Resolving Primary Sub-Tier Mill Certificate Disputes under PRC Civil Code Article 620
PRC Civil Code Article 620 bars latent raw material claims unless buyers execute incoming chemical verification and serve formal notice within agreed windows.
Material Non-Conformance Notice
Meaning
Formal quality documentation issued during an audit records specific failures of a material batch to meet the agreed technical specifications or regulatory standards. The material non-conformance notice serves to document the exact deviations identified, such as incorrect chemical composition or dimension errors. It represents the official start of the corrective action process, preventing the affected materials from being used in production.
Internal Quarantine
When an inspector issues a deficiency report, the factory must isolate the defective batch to prevent its integration into the assembly line. The material non-conformance notice requires the production manager to place physical hold tags on the material and move it to a secure quarantine zone.
Supplier Response
The manufacturer has a set period to respond with a corrective action plan that addresses the root cause of the issue. If they dispute the material non-conformance notice, they must present counter-evidence from an accredited laboratory.
Contractual Execution
Foreign buyers use this notice as the primary legal evidence when claiming compensation or demanding a replacement batch from a Chinese supplier. Without a formal material non-conformance notice, the buyer cannot easily prove that the factory was notified of the defect within the legally required timeframe under Chinese trade law. This document is also required to support insurance claims or to justify the withholding of outstanding payments to the manufacturer.
By securing a signed copy, the buyer protects their financial position and ensures that the factory takes responsibility for the quality failure.
