A Canadian mould maker has become a vivid example of how quickly tariff policy can turn a signed price into a moving target. Cavalier Tool & Manufacturing, a Windsor, Ontario producer of plastic-injection moulds, told a House of Commons committee in April that it was going back to customers for roughly 15% more when projects reached the shipping stage because new U.S. duties had changed the economics after quotes were issued.

The headline 50% rate needs context. Washington’s Section 232 regime raised tariffs on many steel and aluminum products to 50%, while later rules applied different rates to certain derivative products and industrial machinery. For Cavalier, the practical problem was less a single number than repeated rule changes, rising input pressures and duties applied to finished equipment. Months later, the company was still describing U.S. tariff uncertainty as a major pricing challenge.

A 15% Increase Appeared After the Quote Was Already Set

Cavalier’s April testimony showed why the phrase “raising prices” does not quite capture what was happening. International business manager Chris Vander Park said the company had not simply rewritten every quotation. Instead, it was keeping the quoted price intact and confronting the additional tariff expense when a completed mould was ready to cross the U.S. border. At that point, Cavalier was returning to customers and telling them it needed roughly 15% more to cover the changed cost structure.

Vander Park compared the situation to agreeing on the price of a new vehicle, arranging the purchase and returning to collect it only to discover the final price was 15% higher. The analogy is especially relevant for injection moulds because they are negotiated months before delivery. Customers may already have approved capital budgets and planned production around an agreed figure. When government charges change the landed cost late in that process, both manufacturer and customer are forced into another negotiation neither expected when the order was placed.

Why the 50% Tariff Headline Needs Careful Context

The U.S. metal tariff story developed in several stages. In June 2025, the White House increased Section 232 tariffs on steel and aluminum articles and many derivative products from 25% to 50%. An April 2026 proclamation changed the system further, including how tariffs were calculated for certain products. Many covered steel and aluminum goods remained subject to the headline 50% rate, while specified industrial machinery and power equipment received temporarily reduced tariff treatment.

That distinction is critical in understanding Cavalier’s experience. Parliamentary testimony described certain moulds as machinery or industrial equipment facing a 15% tariff on their full value, rather than a 50% tariff on the entire finished mould. Previously, mould makers described paying the 50% tariff on the value of steel contained in certain products. Washington changed the rules again in June, modifying treatment for additional industrial equipment. The practical outcome is a complicated regime in which classification, origin, timing and product type can matter just as much as the headline tariff percentage.

A Custom Mould Can Be Months Into Production Before the Cost Changes

Cavalier’s business model makes abrupt trade-policy changes particularly disruptive. The company told MPs that injection moulds are custom-engineered capital assets designed and manufactured over many months, requiring thousands of hours of skilled work. Pricing, production scheduling and machine capacity are committed well before a finished tool is ready for shipment. By the time a tariff rule changes, materials can already be purchased, machining can be well underway and the customer’s own production timetable may already depend on delivery.

That leaves manufacturers with little room to respond without affecting margins or customers. Cavalier said repeated rule changes forced it to add new wording to every quotation stating that tariffs, duties and government-imposed surcharges were not included and would be the customer’s responsibility at shipment. The company operates three facilities in Windsor, with its third plant having completed a major expansion in January 2025. That investment highlights the mismatch between industrial planning, which happens over years, and tariff rules capable of changing during a single production cycle.

One Tool Went From a Manageable Charge to a Five-Figure Problem

The scale of the change became clearer when Cavalier discussed individual projects. During the April parliamentary hearing, an MP described a mould worth roughly US$244,000 that involved about 1,500 hours of labour. The expected tariff on the tool had previously been approximately US$1,500. After changes to the Section 232 system, the tariff was estimated at about US$36,000. Vander Park confirmed those figures and said the completed tool had still not shipped.

Several projects together produced an even larger difference. Vander Park said four tools negotiated with a customer the previous May had been priced under an arrangement in which Cavalier agreed to absorb the anticipated tariffs. Based on the rules expected at the time, the tariff bill was estimated at US$25,375. By the April committee appearance, he said those same four tools would face US$130,347 in tariffs if they shipped that day. A change of that magnitude can turn an otherwise profitable contract into an immediate argument over who is responsible for a cost that did not exist when negotiations began.

Passing the Cost Along Does Not Solve the Cash-Flow Problem

Even when a customer ultimately agrees to cover a tariff, the Canadian manufacturer can still face an immediate financing problem. Cavalier chief financial officer Diane Ricci Woodiwiss told MPs that the company could not absorb an additional 15% on its jobs because its margins were too tight. She explained that once a tool shipped to the United States, the company had to pay the tariff within roughly 10 days and then invoice its customer for reimbursement.

That timing creates pressure in a capital-intensive industry. Steel, skilled labour, machining time, electricity and other operating costs are incurred long before a large mould generates its final cash payment. Woodiwiss said Cavalier was negotiating payment terms with customers and expected that, in some cases, the company would make the initial tariff payment and then hope to be reimbursed afterward. Management consequently had to conserve cash rather than commit it elsewhere. A tariff therefore does more than increase a product’s final price: it can temporarily consume working capital that otherwise might have funded machinery, hiring, maintenance or new projects.

