WASHINGTON, United States – President Donald Trump has removed selected Canadian products from an additional 50% tariff list, offering potential relief to US businesses that rely on Canadian packaging, machinery and agricultural supplies.
Trump signed the proclamation on October 23, 2026. The changes take effect on October 30, just four days before the November 3 midterm elections.
The decision could benefit farmers and businesses in Maine, where Republican Senator Susan Collins has pushed the administration to ease tariffs on products used by blueberry, potato, apple and seaweed producers.
But the move is selective. It does not end US tariffs on Canadian goods generally. The proclamation also adds other Canadian products to the additional tariff list, leaving parts of the wider trade dispute unresolved.
Which Canadian goods receive relief?
The White House says the proclamation removes specified products from the additional 50% duties imposed under Section 338 of the Tariff Act of 1930.
The affected categories include plywood sheets, certain paper products, machinery, refrigeration and freezing equipment, and some packing crates and boxes. These products are used by businesses that depend on Canadian suppliers for equipment, packaging and production materials.
Senator Collins said the exemptions cover nine categories important to Maine’s agricultural and coastal industries. She highlighted the needs of blueberry, potato, apple and seaweed producers, who use Canadian products that may be difficult or expensive to replace with US alternatives.
The proclamation also adds certain valves, carpets, waste products and other goods to the additional tariff list. The exact coverage depends on the tariff classifications in its annexes. Not every product that falls under a broad description is necessarily covered.

The 50% tariff is not the only duty
The changes remove a specific additional tariff. They do not automatically eliminate every duty on the affected imports.
The proclamation states that the Section 338 duties apply in addition to tariffs imposed under Section 232 of the Trade Expansion Act of 1962. Other applicable import duties and requirements may also remain.
The measure also applies to covered goods regardless of whether they qualify as originating under the US-Mexico-Canada Agreement, according to the White House fact sheet.
For importers, that means the October 30 change could lower the duty burden on eligible products without making those goods entirely tariff-free. Businesses must check the relevant tariff classification and other applicable duties before calculating their savings.
Why Maine businesses sought relief
Maine’s economy has close commercial ties with Canada. Farmers and processors often rely on cross-border supply chains for equipment and materials used during planting, harvesting, packing and storage.
Collins said she repeatedly raised the issue with US Trade Representative Jamieson Greer, Commerce Secretary Howard Lutnick and other senior administration officials. She argued that some Canadian products were unavailable from US suppliers or would be costly to replace.
For blueberry producers, specialized boxes and harvesting equipment can be important during a short seasonal window. Potato and apple growers also rely on machinery, refrigeration and packaging to handle crops and prepare them for market. Seaweed businesses may benefit from changes affecting products and equipment used in processing and packaging.
The exemptions could reduce costs for businesses that import eligible goods directly or purchase them from suppliers who pass on some of the savings.
However, the scale of the benefit remains uncertain. It will depend on which products each business imports, how much it pays in duties, whether alternative suppliers are available and how companies adjust their prices.
No general reduction in retail prices should be assumed. Importers may use the savings to rebuild margins, absorb earlier cost increases, invest in their operations or lower prices. The outcome will vary by business and market.
How US importers pay tariffs
US import tariffs are generally collected from the importer of record when goods enter the country. Canadian exporters do not automatically pay the US duty directly to the US government.
The economic cost can still spread across the supply chain. An importer may absorb the duty, negotiate a lower price with its supplier, pass some of the cost to a US manufacturer or retailer, or raise prices for customers.
That is why the new exemptions could matter beyond the businesses named by Collins. A US company that uses Canadian packaging or machinery may face lower input costs if the goods it imports qualify for relief.
But the change does not guarantee that the full amount of the former tariff will be passed on to consumers. Contract terms, competition, inventory purchased before the effective date and the availability of alternative supplies can all affect the result.
The wider US-Canada trade dispute
The latest adjustment follows a breakdown in US-Canada trade negotiations earlier this year. The White House says Canada imposed new retaliatory tariffs on about $20 billion of US exports after talks stalled.
The Trump administration introduced the additional Section 338 duties in July and modified the covered products in September. Canada’s countermeasures and the continuing dispute have increased pressure on businesses that depend on cross-border trade.
The White House describes the new proclamation as an effort to offset the burden on US commerce while continuing to respond to what it calls discriminatory Canadian trade measures.
That is the administration’s stated rationale. The proclamation does not represent a comprehensive trade agreement, and the targeted exemptions do not resolve the broader disagreement over tariffs and retaliation.
Trump said on October 23 that Canada was working toward a trade deal with the United States. The status and terms of any wider agreement remain important questions for businesses planning future imports and exports.
Political significance ahead of the midterms
The announcement comes at a sensitive point in the US election calendar. Collins is seeking another Senate term in Maine, where her race against Democrat Troy Jackson is closely watched.
Collins publicly claimed credit for pressing the administration to provide relief. She said she had raised the burden on Maine businesses and families and would continue to seek further exemptions and a broader trade agreement.
Her Democratic challenger has criticized the limited nature of the relief, arguing that selective exemptions do not resolve the wider economic pressures caused by the tariffs.
The decision may give Collins an opportunity to demonstrate that she can influence trade policy. Reporting has also highlighted the potential benefit for other Republicans in states where businesses and voters have been affected by the dispute with Canada.
However, the timing alone does not establish that the administration designed the change to influence election results. The White House says it is adjusting tariffs to protect US commerce and respond to Canadian measures. Claims about electoral motives should remain attributed to the people making them unless further evidence establishes the administration’s intent.
The broader political issue is whether targeted relief can ease pressure on particular industries while the administration maintains its wider tariff strategy. Businesses that remain exposed to the duties may see little benefit from the changes.
What businesses should check before October 30
Importers should review the tariff classifications listed in the proclamation’s annexes and confirm whether their products qualify for removal from the additional 50% duty.
They should also check the entry date, any applicable Section 232 duties and other import requirements. Goods that do not match the listed classifications may remain subject to the additional tariff.
Businesses should not assume that a product is exempt simply because it is used by a farm, processor or manufacturer named in public statements. Eligibility depends on the legal product descriptions and tariff codes.
Canadian suppliers and US buyers may also need to revisit contracts, pricing and delivery schedules. The effective date could affect new shipments differently from goods already imported or entered for consumption.
Selective relief, not an end to the tariff dispute
The October 23 proclamation offers a limited change to the additional tariffs on Canadian goods. It could help Maine producers and other US businesses that rely on eligible packaging, machinery and materials.
The actual benefit will depend on product eligibility, import costs and how companies distribute the savings. Other tariffs may continue to apply, and the administration has added different Canadian products to the additional duty list.
With the midterm elections approaching, the announcement carries political significance. But its broader economic impact will depend on how businesses respond and whether the United States and Canada make further progress toward a trade agreement.
