BYD (BYD) Factory Audit Consulting Services

Guangdong HQC Inspection Co., Ltd. is a comprehensive third-party inspection, testing and certification organization. As a professional BYD factory audit consulting and automotive supply chain audit firm, we provide full-scope guidance to help suppliers successfully pass BYD‘s rigorous factory audits and gain access to the world’s leading new energy vehicle supply chain.

BYD Factory Audit: The Gateway to a Premier Supply Chain

BYD, a global leader in new energy vehicles, ranked 91st on the Fortune Global 500 in 2025 and sold over 4.78 million new energy vehicles annually. To manage this scale, BYD has established a three-dimensional audit system centered on quality control, social responsibility, and workplace safety. Passing product samples does not guarantee audit approval—many suppliers fail at this critical checkpoint. BYD factory audits cover all production material suppliers, including both primary and auxiliary material suppliers.

Why BYD Factory Audit Matters:

Access to a Premier Supply Chain – Gain stable orders from the world‘s leading NEV manufacturer

Brand Endorsement – Passing BYD’s strict audits demonstrates excellence in quality management and social responsibility

Continuous Improvement – BYD‘s dynamic tiered management system drives ongoing optimization

BYD’s "Three-Tiered" Audit Framework

Based on its 2025 supply chain audit standards, BYD has established a "Technology Compliance, Supply Chain Resilience, ESG Responsibility" three-tiered framework:

Tier 1: Technology Compliance (40%)

Suppliers must hold certifications such as IATF 16949, demonstrate complete APQP (Advanced Product Quality Planning) documentation, maintain CPK (Process Capability Index) ≥ 1.33, and have laboratory equipment with CNAS accreditation where applicable. BYD‘s quality system audit is built on ISO 9001 standards with additional BYD-specific requirements. The audit covers both QSA (Quality System Audit) and QPA (Process Audit).

Tier 2: Supply Chain Resilience (30%)

BYD evaluates whether suppliers have dual-source supply for core raw materials, whether their ERP system can interface with BYD’s SRM platform in real time, and whether OEE (Overall Equipment Effectiveness) meets required standards.

Tier 3: ESG & Social Responsibility (30%)

This is the "hidden killer" for many SMEs. BYD integrates social responsibility into supply chain management, auditing against RBA (Responsible Business Alliance). Key focus areas include:

Working Hours & Payroll Compliance: Monthly overtime ≤ 36 hours; wages paid via bank transfer with records retained for at least 2 years

Occupational Health & Safety: PPE for chemical-handling positions; bi-annual occupational health examinations

Environmental Protection: ISO 14001 certification encouraged; battery supply chain to achieve 15% emission reduction from 2022 baseline by 2025

Workplace Safety: Explosion-proof design for battery workshops; hazardous waste handled by licensed operators

BYD‘s Multi-Method Audit Approach

BYD employs a "three-method combination" to prevent superficial compliance:

Unannounced Audits (40%) : Random on-site inspections without prior notice, verifying safety measures and working hour records

Document Verification (30%) : Rigorous review of quality system documents, payroll records, and hazardous waste disposal contracts

Employee Interviews (30%) : Random one-on-one interviews with frontline workers to verify actual conditions

Supplier Dynamic Tiered Management

BYD implements ABC dynamic tiered management based on supplier performance scores across quality, social responsibility, and safety:

Grade    Score     Management Measures

A Grade      ≥90      Priority order allocation; audit cycle every 2 years

B Grade       75–89    Corrective actions within 3 months; re-audit the following year

C Grade      <75   Cooperation suspended; full corrective actions required before reapplication
