What Should You Do If a Korean Supplier Fails to Deliver Goods?

Short Answer

If a Korean supplier fails to deliver goods, the buyer should first:

• review the contract, purchase order, payment terms, and delivery documents;
• preserve evidence of the supplier’s non-delivery;
• confirm whether the buyer has performed its own obligations; and
• send a clear written notice demanding performance.

Depending on the circumstances, the buyer may consider demanding delivery, claiming damages, purchasing substitute goods, terminating the contract, or pursuing legal action in Korea.

However, the proper response depends on the contract terms, the delivery deadline, the reason for non-delivery, whether the buyer has performed its own obligations, and whether the buyer can prove actual loss. In Korea, immediate termination or aggressive legal action without proper documentation may create unnecessary risk.

Why Supplier Non-Delivery Matters in Korean Transactions

Supplier non-delivery is one of the most common problems in cross-border transactions involving Korea.

Foreign buyers may face serious business disruption if a Korean supplier:

• fails to deliver products on time;
• refuses shipment;
• delivers only part of the order; or
• stops communicating after receiving payment.

This issue commonly arises in manufacturing agreements, purchase orders, OEM or ODM supply arrangements, distribution agreements, and repeated commercial dealings without a detailed written contract.

In practice, the key question is not only whether the supplier failed to deliver. The buyer must also prove what was ordered, when delivery was due, what obligations the buyer had to perform, and how the supplier’s failure caused loss.

Step 1: Review the Contract, Purchase Order, and Payment Terms

The first step is to confirm the supplier’s exact delivery obligation.

Relevant documents may include the written contract, purchase orders, invoices, pro forma invoices, specifications, delivery schedules, emails, messages, shipping documents, and prior course of dealing between the parties.

The buyer should confirm:

• the goods, quantity, and specifications;
• the delivery date, delivery place, and Incoterms;
• the payment terms and payment status;
• inspection or acceptance procedures; and
• remedies for delay or non-delivery.

The payment terms are especially important. In many sale or supply transactions, the supplier’s obligation to deliver and the buyer’s obligation to pay may be connected or concurrent.

For example, the supplier may argue that delivery was not yet due if the buyer failed to:

• pay the required deposit;
• open the required L/C;
• provide final specifications;
• approve samples; or
• supply necessary materials.

For this reason, the buyer should check not only the supplier’s breach, but also whether the buyer was ready and able to perform its own obligations.

Step 2: Preserve Evidence of the Supplier’s Failure

Evidence is critical in Korean contract disputes.

The buyer should preserve all communications showing that the supplier agreed to deliver goods and failed to do so. Important evidence may include:

• emails and written messages;
• purchase orders and invoices;
• KakaoTalk, WhatsApp, or other messenger records;
• shipping schedules and delivery confirmations;
• payment records;
• inspection records; and
• internal records showing business disruption.

If the buyer suffered downstream losses, such as customer penalties, lost sales, emergency procurement costs, or production delays, those losses should be documented as soon as possible.

In many disputes, the supplier may later argue that the delivery date was flexible, payment was not properly made, specifications were unclear, materials were unavailable, export procedures were delayed, or the buyer changed the order. Good documentation helps address these defenses.

Step 3: Send a Written Demand for Performance

Before terminating the contract or claiming major remedies, the buyer should usually send a written notice demanding performance.

Under Korean law, where performance is delayed but still possible, termination is generally safer after the buyer has given a notice demanding performance and a reasonable additional period for delivery.

A written demand should usually identify:

• the relevant contract or purchase order;
• the undelivered goods;
• the agreed delivery schedule;
• the supplier’s failure to deliver;
• the requested delivery deadline; and
• the buyer’s reservation of rights.

This type of written notice is important because it creates a clear record that the buyer demanded performance and gave the supplier an opportunity to cure.

Can the Buyer Terminate the Contract?

Potentially, yes.

If the supplier’s failure to deliver constitutes a serious breach, the buyer may be able to terminate the contract. This is especially relevant where the supplier refuses to perform, repeatedly misses delivery deadlines, or the delay makes the goods commercially useless.

However, termination should be handled carefully. If the breach is still curable, or if the contract requires a cure period, immediate termination may be challenged as premature.

Before termination, the buyer should review:

• whether the contract has a termination clause;
• whether notice and cure are required;
• whether time was essential to the transaction;
• whether the supplier clearly refused performance; and
• whether the buyer performed or offered to perform its own obligations.

In some cases, termination without an additional cure period may be possible, such as where:

• the contract was time-sensitive;
• late delivery defeats the purpose of the transaction;
• the supplier clearly and finally refuses to perform; or
• the contract expressly permits immediate termination.

However, these exceptions should be applied carefully. In practice, a clear written record is usually important before the buyer treats the contract as terminated.

---

Can the Buyer Claim Damages for Non-Delivery?

Yes. If the supplier’s non-delivery constitutes a breach of contract, the buyer may claim damages for non-delivery.

