Our Service Offerings

Inspection services for every stage of production—from initial checks to pre-shipment quality control.
Initial Production Check (IPC)

Initial Production Check (IPC)

An important quality control activity performed at the completion of batch 5%-10% to ensure that the quality of the product remains consistent throughout the production process and meets customer requirements.

Mid-production inspection (DPI)

Mid-production inspection (DPI)

Sampling inspection at product completion of 30%-50% helps optimize the production process and quality to ensure product compliance and conformity to specifications. This inspection strengthens the management of suppliers and guarantees on-time delivery of orders and customer satisfaction.

Final production inspection (FRI)

Final production inspection (FRI)

It is the most effective way to confirm the quality level of a shipment, which typically requires 100% of goods to be manufactured and at least 80% of goods to be boxed. InspectionOnline performs AQL sampling of products subject to Final Production Inspection in accordance with ANSI/ASQC Z1.4 (ISO 2859-1) and generates a detailed inspection report based on the defined AQLs.

Pre-Shipment Inspection (PSI)

Pre-Shipment Inspection (PSI)

It refers to the systematic quality inspection carried out after the products have been manufactured and packaged, and before formal delivery or shipment. Its core objective is to confirm that the products meet the requirements of customer orders, regulations, standards and trade terms, and to avoid returns, claims or logistics delays due to quality problems.
