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.

Frequently Asked Questions

Common Questions About Third-Party Inspection Services

What is a third-party inspection service?
A third-party inspection is an independent on-site assessment carried out on behalf of the buyer. Inspectors check product quality, quantity, workmanship, packaging, labeling, and buyer-specified requirements. The purpose is to provide objective information before shipment so the buyer can identify potential issues and make informed shipment or corrective-action decisions.
Where can you arrange inspection services?
Inspector Online covers major manufacturing regions in China and can also arrange inspections in many overseas markets. Our service network covers 150+ countries and regions. Availability depends on the inspection location, date, product type, and local inspector availability, so early booking is recommended.
What types of inspection services do you provide?
Common services include Initial Production Check (IPC), During Production Inspection (DUPRO/DPI), Pre-Shipment Inspection (PSI), Container Loading Supervision (CLS), Factory Audit, and Supplier Audit. Different services apply to different stages of production and sourcing, and the appropriate service depends on your order status and quality-control needs.
What information is required to book an inspection?
You will normally need to provide the inspection date, factory address and contact person, product name and model, order quantity, product specifications or approved samples, and any specific inspection requirements. Packaging artwork, shipping marks, manuals, purchase orders, and other relevant documents should also be provided when available.
What is usually checked during a product inspection?
The inspection scope depends on the product and the buyer’s requirements. Typical checks include quantity verification, appearance and workmanship, dimensions and basic functions, packaging, labels and shipping marks, product specifications, and applicable on-site tests. Sampling is normally performed according to the agreed sampling standard or the buyer’s specified requirements.
When will I receive the inspection report?
The official inspection report is normally issued on the next working day after the on-site inspection is completed and is sent to the client in PDF format. Reports are not issued on Sundays or Chinese public holidays; in such cases, the report will be sent on the next working day. The report typically includes inspection results, issue descriptions, and on-site photographs.
How is the inspection fee calculated?
Inspection fees depend on factors such as the service type, product complexity, inspection location, number of inspectors required, workload, and travel arrangements. Additional charges may apply for remote locations or special service requirements. Once the basic order information is provided, we will issue a clear quotation, and the final fee will be based on the confirmed quotation.
What happens if quality problems are found during inspection?
If quality issues are found, the inspector will document the findings and provide supporting photographs or other relevant evidence. The issues will be included in the inspection report so the buyer can discuss corrective action, rework, or shipment arrangements with the supplier. A reinspection can also be arranged after corrective action when required. The final shipment decision remains with the buyer.
