CISG vs Chinese Domestic Contract Law: Key Differences for Foreign Buyers

Foreign buyers purchasing goods from Chinese suppliers operate under one of two legal regimes: the United Nations Convention on Contracts for the International Sale of Goods (CISG) or PRC domestic contract law under the Civil Code. Which regime applies determines the buyer's rights on critical issues — how quickly defects must be reported, when the buyer can cancel the contract, how damages are calculated, and whether the buyer can require specific performance. The differences are not theoretical; they affect the outcome of disputes and the strength of the buyer's bargaining position during contract negotiations.

When Each Regime Applies

As discussed in detail elsewhere, CISG applies automatically under Article 1(1)(a) when both parties have their places of business in different Contracting States. China is a CISG Contracting State (since 1988), so a purchase from a German, American, French, Japanese, or Australian buyer is governed by the CISG unless the parties explicitly exclude it. A contract that specifies "governed by PRC law" does not exclude the CISG because the CISG is part of PRC law as a ratified treaty.

PRC domestic contract law (the Civil Code, effective January 1, 2021) applies when the CISG is excluded by the parties, when one party is in a non-Contracting State (such as the UK, which has not ratified the CISG), or when the transaction does not involve a "sale of goods" within the CISG's scope (for example, service contracts, distribution agreements, or construction contracts).

Contract Formation

Under CISG Articles 14-24, a contract is formed when an offer is accepted. An offer must be sufficiently definite — it must indicate the goods, and expressly or implicitly fix or make provision for determining the quantity and the price (Article 14(1)). Acceptance is effective when it reaches the offeror (Article 18(2)), and an acceptance with modifications is a counter-offer unless the modifications are not material (Article 19).

Under PRC Civil Code Articles 471-493, the formation rules are broadly similar but include additional provisions. Article 483 provides that acceptance takes effect when it reaches the offeror — consistent with CISG. But Article 490 adds that when the parties agree to conclude a contract in written form, the contract is formed when both parties sign, seal, or affix fingerprints. If one party has performed its main obligation before signing and the other party accepts, the contract is formed by performance. This additional rule creates a safety net for contracts where formalities were not completed — a situation that arises frequently in China trade.

Inspection and Notice of Defects

This is where the regimes diverge most significantly. Under CISG Article 38, the buyer must examine the goods "within as short a period as is practicable in the circumstances." Under Article 39(1), the buyer must give notice of non-conformity "within a reasonable time" after discovery. Article 39(2) sets an absolute cutoff: the buyer loses the right to rely on non-conformity if notice is not given within two years from the date the goods were actually handed over.

Under PRC Civil Code Article 621, the buyer must inspect the goods within the agreed inspection period. If no period is agreed, the buyer must inspect promptly and give notice within a reasonable period after discovering or when they should have discovered the non-conformity. For goods with a quality guarantee period, the guarantee period applies. For goods without a guarantee period, if the buyer does not give notice within two years from the date of receipt, the buyer is deemed to have accepted the goods — unless the seller knew or should have known that the goods did not conform.

In practice, the CISG framework gives more flexibility because "reasonable time" is determined by the circumstances of each case, and CIETAC tribunals have been willing to consider industry practice and the nature of the defect. PRC domestic law's two-year rule functions similarly to the CISG's two-year cutoff, but the "reasonable period" for notice after discovery has been interpreted more strictly by some Chinese courts.

Remedies for Breach

CISG provides four main remedies: requiring specific performance (Article 46), reducing the price in proportion to the deficiency (Article 50), claiming damages (Article 74), and avoiding the contract for fundamental breach (Article 49 combined with Article 25). Avoidance — the CISG equivalent of cancellation — is only available when the breach is "fundamental," meaning it substantially deprives the buyer of what it was entitled to expect.

PRC Civil Code provides broader termination rights. Under Article 563, the buyer can terminate when the contract's purpose cannot be achieved due to breach, which is a lower threshold than CISG's "fundamental breach." The Civil Code also provides for specific performance (Article 577), damages (Article 584), and penalty clauses (Article 585) — with the important qualification that courts can adjust penalties that are "excessively higher" than actual loss.

The practical difference is significant. Under the CISG, a buyer who receives goods with moderate quality defects — defects that are serious but do not "substantially deprive" the buyer of expected benefits — cannot avoid the contract and must instead seek a price reduction or damages. Under PRC domestic law, the same buyer may be able to terminate if the defects prevent the buyer from achieving the contract's purpose, which Chinese courts have interpreted more broadly than the CISG's fundamental breach standard.

Damages Calculation

Both regimes use a foreseeability test for damages, but the application differs. Under CISG Article 74, damages equal the loss suffered plus lost profits, provided the loss was foreseeable "at the time of the conclusion of the contract" as a "possible consequence of the breach." Under PRC Civil Code Article 584, damages include the loss suffered and expected profits, but shall not exceed the loss "foreseeable or that should have been foreseen at the time of contracting as a possible consequence of the breach."

The PRC formulation uses "shall not exceed," which some Chinese courts have interpreted as a hard cap rather than a general limitation. In practice, this means PRC domestic law may produce lower damages awards for the same breach scenario. Under the CISG, international arbitration practice tends to interpret foreseeability more liberally, potentially including consequential losses that Chinese courts might exclude.

Specific Performance

CISG Article 46(1) gives the buyer the right to require specific performance, but Article 28 limits this right: a court is not bound to order specific performance unless it would do so under its own domestic law. Since Chinese courts regularly order specific performance under the Civil Code, this limitation is less significant when the dispute is resolved in China.

PRC Civil Code Article 577 provides a straightforward right to require continued performance (继续履行). Chinese courts grant specific performance more readily than common law courts, making this a meaningful remedy for buyers who need the supplier to actually deliver conforming goods rather than simply pay damages.

Which Regime to Choose

For buyers, the choice between CISG and PRC domestic law depends on the transaction's risk profile. The CISG is generally preferable for buyers who want an internationally recognized framework, who may need to enforce in multiple jurisdictions, or whose home-country lawyers need to advise on the governing law. PRC domestic law may be preferable for buyers who want broader termination rights or whose transaction falls outside the CISG's scope.

The decision should be made during contract drafting with advice from licensed PRC attorneys who understand how both regimes operate in practice — not just in theory, but in how CIETAC tribunals and Chinese courts actually apply them. A bilingual contract review with red, yellow, and green risk classifications will flag the governing law and CISG applicability issues and provide a recommendation tailored to the buyer's specific situation.
