Cambodia’s New Sub-Decree No. 52 Set to Boost Solar Energy Adoption
Cambodia is taking a significant step towards a greener future with the introduction of Sub-Decree No. 52. Issued on March 26, 2026, and effective from April 1, 2026, this new regulation is poised to accelerate the country’s transition to clean energy by making solar power technology more accessible and affordable.
The sub-decree underscores a clear and continued policy commitment from the Royal Government of Cambodia to champion clean energy adoption, alongside the growth of electric mobility and downstream manufacturing sectors.
Key Tariff Adjustments under the Cambodia solar energy decree
At the heart of Sub-Decree No. 52 is the strategic elimination of customs import duties on a range of critical components for the renewable energy and electric vehicle (EV) industries. For the solar sector, this is a game-changing development.
Previously, key solar components were subject to import duties ranging from 7% to 15%. Under the new regulation, these tariffs have been reduced to 0%. The key items benefiting from this change include:

- Solar Batteries and Lithium Batteries: Duty reduced from 15% to 0%.
- Complete Solar Systems: Duty reduced from 15% to 0%.
This decisive fiscal measure also extends to the burgeoning electric mobility market, dropping duties on EV batteries, powertrain components, chargers, and cables to zero. This holistic approach signals a coordinated strategy to build a comprehensive clean energy ecosystem.
Implications for the Market and Consumers
The immediate effect of this sub-decree will be a reduction in the landed costs for importers and distributors of solar energy products. This cost saving is expected to be passed down through the supply chain, making solar installations more economically viable for both residential and commercial users.
By lowering the financial barrier to entry, Sub-Decree No. 52 is set to enhance the competitiveness of solar-related household appliances and large-scale systems, driving wider adoption across the nation. This move not only supports Cambodia’s environmental goals but also provides a significant boost to businesses operating in the renewable energy space.
For businesses looking to capitalize on these new incentives, it is crucial to ensure compliance. Companies should verify the Harmonized System (HS) classifications for their imported goods and prepare all necessary documentation to be eligible for the 0% duty rate.
As detailed by legal and tax advisory firm DFDL, this sub-decree is a clear reflection of Cambodia’s forward-thinking policy on sustainable development. You can find more information on the specific adjustments here.
In conclusion, Sub-Decree No. 52 is more than just a fiscal adjustment; it is a powerful catalyst for Cambodia’s solar energy revolution. By making clean technology more affordable, the government is paving the way for a more sustainable and energy-independent future.
