CBSA finds dumping would continue or resume if nine-country rebar findings lapse, sending both expiry reviews to the Trade Tribunal for an injury decision due February 2027
OTTAWA, September 20, 2026
Canada’s anti-dumping duties on concrete reinforcing bar from nine countries have cleared their first survival test, and the decision moves a set of measures worth hundreds of millions of dollars in annual trade exposure into the hands of the Canadian International Trade Tribunal.
The Canada Border Services Agency completed two parallel expiry review investigations and determined, pursuant to paragraph 76.03(7)(a) of the Special Import Measures Act, that expiry of the underlying findings is likely to result in the continuation or resumption of dumping. The determinations, issued September 17 and circulated through Canadian trade compliance channels over the following days, cover rebar originating in or exported from Algeria, Egypt, Indonesia, Italy, Malaysia, Singapore and Vietnam in one file, and Oman and Russia in the other.
The agency said a Statement of Reasons containing additional detail on each determination would be issued within 15 days, placing publication at the start of October.
The two files, designated Concrete Reinforcing Bar 3 (RB3 2026 ER) and Concrete Reinforcing Bar 4 (RB4 2026 ER) on the CBSA side, correspond to Tribunal expiry reviews RR-2026-002 and RR-2026-003. Because both CBSA determinations were positive, the Tribunal now proceeds to the injury phase. It said when it initiated the reviews on April 20, 2026 that it would determine no later than February 24, 2027 whether continued or resumed dumping is likely to result in injury to the domestic industry.
For Canadian construction, that timetable matters more than the September determination itself. Rebar is not a niche import. It is the backbone commodity of concrete construction, consumed in volume by every highrise, bridge, transit tunnel, parkade, water treatment plant and industrial slab poured in the country.
What the CBSA decided
The expiry review mechanism is the least visible and most consequential part of Canada’s trade remedy system. Every SIMA finding or order lapses automatically five years after it is made. Continuation is not the default. It requires an affirmative decision on a fresh evidentiary record.
The process splits into two stages with two decision-makers. The CBSA examines whether expiry would likely lead to continued or resumed dumping, a question about exporter behaviour, global capacity, pricing in third markets and the commercial attractiveness of the Canadian market. If the answer is yes, the Tribunal then examines whether that dumping would likely injure the domestic industry.
The September 17 determinations answered the first question in the affirmative for all nine origins.
The RB3 file concerns the Tribunal’s finding of June 4, 2021 in inquiry NQ-2020-004, covering Algeria, Egypt, Indonesia, Italy, Malaysia, Singapore and Vietnam. The RB4 file concerns the finding of July 2, 2021 in inquiry NQ-2020-005, covering the Sultanate of Oman and the Russian Federation. The Tribunal initiated both expiry reviews on April 20, 2026, and the CBSA opened its corresponding investigations the following day.
The CBSA’s conclusion is unsurprising on its face. Global steel overcapacity has not eased since 2021, and several of the named origins operate export-oriented rebar capacity with limited domestic absorption. What the Statement of Reasons will show, and what parties will scrutinize in October, is the evidentiary basis: which exporters cooperated, what pricing data the agency relied on, and how it treated origins with negligible recent shipment volumes.
The rates at stake
According to trade press reporting on the expiry reviews, the anti-dumping duties currently in force on the affected origins run from 8 percent to 45 percent. SteelOrbis reported the rates as 20.3 percent for Algeria, 23.1 percent for Egypt, Italy, Malaysia, Singapore and Vietnam, 21.8 percent for Indonesia, 8 percent for Oman and 45.0 percent for Russia.
That spread is worth reading carefully. A 45 percent duty on Russian rebar is effectively prohibitive, and in any case Russian steel faces a separate and broader set of Canadian restrictions arising from sanctions measures adopted since 2022. An 8 percent duty on Omani rebar is a meaningful but not disqualifying cost, and Oman is precisely the kind of origin that can remain commercially active under a modest duty.
The cluster at 23.1 percent covering five origins reflects the way SIMA handles exporters that do not participate in an investigation. Non-cooperating exporters receive a residual rate determined on the facts available, and that rate tends to be uniform across a group. It is also the rate most likely to be contested if any of those exporters decide to participate in the Tribunal phase.
