Foreign Company Loses a Major Contract Due to a Turkish Supplier’s Breach: Can Consequential Losses Be Recovered? 2026 Updated Guide

A Turkish supplier’s breach causes a foreign company to lose a major customer or contract. Learn when lost profits and consequential losses may be recovered under Turkish law and how damages can be proven.

A Turkish supplier’s breach can cause losses far beyond the value of the defective or undelivered goods. A foreign buyer may lose a major customer, miss a project deadline, face contractual penalties, suffer production interruption or lose the profit expected from an important resale contract. The central question is whether these consequential losses and lost profits can be recovered from the Turkish supplier. Under Turkish contract law, recovery may potentially extend beyond the immediate value of the failed performance. However, the claimant must establish the breach, legally recoverable damage, adequate causal connection and the amount of loss. The contract’s limitation-of-liability provisions and the circumstances surrounding the supplier’s fault can also materially affect the outcome.

What Is a Consequential Loss?

Consequential loss generally refers to financial damage arising as a further consequence of contractual breach rather than merely the immediate difference between promised and delivered performance.

For example, a Turkish manufacturer fails to deliver components to a foreign buyer. The immediate loss may concern replacement costs. The wider consequence may be that the foreign company cannot deliver finished products to its own customer and loses a valuable contract.

Can a Foreign Company Claim More Than the Purchase Price?

Potentially, yes. A damages claim is not necessarily limited to reimbursement of the amount paid to the supplier.

Depending on the facts, recoverable losses may potentially include replacement procurement costs, additional transport expenses, contractual penalties paid to customers, production interruption losses and lost profits.

Each category must be analyzed separately.

The Supplier Must First Have Breached the Contract

The starting point is establishing contractual non-performance or defective performance.

Typical breaches include late delivery, complete non-delivery, defective goods, incorrect specifications, insufficient quantities, failure to satisfy quality requirements or delivery of goods that cannot lawfully be used for the agreed commercial purpose.

Preserve the Supply Contract

The foreign company should immediately preserve the executed agreement, purchase orders, specifications, amendments, delivery schedules, correspondence and general terms.

The precise obligation allegedly breached must be established before damages are calculated.

Lost Customer Contract Claims Require a Clear Causal Link

It is not enough to show that the supplier breached one contract and that the foreign company later lost another.

The claimant should demonstrate how the Turkish supplier’s breach caused the loss of the downstream contract.

Build a Detailed Timeline

A strong damages file should show when the Turkish supplier was required to perform, when the breach occurred, what warnings were given, when the foreign company was required to perform toward its customer and why alternative performance was not reasonably available.

Chronology can become central to causation.

Was the Supplier Aware of the Downstream Contract?

This can be an important factual issue.

If the supplier knew that the goods were being purchased specifically for a major customer contract or project, the foreign company’s argument concerning resulting commercial losses may become stronger.

Preserve correspondence mentioning the customer, project, deadlines or consequences of delay.

Confidentiality Does Not Prevent Evidence Preservation

A foreign company may be reluctant to disclose its downstream customer contract because of confidentiality obligations.

The agreement should nevertheless be preserved. Appropriate procedural confidentiality measures can be considered if litigation or arbitration requires disclosure.

Lost Profits Can Potentially Be Claimed

A claimant may seek the profit it would have earned had the supplier performed correctly, subject to the applicable legal requirements and proof.

The claim should be based on realistic commercial evidence rather than an optimistic projection.

Revenue Is Not the Same as Lost Profit

This distinction is critical.

If a lost contract had a value of EUR 5 million, the foreign company cannot automatically claim EUR 5 million as lost profit. Costs that would have been incurred to perform the downstream contract generally need to be considered when determining the actual economic loss.

How Can Lost Profit Be Proven?

Useful evidence may include the terminated customer contract, historical profit margins, previous comparable projects, purchase orders, pricing calculations, accounting records, budgets, production costs and customer correspondence.

An expert financial analysis may be necessary for substantial claims.

A Signed Downstream Contract Is Strong Evidence

Where the foreign company already had a binding contract with its customer, proving the existence of the lost commercial opportunity is generally easier than where the company merely expected to win future business.

Preserve the complete contract and termination correspondence.

What If the Customer Had Only Issued a Purchase Order?

A purchase order may still provide important evidence depending on the contractual structure.

The parties’ previous course of dealing, acceptance procedures and surrounding communications should also be examined.

What About a Lost Tender?

Claims involving an anticipated tender award are more difficult because the claimant may need to establish that the commercial opportunity was sufficiently concrete.

A mere hope of obtaining future business should be distinguished from an already secured contract.

Customer Termination Letters Are Important

If the downstream customer terminated because of the Turkish supplier’s delay or defective performance, obtain a written explanation.

A termination letter expressly connecting the cancellation with missed delivery can become powerful causation evidence.

