The Canada Border Services Agency (CBSA) initiated investigations on July 11, 2025, under the Special Import Measures Act, respecting the alleged injurious dumping and subsidizing of cast iron soil pipe originating in or exported from the People’s Republic of China.

These tariff classification numbers may include non-subject goods, and subject goods may also fall under additional tariff classification numbers.
The product definition is contained in Appendix 1.
The CBSA will investigate whether the imports are being dumped and/or subsidized; and will make a preliminary decision within 90 days, at which time provisional duties may apply.
Additional information about the investigations will be provided in a Statement of Reasons that will be accessible within 15 days.
