On November 17, 2025, Thailand’s Ministry of Interior introduced significant regulatory changes to make rooftop solar adoption easier and more cost-effective for property owners. Ministerial Regulation No. 72 B.E. 2568 (2025), issued under the Building Control Act B.E. 2522 (1979), was published in the Government Gazette on November 19, 2025, with immediate effect. Background Under the Building Control Act (BCA), any alteration made to a building requires either notification of the relevant authority or application for a building alteration permit—unless the alteration falls under a separate list of exceptions specified in the ministerial regulations issued under the BCA. In 2015, installation of solar rooftops on any residential building under 160 square meters was added to this list of exceptions, subject to inspection and notification requirements. The newly enacted regulation now eliminates many of these requirements and introduces a broader and more permissive framework to promote solar adoption nationwide. Key Changes Specifically, the regulation introduces three major changes: Expanded exemption from the definition of “building alteration”: The installation of solar panels on any building roof—regardless of the type of building or the total area of the installation—is no longer considered a building alteration under the BCA, provided that the total weight of the installation does not exceed 20 kg/m2. Removal of structural integrity certification requirement: The new regulation eliminates the obligation to obtain a structural stability certificate from a licensed civil engineer. Removal of notification requirement: Property owners or possessors are no longer required to notify the local authority before installation of a solar rooftop. Impact This significant streamlining of requirements for solar rooftop installation is expected to accelerate the adoption of renewable energy in the country, particularly for residential and commercial properties—similar to the way Thailand’s December 2024 removal of licensing requirements for factory solar rooftop installations encouraged such

Thailand’s Customs Department has announced the cancellation of the longstanding de minimis exemption, which waives import duties on goods valued at THB 1,500 or less, as of January 1, 2026. This policy shift will directly impact e-commerce, logistics, and retail sectors, and will have wide-ranging implications for any company involved in cross-border trade with Thailand. Background Under current regulations, imported goods with a customs value (cost, insurance, and freight, or “CIF”) of THB 1,500 or less are exempt from import duties. This has been a cornerstone of the cross-border e-commerce model, allowing for the duty-free import of millions of small parcels. Under the new policy effective January 1, 2026, all imported goods, regardless of value, will be subject to assessment for import duties upon entry into Thailand. The stated rationale for this change is to create fair competition for Thai small and medium-sized enterprises (SMEs), which must pay VAT and other costs on their goods, putting them at a price disadvantage against foreign sellers who utilize the de minimis loophole. Business Implications This policy change will create new costs, compliance burdens, and operational challenges. For foreign e-commerce sellers and platforms: The most direct impact will be the addition of import duties to low-value items. Assuming the costs are passed on to the consumer, the higher prices and potentially more complex or slower customs clearance processes could lead to increased cart abandonment and reduced consumer demand. Businesses should review their pricing models and develop a clear strategy for calculating, declaring, and paying these new duties. For logistics providers and customs brokers: The administrative burden will be considerable. Carriers that previously handled millions of nondutiable parcels will now be required to process them for duty assessment and collection. This may necessitate new IT systems and streamlined processes to avoid delays at
