INI, DUPRO, AQL, FRI Inspections
We perform AQL inspections along the entire supply chain — before, during, and after production — to identify defects, verify conformity to specifications/standards, and prevent non-compliant shipments.
We apply recognized sampling plans, classify defects (critical/major/minor), and issue photographic reports with recommendations and CAPA actions.

Types of AQL Inspection
We select the most effective inspection stage based on risk, timing, and client requirements, allowing us to detect issues at the point of greatest impact (quality, cost, and lead time).
1. Pre-Production Inspection (INI)
Preventive verification of materials/components and production setup to avoid structural non-conformities from the outset.
- Raw materials and components control
We verify quality, certifications, and compliance with specifications before production starts, reducing the risk of upstream defects. - Verification of conformity to client standards
We align suppliers and departments with agreed technical/aesthetic standards (golden samples, tolerances, preliminary tests).
2. During-Production Inspection (DUPRO)
In-process inspection (20–50% progress) to identify defect trends and correct them without stopping the production line.
- Timing: 20–50% of production
Mid-cycle sampling allows deviations to be detected early, when corrective action is still economically feasible. - Early detection and correction of defects
We analyze causes (process, materials, setup) and activate corrective measures to prevent defect multiplication.
3. Pre-Shipment Inspection (PSI)
Final verification on completed lot (≥80–100%) and packaging, before payment and shipment.
- Inspection of finished and packed goods
Ensures that products meet the required quantity, assortment, and packaging conditions. - Random sampling according to AQL
Samples are selected statistically, ensuring lot representativeness and result reliability. - Verification of specifications, aesthetics, and functionality
We check dimensions, performance, finishes, labeling, and appearance against agreed technical and customer standards.
4. Container Loading Inspection (CLI)
Supervision of packing, palletization, and container loading to preserve integrity and conformity in transit.
- Packaging and container loading check
We verify protections, stacking, moisture, seals, and shipping documents to minimize damage and disputes upon arrival.

How an AQL Inspection Works
We apply a standard methodology: define acceptance limits, perform random sampling, inspect based on checklists, and classify defects. We then formalize results and recommendations through detailed reports.
1. Definition of AQL standard
We define AQL levels and sampling plans based on risk, product category, and client defect tolerance.
2. Sample Selection
We extract random samples according to AQL tables to obtain statistically sound evidence.
3. Quality Control
We evaluate visual/functional defects, safety, and regulatory compliance with the required tools and tests.
4. Report & Recommendations
We provide photo reports, counted quantities, AQL outcomes (pass/fail), and proposed corrective/preventive actions.

AQL Defect Classification
Properly classifying the impact of defects guides decisions on lot acceptance, rework, or rejection.
Critical defects: 0% acceptable.
Hazardous or safety-non-compliant products are not acceptable.
Major Defects (2.5% acceptable)
Issues that affect product functionality or appearance.
Minor Defects (4.0% acceptable)
Aesthetic imperfections or minor issues that do not affect product use.
Pre-Shipment & Loading: Guaranteed AQL
We plan and conduct AQL inspections (INI, DUPRO, PSI, CLI) using statistical sampling, defect classification, and photographic reports. We help reduce risks, costs, and delays — ensuring shipments meet all specifications.
