing and developing a broad package of regulatory reforms that could reshape how IP, data, digital platforms, and product authenticity are regulated and enforced. Several of the key measures have been led by the Ministry of Public Security in its legislative and administrative capacity, as part of a broader government effort. The core reform package consists of four key legal instruments: proposed amendments to the Criminal Code, a proposed new Data Security Law, a draft Decree on Product Identification, Authentication and Traceability, and the newly enacted Decree No. 330/2026/ND-CP. These instruments include rules on criminal enforcement, data security, electronic identification, product identification and traceability, administrative violations, and cybersecurity sanctions. Combined, these measures will affect copyright enforcement, industrial property rights, trade secrets, AI training data, product provenance, online takedowns, valuation of counterfeit goods and electronic evidence. It is worth noting that, in addition to strengthening criminal penalties for IP crimes, Vietnam’s emerging regulatory framework increasingly treats infringement, data misuse, product authentication, and platform-enabled violations as interconnected regulatory and enforcement challenges. For rights holders and foreign investors, this could mean stronger tools against counterfeiting and online infringement, but also more compliance obligations around data, traceability, AI, platform controls and government-facing reporting. Expansion of Criminal IP Enforcement Proposed amendments to Article 225 of the Criminal Code would expand criminal copyright exposure beyond reproduction and distribution to cover large-scale commercial public performance and online communication of works, phonograms and video recordings. This is important because piracy is increasingly about streaming, unauthorized communication, and platform access models rather than physical copying. Aggravated copyright infringement could be subject to up to 10 years in prison for individuals and fines of up to VND 6 billion (about USD 228,300) for commercial legal entities. The amended Article 226 would expand criminal industrial property liability beyond
