Start with the shipment, not the headline
This article addresses business purchases from a Chinese supplier where import duties have changed the buyer’s decision to proceed. A June 2025 US Chamber coalition letter recorded orders being paused or cancelled during tariff changes. That is evidence of a business problem, not a finding that those cancellations were legally justified, and its historical rates should not be used as current rates.
Have the relevant customs adviser verify classification, origin, valuation, entry timing and the measure applicable to the particular shipment. This article does not calculate current tariffs. Rerouting cargo or changing an invoice is not a substitute for a lawful origin analysis. An import prohibition, export control or licence restriction needs separate examination of what conduct is actually prohibited.
For an international goods sale, check CISG Articles 1–6, treaty declarations and any effective exclusion. A choice of Chinese law does not automatically exclude the CISG. Matters outside its scope require their own governing-law analysis; the buyer’s nationality or office location alone does not settle it.
The four facts that determine your options
Build this short decision record before sending a cancellation or withholding an instalment.
- The measure: official publication and commencement dates, affected products and origin, relevant shipment and verified incremental cost.
- The bargain: when the order was accepted; duty allocation, fixed or adjustable price, trade-term version and named place, change-in-law clause and cancellation mechanism.
- The work: committed materials, completed units, resale options, shipment status, instalment dates and storage or port charges.
- The actual ground: reduced resale margin, a genuine performance impediment, an agreed exit event, or an independent failure by the supplier.
Compare four routes out of the problem
These routes depend on the governing rules and facts; they are not interchangeable labels.
- Buyer bears the cost and performance remains possible: consider performance or a negotiated change. Increased import costs do not by themselves oblige the seller to refund the advance.
- An express adjustment or exit clause applies: test its event, base date, thresholds, notice, negotiation period and settlement terms. A generic reference to policy changes may not cover every tariff.
- PRC hardship rules govern the issue: Article 533 may support renegotiation and, if no agreement is reached within a reasonable period, a request to a court or tribunal to vary or terminate. A request is not an accomplished variation.
- There is inability to perform or a separate seller breach: test the relevant exemption and termination conditions independently. The buyer’s tax burden should not be relabelled as seller non-performance.
Hardship and force majeure under PRC domestic law
Civil Code Article 533 requires an unforeseeable major change to the contract’s basic conditions, outside ordinary commercial risk, making continued performance manifestly unfair. Article 32 of the SPC Contract Book interpretation addresses policy changes and abnormal supply or demand affecting prices, with qualifications for actively traded commodities and other specified risk products. There is no universal percentage increase that qualifies a tariff change.
Evidence should explain what was foreseeable when the contract formed, the agreed allocation, the actual cost impact and workable alternatives. Lower margin alone does not establish the threshold. The court’s effective date for a variation or termination need not match the date of the buyer’s stop-order email. A clause excluding Article 533 in advance is invalid under Article 32; that does not remove the claimant’s burden of proof.
Force majeure is a different inquiry under Articles 180 and 590: the event and its effect on inability to perform must be established, with timely notice and supporting proof within a reasonable period. An event occurring after a party was already late does not excuse that delay. Termination under Article 563 for force majeure additionally requires frustration of the contract’s purpose. More expensive imports and legally prohibited imports are not the same fact pattern.
The CISG does not turn Article 79 into a refund button
Article 79 requires proof of an impediment beyond the party’s control which it could not reasonably have taken into account when contracting or avoided or overcome, including its consequences. Notice of the impediment and its effect must reach the other party within a reasonable time. Whether severe cost changes qualify is a fact-specific question; neither automatic exemption nor categorical exclusion is justified.
Article 79(5) preserves rights other than damages. Article 79 itself does not grant a unilateral power to rewrite the price or avoid the contract. Nor should Civil Code Article 533 simply be imported into a CISG-governed issue without analysing the applicable rules. Parties may agree a change or termination under Article 29, subject to relevant writing requirements and reliance.
If the buyer relies on seller breach, Articles 25 and 49 require separate analysis of fundamental breach or the specified non-delivery route following an additional reasonable performance period. Avoidance must be notified under Article 26; restitution after valid avoidance is addressed in Article 81. A fall in the buyer’s resale margin does not establish a seller’s fundamental breach.
What happens to the deposit and cancellation costs?
An English-language ‘deposit’ may be an advance payment rather than the PRC security deposit known as dingjin. Where Civil Code Articles 586–588 apply, the security arrangement and actual payment matter; the portion exceeding 20% of the main contract value does not have that security-deposit effect. Forfeiture or double repayment depends on qualifying breach and failure of contractual purpose, not merely a tariff change.
For valid termination governed by PRC domestic law, Article 566 addresses restitution and other remedial consequences in light of the contract and performance. Examine whether a ‘non-refundable’ provision was incorporated, is valid and applies. Conversely, a buyer cannot assume every pre-delivery production cost belongs to the seller.
Under Articles 584 and 591, and CISG Articles 74–77 where applicable, loss, foreseeability and mitigation matter. Request a breakdown of irrecoverable dedicated materials, resalable goods, saved manufacturing or freight costs, resale proceeds and claimed profit. Avoid double counting. The advance is not automatically a liability cap; nor should the same loss be recovered repeatedly through retained goods, full price and damages.
Prepare an exit evidence pack
Use documents to test both sides’ position, rather than attaching a tariff news story alone.
- Tax impact: official measure, product and origin records, entry timing and a customs calculation separating verified inputs from assumptions.
- Risk allocation: accepted quote, final contract and order, attachments, duty and delivery terms, change-in-law and exit provisions, and complete negotiations.
- Performance and loss: production records, materials and stock, shipment documents, port bills, alternative arrangements, resale quotations and saved expenses.
- Notice and agreement: full requests and replies, signatory authority, notice addresses and delivery records, and express agreement to any production or shipping pause. Keep native files.
Make a negotiated exit executable
A phased order, reduced quantity, later production or lawful resale may be commercially sensible. Obtain agreement and check customs and third-party consequences. Asking the factory to pause is not the same as agreeing a suspension; continued performance under the original bargain can increase the disputed cost.
An exit document should identify the orders, effective date, work in progress and stock ownership, net settlement method, refund currency and date, verified bank details, default remedies and dispute forum. Decide whether any release takes effect only after cleared payment. A promise, a transfer screenshot and funds actually received are different states.
Identify any reserved claim precisely. A unilateral reservation in a payment reference may not undo a signed final release.
Deadlines, dispute route and when to seek advice
Prioritise the next payment, shipment, port, contractual notice and insurance deadlines. Under applicable PRC law, Article 594 provides a four-year limitation period for litigation or arbitration concerning international goods sales; other claims or laws can differ. Termination rights have separate deadlines under Article 564, including agreed or statutory limits and, absent those, the one-year or post-demand reasonable-period rules. Certain CISG avoidance routes also require action within a reasonable time.
Check the valid arbitration agreement or competent court before framing a request for variation, termination, restitution or damages. Identify the Chinese contractual party, payment recipient and realistic assets. Preservation requires its own conditions, security assessment and follow-on filing timetable; a favourable decision is not money recovered.
Obtain transaction-specific advice before an instalment falls due, goods move, a forfeiture or final release is signed, or a unilateral cancellation is sent. China-side legal work can be conducted with English communication; destination-country customs and foreign-law questions may require local professional coordination.
Conclusion
Convert the tariff problem into an evidenced contract decision: the actual duty, agreed risk, performance impact and net exit cost. Establish the legal route before cancelling or demanding repayment. This article is general information, not advice on a particular contract or customs assessment.
