US Importers Sue Over Canada Tariffs

CANADA · ANALYSIS

The importers tariff lawsuit Canada case is an early test of whether President Donald Trump can use a rarely invoked 1930 statute to impose sweeping tariffs without the limits Congress later attached to presidential trade powers. A ruling could determine whether US importers recover millions of dollars in duties and whether retailers, restaurants and consumers continue absorbing higher costs on Canadian food and other goods.

Canada is the United States’ largest trading partner, and the two economies move goods across the border through tightly integrated supply chains. This analysis explains the legal fight over 50% duties on Canadian cheese, wine, cement and other products, drawing on the USA & Canada Intelligence Brief published on 30 October 2026.

The Lawsuit and Its Claims

Gellert Global Group Corp., a New Jersey-based food importer, filed suit on 20 October 2026 in the US Court of International Trade, known as the CIT. The company imports Canadian cheeses including brie, camembert, mascarpone and goat- and sheep-milk products.

The complaint, brought by the Liberty Justice Center, seeks a declaration that the tariffs are unlawful, an injunction blocking their enforcement and collection, and refunds with interest for duties already paid. It also asks for class-action treatment for importers that paid or will pay the duties on covered Canadian goods.

Gellert says it now faces an estimated US$40 million annual tariff bill under the new 50% duties. The complaint reportedly says the company paid at least US$520,538 in duties on 22 shipments between 16 September and 11 October 2026.

The proposed class has not been certified, and the court has not yet ruled on the merits or the request for preliminary relief. That makes the case an early procedural test as much as a substantive one.

The Legal Basis for the Tariffs

On 20 July 2026, President Trump issued proclamations imposing additional 50% ad valorem tariffs on selected Canadian goods, including wine, dairy products, cement, clothing, fishing equipment and hockey products. The tariffs were announced for August 19, 2026, suspended on August 18, and took effect on August 22, 2026; the 30-day period applied to certain later-listed goods, and the duties applied even to goods that otherwise qualified for preferential treatment under the United States-Mexico-Canada Agreement, or USMCA.

The administration relied on Section 338 of the Tariff Act of 1930, codified at 19 U.S.C. §1338. That provision allows the president, after finding that a foreign country discriminates against US commerce or places it at a disadvantage relative to another country, to impose additional duties of up to 50%.

The White House said the measures were intended to offset what it characterised as Canada’s discriminatory treatment of US commerce, including barriers affecting American alcohol, dairy and vehicle exports.The importers argue that later legislation, particularly Section 301 of the Trade Act of 1974, displaced or impliedly repealed the older Section 338 authority for this type of retaliation.

The government is likely to respond that Congress never expressly repealed Section 338 and that the statute remains valid unless and until Congress removes it.

The Courts’ Role and the Separation of Powers

The CIT is the specialised federal court for disputes involving customs duties, imports and trade remedies. It is therefore the natural first forum for an importer seeking to stop collection and recover duties.

The case could proceed through several stages. The administration may oppose Gellert’s request for a preliminary injunction, and the court may decide whether Gellert has shown immediate commercial harm and a likelihood of success.

The judge may also address whether the proposed importer class can be certified. The CIT could uphold the tariffs, invalidate them, or strike down only particular proclamations, products or effective dates.

The losing party could appeal to the U.S. Court of Appeals for the Federal Circuit, with possible further review by the Supreme Court. A preliminary injunction would not necessarily be a final victory, but it could temporarily suspend collection while the court examines the statutory and constitutional issues.

The complaint also places the tariffs within the larger constitutional debate over presidential control of trade. The Constitution gives Congress the power to regulate commerce and impose duties, while Congress has delegated portions of that authority to presidents through statutes such as Sections 232, 301 and 338.

Effects on Prices and Supply Chains

A successful challenge would not automatically return prices to pre-tariff levels, but it could remove a major cost imposed at the border. Importers usually decide how to divide tariff costs among suppliers, distributors, retailers and customers.

For a product facing a 50% duty, the immediate effects can include higher wholesale prices for Canadian cheese, wine and other covered products, reduced margins for importers and specialty retailers, and substitution toward US, European or other foreign suppliers. Smaller package sizes, fewer premium products and higher restaurant and food-service costs are also likely.

Gellert’s estimated US$40 million annual burden illustrates the scale for one importer, although that figure is company-specific and should not be treated as the total consumer cost. If the tariffs remain in force, the impact is likely to be most visible in product categories with limited short-term substitutes, such as specialty cheeses and Canadian alcoholic beverages.

Border states may experience the effects disproportionately because their businesses rely heavily on short-haul Canada-US trade. Retailers, trucking companies, customs brokers, cold-storage operators and food manufacturers can all be affected even when they do not directly pay the tariff.

The dispute also creates risk for firms selling US goods into Canada. Ottawa has responded with dollar-for-dollar retaliation, meaning US exporters may face higher Canadian prices and weaker demand at the same time that US importers face higher costs.

