March 15, 2026 – CST ENERGY, a leading provider of home energy storage solutions and high-performance lithium iron phosphate (LiFePO4) battery systems with a focus on the Southeast Asian market, today details its proactive strategies to adapt to the 2026 global lithium battery export policy changes. These changes include China’s adjusted export tax rebate policy and updated localized regulations across Southeast Asia. As a trusted partner for distributors, installers, and residential customers throughout the region—primarily the Philippines, Vietnam, and Thailand—CST ENERGY is dedicated to mitigating policy impacts, ensuring stable product supply, and delivering sustainable value for partners amid the evolving industry landscape.
2026 is a pivotal year for the global lithium energy storage export market, shaped by two core policy shifts: China’s phased reduction of battery export tax rebates and the gradual upgrading of localized policies in Southeast Asian nations. While these changes present challenges, they also create opportunities for high-quality market players. CST ENERGY has tailored its strategies to align with these policy trends, strengthen its market position, and support the long-term growth of its partners across the region.
Core 2026 Export Policy Changes & Regional Impact
The 2026 export policy adjustments—led by China’s tax rebate revisions and Southeast Asia’s localized regulatory updates—directly impact the cost structure, market access, and development direction of the energy storage industry in key markets including the Philippines, Vietnam, and Thailand:
1. China’s Export Tax Rebate Adjustment: Phased Reduction to Drive Industry Upgrade
Issued by China’s Ministry of Finance and State Taxation Administration (Announcement No. 4 of 2026), the export tax rebate policy for battery products has been adjusted in two clear phases:
• April 1 to December 31, 2026: The VAT export tax rebate rate for battery products—including lithium-ion batteries, lithium iron phosphate batteries, and all energy storage battery categories—will be reduced from 9% to 6%.
• January 1, 2027 onwards: The export tax rebate for all battery products will be completely abolished.
For CST ENERGY, which focuses on exporting to Southeast Asia, this adjustment translates to a short-term cost increase of approximately 3%. However, it also accelerates the elimination of low-quality, low-cost产能 in the industry—creating a more standardized, reliable market environment that benefits high-quality manufacturers like CST ENERGY and its partners.
2. Localized Policies in Southeast Asia: Compliance Requirements & Market Opportunities
Key Southeast Asian markets—the Philippines, Vietnam, and Thailand—have introduced targeted policies that set compliance standards while unlocking significant market opportunities for energy storage enterprises:
• Philippines: Long-term preferential policies include zero import tariffs on energy storage equipment, a 10-year corporate income tax exemption for new energy projects, and a mandatory 20% energy storage requirement for renewable energy projects above 10MW (implemented since February 2026). These policies effectively offset the impact of China’s tax rebate reduction, generating a stable annual demand of approximately 5GWh. Additionally, the Philippines’ customs system requires complete declaration and inspection documents, and CST ENERGY has established a dedicated customs clearance team to ensure seamless, hassle-free market access for its partners.
• Vietnam: Energy storage products are subject to a 5% basic import tariff plus 10% VAT, with RCEP most-favored-nation treatment available. Since 2026, new centralized photovoltaic power plants have been required to equip ≥15% energy storage capacity with a discharge duration of no less than 4 hours. Localization requirements have also been introduced: 20% of key components must be locally produced in 2026, rising to 50% by 2028. Vietnam aims to reach 200MW of battery energy storage installed capacity by 2030, opening up broad market space for high-quality energy storage solutions.
• Thailand: Battery products face a 10% import tariff plus 7% VAT, with mandatory TISI certification (TIS 62133-2:2565) for energy storage batteries implemented in 2026. Since January 2026, electric vehicles must use locally produced batteries, and photovoltaic projects are required to equip ≥15% energy storage systems. While Thailand’s strict product certification and localization requirements pose compliance challenges, the country’s booming middle class and 3.8 trillion baht green energy investment plan also offer substantial market potential for trusted partners.
CST ENERGY’s Strategic Response: Compliance, Localization & Partner Empowerment
To address the 2026 export policy changes, CST ENERGY has developed a three-pronged strategy focused on compliance, localization, and partner support. This approach ensures business stability and sustained value for partners amid policy adjustments, aligning with the company’s long-term commitment to the Southeast Asian market and its mission to empower households and businesses with reliable, sustainable energy solutions.
1. Proactive Compliance: Seamless Market Access & Quality Assurance
CST ENERGY has fully aligned its production, supply chain, and quality control systems with both China’s export policies and Southeast Asia’s localized regulatory requirements, ensuring partners can access markets without barriers:
• Compliance with China’s Tax Rebate Policy: The company has optimized production efficiency and supply chain management, reducing production costs by 1-2% to offset the impact of the tax rebate reduction. It also guides partners to reasonably arrange order declaration timelines, helping them lock in the 9% tax rebate before April 1, 2026.
• Localized Certification & Customs Clearance: CST ENERGY has proactively completed Thailand’s TISI certification, with a professional team dedicated to certification updates and maintenance. For the Philippines, the company prepares all required customs clearance documents—including non-waste certificates and UN38.3 test reports—to ensure smooth clearance. For Vietnam, it provides RCEP certificates of origin, helping partners secure preferential tariff treatment.
• Alignment with China’s Battery Recycling Regulation: Building on its compliance with China’s landmark battery recycling regulation (effective April 1, 2026), CST ENERGY integrates all its LiFePO4 battery systems into the national traceability platform. Each battery pack is assigned a unique digital ID for full lifecycle traceability, further enhancing product competitiveness in Southeast Asian markets.
2. Localization Layout: Reducing Costs & Enhancing Service Efficiency
Drawing on industry best practices in overseas localization, CST ENERGY is accelerating its localized footprint in Southeast Asia to adapt to regional policy trends and deliver faster, more responsive support to partners:
• Philippines: Planning a joint-venture 2-5GWh battery Pack factory to leverage the country’s 10-year corporate income tax exemption, covering the Philippine market and radiating to surrounding Southeast Asian nations.
• Vietnam: Launching an SKD assembly plant in 2026 to meet the country’s localization requirements, reduce import costs, and shorten delivery cycles. The plant will focus on the commercial and industrial energy storage market, offering 500kWh standard modular products tailored to local needs.
• Thailand: Partnering with local leading energy enterprises (such as PTT and Banpu) to establish a joint-venture battery and system factory. This collaboration leverages local resources to avoid localization barriers and access government subsidies, ensuring long-term market competitiveness.
• Regional Service Network: Establishing regional service centers in Manila, Ho Chi Minh City, and Bangkok to provide 24-hour after-sales maintenance, technical support, and battery health monitoring services—strengthening trust and stickiness with partners and end-users.
