While the trade war with Washington dominates headlines, Canada has quietly opened a second front, imposing provisional anti-dumping and countervailing duties of up to 227.5 percent on decorative plywood from China and testing the durability of this year’s hard-won thaw with Beijing.
OTTAWA, August 28, 2026
Canadian importers of Chinese plywood woke up this week to a dramatically different cost structure. The Canada Border Services Agency has begun collecting provisional duties on certain decorative and other non-structural plywood originating in or exported from China, with rates ranging from zero to 173.6 percent for eleven named exporters and a punishing 227.5 percent of export price for everyone else. The provisional measures, which apply to subject goods released from customs beginning August 24, follow the agency’s preliminary determinations that the plywood has been dumped into the Canadian market and subsidized by the Chinese state.
The new measure, designated DONP2 under Canada’s Special Import Measures Act, or SIMA, is among the most aggressive trade remedy actions Canada has taken against Chinese goods in recent years, and it arrives at a delicate moment. Barely seven months ago, Ottawa and Beijing struck a series of agreements that unwound the most damaging tariffs in their own bilateral trade war. The plywood duties are a reminder that even as governments negotiate truces at the political level, Canada’s quasi-judicial trade remedy system grinds on, case by case, with consequences that can reach hundreds of percent of a product’s value.
What the CBSA decided
The investigation began on April 10, 2026, when the CBSA initiated parallel dumping and subsidy probes into decorative and other non-structural plywood from China, typically following a complaint from Canadian producers. On August 24, the agency issued preliminary determinations in both investigations, concluding that there was evidence the goods were being sold into Canada at less than normal value and benefiting from countervailable subsidies.
Those preliminary findings trigger provisional duties, payable immediately on subject goods released from the CBSA on or after August 24. The agency assigned exporter-specific provisional rates to eleven Chinese companies it investigated. At the favourable end, Pizhou Jiangshan Wood Co., Ltd. received a rate of zero, and Shandong Hengjia New Material Co., Ltd. a rate of 6.1 percent. In the middle of the range sit exporters such as Linyi Jiahe Wood Industry Co., Ltd. at 8.4 percent, Xuzhou Meibang Wood Co., Ltd. at 12.6 percent, Pingyi Fuwanjia Wooden Products Factory at 13.9 percent, Suzhou Dongsheng Wood Co., Ltd. at 24.7 percent, Linyi Evergreen Wood Co., Ltd. at 38.4 percent, and Dehua TB New Decoration Material Co., Ltd. at 43.3 percent. At the punitive end, LinYi QianFeng Wood Factory faces 82.8 percent, Feixian Jianhao Wood Factory 172.1 percent, and Shandong Baozhu International Trading Co., Ltd. 173.6 percent.
Any Chinese exporter not among the eleven, which in practice covers a large share of the trade, faces the all-others rate of 227.5 percent of export price. At that level, the duty is not a cost to be managed but a prohibition in all but name.
The provisional period will end at the earlier of several milestones: termination of the investigations, a finding by the Canadian International Trade Tribunal, or acceptance of an undertaking from exporters. Under the published schedule, the CBSA will issue final determinations by November 23, 2026, and the tribunal is due to rule on injury to Canadian producers by December 22, 2026. If the tribunal finds injury, definitive duties would follow, typically for at least five years, subject to expiry reviews.
A precise, and complicated, product definition
As with most trade remedy cases, the commercial impact turns on a product definition of considerable technical precision. The measure covers decorative and other non-structural plywood, whether or not surface coated or covered, as well as veneer core platforms used to produce such plywood, originating in or exported from China. Covered products are flat, multilayered plywood or other veneered panels consisting of two or more layers or plies of wood veneers and a core, with a wooden face or back veneer, bonded together. Products meeting the ANSI/HPVA HP-1-2016 hardwood plywood standard are explicitly included.
The exclusions matter just as much. Structural plywood manufactured to US Product Standards PS 1-09, PS 2-09 or PS 2-10, or substantially equivalent international standards, with coniferous face and back veneers, is outside the measure. So are finished plywood products for flooring, plywood in shapes other than flat panels, certain phenolic film faced plyform used in concrete forming, and specified laminated veneer lumber door and window components meeting CBSA requirements.
