Foreign Buyer Rejects Turkish Goods for Quality Problems: CISG Rights and Deadlines (2026 Updated Guide)

A foreign buyer rejects goods supplied from Turkey because of quality defects. Learn how the CISG regulates conformity, inspection, notice of defects, repair, replacement, price reduction, avoidance, damages and critical deadlines.

When a foreign buyer purchases goods from a Turkish seller and later claims that the products are defective, below specification or otherwise unsuitable, the dispute may fall within the United Nations Convention on Contracts for the International Sale of Goods (CISG). For international sales contracts within its scope, the CISG can determine whether the goods conform to the contract, when the buyer must inspect them, how quickly defects must be notified, whether the buyer can reject the goods and what remedies may be claimed. A foreign buyer should not assume that discovering a quality problem automatically gives an unrestricted right to cancel the contract or return the entire shipment. The contractual specifications, nature of the defect, timing of inspection, notice given to the Turkish seller, seriousness of the non-conformity and possibility of cure can all become decisive.

When Does the CISG Apply to a Sale of Turkish Goods?

The CISG generally governs qualifying international sales of goods between parties whose places of business are in different states where the Convention’s application requirements are satisfied. The contract itself must also be examined because parties may exclude the CISG or modify the effect of its provisions.

The first step in a quality dispute is therefore to determine the governing law and whether the CISG applies.

Contract Terms Come First

The CISG does not replace the parties’ agreed product specifications. The sales contract, purchase order, technical specification, approved sample, drawings, quality protocol, certificates and correspondence should be examined together.

A product can be commercially usable and still be non-conforming if it does not satisfy an expressly agreed specification.

What Counts as Non-Conforming Goods?

Under the CISG framework, conformity can concern quantity, quality, description and packaging. Goods should correspond with the contractual requirements and, subject to the Convention’s rules and the parties’ agreement, may also need to be fit for ordinary purposes or a particular purpose made known to the seller.

The precise contract remains central.

Approved Samples Can Be Critical

If the Turkish supplier produced goods based on an approved sample, compare the delivered shipment with that sample.

Preserve the original approved sample, technical drawings, photographs, emails and approval records.

Quality Standards Should Be Identified Precisely

A buyer should avoid simply stating that the goods are “poor quality.” Identify the actual deviation: dimensions, chemical composition, material grade, color, strength, performance, contamination, tolerances, packaging or another measurable characteristic.

Specific evidence is considerably stronger than a general complaint.

The Buyer Has an Inspection Obligation

Under the CISG, the buyer is generally expected to examine the goods, or cause them to be examined, within as short a period as is practicable in the circumstances.

What is practicable depends heavily on the goods and transaction.

Inspection Timing Can Vary

Fresh products, industrial machinery, raw materials and complex components cannot necessarily be inspected in the same manner.

The nature of the defect also matters. Some defects are immediately visible, while others may emerge only during processing, installation or use.

Hidden Defects Require Separate Analysis

A defect that could not reasonably have been detected during ordinary initial inspection may raise different timing questions from an obvious defect.

The buyer should document when the hidden problem first became discoverable and what testing revealed it.

Notice of Non-Conformity Is Critical

One of the most important CISG issues is whether the buyer notified the seller of the non-conformity within a reasonable time after discovering it or after it ought to have discovered it.

The notice should also specify the nature of the non-conformity sufficiently.

Avoid Vague Complaints

A message saying “the shipment is unacceptable” may create unnecessary disputes about whether proper notice was given.

Where possible, identify affected products, invoice, batch, quantities, defect type, inspection findings and supporting evidence.

There Is Also an Important Two-Year Rule

The CISG contains an outside period under which the buyer generally loses the right to rely on lack of conformity if notice is not given within two years from the date the goods were actually handed over, unless that limit is inconsistent with a contractual guarantee period.

This does not mean that every buyer automatically has two years to complain. The separate requirement to notify within a reasonable time remains critically important.

Contracts May Contain Shorter Operational Procedures

International sales agreements frequently contain inspection periods, claim procedures or quality-control mechanisms.

These provisions should be analyzed alongside the CISG to determine their legal effect.

Can the Foreign Buyer Reject the Entire Shipment?

Not every defect gives the buyer an immediate right to reject all goods.

The seriousness and scope of the non-conformity matter. If only a limited quantity is defective, remedies may need to be considered in relation to the affected portion.

Fundamental Breach Is Particularly Important

Avoidance of the contract is a serious CISG remedy and generally requires the legal conditions for avoidance to be satisfied. A central concept is fundamental breach.

A defect that substantially deprives the buyer of what it was entitled to expect under the contract may present a very different case from a minor correctable deviation.

Can the Seller Repair the Goods?

Depending on the circumstances, cure may be relevant. A Turkish seller may propose repair, correction, reprocessing, supplementary delivery or another solution.

