RENEWED DUMPING DUTIES ON WINDOW WALLS

CITT CONCLUDES EXPIRY REVIEW ON CHINESE "UNITIZED WALL MODULES"

On March 19, 2025, the Canadian International Trade Tribunal (the “CITT”) announced an Order in Expiry Review RR-2024-001 (the “Order”), continuing its finding of material injury in respect of the dumping of Unitized Wall Modules originating in or exported from the People’s Republic of China (the “Subject Goods”). These goods are used in “curtainwall” or “window wall” systems for the exterior of multi-story buildings.

The Subject Goods

The Subject Goods are defined as:

Unitized wall modules, with or without infill, including fully assembled frames, with or without fasteners, trims, cover caps, window operators, gaskets, load transfer bars, sunshades and anchor assemblies; excluding non-unitized building envelope systems such as stick systems and point-fixing systems originating in/or exported from the People's Republic of China.

On November 25, 2024, the Canadian International Trade Tribunal (the “CITT”) issued a notice that it was beginning an expiry review in respect of certain Aluminum Extrusions originating in or exported from the People’s Republic of China (the “Subject Goods”).  On November 26, 2024, the Canada Border Services Agency (the “CBSA”) similarly gave notice of the initiation of their parallel expiry review investigation.

More details on the technical definition of the Subject Goods can be found here.

On October 1, 2024, the Canadian government released the final list of which goods will be subject to the 25% surtax on steel and aluminium products coming from the People’s Republic of China effective October 22, 2024 (the “Final List”).  

The Final List is rather broad, and includes many items of iron, steel, or aluminum that could be used by manufacturers across various industries, including ingots, flat-rolled coils, bars and rods, extrusion shapes and sections, tubes pipes and hollow profiles, etc.