The CBSA lists fifteen tariff classification numbers under heading 44.12 as those usually used to import the subject goods, but the agency stresses that classification does not determine coverage. Goods entering under listed codes may fall outside the measure, and subject goods may arrive under codes not listed. It is the product definition, not the customs classification, that controls, which means importers cannot rely on their HS codes alone to conclude they are safe.
The burden lands on importers first
Anti-dumping duties are assessed against exporters’ pricing behaviour, but they are paid by importers, and the compliance obligations that took effect this week are significant. Importers of potentially affected plywood must review any goods released on or after August 24, verify the exporter and its assigned rate, and confirm whether their products meet the definition or qualify for an exclusion.
Canada’s CARM system, the CBSA’s assessment and revenue management platform, will generally calculate SIMA duties based on the information importers provide, and importers are responsible for verifying those assessments and self-declaring corrections. Requests for re-determination must be filed through the CARM Client Portal. The documentation requirements are extensive: import paperwork must identify the producer and its plant location, the exporter and vendor, the species and grade of face and back plies, core type, coatings, dimensions, pricing, terms of sale and more. Failure to provide required information can attract penalties under the Administrative Monetary Penalty System.
For Canada’s building products and furniture supply chains, the practical question is where replacement volume will come from. Decorative plywood from China feeds cabinet makers, furniture manufacturers, retailers and distributors across the country. Domestic producers, whose complaint prompted the investigations, argue that fairly traded Canadian panels can fill the gap, and that the duties simply restore a level playing field distorted by dumped and subsidized imports. Importers counter that domestic capacity in decorative grades is limited and that the all-others rate will function as an embargo, raising costs for downstream manufacturers already coping with a weak construction market and the parallel disruptions of the US trade war.
Both arguments will get their formal hearing at the Canadian International Trade Tribunal, whose injury inquiry will decide whether the duties become definitive in December. Tribunal proceedings give importers, purchasers and exporters the opportunity to contest injury, seek product exclusions, and argue over the scope of the measure.
Echoes of the American precedent
Canada’s action does not occur in a vacuum. The United States has maintained anti-dumping and countervailing duty orders on hardwood plywood from China since 2018, with combined rates that frequently exceed 200 percent, and American authorities have spent years pursuing circumvention cases against transshipment of Chinese plywood through third countries. Trade watchers have long noted that when one North American jurisdiction erects a trade remedy wall, diverted volume tends to flow toward the other, and Canadian producers have argued that exactly this diversion intensified pressure on their market.
The Canadian duties, if confirmed, would substantially harmonize the North American treatment of Chinese decorative plywood, closing what remained of the price gap between the two markets. That alignment carries a certain irony in the current moment: Canada and the United States are otherwise locked in their own escalating tariff conflict, with Washington’s 50 percent Section 338 tariffs on Canadian goods in force since August 22 and Ottawa’s counter-tariffs on more than 700 American products taking effect September 8. Even as the two neighbours tax each other’s steel, dairy and appliances, their trade remedy systems are converging on the same posture toward Chinese plywood.
A test of the Canada-China thaw
The more consequential diplomatic backdrop is the fragile normalization between Ottawa and Beijing. The two countries spent 2024 and 2025 in an intensifying trade war of their own, triggered by Canada’s 100 percent surtax on Chinese electric vehicles and answered by Chinese anti-discrimination duties on Canadian canola, seafood and pork that devastated prairie exporters.
That conflict began to unwind this year. In January, Prime Minister Mark Carney visited Beijing and reached agreements with Chinese President Xi Jinping under which Canada would admit up to 49,000 Chinese electric vehicles annually at a 6.1 percent tariff in exchange for relief on agricultural products, according to Al Jazeera. By March, China had slashed its countervailing duty on Canadian canola seed from a preliminary 75.8 percent to 5.9 percent, bringing the effective rate to roughly 14.9 percent including the standard import levy, and committed to exempting canola meal, lobster, crab and peas from its anti-discrimination tariffs, according to reporting by RealAgriculture and BNN Bloomberg.
