Turkey’s Ministry of Trade has introduced two important anti-dumping measures affecting the photovoltaic (PV) solar industry. The decisions are aimed at protecting domestic manufacturers from imports that are believed to be sold at unfairly low prices. The actions focus on solar glass and aluminum frames, two key components used in the production of solar panels.
The first measure is a new anti-dumping investigation into solar glass imports from China, Malaysia, and Vietnam. The investigation officially began on June 19, 2026, following the publication of Official Notice 2026/10. It was launched after requests from Turkish manufacturers who claimed that imported solar glass was harming local producers.
As part of the investigation, the Ministry of Trade will examine whether dumping took place between October 2024 and September 2025. It will also assess the impact of these imports on the domestic industry by reviewing economic data from January 2022 onward. The investigation became effective immediately after the official notice was published.
The Turkish government has also provided an opportunity for all interested parties to participate in the investigation. Foreign exporters, importers, domestic buyers, and other stakeholders have been given 37 days from the publication date to complete questionnaires and submit their comments, evidence, and arguments before the ministry reaches its final decision.
In a separate development, Turkey has completed its anti-dumping investigation into aluminum frames used in solar panels. On June 24, 2026, the Ministry of Trade issued Official Notice 2026/23, concluding that photovoltaic aluminum frames imported from China had been dumped into the Turkish market.
Following the findings, the government has imposed definitive anti-dumping duties on these imports. The duties will be calculated on a cost, insurance, and freight (CIF) basis and will remain in force for five years.
The investigation into aluminum frames began in May 2025. During the process, Turkish authorities examined import data covering late 2023 to late 2024 and assessed the impact on local manufacturers using economic data from 2022 onward. In December 2025, the ministry introduced provisional anti-dumping duties ranging from 14.79% to 31.40% while the investigation continued.
With the final ruling now issued, those temporary duties have been replaced by permanent tariffs that will remain effective for the next five years. Together, the new solar glass investigation and the final aluminum frame ruling reflect Turkey’s continued efforts to strengthen its domestic solar manufacturing industry, ensure fair trade practices, and reduce the impact of low-priced imports on local producers.
