How to Send a Demand Letter to a Chinese Supplier

China legal answer: A demand letter to a Chinese supplier should be factual, evidence-based, and tied to a realistic enforcement path. It should not be a generic angry email. A useful demand letter identifies the transaction, the contractual basis, the breach, the evidence, the amount claimed, the requested remedy, the deadline, and the lawful next step if the supplier refuses to respond.

For foreign buyers, the demand letter is often the first serious legal step before settlement, China litigation, arbitration, or evidence preservation. A poorly drafted letter can weaken the buyer’s position by misstating facts, overclaiming damages, waiving rights, or making threats that cannot be carried out.

1. When a Demand Letter Makes Sense

A lawyer-drafted demand letter may be useful when a Chinese supplier:

received payment but did not ship goods;
shipped defective goods and refuses refund or replacement;
missed delivery deadlines and caused downstream losses;
changed price, quantity, specifications, or shipment terms after payment;
ignored inspection failures or warranty claims;
refuses to return molds, tooling, samples, source files, or technical materials;
continues to promise a solution but never provides a concrete repayment or cure plan.

2. What to Prepare Before Sending the Letter

Before sending a demand letter, the buyer should organize the case file. This usually includes:

contract, purchase order, pro forma invoice, quotation, and supplier terms;
payment records and bank transfer evidence;
product specifications, drawings, samples, photos, videos, and inspection reports;
commercial invoice, packing list, bill of lading, airway bill, and warehouse records;
email, WeChat, WhatsApp, platform messages, and supplier admissions;
loss calculation, customer claims, chargebacks, storage costs, and mitigation records;
the supplier’s Chinese legal name, address, business registration information, and known assets.

Evidence should be preserved before the buyer escalates the dispute. See also: What to Check Before Paying a Chinese Supplier.

3. What the Demand Letter Should Include

A practical supplier demand letter should usually include:

Parties and transaction: identify the buyer, supplier, order number, contract date, invoice, shipment, and payment.
Factual timeline: summarize order, payment, production, inspection, shipment, defect discovery, and prior communications.
Contractual basis: identify the agreed specifications, payment terms, delivery terms, warranty, refund, replacement, or dispute clauses.
Breach: explain exactly what the supplier failed to do, with evidence references.
Claim amount: state the refund, replacement, repair cost, price reduction, logistics cost, or other loss with a clear calculation.
Demand: ask for a specific remedy by a specific deadline.
Reservation of rights: preserve the buyer’s rights to pursue litigation, arbitration, evidence preservation, settlement, or other lawful remedies.

4. What to Avoid

A demand letter should avoid common mistakes:

making accusations that cannot be supported by documents;
quoting contract or chat language inaccurately;
claiming unrealistic amounts without a loss table;
threatening criminal reports, customs action, or public exposure without legal basis;
accepting a partial settlement in language that may waive remaining claims;
sending the letter only to a salesperson while ignoring the supplier’s legal entity;
waiting too long when goods, samples, chat records, or payment evidence may disappear.

5. Should the Letter Be in English or Chinese?

For a Chinese supplier, a bilingual or Chinese demand letter is often more effective than an English-only letter. The supplier’s owner, finance department, local counsel, or court-facing personnel may need to understand the legal consequence clearly.

The English version can help the foreign buyer review the content internally. The Chinese version can help create a clear local record if the matter later moves toward negotiation, litigation, arbitration, or evidence preservation.

6. How Long Should the Response Deadline Be?

The response deadline depends on the claim type, urgency, contract terms, and relationship. A payment or refund demand often uses a short but reasonable deadline. A technical cure or replacement goods demand may need more detail and time. The key is that the deadline should be credible and linked to the next step the buyer is actually prepared to take.

7. What Happens If the Supplier Ignores the Letter?

If the supplier ignores the demand letter, the buyer should reassess forum, evidence, asset location, enforceability, cost, and settlement leverage. Possible next steps may include a lawyer follow-up call, structured settlement proposal, evidence preservation, China court litigation, arbitration, or coordinated pressure through lawful business channels.

The right step depends on the contract, the supplier’s Chinese legal identity, the claim amount, available evidence, and whether the supplier has assets that can realistically support recovery.

8. When to Use a China Lawyer

A China lawyer can help verify the supplier’s legal entity, review the evidence, calculate the claim, draft a Chinese or bilingual demand letter, identify the enforcement path, and avoid language that weakens the buyer’s position. The strongest demand letter is not the longest one. It is the one that makes the supplier believe the buyer is organized, documented, and ready to take the next lawful step.