Why the domestic industry fought for continuation
Canada’s rebar producers have been among the most persistent users of the trade remedy system in the country, and the reason is structural.
Rebar is a commodity. It is manufactured to published standards, it is graded and certified, and once it meets specification one producer’s product is functionally interchangeable with another’s. Buyers purchase on delivered price. That makes the product acutely vulnerable to import pricing, because there is no brand premium, no service differentiation and no switching cost to protect a domestic mill’s position.
It is also a product whose economics turn on mill utilization. Electric arc furnace rebar operations carry substantial fixed costs and lose money quickly when volumes fall. A domestic producer facing a 10 percent volume loss cannot simply shrink to fit. It either recovers the volume or it idles capacity, and idled capacity in the steel sector has a habit of becoming permanently closed capacity.
Canada has assembled an unusually dense set of rebar measures over the past decade. The RB3 and RB4 findings covering nine origins sit alongside earlier findings covering other origins, and the whole structure now operates inside a broader steel tariff architecture that did not exist when the 2021 findings were made.
The wider steel wall
That architecture is the essential context for reading these determinations, because a rebar importer today faces considerably more than a SIMA duty.
On November 26, 2025, Ottawa announced a package of steel and lumber measures. Effective December 26, 2025, tariff rate quotas for steel products from countries without a free trade agreement with Canada were cut from 50 percent to 20 percent of 2024 volumes, and for countries with a free trade agreement in force from 100 percent to 75 percent of 2024 volumes. Over-quota volumes continue to face a 50 percent surtax. Canada preserved its carve-out for CUSMA partners. The same package applied a new 25 percent tariff to a basket of steel derivative products from all countries that Ottawa valued at roughly C$10 billion.
Global Affairs Canada subsequently extended the steel tariff rate quotas for an additional year, to June 27, 2027, and launched consultations on how the quotas should be administered.
The practical effect for rebar from a non-free-trade-agreement origin is a stacked structure. The shipment needs a shipment-specific import permit issued under item 82 of the Import Control List to enter within quota. If quota for that origin is exhausted, shipment-specific permits are no longer issued, and the goods may still enter under General Import Permit No. 80 or No. 81 while attracting the 50 percent surtax. On top of that, SIMA anti-dumping duty applies at the origin-specific rate if the goods are subject to a finding.
An importer that models only the anti-dumping duty has understated its exposure by a wide margin.
Economic impact on construction
The construction sector is the party that ultimately pays, and it is largely absent from the proceeding.
Canadian infrastructure and residential construction are both under cost pressure from multiple directions. Rebar is a material input in essentially every structural concrete application, and while it is a modest percentage of total project cost, it is a line item that moves directly with trade policy.
Three effects follow from the continuation of the rebar findings.
The first is price. Duties that remove low-priced origins from contention support domestic mill pricing. That is the intended effect and, from the perspective of Canadian steelworkers and the communities around Canadian mills, the justified one. It is also a real cost to builders, and in a housing affordability environment it is a cost that eventually reaches buyers and tenants.
The second is supply security. Concentration of rebar supply in a smaller number of domestic and preferential-origin mills raises the consequence of any single supply disruption, whether a mill outage, a labour action or a rail interruption. Large projects with fixed pour schedules have limited tolerance for delay.
The third is competitive dynamics in fabrication. Rebar is usually purchased through fabricators who cut, bend and detail the material to drawings. Fabricators with established domestic mill relationships and allocation are advantaged relative to those who built their business on imported supply. The trade measures therefore redistribute margin within the Canadian supply chain, not only between Canada and foreign mills.
Stakeholder positions
Neither the domestic producers nor the foreign exporters issued public statements in the days following the determinations, which is standard practice while a Tribunal proceeding is active.
The Tribunal described itself, in its April notice initiating the reviews, as an independent quasi-judicial body reporting to Parliament through the Minister of Finance, hearing cases on dumped and subsidized imports, safeguard complaints, federal procurement complaints and appeals of customs and excise tax rulings. It invited any interested person, association or government to participate by filing Form I, the Notice of Participation. The contact listed was Martin Pelchat, Manager, Communications and Linguistic Services.
