– Buffalo Springfield, “For What It’s Worth” (1966)

One can be forgiven for losing track of the volley and folly of the present trade war between the United States and Canada. These developments have created significant uncertainty and complexity for the private aviation industry in the US market in particular, especially for transactions involving Canadian-manufactured aircraft or aircraft parts, or aircraft imported from or exported to Canada. Of critical importance: this article is current as of Sunday March 9th, 2025. That is worth noting because the situation is fluid – fitting, since fluid too tends to flow downhill.
The complexities of the present situation are further compounded by the need to navigate the USMCA compliance and the potential for reciprocal tariffs. The impact of tariffs on all manner of commercial contracts in the industry can be profound, affecting pricing, risk allocation, and contract performance. In this client alert, we will highlight some of the key “Whipsawing Trade Frameworks” considerations that private aviation industry participants should be aware of at this time.
The Trump Administration has recently imposed a 25% tariff on certain Canadian products, which for the moment does include both aircraft and aircraft engines, due to a political and trade dispute – the coherent articulation of which is beyond the scope of client alert, thankfully. This tariff was temporarily paused in February 2025 until March 4th, 2025. In March, this pause was further extended until April 2nd 2025, but only for USMCA-compliant goods. Since this is an unfolding situation, there are no guarantees that this pause will be further extended in April. Additionally, there is a possibility of reciprocal tariffs on other products from Canada and other countries with different tariff rates than the US. Reciprocal tariffs are designed to level the playing field by imposing equivalent tariffs on imports from countries that have higher tariffs on US goods. This approach aims to encourage fair trade practices and reduce trade imbalances. The potential for these tariffs has created a significant amount of uncertainty in many markets, including private aviation, as stakeholders are unsure how long the pauses will last and what the nature and extent of its long-term implications will be.
One of the main challenges for importing Canadian aircraft or aircraft engines into the US is to obtain a certification that the goods qualify for duty-free treatment under the US-Mexico-Canada Agreement (USMCA). The USMCA is a free trade agreement that allows for preferential tariff treatment for goods that originate in the US, Canada, or Mexico, or that undergo a substantial transformation or a tariff shift in one of these countries. This certification process is crucial as it is currently the only way to avoid the 25% tariff on Canadian aircraft or aircraft engines, given that the tariff suspension is contingent on the goods being eligible for USMCA treatment.
However, the aviation industry has not historically relied on the USMCA to claim duty-free treatment, as most aircraft and aircraft engines were already duty-free under the World Trade Organization Agreement on Trade in Civil Aircraft. Therefore, the industry does not have a well-established process or documentation to certify the origin of the goods under the USMCA. This lack of established processes has led to significant confusion and delays, as stakeholders scramble to understand and comply with the new requirements.
The USMCA certification can be made by the manufacturer, the exporter, or the importer, based on sufficient knowledge or information that the goods meet the origin criteria. The certification must include certain data elements, such as the description, tariff classification, and origin criteria of the goods, and must be provided to the US Customs and Border Protection (CBP) upon request. The certification does not have to follow a prescribed format, but it must be in writing, either in paper or electronic form. This flexibility in format, however, does not reduce the complexity of gathering the necessary information and ensuring its accuracy.
As mentioned above, the USMCA certification is currently the only way to avoid the 25% tariff on Canadian aircraft or aircraft engines. Therefore, it is crucial to obtain the certification from the manufacturer or the seller, or to have sufficient evidence to make the certification yourself, before importing the goods into the US. Otherwise, you may face significant delays, costs, and risks at the port of entry. Additionally, the certification process may require coordination with multiple parties, including manufacturers, exporters, and customs brokers, to ensure compliance and avoid potential penalties.
The USMCA certification may also be required in the future, depending on whether the tariff suspension is extended or lifted, and whether the US imposes reciprocal tariffs on other products. Therefore, it is advisable to prepare for this scenario and to review your existing and future contracts to ensure that they address the USMCA certification issue. This preparation should include updating force majeure clauses, material adverse change provisions, and other relevant contract terms to account for the potential impact of tariffs and certification requirements.
In addition to the USMCA certification, there are other issues and considerations that you should be aware of if you are involved in transactions involving Canadian aircraft or aircraft parts, or aircraft imported from or exported to Canada. These issues include understanding the nuances of the tariff application, the impact on supply chains, and the potential for future regulatory changes. Some of these are:
In conclusion: WTF, indeed. The 25% tariff on Canadian products, including aircraft and aircraft engines, and the potential reciprocal tariffs on other products, have created significant uncertainty and complexity for the private aviation industry, especially in the US market. The USMCA certification is a temporary lifeline to avoid the tariff, but it requires careful preparation and documentation. There are also other issues and considerations that you should be aware of if you are involved in transactions involving Canadian aircraft or aircraft parts, or aircraft imported from Canada. We recommend that you consult with a customs broker and an attorney to determine the best course of action for your situation, and to ensure compliance with the applicable laws and regulations. Additionally, staying informed about potential changes in tariff policies and preparing for various scenarios will be crucial in navigating this complex and constantly changing landscape. This is perhaps the best advice to offer industry participants at this moment, and it is free of charge and tariffs.
