Provisional duties on cast iron soil pipe

Summary#

The Canada Border Services Agency (CBSA) made preliminary findings on October 9, 2025 that certain cast iron soil pipe imported from the People’s Republic of China has been dumped and subsidized. As a result, provisional duties are now payable on those goods while the Canadian International Trade Tribunal (CITT) conducts a full injury inquiry, which must be completed within 120 days after the Tribunal receives notice of the CBSA decisions.

What it does#

• The CBSA determined there is preliminary evidence of dumping and subsidizing of cast iron soil pipe from the People’s Republic of China.
• Provisional duties are payable on subject goods released from the CBSA starting October 9, 2025 and will apply until the earlier of:
  • the investigations are ended;
  • the CITT issues an order or finding; or
  • an undertaking is accepted.
• The provisional duties cannot exceed the estimated margin of dumping plus the estimated amount of subsidy.
• The Customs Act governs how these provisional duties must be accounted for and paid; interest rules apply if duties are not paid on time.
• The CBSA will publish a full product definition and potential tariff classification numbers on its Dumping and subsidy investigations web page.
• A Statement of Reasons for the decisions will be issued within 15 days.

Who's affected#

• Importers and customs brokers who bring cast iron soil pipe into Canada from the People’s Republic of China.
• Distributors and businesses that buy or use that specific pipe in Canada.
• Canadian firms that manufacture similar pipe — they may be involved in the CITT inquiry or affected by any final order.

Why it matters#

• Importers may face higher costs immediately because of provisional duties.
• Shipments could be delayed or held while duty accounting is sorted.
• Those who rely on this specific pipe could see changes in supply costs or sourcing options depending on the outcome of the CITT inquiry.
• The CITT’s final decision (within 120 days of its notice receipt) will determine whether duties continue, are removed, or are adjusted.
