Costco, as a leading global membership-based warehouse retailer, is renowned for its carefully selected products and high cost-effectiveness. To maintain its excellent reputation and ensure supply chain compliance and transparency, Costco has established strict social responsibility audit standards, known as the "Costco Social Compliance Audit." This audit is a mandatory evaluation that all factories wishing to become Costco suppliers must pass, aiming to ensure products are manufactured under safe, ethical, and environmentally friendly conditions.

I. Core Philosophy and Objectives

The core of the Costco audit is to practice corporate social responsibility, ensuring its supply chain complies with international labor standards, local laws and regulations, and the brand's own ethical standards. Its goals extend beyond risk management to driving continuous improvement among suppliers, achieving the following key points:

• Protect Labor Rights: Ensure workers enjoy fair treatment, a safe working environment, and legal labor protections.

• Maintain Brand Reputation: Avoid damage to the brand image due to supply chain issues through ethical sourcing.

• Promote Sustainable Development: Encourage suppliers to establish long-term, stable social responsibility management systems, balancing economic, social, and environmental benefits.

II. Audit Content and Standards

The Costco audit is primarily based on its "Code of Conduct," covering the following core areas:

Labor Rights

• Prohibition of Forced Labor: No use of prison, bonded, or forced labor.

• Prohibition of Child Labor: Strict verification of employee age documents to ensure no workers under the legal age.

• Anti-Discrimination and Harassment: Prohibit discrimination in hiring, compensation, and promotion based on gender, race, religion, etc., and strictly prohibit abuse or harassment.

• Freedom of Association: Respect employees' legal rights to form and join trade unions.

• Health and Safety: This is a key focus area of the audit, with particular attention to:

• Fire Safety: Unobstructed emergency exits, complete and regularly inspected fire equipment, effective emergency lighting and alarm systems.

• Workplace Safety: Machinery equipment guards, electrical safety, chemical management, ventilation, and sanitary conditions (including dormitories and canteens).

Any major safety hazards may lead to audit failure.

• Working Hours and Wages: Working hours must comply with local legal requirements; overtime must be voluntary and legally limited; wages must not be lower than the minimum standard; overtime pay must be paid according to the law; time and payroll records must be accurate and complete.

• Environmental Protection: Factories are required to comply with environmental regulations, properly handle waste, and reduce environmental pollution.

• Business Ethics: Prohibit bribery, corruption, and data falsification; require supply chain transparency and compliance.

III. Audit Process and Results

Costco commissions third-party auditing agencies (such as SGS, BV, etc.) to conduct audits, typically through semi-announced audits (with short advance notice) or unannounced audits. The audit process includes document review, on-site inspection, and employee interviews (conducted separately with management and employees).

Audit results are categorized as:

• Pass: Meets requirements; the factory can receive orders.

• Requires Correction: Non-conformities exist; a Corrective Action Plan (CAP) must be submitted, and a follow-up audit is required.

• Fail: Serious issues found (e.g., child labor, forced labor, critical safety hazards) or falsified records; the factory will be terminated from cooperation and blacklisted.

IV. Significance for Suppliers

The Costco audit is known for its strictness and comprehensiveness, particularly emphasizing health and safety and the authenticity of working conditions. Passing the audit not only helps factories meet Costco's requirements but also drives them to optimize their management systems and enhance market competitiveness. Meanwhile, Costco focuses on long-term cooperation with suppliers, often providing improvement guidance to support factories in continuously enhancing their social responsibility performance.

The Costco audit is a core mechanism for maintaining ethical standards and product quality in its supply chain, reflecting the brand's deep commitment to consumers, employees, and society. For suppliers, passing this audit is an important milestone in integrating into the global high-standard supply chain system.
