Replacement Purchases After a Chinese Supplier Defaults: Can You Claim the Price Difference?

Legal review: 25 September 2026. This guide concerns business purchases of goods involving a Chinese supplier; it does not assume that every international order is governed by the same law.

A supplier misses delivery and the buyer pays more to obtain comparable goods elsewhere. The additional expense may support a damages claim, but a higher replacement invoice alone does not establish the amount recoverable. The file must connect the original breach, the legal basis for ending the original contract, the replacement transaction and the net loss.

1. Identify the applicable rules before calculating a price difference

Check the parties’ places of business, the goods, the contract and any exclusion of the United Nations Convention on Contracts for the International Sale of Goods (CISG). The CISG can apply to qualifying sales between parties in different Contracting States; selecting Chinese law does not by itself necessarily exclude it. China became a party with effect from 1 January 1988 and has an Article 95 declaration. Application based only on conflict-of-laws rules requires separate analysis. See the official status and declarations and the SPC treaty-application interpretation, effective 1 January 2024.

Under CISG Article 75, a buyer claiming the substitute-transaction price difference must address avoidance of the contract and a replacement purchase made reasonably and within a reasonable time after avoidance. Where PRC domestic contract law governs the issue, Civil Code Article 584 and Article 60 of the SPC Interpretation on the General Provisions of the Contract Book provide a different legal route. Do not combine the two sets of conditions into a single automatic formula.

2. Put the breach, avoidance notice and replacement order on one timeline

Record the agreed delivery obligation, any extension, what remained undelivered, the supplier’s response and the buyer’s notices. A missed date does not automatically give a right to avoid the whole contract. Under the CISG, Articles 25, 26 and 49 require examination of the grounds and notice; Article 49(1)(b) addresses non-delivery following an appropriate additional period. An urgent replacement purchase is a commercial step, not itself an avoidance notice.

For an Article 75 claim, preserve the notice and evidence of its communication, the replacement order date and the reason for acting then. A purchase made before avoidance cannot simply be labelled an Article 75 transaction; any alternative damages basis needs separate assessment. PRC domestic-law termination likewise requires its own grounds and notice analysis. The non-delivery and prepayment refund guide explains the preceding decision.

3. Show that the replacement was a reasonable substitute

Compare quantity, specification, quality, delivery location, lead time, currency, taxes, freight and payment terms. A better specification, extra quantity or a different delivery arrangement may require an adjustment. Preserve competing offers where reasonably available, but do not invent a rule requiring three quotations. An urgent deadline may explain a higher price; it does not dispense with proof of necessity and reasonable choice.

Question	Documents to preserve
What did the original supplier owe?	Signed terms, purchase order, approved specifications and delivery changes.
Why was replacement necessary then?	Default correspondence, notices, project dates and contemporaneous procurement notes.
Were the goods and prices comparable?	Alternative quotations, specification comparison and freight/tax adjustments.
Did a replacement transaction actually occur?	Replacement contract, invoice, payment record, delivery and acceptance documents.
What costs or benefits offset the loss?	Saved transport costs, credits, refunds and any usable original goods.

Article 60 of the SPC contract interpretation (Fa Shi [2023] No. 13, effective 5 December 2023) addresses an actual substitute transaction after lawful termination. If its price clearly departs from the local market price when that transaction occurred, the breaching party may seek calculation by reference to the market price instead. Keep the market evidence even when the replacement has already been paid for.

4. Separate the replacement price difference from other losses

Illustration only: assume comparable goods cost USD 10,000 under the original contract and USD 12,000 under a reasonable replacement contract. A provisional price difference is USD 2,000. If an additional USD 500 of necessary expense is independently recoverable and USD 200 of original costs was saved, the provisional net figure is USD 2,300. Those assumptions require evidence; this is not a predicted award.

Show a prepaid amount still held by the original supplier in a separate restitution line. Do not add the entire replacement purchase price as damages on top of a refund without accounting for the original price the buyer would have paid. Likewise, do not count a cost inside the replacement price and again as a separate expense. Downstream penalties, lost profits and urgent freight need their own causation, foreseeability and amount evidence.

CISG Articles 74 and 77 address recoverable loss, foreseeability at contract conclusion and reasonable mitigation. Under PRC domestic law, Civil Code Articles 584 and 591 and Article 63 of the contract interpretation address corresponding matters, including avoidable loss, extra benefits and saved expenses. Contractual limitations and any asserted exemption also require review.

5. A quotation alone is not a completed replacement purchase

If the buyer has not bought replacement goods, say so. CISG Article 76 provides a current-price route where the contract has been avoided and its conditions are met, including the relevant time and place and the absence of a purchase or resale under Article 75. A single supplier’s unaccepted quotation is not automatically the legally relevant current price.

Under PRC domestic law, Article 60 also addresses lawful termination without a substitute transaction, using the market price at the place of performance within a reasonable period after the breach. That reference is not identical to the CISG rule. Explain the market, dates and comparability; assess any other available loss measure separately. Do not delay reasonable mitigation solely to improve a damages spreadsheet.

6. Prepare a focused China claim review

Send an initial summary identifying the supplier, original contract price, delivery obligation, notices, replacement status and the amount in dispute. A useful next step is to review the available claim, missing evidence, dispute-resolution clause and identifiable assets in China. Settlement, arbitration or litigation should be assessed against both the merits and collection prospects; a legal claim does not guarantee recovery.

Official legal texts: CISG, Articles 1, 6, 25–26, 49 and 74–77; PRC Civil Code, Articles 563–566, 584 and 591 (effective 1 January 2021); and the SPC instruments linked above. Transitional rules and the facts of the transaction must be checked for an individual dispute.
