Direct answer
A foreign buyer preparing a China supplier claim should preserve native electronic records, physical samples, transaction documents, and a clear loss calculation before negotiations alter the evidence. Chinese civil proceedings generally require each party to prove the facts supporting its case, so a commercially persuasive complaint is not enough unless the buyer can connect the contracting entity, agreed terms, breach, notice, causation, and claimed loss.
Applicable legal framework
The PRC Civil Code, adopted May 28, 2020 and effective January 1, 2021 governs contract performance, breach, remedies, damages, mitigation, and related civil rights.

Operational steps
- Verify the supplier’s exact registered Chinese entity, seal, signatory, and payment account.
- Freeze the evidence set: signed contracts, purchase orders, native emails and chats, bank records, specifications, inspection files, shipping documents, and supplier admissions.
- Preserve representative products and packaging with batch identifiers and a written chain of custody.
- Obtain an independent technical assessment that applies the agreed standard and explains sampling.
- Send a written breach notice identifying orders, defects, requested cure, deadline, and reserved rights.
- Prepare an itemized loss table separating refund, cover purchase, inspection, freight, storage, recall, and other supported amounts.
- Review governing law, court or arbitration, service, limitation, preservation, and security before filing.
Evidence checklist
- Business licence and official registry records for the contracting supplier.
- Contract, amendments, purchase orders, samples, drawings, quality and delivery clauses.
- Native communications with metadata and complete conversation context.
- Payment, invoice, logistics, customs, inspection, test, photograph, video, and sample-custody records.
- Defect notice and delivery proof, supplier response, repair or replacement history, and settlement admissions.
- Invoices and calculations proving direct loss, mitigation, saved costs, salvage, and any cover purchase.
Common risk and exceptions
The main risk is evidence loss: goods may be repaired, resold, mixed, returned, or destroyed while messages and platform records expire. Contractual inspection deadlines, liability caps, notice clauses, governing-law provisions, the CISG, limitation periods, destination-market rules, and buyer-provided designs may change the analysis. A court’s treatment of one evidentiary record is case-specific and should not be presented as a guaranteed result.
