Supplier Audit & Factory Audit in China

Professional Third-Party Supplier and Factory Audit Services

Supplier audits involve reviewing and evaluating factories according to specific standards. Brands request Factory audit in China to strengthen supply chain management, ensure stable product quality, and avoid risks such as negative publicity and product recalls. These audits also help identify new, high-quality suppliers and improve the quality control of existing suppliers.

As a leading Quality Inspection Company and China Inspection Agency, HQC provides professional Supplier audit and Factory audit in China services. Our audits cover human rights, quality, environmental, and anti-terrorism requirements, helping global buyers assess supplier capabilities, compliance, and production performance.




What Is a Supplier Audit?

A Supplier audit is a comprehensive assessment and verification process of a factory’s production capabilities and performance. Its core purpose is to ensure that all aspects of the supply chain—including production processes, environment, and management systems—meet established quality and safety standards, thereby ensuring that customers receive satisfactory products.

Supplier audits focus not merely on inspections at a specific point in time or for a particular product. Instead, they emphasize a thorough and accurate assessment of the factory’s overall quality management capabilities. This includes a comprehensive evaluation of the factory’s policies, procedures, and records to ensure its ability to consistently deliver high-quality products.

The audit examines the factory’s quality system and related documentation, its size, production capacity, equipment, and processes, covering all areas including workshops, warehouses, offices, power distribution rooms, and boiler rooms.




Types of Factory Audits

Factory audits generally fall into the following categories:

·        Social Compliance / Human Rights Audit

·        Quality Management System Audit

·        Environmental Audit

·        Anti-Terrorism / Security Audit (e.g., C-TPAT)

·        Industry-Specific Audit

·        Supplier Evaluation and Capability Audit




Supplier Audit Scope

1. Qualification and Compliance Verification

·        Review the supplier’s quality manual, procedural documents, work instructions, and assess the completeness, standardization, and applicability of its quality management system.

·        Conduct on-site inspections of the supplier’s production site, laboratory, and warehouse to verify the actual operation of its quality management system, including process control, personnel training, and equipment maintenance.

·        Perform sampling inspection or 100% inspection of supplied products to ensure they meet quality requirements and technical standards.

3. Supply Chain Management Capability Audit

·        Assess the adequacy of the supplier evaluation and selection process, ensuring it is based on objective and reliable indicators and criteria.
