Türkiye Opens Anti-Dumping Investigation into Chinese Aluminium Frames for Photovoltaic Panels (Tebliğ 2025/10)

Mechanism

Tebliğ No. 2025/10 (İthalatta Haksız Rekabetin Önlenmesine İlişkin Tebliğ), published in Resmî Gazete No. 32910 on 25 May 2025, opened a standard Turkish anti-dumping investigation under the Regulation on the Prevention of Unfair Competition in Imports. The petition came from three domestic aluminium-frame producers — Arslan Aluminium, Lazer Solar Energy Aluminium Systems, and Pantech Aluminium — represented by the Turkey Aluminium Manufacturers Association (TALSAD). The investigated product is aluminium frames used to mount photovoltaic panels (GTIP/HS 8541.90.00.00.11), sourced from China. The export-pricing review period ran October 2023– September 2024; the injury-assessment period ran January 2022–September 2024.

On 13 December 2025 the Ministry published Tebliğ No. 2025/41 (Resmî Gazete No. 33106), imposing provisional duties on a CIF basis: Jiangsu Yuejia Metallic Technology 14.79%; Jiangyin Haihong New Energy Technology 27.20%; Anhui Krant Aluminum Products, Jiangyin Yuanshuo Metal Technology, Yangzhou Yu Xin Metal Products, and Zhejiang Twinsel Electronic Technology each 21.99%; all other Chinese exporters 31.40%. Provisional measures were capped at six months pending the final determination.

The investigation concluded with definitive duties (Tebliğ 2026/23, 24 June 2026 — see amendments) that roughly doubled the named-company rate to 38.26% and set the residual "all others" rate at 45.99%, in force for five years.

Downstream implications

• Turkish PV-module assemblers relying on Chinese-sourced aluminium framing

face a material CIF cost increase (14.79–31.40% during the provisional window, 38.26–45.99% under the definitive measure), pushing sourcing toward domestic frame producers (Arslan, Lazer Solar, Pantech) or non-Chinese suppliers.

• Extends Türkiye's growing anti-dumping architecture against Chinese

solar-supply-chain inputs, alongside the 2023-07-17 photovoltaic-cell import-surveillance-value increase and the 2026-05-24 aluminium-foil sunset-review extension (Tebliğ 2026/16) — a layered defensive-tariff stack across upstream aluminium products.

• Six named Chinese exporters retain a materially lower duty than

non-cooperating "all other" producers, creating an incentive for unnamed/new Chinese exporters to seek individual rate reviews.

Open questions

• Whether Chinese exporters will route aluminium-frame shipments through

third countries to avoid the definitive duty (a pattern seen in EU/US solar-supply-chain AD cases).

• Whether the definitive duty triggers a broader EU or US parallel

investigation given shared exposure to Chinese PV-aluminium overcapacity.
