Canada has expanded its trade response against the United States with new counter-tariffs covering pulp, paper and converted paper products, adding another layer of uncertainty to the highly integrated North American forest-products supply chain.

The measures will take effect at 12:01 a.m. on September 8, 2026 and apply rates of 15%, 25% or 50%, depending on the product. Canada says the individual rates are designed to match corresponding U.S. tariffs. In total, the countermeasures will cover C$27.6 billion of U.S. imports.

For the paper industry, the detailed tariff schedule confirms that the measures go well beyond a general reference to “pulp and paper.” Specific grades and converted products are now listed, including kraft paper, coated paper, tissue, corrugated boxes and paper foodservice packaging.

Paper Products Face Tariffs as High as 50%

Canada’s official tariff schedule includes several paper and packaging categories.

Among the products subject to the measures are uncoated kraft paper and paperboard, with certain grades facing a 25% tariff.

Other paper products are subject to the highest 50% rate.

These include certain coated printing and writing papers, as well as other coated, impregnated or surface-treated paper and paperboard products.

Converted paper products are also directly affected.

The list includes envelopes, certain household and sanitary paper products, corrugated cartons and boxes, paper bags and certain paperboard trays, dishes, plates and cups, with several of these categories facing a 50% tariff.

The measures therefore reach multiple stages of the paper value chain rather than concentrating only on commodity pulp or base paper.

Toilet Paper and Tissue Are Included

One of the more consumer-visible parts of Canada’s response concerns tissue products.

Canada’s list includes tariff heading 4818, covering products such as toilet paper and other household or sanitary paper articles, with listed items subject to a 50% surtax.

That means the trade dispute could move beyond industrial raw materials and become visible in finished consumer-paper markets.

How much of the additional cost ultimately reaches retail prices will depend on sourcing contracts, inventories, Canadian production capacity and whether importers can shift purchases toward suppliers outside the United States.

For Canadian tissue converters and retailers relying on U.S.-made finished products or intermediate materials, procurement strategies may therefore need to be reassessed before the tariffs take effect.

Corrugated Packaging Also Faces 50%

The tariff list also covers cartons, boxes and cases made from corrugated paper or paperboard, which will face a 50% rate.

This is significant because corrugated packaging is embedded throughout manufacturing, food, agriculture, retail and e-commerce supply chains.

A tariff on imported corrugated boxes is therefore not confined to the packaging industry itself.

Companies purchasing U.S.-made boxes for Canadian operations could face higher landed costs, while domestic corrugated producers may gain some insulation from competing U.S. imports.

The real effect will vary by region because corrugated packaging is relatively bulky and frequently produced close to end markets. Cross-border trade nevertheless remains important for some customers and plants located near the Canada-U.S. border.

Paper Cups and Foodservice Packaging Are Caught in the Measures

Canada’s response also covers certain paper or paperboard trays, dishes, plates and cups, with affected tariff items carrying a 50% rate.

That adds another trade issue for Canada’s foodservice packaging sector.

The country has already opened separate dumping and subsidy investigations into certain paperboard cups and containers imported from China.

Now selected U.S.-made paper foodservice products also face new tariff exposure.

For Canadian buyers, these developments could increase the strategic importance of domestic production and alternative overseas sourcing.

They may also influence the competitive balance among U.S., Canadian and Asian suppliers.

Canada Says the Measures Are Dollar-for-Dollar Retaliation

The Canadian government describes the tariffs as a direct response to the United States’ decision to impose 50% duties on C$27.6 billion of Canadian goods effective August 22.

Canada says it will match those measures dollar for dollar.

The new package focuses on sectors that Ottawa says have been heavily affected by U.S. trade action, including steel, dairy, appliances, agricultural equipment, pulp and paper and electronics.

Alongside the tariffs, Canada announced a C$7.5 billion support package for workers and businesses affected by U.S. measures.

The government says the objective is to protect Canadian producers and workers rather than simply generate tariff revenue.

North American Paper Supply Chains Face New Friction

The pulp and paper industries in Canada and the United States have developed around deeply interconnected trade flows.

Market pulp, paperboard, tissue, printing papers, packaging and converted products can cross the border as either raw materials or finished goods.

That means tariffs at one stage can affect operations somewhere else in the value chain.

A Canadian packaging converter, for example, may purchase U.S. paper or board because of a particular specification or geographic proximity.

A retailer may source U.S.-made tissue.

A Canadian manufacturer may use U.S.-made corrugated packaging around a product assembled domestically.

The new tariffs can change the economics of each of those relationships.

Domestic Producers Could Gain, but Buyers Face Higher Costs

For Canadian producers competing directly with U.S. imports, the tariff package could improve relative price competitiveness in the domestic market.

Domestic tissue, paperboard or packaging manufacturers may find imported U.S. alternatives considerably more expensive after September 8.

But there is another side to that equation.

Canadian companies that depend on U.S. grades not readily available domestically could experience higher input costs.

The consequences will therefore differ substantially across the industry.

The same tariff that benefits one Canadian paper producer could increase costs for a downstream converter.

That is why the precise tariff-line schedule matters far more than the broad phrase “pulp and paper tariffs.”

September 8 Becomes a Major Procurement Deadline

Companies now have a short period to review exposure before the tariffs take effect.

Canada says the countermeasures will apply only to goods originating in the United States and will not apply to U.S. goods already in transit to Canada when the tariffs enter into force.

For importers, that makes product classification, country of origin and shipment timing immediately relevant.

The next task for paper, packaging and tissue companies is therefore operational:

identify the affected HS codes, determine which U.S. suppliers are exposed, calculate the new landed cost and decide whether alternative sourcing is commercially viable.

What began as a broader Canada-U.S. political dispute is now reaching directly into paper purchasing decisions.

For the North American forest-products industry, the September 8 measures turn trade policy into a line-by-line cost issue across pulp, paper, tissue and packaging.
