12.5% Tariff on Japanese Products, Canada Faces Wildfire Bills — The Shaking Rules of Free Trade

Even when stopped by the courts, tariff policy did not cease

The U.S. tariff policy has begun to move again, under a different legal basis.

In July 2026, the Trump administration introduced tariffs of 10% or 12.5% on goods imported from 60 countries and regions, including Japan, the European Union, China, South Korea, and Australia. The U.S. Trade Representative explained that the reason was that these countries were not sufficiently banning and cracking down on the import of goods produced by forced labor.

The imports from the targeted countries and regions account for over 99% of total U.S. imports. This means that rather than targeting specific problematic countries, it is effectively a policy to establish a new tariff floor at the entrance to the U.S. market.

What is important to understand about this measure is not just the tariff rate. The Trump administration chose a new legal route to continue its tariff-centered policy, even after a court ruling.

The previous broad tariffs were based on emergency presidential powers, but in February 2026, the U.S. Supreme Court ruled that the president had exceeded his authority, declaring the central part of it illegal. The administration then introduced a temporary 10% tariff for a limited period and switched the basis to Section 301 of the Trade Act of 1974.

Section 301 of the Trade Act is originally a system for investigating unfair trade practices and seeking corrections from the counterpart country. This time, the logic was that the insufficient ban on imports of goods produced by forced labor was unfairly restricting U.S. trade, and it was applied simultaneously to many trading partners.

Every time a legal basis is denied, a similar tariff system is reconstructed using a different clause. This is the greatest feature of the current U.S. trade policy.

Tariffs are becoming a permanent tool of governance rather than a temporary negotiation card.

Japan's "12.5%" is not a simple addition

There is also some misunderstanding about the 12.5% applied to Japan.

The current system does not add a flat 12.5% on top of existing tariffs for all Japanese products. In principle, it adjusts so that the total tax rate, combining the general U.S. tariff rate and the additional tariff, becomes 12.5%.

For example, if a product originally has a general tariff rate of 2.5%, the additional portion would be 10%, making a total of 12.5%. For products that already have a general tariff rate of 12.5% or more, the additional tariff may be zero.

Moreover, items such as steel, aluminum, and automobiles, which are subject to other trade law measures, are excluded from this tariff. For Japanese cars, there is a separate 15% tariff framework based on the 2025 U.S.-Japan agreement, so the 12.5% is not simply added on top of that.

Nevertheless, the impact on Japanese companies cannot be considered light.

Japan's exports to the U.S. are not composed solely of automobiles. A wide range of products, including industrial machinery, precision instruments, electronic components, chemical products, tools, medical-related products, and household goods, are supplied to the U.S. market. Particularly for medium and small enterprises, if U.S. importers demand price cuts or cost-sharing, they may not have the negotiating power to refuse.

Formally, U.S. importers pay the tariffs. However, in reality, it combines price reductions by exporting companies, increased procurement costs for U.S. companies, and passing on to consumer prices.

Just because Japanese companies do not directly pay the tariffs does not mean they are exempt from the burden.

Doubts about the explanation of "forced labor measures"

Forced labor is not an issue that should be taken lightly.

In international supply chains, there are serious human rights issues centered around agriculture, textiles, mining, fisheries, and electronics, such as restrictions on worker movement, confiscation of identification, debt bondage, and child labor. There is likely little disagreement on the need to require companies to verify their supply sources and stop the distribution of goods dependent on forced labor.

The problem is whether the current tariffs are a suitable system for that purpose.

The U.S. explains that it applies relatively low tax rates to countries that have introduced systems to ban imports of forced labor goods and imposes high tax rates on countries deemed insufficient. However, with countries like Japan, Switzerland, and Australia, which have significantly different labor environments and legal systems, being placed in similar categories, there are voices questioning the transparency of the judgment criteria.

Instead of individually stopping companies or products confirmed to be related to forced labor, the system imposes tariffs on a wide range of products by country, causing both problematic businesses and companies with proper human rights management to bear the burden.

