Quality Control Inspections

Advantages of QC Inspections

Supplier Audits

Avoid Costly Product Defect and Shipment Delays

Quality control (QC) inspections minimize the amount of costly defects by detecting non-conformances throughout the production cycle.

QC Inspections

Identify or Explore Corrective Actions

Inspections help you determine the overall quality of your order, and determine the need to issue corrective actions before any products leave the factory.

Product Testing

Protect Your Company's Brand and Reputation

Sub-standard products result in customer complaints and damage your reputation. Product quality inspections help ensure consistent customer satisfaction.

For inspections, 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 your specific requirements. Discovered defects are classified as major, minor, or critical depending on inspection plans. If you have your QC standard and procedure, we have no concern to follow your documentation.

Inspection service reports and results with digital photos will be emailed to you within 24 hours of the service through our secure online database so that you can quickly authorize your suppliers to ship your products.

What Type of Inspections Do I Need?

There are several types of inspections available throughout the production process; First-Article, In-Process and Pre-Shipment inspections. As one of the longest serving inspection companies in Asia, all our Account Managers are very capable to help choose the best source inspection service to fit your requirements.

What Other Services Reduce My Quality Risks?

Pro QC has an international reputation for providing independent third-party inspection and testing services. However, our quality solutions do not stop with QC inspections. Pro QC provides solutions throughout the supply chain, from sourcing, manufacturing, to final delivery.


First-Article Inspections

Pro QC inspects first-article samples prior to volume production. This verifies that product specifications are being met and avoids unnecessary reengineering work later.

In-Process Inspections

An in-process QC inspection evaluates random samples from production lots when the process is ~20-30% complete. This confirms the quality of your product and allows any necessary changes to be addressed early on, reducing rework time and costs.

Pre-Shipment Inspections

During a pre-shipment inspection, our engineers verify that finished goods conform to your 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 your specifications and golden samples in advance and use them to ascertain the quality of the products produced at your supplier.

Container Loading Supervision

Pro QC ensures that proper methods are employed during product loading, and we verify counts on-site.
