The CITT decision concluded the evidence from the investigation confirmed that between 2024 and 2025, CISP dumping imported from China and subsidisation of Chinese CISP had occurred, which was “largely responsible for the majority of injury suffered by the domestic industry.” CITT also found that the dumping and subsidization injury to Bibby was serious or “material” as noted in their report on this case. CITT also found that the injury to the domestic industry by “massive importation [is] not present in this case.” CONTRACTOR ACTION According to MPHCA president Gianna Agozzino, “We are taking the lead for the industry on this issue. Our position on this anti-dumping claim can be pared down to one issue: the market for CISP in Canada being reduced to one domestic supplier.” The association has no concern with the anti-dumping claim. However, this could mean unreasonable costs for CISP and other cast iron products, which will have a negative impact on project costs, particularly in the new home market. They are requesting a way to reconcile domestic and imported pricing within a competitive range. MPHCA wanted the final ruling to be fair, encourage competition and ensure that the federal government looks at the downstream impact on contractors and home and building owners if the number of suppliers of this pipe is significantly reduced. The government solution has resolved the anti-dumping concern, but it has not resolved MPHCA’s concern that the decision will keep the market for CISP competitive and vibrant. Since the federal government’s action is complete and the concern about competition in the CISP market is still to be resolved, MPHCA is meeting with a number of CISP suppliers to gauge their interest in entering the Canadian market. The contractor association has met with the largest manufacturer of CISP in the U.S., Charlotte Piping and Foundry, who have actually been supplying CISP in Western Canada for some time. The company has stayed out of the eastern Canadian market because of the advantage that Chinese imports have had historically. The duties that have been placed on Chinese CISP has encouraged Charlotte to consider entering the eastern Canadian market. MPHCA believes that there are probably four or five CISP manufacturers that are now looking at the Canadian market. According to Agozzino, “There are a number of other suppliers of cast iron soil pipe in the U.S. and in the far east, such as Vietnam and Thailand, that should be showing an interest in the Canadian market because of the federal duties on Chinese imports. We will continue to talk with these companies going forward. If these manufacturers enter the Canadian market, our key concern may be resolved.” THE FUTURE The final decisions on this matter have been made by the federal government and interest is being shown by a number of international CISP manufacturers. This issue seems to be coming to a reasonable conclusion for both contractors and the building industry. MPHCA will be meeting with the federal government in the coming months to reinforce their position on CISP. ◄ For more information on this issue, contact either the MPHCA president Gianna Agozzino at gagozzino@networkmech.ca or MPHCA manager Christine Kebezes at ckebezes@tcaconnect.com. association is hoping to meet with the federal government in June 2026. GOVERNMENT DECISIONS The CBSA and CITT final decisions on CISP anti-dumping were handed down on Jan. 7, 2026 (CBSA), and Feb. 6, 2026 (CITT). As noted in the CBSA decision, the product included in the ruling is CISP originating in or imported from China with tariff classification numbers normally of 7303.00.00.10 and 7303.00.00.90. Other classifications may be included that meet the government’s product definition from the Measure in Force Code (MIF Code) as follows: Cast iron soil pipe originating in or exported from the People’s Republic of China, whether finished or unfinished, regardless of industry or proprietary specifications and regardless of wall thickness, length, surface finish, end finish or stenciling, having a nominal outside diameter from 1.5 inches to 18 inches. Cast iron soil pipe is non- malleable iron pipe of various designs and sizes, including but not limited to both hubless and hub and spigot cast iron soil pipe. For greater certainty, the product definition includes all pipe meeting the physical description set forth above, whether or not produced according to a particular standard or specification. Chinese producers that cooperated with the investigation have been granted specific normal values – minimum prices for their products when selling into Canada. For these exporters, the minimum prices of duties average out to be between 184 per cent at the low end and 322.7 per cent at the high end. For all other CISP originating in or exported from China, importers face duties of 472.7 per cent. BUILDERSDIGEST Quarter 2 2026 25 CAST IRON CONCERN