Furthermore, the revenue from the tariffs is not directly used for the relief of affected workers or strengthening audit systems. There is also no clear objective achievement standard for what improvements would lead to the removal of the tariffs.

Therefore, overseas trade experts have suggested that it may be a legal detour to revive tariffs invalidated by the courts, rather than a human rights policy.

If the purpose is human rights protection, what is needed is supply chain tracking, import bans, information disclosure requirements for companies, victim relief, and cooperation with international organizations. Broad tariffs do not fully align with any of these.

The U.S. counters Google's fines with tariffs

It should not be overlooked that tariffs are being used not only for trade issues but also as political pressure regarding digital regulations.

In July 2026, the European Commission imposed a total fine of 890 million euros on Google for favoring its own services in search results and app stores. The EU explained that this measure was to curb market dominance by giant digital companies and ensure fair competition conditions.

In response, President Trump reacted by claiming that U.S. companies were being unfairly attacked and warned that the EU would pay a high price.

What is happening here is not just a dispute between Google and the EU.

The EU is trying to enforce European competition laws and digital regulations on companies operating within its borders, regardless of nationality. Meanwhile, the U.S. administration increasingly views companies like Google, Apple, Meta, and Amazon as strategic assets of the U.S. and perceives foreign regulations as attacks on U.S. companies.

As a result, competition policy in the digital market is linked with tariff negotiations.

This is not irrelevant for Japan either. If Japan strengthens regulations on giant IT companies or introduces its own rules regarding app markets, search, advertising, and artificial intelligence, it could be recognized as discrimination against U.S. companies and become a target of trade pressure.

The application of competition law should be contested through judicial procedures and consultations between regulatory authorities. If tariffs are introduced there, a structure emerges where "regulating U.S. companies results in retaliation against export industries."

Tariffs are beginning to transform from a means of industrial protection to a tool for changing domestic laws and regulatory policies of other countries.

An unusual logic of tariffs even on wildfire smoke

The response to Canada has caused the greatest confusion in this series of actions.

In the summer of 2026, numerous wildfires occurred in Canada, and smoke drifted across the border into the northeastern and midwestern United States. Air pollution warnings were issued, and the impact spread to civilian life.

President Trump criticized Canada for not adequately managing forest fires and suggested adding the costs borne by the U.S. due to the smoke to tariffs on Canadian products. He also posted a composite image on social media suggesting the placement of a giant air purification facility at the U.S.-Canada border.

Canada already has a 50% tariff on some products for other reasons, such as automobiles, alcoholic beverages, and dairy products. The additional pressure based on wildfire smoke has been added to this tense situation.

However, wildfire smoke cannot be stopped at a country's customs. It is a cross-border environmental issue involving multiple factors such as drought, high temperatures, lightning, forest management, and climate change.

There are years when smoke from Canadian forests drifts into the U.S., and there are also times when smoke from U.S. wildfires drifts into Canada. There is a history of firefighters and aircraft from both countries cooperating in firefighting activities across the border.

While there is meaning in internationally discussing the cost burden of environmental damage, there is little necessity for that method to be specific tariffs on imports. Imposing tariffs on automobiles or dairy products does not necessarily increase forest fire prevention facilities.

Solving environmental issues requires joint firefighting systems, satellite monitoring, forest maintenance, investment in firefighting aircraft, and greenhouse gas reduction. While tariffs can express political anger, they cannot reduce smoke.

Confusion, irony, and "who pays the tax" on social media

Multiple reactions to the current tariffs have been observed on social media.

One prominent point in public posts is the observation that "it is not foreign governments but U.S. importers who pay the tariffs first."

Tariffs are sometimes described as an invoice to the counterpart country, but it is the importers within the U.S. who pay at customs. If companies do not absorb the costs, they are passed on to retail prices or component prices. Since U.S. consumers and manufacturers also bear the burden, tariffs are not a weapon that only harms the counterpart country.

The second point is the question of applying the 12.5% standard to countries like Japan and Switzerland while citing forced labor as the reason. Accounts dealing with trade and supply chains have suggested that the tax rates may have been set according to other trade goals rather than the human rights situation in each country.

