WeChat Group Messaging Risks in Chinese Factory Operations
Informal WeChat instructions bypass factory change control, destroying legal enforceability under PRC law and creating severe scrap and rework risks.
Unpriced Factory Rework
Meaning
Non invoiced production adjustment defines the process where a manufacturer executes corrective actions, modifications, or repairs on a batch of defective goods without charging the buyer for the additional labor or material costs. In contract manufacturing, unpriced factory rework requires the supplier to absorb the financial burden of correcting quality failures that were caused by their own operational mistakes, design deviations, or poor workmanship. This rework arrangement stops applying once the defective goods have been successfully repaired, re-inspected, and approved for shipment by the buyer’s quality representative.
For international brands, ensuring that the cost of rework falls on the factory is essential for maintaining product margins and encouraging the supplier to focus on quality control. The process requires the buyer’s quality team to document the defects, issue a formal rework instruction, and verify that the factory’s corrective actions have resolved the issues. This rework serves as the standard remedy for quality failures discovered during factory inspections.
Operational Procedures
Defect correction on the assembly line must be handled through clear, structured procedures that prevent further damage to the components and ensure that the repaired goods meet the original specifications. The unpriced factory rework process must start with the supplier’s engineering team developing a detailed rework plan that specifies how the defects will be fixed and what materials and tools will be used. This plan must be approved by the buyer’s quality representative before the factory can begin the repairs.
The factory must then execute the rework in a separate, controlled area of the facility to prevent the defective goods from being mixed with compliant inventory. This process must be closely monitored by the quality team to ensure that the repairs are done correctly.
Financial Allocation
Cost responsibility for rework must be clearly defined in the supply agreement to prevent disputes and ensure that the supplier is held accountable for their quality failures. If the factory is responsible for the defects, the unpriced factory rework must cover all costs associated with the repairs, including the labor of the line workers, the cost of any replacement materials, and the use of the factory’s machines and tools. The buyer should not accept any additional charges or invoices for these corrective actions, as they are simply the remedy for the supplier’s failure to deliver compliant goods.
If the supplier refuses to perform the rework without payment, the buyer should have the right to suspend payments or terminate the contract for cause. This financial separation is essential for protecting the buyer’s investment.
Quality Verification
Post rework inspection must be performed on all repaired components to confirm that they meet the agreed specifications before they are authorized for shipment. The unpriced factory rework is not complete until the buyer’s quality inspector has conducted a full re-audit of the batch and issued a formal release certificate. This inspection must use the same sampling plan and testing methods as the original pre-shipment audit to ensure consistency.
If the re-audit reveals that the defects persist or that new issues have been introduced during the repairs, the batch must be rejected again, and the factory must perform further rework or replace the goods at their own expense. This strict quality gate ensures that only compliant goods reach the buyer.
