Introduction
Tariffs have long been a key instrument in national trade policy, but in recent years, they have become volatile, often unpredictable disruptors of global commerce. Businesses that once operated under stable international supply agreements have found themselves grappling with sudden cost spikes, regulatory complexity, and broken contractual expectations. These pressures have frequently led to renegotiations, terminations, and legal disputes.
This article explores real-world case studies in which tariffs directly triggered contract termination or necessitated renegotiation. These cases span multiple industries—technology, agriculture, manufacturing, pharmaceuticals—and offer practical insights into how businesses have navigated the risks and fallout of tariff shocks. We analyze the legal frameworks invoked, the outcomes reached, and the strategic takeaways for commercial actors operating in the modern trade environment.
1. Tech Hardware Supply Chain: U.S.–China Trade War Fallout
Background
A California-based electronics firm had a multi-year supply agreement with a Chinese manufacturer for printed circuit boards (PCBs). The pricing model assumed a stable cost of production and was set in USD.
Triggering Event
In 2018, the U.S. imposed 25% tariffs on Chinese-made PCBs. The cost of imports surged overnight, rendering the contract economically untenable for the buyer.
Contractual Provisions
- No force majeure clause specific to tariffs
- No price adjustment or hardship mechanism
- Fixed pricing for five years
Outcome
- The buyer issued a termination notice, citing commercial impracticability.
- The supplier sued in Hong Kong under ICC rules.
- Arbitration tribunal ruled in favor of the supplier, stating that tariff imposition, while burdensome, was foreseeable due to escalating geopolitical tensions at the time the contract was signed.
Key Takeaway
Tariff-induced hardship may not be sufficient to void fixed-price agreements unless the risk is expressly addressed in the contract.
2. Agricultural Commodities: Soybean Exports and Retaliatory Duties
Background
A South American soybean exporter had a contract to supply soybeans to a Chinese state-owned importer with deliveries over 18 months.
Triggering Event
China imposed retaliatory tariffs on U.S. and non-Chinese agricultural imports, including soybeans, during a tit-for-tat trade war in 2019.
Contractual Provisions
- Force majeure clause including “government-imposed restrictions”
- CIF Incoterm (Cost, Insurance, Freight)
- Price renegotiation clause for supply chain disruptions
Outcome
- The Chinese buyer invoked the force majeure clause and refused to accept shipments.
- The exporter initiated arbitration under the CIETAC rules.
- Tribunal accepted that the tariffs constituted a qualifying government restriction but noted that the renegotiation clause should have been triggered first.
- Partial award: parties were required to renegotiate pricing under revised tariff conditions rather than terminating.
Key Takeaway
Inclusion of both force majeure and renegotiation clauses can create ambiguity—courts or tribunals may prioritize commercial continuity through renegotiation.
3. Automotive Components: EU–Turkey Customs Conflict
Background
A German carmaker outsourced brake pad manufacturing to a Turkish supplier. The agreement fixed prices in EUR and required annual minimum volumes.
Triggering Event
Due to customs union disputes between Turkey and the EU, the EU imposed temporary safeguard duties on Turkish automotive parts.
Contractual Provisions
- No mention of tariffs or customs risk
- Termination allowed only for cause or insolvency
Outcome
- Turkish supplier requested renegotiation due to financial strain.
- German buyer refused, citing firm pricing terms.
- Supplier stopped delivering and invoked economic force majeure under Turkish law.
- Dispute was resolved in Istanbul arbitration: tribunal found in favor of the supplier and ordered contract renegotiation under hardship principles.
Key Takeaway
Where contracts lack tariff-related provisions, local legal doctrines (e.g., Turkish hardship laws) may allow contract rebalancing.
4. Consumer Goods: U.S. Importer and Southeast Asian Textile Manufacturer
Background
A U.S. retailer had a long-term supply agreement with a Vietnamese textile manufacturer. Pricing was pegged to raw material costs and indexed semi-annually.
Triggering Event
In 2020, the U.S. imposed tariffs on textiles from Vietnam due to concerns over trade imbalances and alleged currency manipulation.
Contractual Provisions
- Indexed pricing formula
- No force majeure or tariff clause
- Dispute resolution through New York courts
Outcome
- Retailer withheld payments and reduced orders.
- Manufacturer sued in New York state court.
- Court dismissed the retailer’s tariff defense, stating that U.S. tariffs were not unforeseeable in the current global environment.
- Judgment awarded full damages to the manufacturer.
Key Takeaway
Absent specific language, courts may treat tariffs as a normal business risk, particularly for buyers in politically active jurisdictions like the U.S.
5. Pharmaceuticals: Export Restrictions in India
Background
A European pharmaceutical distributor relied on Indian suppliers for active pharmaceutical ingredients (APIs).
Triggering Event
During the COVID-19 pandemic, India imposed export bans and tariffs on certain APIs to secure domestic supplies.
Contractual Provisions
- Force majeure clause including “governmental interventions”
- Arbitration under SIAC (Singapore International Arbitration Centre)
Outcome
- The Indian supplier invoked force majeure and canceled orders.
- The distributor initiated arbitration.
- SIAC tribunal sided with the supplier, noting that the export restrictions were both unforeseeable and absolute, making performance impossible.
Key Takeaway
Absolute bans or prohibitions are more likely to support a successful force majeure defense compared to general tariffs or duties.