On the other hand, posts confirming the fact that "the tariff on Japan is not simply an additional 12.5% on existing rates, but a mechanism to make the total 12.5%" have also spread. They caution against interpreting headlines as meaning that the tax rate on Japanese products will suddenly exceed 25%.

Regarding the Canadian wildfires, there was stronger irony and anger.

On Canadian-related forums, there were reactions questioning whether tariffs would also be charged for smoke from past U.S. fires and how the contributions of firefighters who conducted cross-border firefighting would be treated. There was also discomfort expressed about using the issue as a trade sanction material amid wildfire victims and firefighting personnel.

However, not all reactions were critical.

In posts supporting protectionism, there were arguments that labor exploitation behind cheap imports should not be left unaddressed and that it is reasonable to demand institutional reform from countries as a condition for access to the U.S. market.

What emerges from social media reactions is not opposition to forced labor measures themselves. It is the question of whether there is a convincing policy connection between human rights issues and broad tariffs.

For Japanese companies, the "frequency of changes" is more troubling than the tax rate

For Japanese companies, the decline in predictability of the system is as serious as the figure of 12.5% itself.

In manufacturing, it takes several months to years from product development, parts procurement, production, transportation, to sales. The assumptions for sales prices and exchange rates must also be decided in advance.

However, if tariff rates and target items change in a short period, companies cannot calculate costs. There is a possibility that the system changes while goods are being transported by ship, and products that were supposed to be profitable at the time of the contract may end up in the red upon arrival.

Large companies can respond by expanding production within the U.S., changing export destinations, reorganizing parts procurement, and revising prices. However, small and medium-sized enterprises supplying parts to specific companies do not have that leeway.

It is not a simple matter of avoiding tariffs by producing within the U.S. Even if factories are relocated, if equipment, materials, and electronic components are imported from overseas, they are affected by tariffs. U.S. labor costs, construction costs, electricity costs, and logistics costs must also be considered.

Furthermore, if the administration changes, policies may also change. If tariffs are abolished a few years after making a huge investment to build a U.S. factory, the investment decision itself becomes disadvantageous.

What companies need most is not necessarily zero tariffs. It is stable rules that can be calculated several years ahead.

Is it enough for Japan to seek "exceptional treatment"?

What the Japanese government should first do is seek the abolition or exemption of tariffs through consultations with the U.S. It is also necessary to confirm specific grounds for the blanket assessment that Japanese companies are involved in forced labor.

However, focusing policy on having Japan alone treated as an exception is dangerous.

If the U.S. continues to link tariffs with security, drugs, immigration, human rights, digital regulation, and environmental issues, even if one negotiation is concluded, there remains the possibility of new tariffs being introduced for other reasons.

Japan needs at least three responses.

The first is to strengthen the human rights verification system in the supply chain.

In Japan, a system to comprehensively stop goods suspected of being produced by forced labor at customs, similar to that in the U.S., is not established. Relying solely on voluntary investigations by companies leaves room for overseas criticism that measures are insufficient.

By clarifying the standards for import bans, corporate accountability, disclosure of procurement sources, and victim relief mechanisms, it contributes to human rights protection and weakens the pretext for the U.S. to target Japan for sanctions.

The second is the diversification of export markets.

The U.S. will continue to be an extremely important market. However, the higher the dependency on a single market, the more its policy changes affect the management of Japanese companies.

It is necessary to expand sales networks to Europe, Southeast Asia, India, the Middle East, and Latin America, and utilize agreements such as the Trans-Pacific Partnership, the Japan-EU Economic Partnership Agreement, and the Regional Comprehensive Economic Partnership in real business.

The third is collaboration with countries facing the same issues.

If Japan, the EU, Canada, Australia, South Korea, and others negotiate individually with the U.S., the counterpart can present different conditions for each country and extract concessions. It is important for countries to form a common stance on the principle of not arbitrarily linking human rights, digital regulation, and environmental issues with tariffs.

Maintaining an alliance relationship with the U.S. is not the same as accepting all U.S. trade measures