Contractual Penalties Paid to the Customer

The foreign company may have been required to pay liquidated damages, delay penalties or another contractual amount to its own customer.

Whether those amounts can be recovered from the Turkish supplier depends on the contract, causation and applicable damages rules.

Production Interruption Losses

A supplier’s breach can stop a production line where critical components are unavailable.

The claimant should document shutdown dates, production capacity, missed output, labor costs and efforts made to obtain alternative components.

Replacement Purchases Should Be Documented

If substitute goods were purchased at a higher price, preserve competing quotations, replacement invoices, freight costs and urgent procurement expenses.

These losses may be easier to quantify than speculative future profits.

The Duty to Mitigate Loss Is Important

A claimant should take reasonable steps to prevent avoidable damage from increasing.

If substitute goods were reasonably available but the buyer took no action for several months, the supplier may argue that part of the loss could have been avoided.

Document Mitigation Attempts

Preserve communications with alternative suppliers, emergency freight providers and customers.

Even unsuccessful mitigation efforts can demonstrate that the foreign company acted reasonably.

Expensive Emergency Procurement May Still Be Reasonable

A buyer should not necessarily be expected to wait for the cheapest replacement if delay would cause substantially greater losses.

The commercial circumstances at the time of the decision should be documented.

Can Loss of Future Business Be Claimed?

Potentially, but future-business claims require particularly careful proof.

The claimant should distinguish between profits arising from an existing contract and speculative assumptions that a customer would have continued placing orders indefinitely.

Long-Term Customer Relationships Can Be Relevant

Historical purchase volumes, framework agreements, renewal patterns and customer correspondence may help establish the likelihood of continuing business.

However, each future-loss claim should remain economically supportable.

Damage to Commercial Reputation

A supplier failure may damage the foreign buyer’s reputation with an important customer.

Although commercial consequences can be significant, converting reputational harm into a specific recoverable financial amount may require substantial evidence.

Review Limitation-of-Liability Clauses

International supply contracts frequently contain provisions excluding consequential damages, lost profits or indirect losses.

These clauses can become one of the most important issues in the dispute.

Is a Consequential-Loss Exclusion Always Enforceable?

Not necessarily in every circumstance. The validity and scope of contractual limitations should be examined under the law governing the agreement and mandatory rules potentially applicable to the supplier’s conduct.

The precise wording matters significantly.

Liability Caps Must Also Be Reviewed

A contract may cap damages at the purchase price, annual contract value or another amount.

The claimant should determine whether the cap covers all claims, only particular breaches or excludes certain categories of misconduct.

Gross Fault Can Become Particularly Important

Turkish mandatory contract-law principles can restrict advance attempts to exclude liability in circumstances involving serious fault. Accordingly, the supplier’s degree of fault may materially affect the effectiveness of certain contractual limitations.

This should be examined carefully rather than assuming that every liability cap automatically controls the dispute.

Warranty Clauses Should Be Read Together With Liability Provisions

A contract may contain detailed warranties concerning quality, specifications, regulatory compliance and delivery while separately restricting available damages.

The agreement should be interpreted as a whole.

Notice Requirements Can Affect the Claim

International supply agreements frequently require the buyer to notify defects or claims within specified periods.

The foreign company should send appropriate notices promptly and preserve proof of delivery.

Do Not Wait Until All Losses Are Known

If losses continue developing, the buyer should still protect its contractual and procedural position.

Initial notice can identify the breach while reserving rights concerning damages that are still being quantified.

Preserve Emails and Messaging Records

Commercial disputes are often determined by communications showing what the supplier knew and promised.

Preserve emails, messaging records, meeting minutes and delivery updates concerning deadlines and the downstream customer’s requirements.

Supplier Admissions Can Be Important

Statements acknowledging production problems, quality defects or inability to meet delivery dates should be preserved.

Do not rely solely on later summaries of telephone conversations.

Independent Technical Evidence May Be Needed

If the supplier argues that the goods were compliant, technical expert evidence may be necessary before consequential damages can even be addressed.

Preserve defective goods and samples where possible.

Do Not Destroy Defective Products Prematurely

If products must be scrapped, repaired or returned, document their condition thoroughly first.

Photographs, inspection reports and samples may become essential in subsequent proceedings.

Foreign Currency Losses Should Be Calculated Carefully

Cross-border supply disputes may involve payments and losses in different currencies.

The applicable contract terms and legal framework should be reviewed when determining the currency and calculation of the claim.

Interest Can Be a Significant Part of the Dispute

Large commercial damages claims may remain unresolved for years.

The applicable interest rules, contractual provisions and date from which interest can be claimed should therefore be analyzed at an early stage.

Governing Law Must Be Checked

Do not assume Turkish law automatically governs merely because the supplier is located in Turkey.

The contract may contain a governing-law clause. In international sales, applicable conflict-of-laws rules and potentially applicable international sales regimes should also be examined.