Potential damages may include:

• additional procurement costs;
• price differences for substitute goods;
• reasonable logistics costs;
• storage costs;
• costs caused by production disruption; and
• other losses caused by the supplier’s failure to deliver.

However, damages are not awarded simply because the buyer is dissatisfied. The buyer generally needs to prove:

• the supplier’s breach;
• actual loss;
• a causal connection between the breach and the loss; and
• the amount of damages with supporting evidence.

This is especially important for downstream losses, such as customer penalties, lost profits, production shutdown losses, or damage to business relationships. These may be treated as more difficult or fact-sensitive claims, particularly if the supplier did not know the specific downstream consequences when entering into the transaction.

For example, if the buyer claims that late delivery caused penalties from its own customer, the buyer may need to show that the Korean supplier knew or could reasonably foresee that the goods were intended for that specific downstream delivery schedule.

---

Can the Buyer Purchase Substitute Goods?

In many commercial situations, the buyer may need to purchase substitute goods from another supplier to reduce business disruption.

This may be commercially necessary, and the additional cost may potentially be claimed as damages if properly supported.

The buyer should preserve evidence showing:

• why substitute procurement was necessary;
• whether the substitute price was reasonable;
• when the substitute goods were purchased;
• how the additional cost was calculated; and
• how the cost was caused by the Korean supplier’s non-delivery.

The buyer should also consider sending a prior notice stating that, if the supplier does not deliver within the required period, the buyer may procure substitute goods and seek recovery of resulting losses.

This helps show that the buyer acted reasonably and attempted to reduce the damage rather than simply increasing the claim.

---

What If the Buyer Already Paid in Advance?

If the buyer already paid the Korean supplier in advance, the buyer may seek:

• delivery of the goods;
• return of the advance payment;
• termination of the contract;
• damages; or
• other remedies depending on the contract and facts.

Where the contract is validly terminated due to non-delivery, return of the payment may be claimed as part of the restoration or refund process. Depending on the circumstances, interest and additional damages may also become issues.

However, the buyer should structure the claim carefully. If the buyer simply demands a refund without clearly addressing termination, return obligations, remaining goods, partial delivery, set-off issues, or other contract rights, the dispute may become more complicated.

If the supplier appears financially unstable, the buyer may also need to consider whether provisional attachment or other preservation measures are available in Korea before filing a full lawsuit.

---

What If the Contract Has a Liquidated Damages or Penalty Clause?

Some supply contracts contain liquidated damages, delay penalty, or late delivery penalty clauses.

These clauses may become important if the supplier fails to deliver on time. Depending on the wording, they may provide a predetermined amount of compensation for delay or non-delivery. However, they may also affect how damages are calculated or limit disputes over the amount of damages.

Foreign buyers should therefore review whether the contract contains:

• delay penalties;
• liquidated damages;
• limitation of liability;
• exclusion of consequential damages; or
• force majeure clauses.

These provisions can significantly affect the buyer’s recovery strategy.

---

What If the Supplier Claims Force Majeure or Production Problems?

Suppliers sometimes rely on excuses such as material shortages, factory problems, subcontractor delays, export issues, logistics problems, government restrictions, or force majeure.

These arguments should be reviewed carefully. A supplier is not automatically excused simply because performance became more difficult or expensive.

The legal effect depends on:

• the contract language;
• the cause of non-delivery;
• foreseeability;
• whether the event was beyond the supplier’s control;
• whether the supplier was at fault; and
• whether the supplier complied with notice and evidence requirements.

If the contract has a force majeure clause, the buyer should review the exact definition, notice deadline, supporting document requirement, and consequences of force majeure.

In practice, the buyer should request written explanation and supporting documents from the supplier rather than relying only on informal explanations.

Practical Considerations for Foreign Buyers

When a Korean supplier fails to deliver goods, foreign buyers should focus on both legal rights and commercial leverage.

Key practical issues include:

• contract wording;
• purchase orders and delivery records;
• payment status;
• buyer’s own performance;
• written demand and cure period;
• substitute procurement;
• damage calculation;
• termination strategy;
• dispute resolution clause; and
• whether the supplier has recoverable assets in Korea.

If the supplier is still operating and wants to preserve the business relationship, negotiation may be effective. If the supplier is avoiding communication, financially distressed, or refusing both delivery and refund, legal action in Korea may need to be considered more quickly.

In cross-border disputes, the buyer should also check whether the contract requires Korean court litigation, foreign litigation, or arbitration, and whether enforcement against Korean assets will be necessary.

---

Conclusion

If a Korean supplier fails to deliver goods, the buyer should not rely only on informal complaints or repeated verbal requests.

The buyer should review the contract and purchase documents, confirm its own performance obligations, preserve evidence, send a clear written demand, evaluate whether termination is legally available, and document any damages caused by the non-delivery.

For foreign companies, a careful and evidence-based response can improve the chances of recovering losses, negotiating a practical solution, or pursuing legal remedies against the Korean supplier if necessary.
