Packaging supply chains face renewed tariff pressure

The escalating trade dispute between the United States and Canada is creating fresh uncertainty for North America's packaging industry, with tariffs expected to increase costs for manufacturers and companies that depend on cross-border flows of raw materials and finished packaging. The latest measures are particularly significant for fibre, metal and glass packaging, sectors that rely heavily on integrated supply chains between the two countries.

Canada has announced tariffs of up to 50% on a range of materials and goods imported from the United States, following the introduction of similar US tariffs. The measures are expected to affect businesses on both sides of the border as manufacturers reassess sourcing strategies, inventories and production costs.

Fibre packaging faces major disruption risks

The North American pulp, paper and packaging industries are particularly exposed because their supply chains have developed around extensive cross-border trade. Mills, converters and packaging manufacturers regularly move raw materials and finished products between the United States and Canada, making the sector highly dependent on predictable trade conditions.

Industry representatives have warned that tariffs on pulp, paper, containerboard and other fibre products could increase costs while disrupting established supply routes. The Canadian corrugated and containerboard industry has also highlighted the importance of cross-border trade, arguing that disruption could affect not only packaging manufacturers but the many industries that depend on corrugated boxes for transportation.

Aluminium and steel face additional costs

Metal packaging is also vulnerable to the latest measures. Canada is preparing to increase tariffs on metal imports, while the United States continues to apply substantial duties to aluminium, steel and related products.

The situation is particularly significant for aluminium because the US packaging industry relies heavily on Canadian primary aluminium. The metal is widely used in beverage cans, food packaging and other applications, meaning higher input costs could eventually move through the packaging supply chain and affect manufacturers, brands and consumers.

Although the United States is increasing domestic aluminium production and recycling capacity, new primary production requires significant investment and cannot immediately replace imported material. This leaves manufacturers exposed to short-term price and availability pressures.

Glass packaging caught in a wider dispute

Glass packaging has also become increasingly exposed to the deteriorating relationship between the two countries. Although Canada's latest tariff measures do not specifically target all glass products, the sector is already experiencing disruption linked to trade restrictions and a Canadian consumer boycott of US-produced alcoholic beverages.

The North American glass packaging supply chain is highly integrated, with significant volumes of bottles and jars moving between Canada and the United States. Additional tariffs could therefore increase costs for manufacturers while placing further pressure on a market already affected by weaker demand in some beverage categories.

Companies consider mitigation strategies

Packaging companies are already assessing ways to reduce the potential impact of tariffs. Some businesses are reviewing sourcing strategies, while others are considering bringing forward purchases or shipments before new duties take effect. However, the rapidly changing nature of the trade measures makes long-term planning difficult.

Companies with manufacturing operations on both sides of the border may also have greater flexibility to adjust production and material flows. Nevertheless, shifting supply chains requires time and investment, particularly for packaging materials that depend on specialised mills, smelters or manufacturing facilities.

Higher costs could reach consumers

As packaging materials become more expensive, manufacturers face difficult decisions about whether to absorb additional costs, negotiate with suppliers or pass increases through to customers. Packaging represents an important input across food, beverage, consumer goods and industrial supply chains, meaning sustained increases can ultimately affect product prices.

Corrugated packaging is particularly important because virtually every major product category relies on boxes for transportation and distribution. Disruption to the fibre supply chain could therefore have effects extending well beyond the packaging sector itself.

Resilience becomes a strategic priority

The latest US-Canada tariff escalation demonstrates the growing importance of supply-chain resilience for packaging manufacturers. Companies are being forced to consider not only material prices and availability but also geopolitical risks, trade policy and the concentration of their supplier networks.

For the North American packaging industry, maintaining flexibility in sourcing and production could become increasingly important as trade policies continue to evolve. While tariffs may create short-term cost pressures, they could also accelerate efforts to diversify supply chains, increase domestic recycling and develop more resilient regional packaging markets.
