Your Supplier Contract Was Written for a Different World
You signed the deal when pricing felt solid, the duty rate was predictable, and the phrase "force majeure" meant hurricanes and pandemics — not a presidential proclamation issued on a Monday morning. That world is gone. Tariffs have become a volatile business reality, with rates swinging dramatically and threatening to turn profitable contracts into losses overnight, and the average applied tariff rate on goods entering the United States now sits near its highest level in roughly eighty years. For importers and supply chain managers, the contract sitting in your filing cabinet may be your single largest unmanaged risk.
Why Tariffs Keep Catching Contracts Off Guard
The velocity of change is the core problem. Tariffs went up, got struck down by the Supreme Court, got refunded, and then came right back under different legal authority. The administration's willingness to test new trade authorities makes tariff policy harder for businesses, investors, and foreign governments to handicap — it is hard to know which tariffs will survive court challenges, and over what time horizon there may be any resolution, but even if individual tariffs are delayed or struck down, the threat alone forces companies to plan for higher costs.
The most recent example is illustrative. On July 20, 2026, the White House signed three proclamations invoking Section 338 of the Tariff Act of 1930, imposing an additional 50% tariff on a range of Canadian goods, effective August 19, 2026, covering the named categories of motor vehicles, alcoholic beverages, and dairy. Scroll past the headlines, however, and the list broadens fast — wine, hockey sticks, cement, plywood, furniture, fishing rods, seeds, clothing, swimming pools — with total exposure placed at nearly $20 billion, about 5.2% of all goods the U.S. imported from Canada in 2025. Businesses that assumed USMCA compliance would shield them were caught off guard: covered goods cannot claim preferential treatment under USMCA mechanisms. If your existing supply contracts did not anticipate that possibility, the duty burden lands on whichever party the contract left exposed.
The Force Majeure Trap
The first place most importers and buyers reach when tariff costs spike is the force majeure clause. It is almost always the wrong move. Many business owners instinctively reach for force majeure clauses when tariff costs spike, only to discover these provisions rarely cover increased expenses. Force majeure provisions are construed narrowly — and whether a tariff constitutes a force majeure event will depend on the specific language of the contract.
In the absence of a force majeure clause, parties may invoke the doctrine of impossibility or impracticability, under which contractual obligations may be excused when an unforeseen event prevents performance — but mere increases in difficulty or cost, such as rising tariff expenses, typically do not constitute impracticability, making these doctrines unlikely to assist. The practical lesson: a standard, off-the-shelf force majeure clause was written to excuse non-performance, not to redistribute a cost increase. Tariffs almost never make performance impossible — they just make it more expensive. That is a fundamentally different legal problem.
The Clauses That Actually Work
Three contractual tools give importers and their trading partners a genuine path through tariff volatility.
Tariff-Specific Price Escalation Clauses
Many long-term or volume-based contracts include price adjustment or escalation provisions that enable the supplier to revise pricing if the cost of key inputs rises above a defined threshold — and to be effective in the current climate, these clauses must include language covering tariffs, customs duties, and government-imposed fees, not just general market indices, so that when triggered, the supplier can raise prices during the contract term without risking a breach. A well-drafted clause can allow a price adjustment if a newly imposed or increased tariff raises the landed cost of a specified component by more than an agreed percentage, keeping the deal alive and sharing the pain rather than forcing an all-or-nothing fight.
Tariff Allocation and Pass-Through Provisions
Rather than absorbing tariff swings yourself, a tariff allocation provision states plainly which party is responsible for new or increased duties, and how those costs flow through the price. This is inherently a negotiation — buyers push one way, sellers the other — but having an explicit answer in the contract is vastly preferable to silence. Silence defaults to whoever the law says bears the import duty, which is almost always the importer of record, and that may not be the party with the leverage to absorb it.
Mutual Review and Renegotiation Triggers
Standard force majeure clauses often do not adequately address tariff changes, and a stronger approach includes explicitly listing significant tariff increases as qualifying events, defining what constitutes significant, and building in graduated response options based on severity rather than simple termination. Beyond that, the clause should clearly define the events that trigger the pass-through or relief, such as the imposition of new tariffs or changes in existing tariffs that impact the cost of imported materials, and should also outline whether any potential reductions in tariffs will be shared back with the buyer and how changes will be calculated and quantified.
How to Audit Your Existing Contracts Right Now
With tariffs in motion and the August 2026 effective dates already approaching, a contract audit is not a future-quarter project — it is a today task. Whether you are drafting new agreements or reviewing existing ones, run the audit on any contract that touches imported goods or fixed pricing: read each force majeure clause for the words tariffs, duties, trade restrictions, and change in law; confirm whether your price terms are truly fixed or allow adjustment; check who bears new or increased duties under the current language; verify the notice and mitigation steps required before invoking any relief clause; review your Harmonized Tariff Schedule classifications for accuracy; and map which inputs come from high-tariff countries and whether alternatives exist.
Suppliers and sellers must also be prepared to provide documentation demonstrating the increased costs directly resulting from new tariffs — that may include revised customs declarations, shipping invoices, or supplier quotes. This documentation requirement works both ways: as an importer, you should ask your suppliers to provide this evidence before agreeing to any price adjustment, and as a buyer you should build the documentation requirement into the contract language.
The Bigger Picture: Contracts as a Strategic Tool
The companies managing tariff exposure best are not waiting for policy certainty before acting on their contracts. The most common tariff mitigation strategy involves changing sourcing patterns (cited by 65% of respondents in industry surveys), followed by renegotiating supplier contracts (57%), and nearshoring or moving manufacturing back to the U.S. (51%). Contract renegotiation — the second most-used strategy — is only possible when you know what your existing agreements actually say.
39% of organizations now report they are either absorbing or considering absorbing tariff costs rather than passing them to customers, up from just 13% the previous year. That margin compression is not inevitable; in many cases it is the direct result of contracts that were never designed to allocate tariff risk in the first place. Tariffs remain a central feature of global trade dynamics in 2026, with businesses increasingly treating them as a permanent element of supply-chain strategy rather than a temporary disruption. Your contracts should reflect that reality.
For manufacturers and supply chain professionals, the imperative remains unchanged: supply chains must be designed not just to survive today's tariffs, but to adapt to the next wave of trade policy disruption. A well-structured commercial agreement is one of the most durable forms of that protection.
How ASR Can Help
At ASR WorldWide Express, we work with importers every day who are trying to make sense of a duty environment that changes faster than most contracts were written to handle. While contract drafting is the domain of your legal counsel, the logistics and customs clearance side of the equation is ours. Our team — working alongside licensed customs broker partners — helps importers understand what they are actually paying at the border, how classification decisions affect duty exposure, and what documentation your supply chain needs to support price adjustment claims. A clearer picture of your true landed cost is the starting point for any meaningful contract conversation.
