Inspector Online provides supplier and factory audit services to importers, brands, and purchasing teams. By conducting on-site assessments of company qualifications, quality management systems, production capacity, supply chain management, and social responsibility, we help clients assess supplier risks before entering into partnerships.
A supplier audit is a systematic evaluation of a supplier’s or factory’s qualifications, management systems, production capacity, and on-site operations. Audits are typically conducted for onboarding new suppliers, conducting risk assessments prior to establishing a partnership, annual reviews, or supplier performance management.
Depending on the client’s needs, the scope of the audit may include corporate qualifications, quality management, production equipment and capacity, supply chain processes, social responsibility, environmental management, and specific industry requirements. Once the audit is complete, the client can use the report to determine whether the supplier meets procurement and partnership requirements.
Verify suppliers' business licenses, industry qualification certificates, etc., to ensure that they have the qualifications and conditions to operate legally.
Evaluate whether the supplier complies with relevant laws and regulations, industry standards, and the enterprise's procurement policies, including but not limited to requirements on environmental protection, labor rights, and business ethics.
Review the quality manual, procedure documents, and work instructions to assess the completeness and suitability of the quality management system; conduct on-site inspections of production areas, laboratories, and warehouses to verify the implementation of process controls, personnel training, and equipment maintenance; and, when necessary, perform sampling or 100% inspections of products to confirm compliance with quality requirements and technical standards.
Assess whether the vendor evaluation and selection process for suppliers is well developed and based on objective and reliable indicators and guidelines.
Review suppliers' supply chain management processes, including procurement, production, logistics and inventory management, to ensure that they are efficient, stable and traceable.
Assess suppliers’ performance in the areas of labor rights, environmental protection, and business ethics—including working hours, wages and benefits, non-discrimination, energy conservation and emissions reduction, business integrity, fair competition, and intellectual property protection—to ensure they meet relevant requirements and provide a foundation for sustainable cooperation.
Depending on the industry and the nature of the products being purchased, supplier audits may also include specific audit requirements. For example, in the food industry it may be necessary to audit a supplier's food safety management system; in the pharmaceutical industry it may be necessary to audit a supplier's GMP (Good Manufacturing Practices) compliance, etc.
Upon completion of the audit, the audit team will prepare a detailed audit report summarizing the issues and highlights identified in the audit and making recommendations for improvement. The supplier should carry out rectification and enhancement according to the recommendations in the audit report to continuously improve its capability and quality level.
Service Coverage: We can arrange supplier audits and factory audits in China’s major manufacturing regions and coordinate services in select overseas regions based on project requirements.
Report Timing: Once the on-site audit is complete, the formal audit report is typically provided on the next business day or by a mutually agreed-upon date.
Pricing Information: Audit fees are determined based on the type of audit, the factory’s location, the scope of the audit, the workload, the number of auditors, and travel arrangements; the final fee is subject to the official quote.
Service Boundaries: Supplier audits are based on the results of on-site inspections, document reviews, and interviews; they are not the same as government regulatory inspections, certification by accreditation bodies, or legal due diligence.
Report Sample: You can view sample supplier audit or factory audit reports to understand the report structure, audit findings, and recommendations for improvement.
Supplier audits do not merely inspect a specific batch of products; rather, they assess whether a factory has the capability to consistently and reliably deliver conforming products. Key audit areas typically include quality management, production processes, staffing, equipment condition, documentation, and on-site compliance, helping the buyer identify potential supply risks.
Get a Supplier Audit Quote Review the factory's quality system and related documents, the factory's size, production capacity, production equipment, process flow and other aspects of the audit, covering the factory's various workshops, warehouses, offices, power distribution rooms, boiler rooms and other areas.
Audit Criteria: The scope of the audit can be customized based on customer requirements, procurement standards, industry requirements, and applicable quality management system elements—for example, by referencing certain management requirements from ISO 9001:2015.

Outdoor furniture is widely used in the overseas procurement market.

Anyone in international trade has heard the saying: ”Accurate sampling leads to accurate inspection.” With a shipment consisting of tens of thousands of items, it’s impossible to unpack and inspect every single one. Whether the sampling method is scientific directly determines whether the inspection results accurately reflect the true quality of the entire shipment. Many importers have learned this the hard way—factories place good-quality goods on the top layers, and when only a few surface boxes are sampled, problems with the goods at the bottom of the shipment are often discovered only after the shipment has been loaded onto the ship. This article focuses on third-party inspections…
Air fryers, coffee makers, hair dryers, blenders, and humidifiers—small appliances are a perennial category in China’s cross-border e-commerce exports: they have moderate unit prices, rapid product updates, and frequently produce bestsellers. However, the quality risks associated with these products are also the most ”multi-faceted”: cosmetic defects are visible, while functional defects only become apparent once the product is plugged in; even if the main unit is flawless, customers will still return the product upon unboxing if an accessory is missing or the instruction manual is printed in the wrong language. This article follows the complete workflow of pre-shipment inspection (PSI),…

Passing a pre-shipment inspection does not guarantee that the goods will arrive at the port in good condition. After a shipment passes pre-shipment inspection, it must still undergo container loading, inland transport, terminal handling, and a 3–5-week ocean voyage—during which the temperature inside the container fluctuates significantly between day and night, damage caused by under-filling, incorrect loading, crushing, moisture, or shifting is often not discovered until the container is opened at the port of destination. By that time, the goods have already left the port, making it difficult to determine liability. Container Loading Supervision (Container Loading S…
