Quality Control Inspection

Quality-control-inspetion

We represent your interests at the factory, by employing international AQL (Acceptance Quality Limit for Quality Control Inspection) we verify that the specifications and features of the products being manufactured meet your terms and conditions

You can specify when and at which stage of the production process to execute this service

Final inspection takes place when the order has been produced, good are packaged into cartons and ready to export

We suggest to perform Quality Control inspection while the merchandise is still in production line, Ex; at 20%, 50% and/or 70% of the production stages, ensuring you will have time enough to implement corrective measures

Quality Control Inspection:

Performing a (QCI) while the manufacturing process is taking place, can assist you to monitor the production techniques and the quality of the products at the time being to ensure pre-established terms as well as delivery schedules are being fulfilled

Such inspections can be performed at different stages of the production process, for example, there are pre-production inspections in which we visit the factory´s facilities to review the quality of raw materials and components to verify their compliance with your specifications, as well as their availability in stock to ensure the production schedules will be respected.

Quality control inspection not only provide useful feedback and accurate insights to what is going on at the production lines, but to create standards, and quality programs we can help you design so we can train your suppliers and help them upgrade their performance.

Why quality control inspection?

1.- Guarantee the quality of your products in every stage of the process

2.- Rely on accurate feedback on the status of your products with enough anticipation

3.- Avoid wasting time and money for having to reject your purchase order

4.- Establish Key Performance Indicators and improve your relationship with your suppliers

AQL for quality control inspection:

‘AQL ‘stands for ‘Acceptance Quality Limit ‘, and is defined as the “quality level that is the worst tolerable” in ISO 2859-1. It represents the maximum number of defective units, beyond which a batch is rejected. Importers usually set different AQLs for critical, major, and minor defects. Most Asian exporters are familiar with this type of setting. (“qualityinspection.org”)

In practice, three types of defects are often distinguished. For most consumer goods, the limits are

-0% for critical defects (totally unacceptable: a user might get harmed, or regulations are not respected).

 

-2.5% for major defects (these products would usually not be considered acceptable by the end user).

 

-4.0% for minor defects (there is some departure from specifications, but most users would not mind it).

 

Display of the AQL charts:

If you ordered different products, consider each product as a separate lot. (The quantity of each product is the lot size). If you ordered only one product, the lot size is the total batch quantity.

Different inspection levels will command different numbers of samples to inspect, for the effects of this exemplification we are using Level II

 

To follow this example, let’s assume your lot size is composed between 10,000 to 35,000 pieces, and based on the inspection level agreed upon is level II, meaning that your code letter is “M”.

Our code letter is “M”, so we would need to pick up a badge of 315 pieces out of the total lot; assuming you´ve established an AQL at 2.5% for major defects, and 4.0% for minor defects, so based upon this metrics, no more than 10 products with MAJOR defects will be allowed and no more than 14 products with MINOR defects will be accepted.

For example, if 15 products with MINOR defects were found, and 11 of them with MAJOR defects were detected, the products are rejected, but if we find 12 pieces with MINOR defects and only 7 pieces with MAJOR defects, then the lot is accepted.

Other criteria usually employed when conducting a QCI are:

-Packaging conformity (barcodes, inner packing, cartons, shipping marks, logos…).

-Product conformity (aspect, workmanship…). If all the products are in red color instead of orange, there is no need to count each sample as a defect. It makes more sense to refuse for product conformity.

-Specific tests defined in the inspection checklist (they might not be performed on all inspected samples if they are time-consuming or destructive).