Check the Dispute Resolution Clause

The contract may require proceedings before Turkish courts, foreign courts or arbitration.

Before commencing proceedings, determine the agreed forum and whether pre-litigation negotiation or notice procedures exist.

Arbitration Clauses Can Be Particularly Important

International supply contracts frequently refer disputes to arbitration.

The claimant should comply precisely with the arbitration clause, including institutional rules, seat and notice requirements.

Evidence Located in Turkey Should Be Identified

The Turkish supplier may hold production records, quality-control documents, inventory information and internal correspondence relevant to the breach.

The litigation or arbitration strategy should account for evidence controlled by the opposing party.

Interim Measures May Be Necessary

If there is a serious risk that assets will disappear or enforcement will become difficult, available interim remedies should be evaluated promptly.

The applicable requirements depend on the forum and circumstances.

Can the Turkish Supplier Argue Force Majeure?

Yes. Suppliers may rely on force majeure, hardship, raw-material shortages, transport disruption or other contractual defenses.

The existence of a difficult commercial situation does not automatically establish a valid force-majeure defense.

Examine the Force-Majeure Clause

Check whether the event falls within the contractual definition, whether timely notice was given and whether the event genuinely prevented performance.

The supplier’s mitigation efforts may also be relevant.

Ordinary Commercial Difficulty Is Not Automatically Force Majeure

Increased costs or reduced profitability should not automatically be equated with impossibility of performance.

The contractual language and factual circumstances should be examined carefully.

What If Both Parties Contributed to the Loss?

The supplier may argue that the foreign buyer caused or increased the damage through late specifications, delayed approvals or failure to mitigate.

Preserve evidence demonstrating the buyer’s own compliance with contractual obligations.

Expert Financial Evidence Can Be Essential

For multimillion-euro consequential-loss claims, a financial expert may need to reconstruct the counterfactual position: what would probably have happened if the supplier had performed correctly.

The analysis should separate actual losses from hypothetical or duplicated claims.

Avoid Double Recovery

A claimant should not seek the same loss twice under different labels.

Replacement costs, lost profits and customer penalties should be analyzed carefully to prevent overlap.

Review Insurance Coverage

The foreign company may have business interruption, trade credit, cargo or another relevant policy.

Insurance recovery and supplier liability should be coordinated to avoid procedural problems and preserve subrogation rights.

Consider Claims Against Other Responsible Parties

The Turkish supplier may not be the only party responsible.

Depending on the facts, carriers, subcontractors, testing companies or other parties may have contributed to the loss.

Settlement Should Be Based on a Proper Damages Model

Before negotiating, calculate immediate losses, customer penalties, replacement procurement, lost profits, mitigation expenses and interest separately.

A documented damages model provides a stronger basis for settlement than a single unsupported lump-sum demand.

Immediate Action Plan

When a foreign company loses a major contract because of a Turkish supplier’s breach, it should immediately preserve the supply and downstream contracts, issue required notices, document the supplier’s breach, obtain written evidence explaining the customer’s cancellation, calculate replacement and mitigation costs, preserve accounting records supporting lost profits, review liability caps and consequential-loss exclusions, analyze governing law and dispute resolution provisions and evaluate interim remedies where recovery is at risk.

Frequently Asked Questions

Can a foreign company claim lost profits from a Turkish supplier?

Potentially, provided the applicable legal requirements concerning breach, damage and causation are satisfied and the loss can be established with sufficient evidence.

Can the entire value of the lost customer contract be claimed?

Not automatically. Contract revenue and lost profit are different. Costs that would have been incurred in performing the lost contract may need to be deducted.

Can customer penalties be recovered from the supplier?

Potentially, if they were caused by the supplier’s breach and satisfy the applicable contractual and damages requirements.

What if the supply contract excludes consequential damages?

The wording and validity of the exclusion must be analyzed under the governing law. The supplier’s degree of fault and mandatory legal rules can also become important.

Does the supplier need to know about the downstream contract?

Supplier knowledge can be highly relevant to the factual and legal assessment of consequential losses. Evidence showing that the supplier knew about the project and deadlines should be preserved.

Can future lost business be claimed?

Potentially, but the more speculative the future business, the more difficult the evidentiary burden generally becomes.

Must the foreign buyer try to find another supplier?

Reasonable mitigation efforts are important. The buyer should document attempts to obtain substitute performance.

What evidence is strongest for lost-profit claims?

Signed customer contracts, termination correspondence, historical margins, accounting records, purchase orders and reliable expert financial calculations can be particularly important.

Can the foreign company sue in Turkey?

Possibly, but jurisdiction depends on the contract, applicable procedural rules and any arbitration or jurisdiction clause.

What should the foreign company do first?

Preserve both sides of the commercial chain. The strongest consequential-loss case connects the Turkish supplier’s specific breach directly to the downstream customer’s termination and supports the resulting financial loss with contracts, correspondence, accounting evidence and a credible damages calculation.
