Meaning
Mandatory formal communication informs downstream partners and regulatory bodies of a modification to the production workflow or raw materials. Issuing a process change notice ensures that customers can evaluate the impact of the change on their own systems before it is implemented. This notification is a requirement for maintaining quality certifications in industries like automotive or medical manufacturing.
Modification Scope
Technical changes that trigger the notice include shifts in the chemical composition of materials, the introduction of new machinery or a change in the manufacturing location. The document describes why the change is occurring and provides data to show that the product performance remains consistent. Evaluation of these changes prevents unexpected failures in the supply chain.
Approval Chain
Supplier agreements usually require that a process change notice is sent at least ninety days before the proposed implementation date. The customer has the right to request samples for testing or to audit the new process before giving formal approval. Production may not proceed with the new method until a written sign-off is received from the purchasing party.
Regulatory Compliance
Chinese administrative laws for regulated industries, such as medical device manufacturing under the National Medical Products Administration, require that any major change is registered with the state. Failure to file a process change notice for a regulated component can result in the loss of the license to sell the product in the domestic market. Operational transparency is the goal of this formal notification system.
