Third-Party Quality Inspection Services

Product Inspection Services

For third-party quality inspection services, Pro QC recommends the International Inspection Standard ANSI Z.1.4-2003 (ANSI Sampling Table) to determine the number of units that will be randomly selected for evaluation.

Samples are checked against a detailed inspection plan for appearance, applicable functionality, packaging integrity, workmanship, and the client’s specific requirements. Discovered defects are classified as major, minor, or critical depending on the inspection plan. We have no concern to follow our customer’s QC standards, procedures, and documentation.

Pro QC’s quality control inspection services apply to all industries and are tailored to the requirements of each project. From 100% to AQL-based inspections, our solutions cover the entire spectrum of quality inspections and include First Article Inspections (FAI), In-Process Inspections (DUPRO), Pre-Shipment Inspections (PSI), and Container Loading Supervision (CLS).

Our product inspection reports and results with digital photos are delivered to our clients within 24 hours of the service through our secure online client center so that product shipments can be quickly authorized.

Advantages of QC Inspections


Avoid Costly Product Defect and Shipment Delays

Quality control (QC) inspections minimize the number of costly defects by detecting non-conformances throughout the production cycle before it is too late.


Identify or Explore Corrective Actions

Product quality inspection services help companies determine the overall quality of their order, and determine the need to issue corrective actions before any products leave the factory.


Protect Brand and Reputation

Sub-standard products result in customer complaints and damage brand reputation. Third-party product quality inspections help ensure consistent customer satisfaction and maintain brand integrity.

Our Range of Third-Party Quality Inspection Services

Quality and purchasing departments demand that their suppliers meet high product quality specifications. As a global third-party inspection company, Pro QC offers quality solutions throughout the entire production cycle. This allows our customers to identify defects, ensure product quality, and reduce the cost of poor quality.

Pro QC’s local quality control inspectors and quality consultants work in partnership with our clients and are deployed accordingly to the project requirements and their specialization. Our team includes specialized quality inspectors in textile, footwear, furniture, medical devices, electrical, electronics, automotive, mechatronics, mechanical, welding, coating, painting, piping, and more.

Our range of quality control inspection services include:

As a global third-party inspection company, Pro QC inspects first-article samples prior to volume production. This inspection in quality verifies that product specifications are being met and avoids unnecessary reengineering work later.
An in-process QC inspection, also called: During Production inspection, evaluates random samples from production lots when the process is circa 20-30% complete. This confirms the product quality and allows any necessary changes to be addressed early on, reducing rework time and costs.
During a pre-shipment inspection, our engineers verify that finished goods conform to the most stringent specifications. A pre-shipment inspection (PSI) generally occurs when production is 100% complete and packaging is 80% complete. For example, if an automotive product or auto part inspection is required, we would request the specifications and golden samples in advance. These would then be used to ascertain the quality of the products produced at the supplier. Pre-shipment inspections are also known as pre-dispatch inspections.
Pro QC ensures that proper methods are employed during product loading, and we verify counts on-site. Products conformance to international standards will also be verified.
