During Production Inspection (DUPRO)
A During Production Inspection (DUPRO) is a quality control process conducted while manufacturing is in progress. It evaluates semi-finished products, components, and ongoing production processes to confirm that manufacturing is proceeding according to required specifications. This inspection supports production stability and provides visibility into process conditions before full order completion.
ECQA provides During Production Inspection services for buyers, brands, and importers who require independent verification during the manufacturing process. Our inspectors assess semi-finished goods, production line conditions, and workmanship based on standardized procedures and internationally recognized sampling methods.
Key Aspects of During Production Inspection
- Semi-Finished Product Review: Checks assembly accuracy, workmanship, and conformity to requirements.
- Component Verification: Confirms that components used during production meet specifications.
- Production Line Evaluation: Reviews workflow, process setup, and operational stability.
- Workmanship Checks: Assesses visual quality, finishing, and consistency.
- Sampling Under AQL: Applies Acceptance Quality Limit (AQL) sampling based on ANSI/ASQC Z1.4 / ISO 2859-1.
- Process Control Review: Evaluates adherence to production steps, work instructions, and inspection points.
- Tooling and Equipment Readiness: Confirms machinery condition and calibration status.
When to Conduct a During Production Inspection
A DUPRO should be scheduled when the following conditions are met:
- 10 to 80 percent of total production is completed.
- Semi-finished products are available for evaluation.
- Verification is required before production progresses to later stages.
- The order involves detailed assembly, special components, or strict workmanship requirements.
- Ongoing monitoring is needed to confirm consistency across batches or repeated orders.
How ECQA Conducts During Production Inspections
ECQA inspectors review production conditions and semi-finished products based on structured quality control procedures. The inspection focuses on process stability, assembly quality, and material use.
- Random sampling of semi-finished units using AQL tables.
- Inspection of components used during production.
- Review of assembly flow, workstation setup, and process control.
- Assessment of workmanship and finishing quality.
- Evaluation of equipment, tooling, and calibration readiness.
- Monitoring of production progress relative to the schedule.
- Photo-supported DUPRO report delivered within 24 hours.

Frequently Asked Questions (FAQ) About During Production Inspection (DUPRO)
DUPRO is a quality control inspection conducted during the manufacturing process to identify defects and ensure compliance with product specifications before final production is completed.
DUPRO inspections are typically performed when 10-80% of production is completed. This allows manufacturers to detect and correct issues before they affect the entire production batch.
DUPRO helps maintain product quality, reduce defects, minimize costly rework, and ensure adherence to the production schedule. It also allows manufacturers to optimize their production process in real time.
A DUPRO inspection typically involves checking raw materials, semi-finished products, production tools, and adherence to specifications. Inspectors also assess production efficiency and identify potential bottlenecks.
By identifying issues early in production, DUPRO prevents costly rework, reduces material waste, and minimizes delays that could impact delivery timelines.
DUPRO inspections can be performed by third-party quality control companies like ECQA, which provide experienced inspectors to ensure compliance with quality standards.
A Pre-Production Inspection (PPI) is conducted before manufacturing begins to check raw materials, components, and initial setup. A DUPRO inspection takes place during production to monitor quality and prevent defects.