What It Means for the United States and Latin America

For US readers, the case is a direct test of how much tariff power a president can exercise without fresh congressional approval. A ruling against the administration could constrain future tariff actions under other statutes, not just the Canada measures.

For Latin America, the case matters because the legal standard applied to Section 338 could shape how Washington uses trade retaliation more broadly. Countries that export food, beverages, cement and other goods to the United States may watch whether the court requires more precise findings before sweeping duties can be imposed.

Canada-United States trade remained mostly tariff-free, but failed negotiations had resulted in new tariffs and increased uncertainty. That uncertainty is now spilling into US courtrooms and boardrooms.

The Scenarios

One scenario is that the CIT grants a preliminary injunction, temporarily suspending collection while the court examines the statutory and constitutional issues. That would reduce near-term uncertainty for importers and could pressure the administration to negotiate a narrower tariff list.

Another scenario is that the court allows collection to continue, signalling that duties will probably remain in force during the litigation. Importers may still preserve claims for refunds depending on how entries are liquidated and how the litigation proceeds.

A negotiated settlement could remove or reduce the tariffs before final judgment. For businesses, however, a political settlement may not resolve whether previously paid duties are refundable, so the court case remains relevant even if the tariff list changes.

The most consequential outcome would be a ruling that limits the use of Section 338 or requires more precise congressional authorisation for broad tariff programs. Such a decision could affect future tariffs imposed under other statutes, not just the Canada measures.

What It Means for You

If the tariffs fall, specialty cheese, wine and other Canadian goods could become cheaper at US retail, though price relief may lag by months because inventories, contracts and distributor markups would remain in the system. A removal could lower landed costs quickly for new shipments, but retail prices might adjust more slowly.

If the tariffs stay, expect higher wholesale prices for Canadian cheese, wine and other covered products, reduced margins for importers and specialty retailers, and substitution toward US, European or other foreign suppliers. Smaller package sizes and fewer premium products are likely in affected categories.

Businesses that import covered Canadian goods should monitor whether the court permits the case to proceed on a class basis. If not, affected companies may need to preserve separate claims and carefully monitor customs-entry liquidation deadlines.

What Is Not Known

The available sources do not identify a publicly confirmed hearing date, briefing deadline or judgment date for the Gellert action. The court’s docket will determine the pace of preliminary relief and any class-certification decision.

It is not yet known whether the administration will oppose the preliminary-injunction request or seek to narrow the case by modifying the tariff list. The complete official tariff-line annex and the Canadian retaliation schedule are not available in the verified research.

Those details will matter for calculating refunds and for understanding which products face the highest effective costs.

What to Watch

The first market-moving development is likely to be the CIT’s treatment of the preliminary-injunction request. A temporary halt would reduce near-term uncertainty for importers, while denial would signal that duties will probably continue during the litigation.

Businesses should track which products were added or modified on 8 September and 15 September, and whether Customs and Border Protection collected duties before the legally permitted date. The seven-day implementation period is a legal issue: products first listed on September 8 began incurring tariffs on September 15, although Section 338 allegedly requires a 30-day waiting period.

Importers should watch whether the court permits the case to proceed on a class basis. If not, affected companies may need to preserve separate claims and carefully monitor customs-entry liquidation deadlines.

Further revisions to the tariff list could narrow the case, create new claims or complicate refund calculations. A negotiated settlement could remove or reduce the tariffs before final judgment, but it may not resolve whether previously paid duties are refundable.

Frequently Asked Questions

What is the importers tariff lawsuit Canada case about?

Gellert Global Group, a New Jersey food importer, sued the Trump administration on 20 October 2026 over 50% tariffs on Canadian goods. The company argues that the administration exceeded presidential tariff authority by using Section 338 of the Tariff Act of 1930 to impose broad duties.

What legal grounds are importers using to challenge the tariffs?

Importers argue that Section 338 was effectively superseded by later trade legislation, that the administration did not satisfy the statute’s factual findings and procedural requirements, and that the tariffs are not properly tied to the actual burden allegedly caused by Canadian measures.

How much are the tariffs costing importers?

Gellert says it now faces an estimated US$40 million annual tariff bill under the new 50% duties. The company reportedly paid at least US$520,538 in duties on 22 shipments between 16 September and 11 October 2026.

What could a ruling change for prices and trade?

A ruling against the administration could produce refunds, lower import costs and constrain future presidential tariff actions. A ruling for Washington would validate one of the broadest uses of Section 338 in modern trade policy, leaving US importers and consumers exposed to continued 50% duties.

Which products are covered by the 50% tariffs?

Reported categories include cheese and other dairy products, wine and other alcoholic beverages, furniture, cement, clothing and apparel, fishing rods and tackle, hockey equipment, and honey. Exact coverage depends on the applicable tariff-line schedule.

What should businesses watch in the coming months?

Businesses should watch the CIT’s treatment of the preliminary-injunction request, the effective-date dispute over the alleged seven-day implementation period, and whether the court permits the case to proceed on a class basis. Further revisions to the tariff list could also narrow the case or create new claims.
