Investigation: Unarmoured Building Cables from China

Summary#

On March 16, 2026, the Canada Border Services Agency opened formal investigations under the Special Import Measures Act into alleged injurious dumping and subsidizing of unarmoured building cables from the People’s Republic of China. The CBSA says a Statement of Reasons will be made available within 15 days after the decision.

What it does#

• Starts anti‑dumping and countervailing-style investigations into imports of unarmoured building cables from the People’s Republic of China.
• Points people to the full product definition and applicable tariff classification numbers on the CBSA Dumping and subsidy investigations webpage.
• Commits to publishing a Statement of Reasons within 15 days following the decision to initiate the investigation.

Who's affected#

• Canadian companies that make or sell building cables and related conductors are the most directly affected.
• Importers and exporters of these cables — especially those trading with the People’s Republic of China — will also be involved.
• Others in the electrical and construction supply chain (distributors, contractors, large buyers) may notice effects.
• The notice does not list specific companies or give detailed tariff numbers in this announcement.

Why it matters#

• These investigations are the first step in a process that can result in duties or other trade remedies if dumping/subsidizing and injury to Canadian producers are found.
• That outcome could raise the cost or change the availability of the affected cables for builders, renovators, and businesses that buy them.
• The CBSA webpage has the technical product definition and tariff details people would need to check if they think they are affected.
