China Tightens Automotive Supplier Payment Rules for NEVs

China Introduces New Automotive Supplier Payment Requirements

China automotive supplier payment rules are being tightened under a new notice issued by the Ministry of Industry and Information Technology (MIIT) and the State Administration for Market Regulation (SAMR). Released on September 7, the Notice on Promoting Standardized Supplier Payments by Automotive Enterprises and Optimizing Payment Terms targets payment practices in the new energy vehicle (NEV) industry. The measures are intended to improve payment timeliness, regulate competition, and protect suppliers’ legitimate rights and interests. The notice responds to problems identified during implementation of the Initiative on Standardizing Supplier Payments, issued by the China Association of Automobile Manufacturers (CAAM) in September 2025.

Guidelines Standardize Supplier Payment Practices

The new requirements focus on how automotive enterprises establish, calculate, and manage supplier payment terms. The guidelines call for clearly defined starting dates for payment periods, standardized and efficient acceptance procedures, full and timely settlement, and compliant, convenient payment methods. They also address partial payments during price negotiations, stronger protection for small and medium-sized enterprises (SMEs), and procedures for exceptional circumstances. By defining expectations across these areas, the notice seeks to reduce uncertainty for suppliers and create more consistent payment practices across the automotive supply chain in China.

SME Suppliers Receive Specific Payment Protections

SME suppliers receive specific payment protections under the notice. Automotive enterprises are encouraged to pay SMEs for goods within 30 days after acceptance and no later than 60 days, while cash payment is encouraged for these transactions. If a contract does not specify the payment method, payments to SMEs should be made in cash. Commercial bills, electronic accounts receivable instruments, and other non-cash payment instruments should not be used as substitutes for cash. These provisions are designed to improve suppliers’ access to timely funds and reduce payment-related pressure on smaller businesses serving automakers in China.

Automakers Encouraged to Adopt Longer Supplier Contracts

The notice also establishes expectations for longer-term supplier relationships and contract practices. Automotive enterprises are encouraged to maintain stable partnerships with suppliers, with each contract having a term of at least one year. Contract provisions should be fair and reasonable and should maintain a balanced allocation of rights and interests. Enterprises should not seek price reductions without considering suppliers’ cost floors or potential quality and safety risks. They should also avoid pressuring suppliers to reduce supply prices in exchange for shorter payment terms, linking commercial negotiations to payment timing in ways that could disadvantage suppliers.

Implementation and Oversight Measures

Implementation will combine enterprise self-assessment reports, third-party surveys and assessments, public disclosure of assessment results, and government supervision and inspections. This approach gives the notice a broader enforcement and transparency framework than guidance based solely on voluntary internal review. For automakers and suppliers operating in China, the practical focus will be on aligning contracts, acceptance procedures, payment methods, and supplier-management processes with the stated expectations. The measures are intended to address difficult payment issues while encouraging more stable commercial relationships throughout the NEV supply chain.

Supplier Payment Requirements Under the New Notice

The notice establishes several operational expectations that directly affect supplier payment management. The following table summarizes the principal requirements described in the announcement, including the payment timing encouraged for SME suppliers and the contract and pricing practices expected of automotive enterprises. Together, these measures emphasize timely settlement, transparent commercial terms, and protection against payment practices that could place disproportionate financial pressure on suppliers.

Industry Impact & Outlook

The notice could increase the importance of disciplined working-capital and supplier-management practices for automotive enterprises, particularly across the NEV supply chain. Clearer payment expectations may provide smaller suppliers with greater predictability in receiving funds, while longer contracts and limits on payment-related pricing pressure could encourage more stable commercial relationships. The combination of self-assessment, third-party assessment, public disclosure, and government oversight also raises the importance of compliance processes for automakers and suppliers. As implementation progresses, enterprises in China are likely to focus on reviewing payment terms, acceptance procedures, contracts, and supplier practices against the requirements outlined by MIIT and SAMR.
