• China allows used airframe and engine parts from foreign suppliers.
• Three-year collaboration led to the new policy.
• Qualified used parts can be purchased and installed by Chinese airlines and MROs.
• Regulatory framework established for used serviceable material (USM).

This development may indicate a significant shift in China's aviation supply chain strategy, potentially increasing access to cost-effective parts and reducing maintenance costs for Chinese airlines. The move could also suggest a growing recognition of the importance of used serviceable material in supporting the country's rapidly expanding aviation industry, which may benefit foreign suppliers and could lead to increased collaboration between Chinese and international aviation stakeholders.
