After the implementation of the US policy of imposing a 50% tariff on imported aluminum, the backlash effect of the industry is spreading from the trade cost side to the physical production side. Novelis, a leading global aluminum rolling company, announced on September 18th that it will implement labor reduction measures at its aluminum rolling facility in Kingston, Canada. The layoffs will involve approximately 80 people, including 10 salaried employees and 70 hourly workers, accounting for one-third of the total workforce at the factory.
This adjustment is not a temporary production reduction measure. The factory will switch to a reduced operation mode. Novelis has stated that it will provide transitional support for affected employees while retaining room for flexible capacity recovery. If there is a substantial improvement in the market environment in the future, the production load will be re increased. It is worth noting that the factory completed the first round of personnel optimization with a scale of 21 people in June 2025. This layoff marks that the impact of high aluminum tariffs in the United States has officially penetrated into the long-term scheduling of regional aluminum processing capacity from the stage of cost compression.
Unbalanced distribution of tariff dividends: the smelting end benefits and the rolling end is under pressure
Previously, the market generally equated the aluminum tariff policy with the overall benefits of the North American aluminum industry, but the actual profit distribution of the industry chain showed significant differentiation: the upstream primary aluminum smelting process directly enjoyed the import substitution dividend, and the regional primary aluminum self-sufficiency rate and price premium rose synchronously.However, the aluminum rolling process is trapped in the dilemma of “cost conduction” bi-directional extrusion.
As a processing enterprise specializing in aluminum coils, sheets, automotive panels, and packaging foils, Novelis’ production costs are directly linked to the purchase prices of aluminum billets and remelted materials in the North American region. The 50% tariff has significantly increased the cost of aluminum raw materials arriving in the region, while downstream beverage packaging, automotive, and construction end customers have strong bargaining power. The cost increase in the processing process cannot be smoothly transmitted downstream, ultimately leading to a significant decrease in the operational economy of a single production line.
The enterprise is forced to match the current weak profit environment by reducing load and optimizing labor. Overall, the tariff policy has not achieved an increase in the overall industry chain revenue, but rather promoted the transfer of profits from the midstream rolling process to the primary aluminum smelting end.
Industry warning: Friction impact will show a long-term diffusion trend
Kevon Stewart, the director of the 6th district of United Steelworkers, publicly stated that this layoff is not an isolated event, and the pressure of capacity contraction in the North American aluminum processing industry will continue to be released in the coming months and even longer periods. The industrial protection brought about by current tariffs is a one-time policy shock, and the subsequent supply and demand rearrangement, capacity scheduling, and rule reconstruction of the entire industry chain will be a long-term process that lasts for many years. The scale of employment positions that policies claim to protect is far smaller than the actual employment volume corresponding to the affected processing capacity.
Core Tips for Global Aluminum Industry Investment Research
The analysis of aluminum prices needs to break through the single panel price dimension, focusing on tracking leading indicators such as aluminum premium in North America, aluminum shipping volume from Canada to the United States, and local rolling mill operating rates, in order to more accurately capture the marginal changes in regional supply and demand.
1. The profit distribution pattern of the industrial chain has been clearly restructured: the profit priority of the primary aluminum link is higher than that of recycled aluminum, and recycled aluminum is higher than that of the rolling processing link. The processing fees of sub categories such as canned goods, automotive sheets, and packaging foils will continue to be under pressure, and the gross profit of related processing enterprises will be squeezed for a long time.
2. After Canada’s continued obstruction of aluminum exports to the United States, processing capacity such as the Kingston factory located near the US Canada border will become a typical observation sample of tariff friction. The industrial path is likely to follow the order of “production reduction order transfer application for tariff exemption cautious capacity repair”.
3. Indirectly beneficial for domestic aluminum processing enterprises: North American domestic aluminum rolling capacity continues to withdraw and operations tend to be conservative, while the export substitution logic for aluminum plates, strips, and foils in the Middle East, Southeast Asia, and China will continue to be realized in the medium term.
Based on comprehensive analysis, the current 50% aluminum tariff policy has completed the initial honeymoon period of “protecting local employment” and officially entered the substantive stage of industrial cost sharing. Currently, the profits and employment opportunities in the midstream rolling process have become the main carriers of tariff costs.
The core observation points for follow-up industry tracking will focus on the progress of capacity recovery at the Kingston factory, the delivery cycle of Novelis North American automotive panels, the trend of US can material processing fees, and whether Canada can obtain phased tariff exemptions for US aluminum materials. Although the current factories have not been completely shut down, the competitive landscape of the North American aluminum processing industry is quietly reshaping.
