Canadian Trade Tribunal Launches Interim Review of Solar Module Trade Measures on China

The Canadian International Trade Tribunal (CITT) has initiated an interim review of its existing order concerning the dumping and subsidization of solar modules and laminates originating in or exported from China.

The review relates to Order RR-2020-001, issued on March 25, 2021, which covers solar modules and laminates made with crystalline silicon cells, as well as thin-film photovoltaic products based on amorphous silicon, cadmium telluride (CdTe), and copper indium gallium selenide (CIGS).

Under the original order, certain products are excluded, including modules, laminates, and thin-film products with a power output of 100 W or less, as well as products integrated into electrical appliances whose primary function is not electricity generation.

In a statement posted by the tribunal, the CITT said the purpose of the interim review is to determine whether the order should be continued, amended, or otherwise adjusted.

According to the notice of commencement, Kings Solar Solutions submitted a request on August 25, 2025, seeking an exclusion for flexible solar panels designed to be affixed to curved surfaces. Following this request, on October 15, 2025, Heliene Inc. and Silfab Solar Inc. indicated their willingness to support an exclusion for low-wattage solar modules, including those with a rated output not exceeding 200 W.

After examining the submissions, the tribunal concluded that an interim review is warranted but said the scope of the review will be limited to the exclusion request submitted by Kings Solar Solutions Inc.

The CITT has invited interested parties, including governments, to participate in the interim review by filing a notice of participation no later than December 23, 2025. The tribunal stated that a decision will be issued “in due course.”