The buyer should evaluate whether the proposed cure can be completed without unreasonable delay or inconvenience and whether it genuinely resolves the contractual non-conformity.

Can the Buyer Demand Replacement?

Replacement of goods is a significant remedy and is not automatically available for every minor defect.

The nature and seriousness of the breach, applicable CISG requirements and circumstances of the transaction should be assessed before demanding substitute goods.

Price Reduction May Be an Alternative

Where non-conforming goods are retained, the buyer may potentially seek an appropriate price reduction under the CISG framework.

This can be commercially preferable where the goods remain usable but have a lower value because of the defect.

Damages Can Also Be Claimed

A buyer may potentially claim damages resulting from the seller’s breach, subject to the CISG’s requirements.

Possible losses may include direct commercial losses associated with the defective goods and, depending on the circumstances, additional consequential losses.

Foreseeability Matters for Damages

CISG damages are not unlimited. The foreseeability framework is important when determining recoverable loss.

If a specialized component was intended for a critical production line, evidence showing that the Turkish seller knew the commercial purpose may become important.

The Buyer Must Mitigate Loss

A party claiming damages is expected to take reasonable measures to reduce its loss.

Allowing defective goods to deteriorate unnecessarily, continuing production despite an obvious defect or incurring avoidable storage expenses may complicate a later damages claim.

Preserve the Goods

Do not destroy, modify or dispose of disputed goods before considering evidentiary consequences.

The seller may dispute the alleged defect and request an opportunity to inspect.

Preserve Representative Samples

For bulk commodities, chemicals, food products, textiles and industrial materials, representative samples may become essential.

Sampling methodology should be documented carefully so that the seller cannot easily argue that the tested sample was unrepresentative.

Independent Laboratory Testing Can Be Important

Where the disagreement concerns measurable quality characteristics, an independent laboratory or expert examination may provide critical evidence.

The report should identify the product, batch, sampling method, test methodology and results.

Joint Inspection Can Reduce Evidentiary Disputes

Where commercially practical, inviting the Turkish seller to participate in an independent inspection can help create a stronger factual record.

If the seller refuses, preserve evidence of the invitation.

Photographs and Videos Should Be Organized

Visual evidence should identify the relevant shipment and defect rather than consist of disconnected images.

Preserve original files, dates and contextual information.

Do Not Alter Defective Goods Without Documentation

If urgent processing or repair is commercially necessary, document the original condition first.

Keep records of repair costs, rejected quantities, scrap and resulting usable quantities.

Check the Incoterms Rule

The applicable Incoterms rule can affect delivery, transport responsibilities, risk allocation and evidence concerning when damage may have occurred.

However, Incoterms should not automatically be treated as replacing the CISG’s rules concerning contractual conformity.

Distinguish Manufacturing Defects From Transit Damage

A damaged product is not necessarily evidence of defective manufacture.

Inspect packaging, container condition, loading, moisture exposure, temperature records and carrier documents to determine whether the problem arose during transportation.

Risk Transfer Can Become Critical

If the goods were damaged after risk passed to the buyer, the seller may argue that it is not responsible for the resulting deterioration.

The chronology of loading, carriage, delivery and inspection should therefore be reconstructed.

Notify the Carrier Where Necessary

If transport damage is possible, the buyer should protect claims against the carrier or cargo insurer as well as rights against the seller.

Waiting for the seller dispute to be resolved may cause separate transport claim deadlines to expire.

Quality Certificates Should Be Examined

If the Turkish seller supplied certificates of analysis, inspection certificates or quality documents, compare them with independent findings.

A discrepancy may become important evidence concerning contractual conformity.

Third-Party Inspection Certificates Can Affect the Dispute

Some international contracts require pre-shipment inspection by an agreed inspection company.

Determine whether the certificate is contractually final, merely evidentiary or subject to challenge for latent defects.

The Turkish Seller Should Receive Prompt Notice

Send a structured notice identifying the contract, shipment, affected goods, defects, inspection findings and requested response.

The communication should preserve legal rights without making unsupported allegations.

Do Not Declare Contract Termination Too Quickly

A buyer that announces cancellation without satisfying the applicable legal requirements may itself face allegations of breach.

Before declaring avoidance, analyze whether the non-conformity is sufficiently serious and whether the seller retains relevant cure rights.

Seller’s Refusal to Cure Can Change the Situation

If the defect is serious and the Turkish supplier refuses or fails to provide an effective solution, the buyer’s position regarding stronger remedies may become more substantial.

Document every proposed solution and response.

Partial Non-Conformity Requires Careful Analysis

If 5 percent of a shipment fails specification, the legal consequences may differ significantly from a situation where the entire shipment is unusable.

Separate conforming and disputed quantities where reasonably possible.