A trade remedy case against a significant Chinese export sector inevitably tests that detente. Beijing has historically treated SIMA and similar proceedings as irritants rather than casus belli, and Canada’s plywood duties are narrower and more technical than the sweeping EV surtax that ignited the earlier conflict. Chinese authorities have not, as of this week, announced any retaliatory response. But with Canadian canola only months into its recovered access to the Chinese market, exporters in Western Canada will be watching nervously for any sign that Beijing views the plywood case as a breach of the spirit of the January agreements.
Canadian officials, for their part, emphasize that SIMA proceedings are law-driven and initiated by domestic industry complaints, not by political direction. That is true, and it is also true that Canada’s broader trade strategy is being rewritten in real time. With the United States imposing 50 percent tariffs on Canadian goods and Canada retaliating in kind, Ottawa needs functional trading relationships with Asia and Europe more than at any point in decades. Managing an anti-dumping case against China without derailing the wider relationship has become a genuine diplomatic assignment.
What happens next
The immediate milestones are fixed by statute. Exporters and importers will spend the autumn responding to CBSA requests for information ahead of the final determinations due November 23. The Canadian International Trade Tribunal’s injury finding follows by December 22. If either the dumping and subsidy findings or the injury finding fails, the provisional duties collected since August 24 would be refunded. If both are confirmed, definitive duties will lock in for years, and the decorative plywood trade between China and Canada will be permanently reshaped.
For importers, the near-term advice from customs professionals is unambiguous: audit every plywood shipment released since August 24, map products against the definition and exclusions, identify the exporter and applicable rate, verify CARM assessments, and consider whether sourcing can shift to excluded products, non-subject countries, or the handful of Chinese exporters with low company-specific rates. Contracts for autumn and winter delivery should address which party bears provisional duty risk and what happens if rates change at the final determination.
For the broader Canadian trade community, the plywood case is a useful corrective to the idea that trade policy is only what happens between prime ministers and presidents. While the political class fights the tariff war on cable news, the machinery of trade remedy law continues its quieter work, one product definition at a time, with stakes measured in the hundreds of percent.
How SIMA cases work, and why the numbers get so large
For readers outside the trade bar, the scale of the duties, up to 227.5 percent, can seem arbitrary. It is not. Under the Special Import Measures Act, the CBSA calculates two separate margins for each investigated exporter. The dumping margin measures how far below normal value, essentially the comparable home market or constructed price, the exporter sold into Canada. The subsidy amount measures the per-unit benefit conferred by government programs, from preferential loans and tax holidays to below-cost inputs such as timber and electricity. The provisional duty combines both.
Exporters who cooperate fully with the CBSA’s requests for information receive rates based on their own data, which is why the eleven named companies span a range from zero to 173.6 percent: their actual pricing and subsidy profiles differ. Exporters who do not respond, or respond inadequately, receive a rate constructed from the facts available, deliberately set high enough that non-cooperation confers no advantage. The 227.5 percent all-others rate is that instrument. It functions less as a measurement than as an incentive: cooperate, or be priced out of the market.
The provisional phase also builds in safeguards. If the CBSA’s final determinations in November find lower margins, provisional duties collected in the interim are adjusted and over-collections refunded. If the Canadian International Trade Tribunal finds in December that the dumping and subsidization did not injure Canadian producers, everything collected since August 24 is returned. Importers, in other words, are financing a contingent liability for the next four months, which is why trade counsel advise pricing provisional duty risk explicitly into autumn contracts rather than assuming the current rates are final.
The tribunal phase is also where the commercial arguments get their fullest airing. Canadian producers must demonstrate material injury, lost sales, price depression, reduced profitability, attributable to the subject imports. Importers and downstream users can contest causation, pointing to other market forces such as the construction slowdown or US trade diversion. The tribunal can also grant product exclusions where a specific item is not made in Canada, and exclusion requests for specialty veneers and niche panel formats are widely expected in this case.