6. Steel Industry: U.S. Section 232 Tariffs
Background
A Canadian steel manufacturer exported rolled steel to U.S. buyers under annual supply contracts.
Triggering Event
In 2018, the U.S. imposed 25% tariffs on steel imports from several countries under Section 232 of the Trade Expansion Act.
Contractual Provisions
- Governing law: New York
- Price adjustment clause for material cost changes
- No explicit provision for government tariffs
Outcome
- U.S. buyers refused to absorb increased prices.
- Supplier argued that price adjustment clause should cover tariff costs.
- New York court held that “material cost changes” did not include tariffs unless specifically stated.
- Supplier suffered losses and shifted to shorter contract terms moving forward.
Key Takeaway
Price adjustment clauses need to be drafted clearly to encompass external costs like tariffs—not just input costs.
7. Energy Sector: LNG Contracts Between Australia and China
Background
A Chinese state-owned energy company entered into a 20-year LNG supply contract with an Australian exporter.
Triggering Event
Amid political tensions, China imposed informal barriers, including delayed customs approvals and unofficial quotas, effectively functioning as non-tariff barriers.
Contractual Provisions
- Long-term fixed volume commitments
- Force majeure clause required formal written law or regulation
Outcome
- Chinese buyer delayed offtake and claimed logistical disruptions.
- Australian exporter initiated arbitration in Singapore.
- The tribunal concluded that informal delays did not constitute force majeure since they lacked formal regulatory backing.
Key Takeaway
Informal government actions are difficult to classify as force majeure—written laws or orders are usually required to excuse non-performance.
8. Electronics: Tariff Clause Successfully Enforced
Background
A U.S. consumer electronics brand had a supply agreement with a South Korean parts manufacturer.
Triggering Event
Unexpected tariffs were imposed on South Korean tech imports as part of a trade balancing initiative.
Contractual Provisions
- Explicit tariff clause stating that if tariffs exceeded 10%, both parties must renegotiate within 15 days
- Arbitration clause under LCIA rules
Outcome
- Tariffs rose to 18%
- Both parties met within the 15-day window and agreed to adjust pricing
- No arbitration was needed
Key Takeaway
Proactive tariff clauses with renegotiation triggers can prevent disputes and maintain commercial relationships.

Legal Doctrines Commonly Invoked in Tariff Disputes
- Force Majeure – especially when government action makes performance illegal or impossible.
- Hardship – applicable under civil law systems like France, Italy, and Turkey where significant changes in circumstances may lead to contract adjustment.
- Commercial Impracticability (UCC §2-615) – under U.S. law, a party may be excused if performance becomes impracticable due to unforeseen government actions.
- Frustration of Purpose – when a fundamental purpose of the contract is destroyed due to external events like tariffs.
Best Practices for Businesses
- Include clear clauses allocating tariff risk.
- Use price escalation or renegotiation clauses tied to specific thresholds.
- Define what qualifies as force majeure, including whether tariffs, export bans, or embargoes count.
- Choose arbitral institutions with trade and commercial expertise.
- Keep abreast of geopolitical trends that may signal policy shifts.
- Consider insurance or hedging instruments for tariff risk exposure.
Conclusion
Tariffs are no longer a peripheral concern in contract planning—they are central to risk management in international trade. As the case studies above show, companies that failed to plan for sudden tariff changes faced terminations, lawsuits, and broken partnerships. In contrast, those that incorporated flexibility, legal foresight, and renegotiation mechanisms navigated disruptions more successfully.
Going forward, businesses must treat tariff exposure as a dynamic legal and commercial risk. Building agile contracts, staying informed about geopolitical developments, and choosing neutral dispute resolution forums will be key to maintaining trade continuity in an unpredictable world.

FAQs on Revenue Assurance
Can tariffs qualify as force majeure?
Yes, but only if the contract's force majeure clause specifically includes tariffs or if the legal system recognizes tariffs as unforeseeable government actions that prevent performance.
Are parties required to renegotiate when tariffs make performance difficult?
Only if the contract includes a renegotiation or hardship clause. Otherwise, courts and arbitrators may expect parties to honor the original terms.
What should a tariff clause in a contract include?
It should define who bears the tariff risk, set thresholds for renegotiation, and specify remedies such as price adjustment or termination.
Are non-tariff barriers treated the same as tariffs in disputes?
Not always. Informal restrictions, like customs delays or quotas, may not qualify as force majeure unless codified in formal legal instruments.
Can parties simply walk away from a contract due to tariffs?
No, not without legal justification. Termination without a proper basis can lead to breach of contract claims.
How do courts interpret the foreseeability of tariffs?
Courts often consider the political climate at the time of contract signing. If tariffs were reasonably foreseeable, force majeure claims may fail.
Do Incoterms affect who pays tariffs?
Yes. For example, DDP (Delivered Duty Paid) makes the seller responsible for tariffs, while FOB or CIF may place the burden on the buyer.
What’s the role of arbitration in tariff disputes?
Arbitration offers a neutral and efficient forum for resolving international tariff disputes, especially when government-related policies are involved.
Can I use insurance to protect against tariff risks?
Yes, trade disruption insurance or political risk insurance can cover tariff-related losses, though such products may come at a premium.
How should I prepare for future tariff volatility?
Regularly update contract templates to include tariff clauses, monitor geopolitical developments, and maintain strong communication with trade partners.