Installment Contracts Can Be More Complex

Where goods are supplied through repeated deliveries, defects in one installment can raise questions about that delivery and, in serious cases, future installments.

The buyer should not automatically terminate an entire long-term supply relationship because of one defective delivery without analyzing the applicable CISG rules.

Non-Payment Can Create Counterclaims

A foreign buyer that withholds the entire purchase price because of a limited quality problem may face a payment claim from the Turkish seller.

The relationship between the defect and the amount withheld should therefore be considered carefully.

Letters of Credit Can Complicate Quality Disputes

Where payment is made under a letter of credit, the bank’s documentary obligations are generally distinct from the underlying quality dispute.

A buyer should not assume that a defective shipment automatically permits the issuing bank to refuse payment under otherwise compliant documents.

Contractual Dispute Resolution Must Be Checked

Determine whether the contract contains arbitration, jurisdiction or mediation provisions.

The correct forum can be just as important as the substantive CISG claim.

Foreign Buyers Should Preserve the Complete Contract File

Maintain the signed agreement, purchase orders, amendments, specifications, approved samples, emails, invoices, packing lists, inspection reports, laboratory results, transport documents and notices.

International quality disputes are often won or lost through documentary consistency.

Turkish Sellers Should Also Act Quickly

A Turkish exporter receiving a quality complaint should immediately identify the affected batch, preserve production records, obtain quality-control data, request photographs and test reports and consider inspecting the goods.

Ignoring the buyer’s complaint can make a manageable commercial problem significantly larger.

Review Manufacturing Records

Production dates, raw-material batches, machine settings, quality-control results and employee records may help establish whether the alleged defect originated at the Turkish factory.

Check Whether Other Customers Reported the Same Problem

If products from the same production batch were sold elsewhere without complaints, those records may be relevant, although they do not automatically disprove the particular buyer’s claim.

Review the Buyer’s Storage Conditions

A product can leave Turkey compliant and deteriorate because of improper storage after delivery.

Temperature, humidity, stacking, contamination and shelf-life conditions may therefore require investigation.

Avoid Destroying Evidence During Rework

If the buyer intends to reprocess the goods, both parties should consider documenting the condition through an expert inspection before the original evidence disappears.

Settlement Can Be Commercially Efficient

Quality disputes often involve continuing business relationships. Replacement shipments, discounts, repair contributions or future-order credits may provide commercially sensible solutions.

Any settlement should clearly state what claims are resolved.

2026 Practical Strategy for Foreign Buyers

A foreign buyer discovering quality problems in Turkish goods should immediately segregate the disputed products, preserve samples and photographs, review the contract and CISG applicability, conduct an appropriate inspection, notify the Turkish seller promptly and specifically, obtain independent technical evidence where necessary, quantify the affected quantity and financial loss, preserve carrier and insurance claims and avoid declaring avoidance until the legal requirements have been assessed.

For Turkish exporters, the strategy should be equally disciplined: preserve production evidence, investigate the complaint, request access to the goods, analyze whether notice was timely and sufficiently specific, distinguish manufacturing defects from transit or storage damage and evaluate cure before the dispute escalates.

Frequently Asked Questions

Does the CISG apply automatically to every purchase from a Turkish seller?

No. The parties’ places of business, applicable CISG rules and contractual choice-of-law provisions should be examined.

How quickly must the foreign buyer inspect the goods?

The CISG generally requires examination within as short a period as is practicable in the circumstances. The appropriate period depends on the goods and transaction.

How quickly must the buyer notify the Turkish seller of a defect?

The buyer generally must give notice within a reasonable time after discovering or when it ought to have discovered the non-conformity.

Does the buyer always have two years to complain?

No. The two-year rule is an outside limitation under the CISG conformity-notice framework; it does not eliminate the requirement to provide notice within a reasonable time after discovery or when the defect should have been discovered.

Can the buyer reject the entire shipment because some goods are defective?

Not automatically. The extent and seriousness of the non-conformity and the applicable remedies should be examined.

Can the buyer cancel the contract?

Potentially, where the requirements for avoidance are satisfied, including the CISG’s fundamental-breach framework where applicable.

Can the Turkish seller offer repair or replacement?

Potentially. Cure rights and the circumstances of the proposed remedy should be evaluated under the CISG and contract.

Can the buyer claim both damages and a quality remedy?

Potentially, subject to the CISG’s requirements and avoidance of double recovery.

What evidence should be preserved?

The goods, representative samples, photographs, laboratory reports, inspection records, specifications, approved samples, correspondence, invoices and transport documents can all be important.

What is the biggest mistake foreign buyers make?

Waiting too long to inspect and notify. Even a genuine quality defect can become significantly harder to enforce if the buyer cannot demonstrate timely inspection, sufficiently specific notice and reliable evidence connecting the defect to the goods supplied by the Turkish seller.