Investment and Hiring Were Among the First Things Put on Hold

Cavalier’s response quickly moved beyond customer pricing. Woodiwiss told the parliamentary committee that the company had been considering a roughly C$4-million expansion in 2026 but had paused the project. Plans to buy additional equipment were also stopped. Cavalier was moderating shifts and had stopped hiring new employees, although Woodiwiss said at the time that the company had not begun layoffs. Management was instead trying to retain skilled tradespeople who can be difficult to replace.

Vander Park said Cavalier still had approximately three or four months of work in progress because existing contracts had to be completed. The problem was what came afterward. Sales staff were struggling with questions about how future jobs could be quoted when the tariff payable months later remained uncertain. In advanced manufacturing, those decisions are interconnected. A new machine can require another operator, a factory expansion may depend on anticipated orders and a large customer program may justify both. When confidence in future pricing falls, several investments can be postponed at the same time.

The U.S. Market Is Too Important for Canadian Manufacturers to Ignore

Cavalier’s experience sits inside one of the world’s most integrated manufacturing relationships. Statistics Canada estimated that Canadian manufacturers shipped C$324 billion worth of goods to the United States in 2024. U.S. demand accounted for C$113 billion in Canadian manufacturing value added and roughly 694,000 payroll jobs. That was equivalent to 42.4% of manufacturing industry value added and 41% of its payroll employment, illustrating the enormous exposure Canadian factories have to American demand.

The supply chain also works in both directions. Statistics Canada found that more than one-quarter of the value of Canadian manufactured goods shipped to the United States in 2024 represented embedded imported content from the U.S. This makes the relationship more complex than a simple exporter-versus-importer story. Cavalier itself described operating inside a highly integrated North American supply chain. Its moulds support industries including automotive manufacturing, commercial goods, agriculture, recreational vehicles, construction and aerospace. For specialized manufacturers, changing customers or reorganizing sourcing across borders can therefore take considerably longer than changing a tariff rate.

Customers Can Delay Orders Long Before They Cancel Them

Tariff pressure does not have to result in an immediate factory closure to alter manufacturing activity. Cavalier told MPs that customers were delaying decisions as uncertainty increased. Its new quotation language also meant buyers had to consider costs that could not be known precisely until shipment. That makes it harder for a customer to approve a capital purchase months in advance, especially when the tool itself can cost hundreds of thousands or even millions of dollars.

The uncertainty remained visible later in 2026. In August, Vander Park told Windsor radio station AM800 that Cavalier was still affected by earlier Section 232 measures, with some injection moulds carrying tariffs in the 10% to 15% range. He illustrated the problem with a US$1-million mould: a 15% tariff adds another US$150,000 to the customer’s capital expenditure. A buyer that budgeted US$1 million may not have an additional US$150,000 readily available. In that situation, delaying the project can become easier than immediately cancelling it, leaving the manufacturer with less certainty about its future production schedule.

Cavalier Is Not the Only Manufacturer Trying to Protect Its Margins

Industry surveys suggest Cavalier’s reaction is part of a wider pattern. Canadian Manufacturers & Exporters reported in June that among manufacturers affected by the April U.S. metal tariff changes, 74% described the effect as moderately or significantly negative. Fifty-five per cent said they were absorbing tariff-related costs or reducing margins, while 48% reported raising prices for U.S. customers. Another 47% reported lost or reduced U.S. sales, and 30% were delaying, reducing or cancelling planned Canadian investment.

A separate KPMG Canada survey of 275 manufacturing decision-makers, conducted in May, found 57% had paused, reduced or cancelled capital spending projects because of economic uncertainty and trade or tariff threats. Twenty-nine per cent said their companies had already moved some or all production to the United States, while another 13% said they planned to move some production. The two surveys cover different groups and should not be treated as forecasts for every factory, but both show manufacturers reconsidering prices, investment and production footprints as trade costs become harder to predict.

The Tariff Bill Is Still Moving Through the Supply Chain

The trade environment has continued changing since Cavalier gave its parliamentary testimony. Canada introduced another round of counter-tariffs effective September 8, 2026, with rates of 15%, 25% and 50% on specified U.S.-origin goods targeted in response to American Section 338 and Section 232 measures. The Canadian government said the measures covered C$27.6 billion of U.S. imports and included products in sectors such as steel, appliances, agricultural equipment, electronics, dairy and pulp and paper.

Broader manufacturing numbers, meanwhile, remain mixed rather than pointing to a simple sector-wide collapse. Statistics Canada reported that manufacturing sales declined 0.4% in July to C$78.7 billion after five consecutive monthly increases, although nominal sales were 10.9% higher than a year earlier. In constant dollars, July manufacturing sales fell 1.4% from June. For a company such as Cavalier, however, the immediate problem is more specific than the national headline numbers: a manufacturer must quote a price today that still makes economic sense when a custom-built product crosses the border several months later.
