Investigation into Chinese unarmoured building cables

Summary#

The Canada Border Services Agency has opened an investigation under the Special Import Measures Act (SIMA) into alleged injurious dumping and subsidizing of unarmoured building cables from the People’s Republic of China. The decision was made on March 16, 2026, and the agency says a Statement of Reasons will be available within 15 days.

What it does#

• Starts a formal probe to see whether imports of unarmoured building cables from the People’s Republic of China are being dumped or subsidized and whether that is harming Canadian industry.
• Directs readers to the CBSA Dumping and subsidy investigations webpage for the full product definition and the applicable tariff classification numbers.
• Notes that a Statement of Reasons explaining the decision will be published within 15 days of the decision.

Who's affected#

• Canadian producers of building cables or makers of similar electrical distribution cable.
• Importers, distributors and wholesalers who bring unarmoured building cables into Canada.
• Businesses that buy these cables, such as electrical contractors, builders and distributors, may notice changes in supply or prices if measures follow.
• Exporters and manufacturers in the People’s Republic of China that supply these products.

Why it matters#

• If the investigation finds dumping or subsidizing and that Canadian producers are harmed, it could lead to anti-dumping or countervailing duties on those imports. That can raise import costs and change where buyers source cables.
• The probe signals concern about competition and supply in the market for these cables. More concrete effects will depend on the outcome of the investigation and any measures the CBSA imposes.