That invitation is the operative sentence for anyone outside the steel industry who cares about the outcome.
Expiry reviews are decided on the record. Domestic producers file questionnaire responses, financial data and argument. Foreign exporters may or may not participate. Importers and downstream users can file, and in a commodity case with a large downstream constituency, their evidence is the only source of information the Tribunal has about the effect of the measures on construction cost and supply.
Historically, Canadian construction interests have not been consistent participants in steel expiry reviews. The reasons are understandable. The proceedings are technical, the cost of counsel is real, and the individual contractor’s exposure looks small relative to the effort. The aggregate effect of that non-participation is that the injury analysis is conducted largely on evidence supplied by the party seeking continuation.
What the Tribunal will weigh
The Tribunal’s task between now and February 24, 2027 is narrower than it may appear. It is not reassessing whether the 2021 findings were correct. It is asking a forward-looking question: if these duties came off, would dumping likely resume at volumes and prices likely to injure the domestic industry.
Several factors will drive that analysis.
Global rebar capacity and its direction. Overcapacity in long products has not resolved, and the export orientation of several named origins remains a central fact.
Trade diversion. This is the factor that has changed most since 2021. The United States has raised steel tariffs sharply, most recently to 50 percent on steel and aluminum and their derivatives with the tariff applied to full value rather than metal content since April 2026. Volume shut out of the American market has to go somewhere. The Tribunal has accepted diversion logic in other recent proceedings, most notably in the canned vegetables safeguard inquiry, where it found that United States trade-restrictive measures and European anti-dumping duties had pushed third-country product into Canada.
The condition of the domestic industry. Canadian rebar producers will need to show they remain vulnerable. Paradoxically, a domestic industry that has performed well under protection must argue that its performance depends on that protection continuing.
The effect of the overlapping tariff and quota measures. This is the novel question. Foreign exporters and importers may argue that the steel tariff rate quota regime and the 25 percent derivative tariff already provide the domestic industry with protection sufficient to prevent injury, making the SIMA duties redundant. The Tribunal has not previously had to weigh SIMA measures against a general steel quota regime of this scale, and how it handles the interaction could set a pattern for the many other steel expiry reviews queued behind this one.
What importers should do
The measures remain fully in force. Nothing about the September determinations changes duty liability today, and nothing will change it before the Tribunal rules.
Several steps are nonetheless time-sensitive.
Read the Statement of Reasons when it publishes at the start of October. It will disclose the CBSA’s reasoning, the cooperation record and the data relied on. For any importer considering participation, that document defines the terrain.
Decide on participation promptly. Form I filings and the Tribunal’s schedule for RR-2026-002 and RR-2026-003 will govern. An importer or construction association that wants its cost and supply evidence in the record must file early.
Verify origin rigorously. With nine origins subject and rates ranging from 8 to 45 percent, origin documentation is the single highest-risk compliance area. Transshipment through a non-subject country does not change origin, and the CBSA has become notably more active on origin verification across steel files.
Model the full stack. Anti-dumping duty, tariff rate quota status, the over-quota 50 percent surtax, and where applicable the 25 percent steel derivative tariff, are four separate exposures. Quotas are administered on a first-come, first-served basis and can exhaust, at which point goods enter under a general import permit and pay the surtax.
Review contract terms. Long-lead construction supply agreements written on the assumption that duties would lapse in 2026 now need revisiting. The measures will remain in force at least until the Tribunal rules in February 2027, and if the Tribunal continues them, for a further five years.
How Canada came to have this many rebar measures
The density of Canadian rebar trade remedies is itself worth explaining, because it is unusual by international standards and it shapes how the current reviews will be argued.
Canada opened its modern rebar enforcement era in the mid-2010s, when a first round of complaints produced findings against a group of Asian and European origins. What followed is a pattern familiar in commodity steel enforcement everywhere: measures against one set of origins are followed within a few years by a surge from a different set, and a new complaint follows.