The industry behind the complaint
Canada’s plywood and veneer industry is a small but strategically placed piece of the country’s forest economy, concentrated in Quebec, Ontario and British Columbia. Domestic producers of decorative panels have spent a decade arguing that subsidized Chinese product, often entering at prices below the Canadian cost of raw veneer, made fair competition impossible and hollowed out capacity that once served the furniture and cabinet trades.
The sector’s complaint gained force from the broader crisis in Canadian forest products. Softwood lumber producers have paid American anti-dumping and countervailing duties for years, with the US Department of Commerce’s seventh administrative review pushing combined rates higher and a final determination in the current review expected in October. American Section 338 tariffs added a further 50 percent wall in August. With export markets closing, Canadian mills increasingly depend on the domestic market, and the case for defending that market against dumped imports became correspondingly stronger, both economically and politically.
Downstream, the arithmetic is harsher. Canada’s cabinet, furniture and millwork manufacturers, thousands of mostly small firms concentrated in Ontario, Quebec and the Lower Mainland, built their supply chains on imported decorative panels. For them, the provisional duties are a supply shock arriving in the same season as the US trade war’s disruption of their export sales and hardware inputs. Industry associations are expected to intervene actively at the tribunal, seeking exclusions and arguing that injury to producers must be weighed against damage to a downstream sector that employs many times more workers.
Sourcing in a suddenly smaller world
The immediate commercial question for buyers is where decorative panel supply will come from this fall. The realistic options each carry complications. Domestic producers can expand output, but capacity in specialty decorative grades is limited and lead times are lengthening already. Southeast Asian suppliers, in Vietnam, Indonesia and Malaysia, offer alternatives, but buyers must scrutinize origin carefully: US circumvention cases have repeatedly found Chinese product transshipped or minimally processed through the region, and the CBSA can extend measures to circumventing imports through anti-circumvention proceedings. European panels are compliant but expensive, and transatlantic freight adds cost and time.
The eleven named Chinese exporters with company-specific rates present a narrower path. Goods from the zero-rated and single-digit exporters remain commercially viable, and brokers expect trade to concentrate rapidly toward those suppliers. That concentration carries its own risk: final determinations in November can move company-specific rates in either direction, and a buyer who signs a winter supply contract against a 0 percent provisional rate may face a different number by December.
Purchasing managers, in short, face a probabilistic sourcing problem with four moving variables: the final CBSA margins, the tribunal’s injury finding, possible exclusions, and freight markets already scrambled by the Canada-US conflict. The consistent advice from trade professionals is to diversify across at least two of the available paths rather than betting the product line on any single outcome.
A pattern, not an exception
The plywood case is also best understood as part of a broader quickening of Canadian trade remedy activity. As global overcapacity in steel, aluminum, solar equipment and wood products collides with closing markets elsewhere, Canada has become a destination of concern for diverted goods, and Canadian industries have responded with a steady drumbeat of SIMA complaints. Measures against Chinese steel, aluminum extrusions, solar modules and wind towers already dot the landscape, and the federal government has in recent years tightened the system itself, adding anti-circumvention procedures and expanding the CBSA’s ability to initiate reviews.
Ottawa’s 2024 decision to impose surtaxes on Chinese electric vehicles, steel and aluminum outside the SIMA process signalled political willingness to act against Chinese trade practices even at diplomatic cost. The January 2026 accommodation with Beijing recalibrated that stance but did not repeal it. What has emerged is a two-track policy: political management of the headline relationship, and undiminished enforcement in the technical trenches. The plywood determinations, arriving seven months after the Carney-Xi agreements, are the clearest evidence yet that the second track runs on its own schedule.
For Canadian importers and manufacturers, the operational lesson of this week is the same one the US counter-tariff list taught days earlier: the era of assuming stable landed costs is over. Duty exposure has become a live variable in every sourcing decision, from Ohio appliances to Shandong veneer, and the companies navigating this decade successfully are the ones treating trade compliance not as paperwork but as strategy.
