Defective goods from China: how to prove a quality dispute
Quality claims are strongest when the defect is measurable and tied to an agreed requirement.
Updated 28 July 2026
Quick answer
Identify the final agreed standard, document the defect objectively, state the affected quantity and connect the requested remedy to the evidence.
Define the agreed standard
Identify the exact clause, drawing, sample, material name, tolerance, colour, size or workmanship requirement.
Save approvals and revisions so the final specification is clear.
Capture objective evidence
Photograph the whole item and close-ups; use a ruler, scale or test result where appropriate.
For repeated defects, show a representative sample and state how many units were checked.
Connect each defect to the specification
Use a simple table: promised requirement, observed condition, source file and requested remedy.
Avoid exaggeration and separate confirmed facts from suspicions that require testing.
Preserve the goods and originals
Keep original photographs, videos, packaging, labels and inspection records.
Do not alter or destroy potentially relevant evidence while the dispute is active.
Common mistakes
- Using only emotional descriptions
- Claiming a material is fake without a reliable basis
- Showing defects without the agreed specification
- Mixing unrelated complaints into one unclear demand