The 2021 findings in NQ-2020-004 and NQ-2020-005 are the third and fourth generation of that sequence. Their origin lists tell the story. Algeria, Egypt, Indonesia, Italy, Malaysia, Singapore, Vietnam, Oman and Russia are not the countries a Canadian buyer would have named as major rebar sources a decade earlier. They became major sources precisely because earlier measures removed the prior ones from contention.
This is the core policy dilemma of commodity trade remedy. Each individual case can be entirely well founded on its evidence, and the cumulative effect can still be a treadmill in which the domestic industry files serially against successive origins while the underlying condition, global overcapacity in a standardized product, never changes.
Ottawa’s response since late 2025 has been to shift part of the burden from case-by-case enforcement to a general quota regime that operates regardless of origin behaviour. Whether that shift reduces the need for SIMA cases, or simply adds a layer on top of them, is an open question that the current rebar reviews will begin to answer.
The diversion argument in detail
Trade diversion is likely to be the central factual battleground in the Tribunal phase, and the record elsewhere in the Canadian system is now unusually rich on the point.
The mechanism is simple. When a large importing market raises barriers, the volume it previously absorbed does not stop being produced. It seeks the next most attractive market, and attractiveness is a function of market size, price level, tariff barriers and the ease of entry.
Canada scores poorly on the first factor and, until recently, well on the others. It is a relatively high-price market adjacent to the largest steel-consuming economy in the world, with a historically open trade regime and efficient port and rail access. For an exporter shut out of the United States, Canada has been the obvious second choice.
The United States raised steel and aluminum tariffs to 50 per cent in June 2025, and in April 2026 extended the tariffs to apply to the full value of steel, aluminum and copper articles and their derivatives rather than only to metal content, with rates ranging from 10 to 50 per cent. Those are very large barriers, and they apply globally.
The Tribunal has already accepted diversion reasoning in a different sector this year. In the canned vegetables safeguard inquiry, it found that United States trade-restrictive measures and European anti-dumping duties on Chinese sweetcorn were unforeseen developments that diverted third-country product into Canada, and that the resulting import surge was the principal cause of serious injury to Canadian producers.
Whether the same logic carries in rebar depends on the evidence about each named origin’s capacity, its export orientation and its historical behaviour toward the Canadian market. Origins with negligible recent shipments will argue that diversion is speculative in their case. Origins with demonstrated capacity and a record of shipping to Canada before the findings will find that argument harder to make.
A note on Russia
The Russian component of the RB4 file sits in a category of its own and should not be read as an ordinary commercial case.
The existing anti-dumping duty on Russian rebar is reported at 45.0 per cent, by a wide margin the highest rate in either file. Beyond SIMA, Russian-origin goods have faced a far broader set of Canadian restrictions since 2022, including measures that effectively foreclose most commercial steel trade.
The practical consequence is that continuation or expiry of the SIMA finding on Russian rebar is unlikely to change trade flows materially in the near term. It matters as a legal matter, because a lapsed finding is difficult to reinstate quickly, and because the domestic industry has an interest in keeping every origin on the list against a future in which the broader restrictions change.
Oman presents the opposite profile. At 8 per cent, the duty is low enough that Omani rebar could plausibly re-enter the Canadian market in volume, particularly if the exporter is able to demonstrate normal-value pricing. Of the nine origins, Oman is among the more likely to warrant close attention in the injury analysis.
The pattern in Ottawa
The rebar determinations landed in a week of unusually heavy Canadian trade remedy activity. The CBSA made a preliminary determination of dumping on wheat gluten from Italy, Poland and the United Kingdom, with provisional duties payable from September 17. It published its reasons for provisional dumping and subsidy duties on steel racks from China. The Tribunal opened a final injury inquiry into wheat gluten and, separately, rescinded an eleven-year-old order on Chinese photovoltaic modules and laminates.
Read together, those decisions describe a system enforcing vigorously where a domestic industry can prove a case and releasing measures where it cannot. Rebar sits firmly in the first category. Canadian long steel producers have the production base, the data and the institutional experience to sustain an injury argument, and they have done so repeatedly.
The question the Tribunal will answer by February is whether the case still holds in a market where Canada has already built a second and third wall around the same product.
