In this post, we will talk about various types of quality inspections i.e. before, during, and after manufacturing. Plus, which of them is most widely used in international trade.
All the import companies nowadays should perform the inspections by hiring 3rd party quality service providers or ask the inspectors of your own company. You should prefer hiring quality control inspectors from countries like India, China, Vietnam, and other low-cost countries.
What is Quality Inspection?
The word inspection refers to an activity for checking the quality of the product, whereas the audit refers to analyzing the manufacturing processes and companies. The quality control inspector always has to follow the pre-established checklist which is based on the specifications of the product. All the inspected products can be used as components for production, half-finished products or finished products before shipping it to the customers.
According to an ISO 2859 standard third party inspection is an activity for measuring, testing, examining, or gauging one or more characteristics of any product or service, and comparing the results with the required specifications of the product in order to find out whether the conformity is established or not.
Why Inspecting Earlier is Generally Better
As the main reason, we would like to emphasize on important principles of quality management “The more early we work on removing errors, the better it is”.
There are total six methods to deal with the defects in a product. These defects can either be prevented or corrected, and they fall into three broad categories: production, delivery, and development.
According to various studies across many industries, it has been shown that there is a ratio between time and cost for development:production: delivery of 1:10:100. Meaning that each error will cost 10 times more to fix than to fix it with development, and 100 times more if the error reaches to the customer.
This is the reason why doing quality control check in the end is very risky. However, you don’t have to wait until everything is done.
Types of Most Common Quality Inspections
The three main types of quality inspections for import companies to look at the quality of their supplied products. Each company should try to choose the quality inspections according to their needs and requirements.
- Before Production Inspection
“Throw in, Throw out”, most of the manufacturing companies cannot turn the defective inputs into useful products. Moreover, these problems are very difficult to detect once components or materials are integrated into the final product.
Therefore, to decrease the number of quality risks, the inputs of the production can be inspected before the production. Some random samples should be taken and checked visually. Moreover, the buyer of the product should clearly define the acceptable inputs, before giving any more orders.
An inspector with years of experience can easily examine the production of the sample product, to be sure about two things:
- Has the development team communicated about the requirements to the manufacturing company? The equipment used by a manufacturing company similar to the equipment used in making prototypes.
- Has the import company understood the technical requirements of your product? Are they aware of what product client needs?
Before production inspection takes place when the manufacturing of product has already begun. Moreover, it allows quality control inspectors to analyze the process and check the new products sometimes before dispatching it to the customers. However, in some cases, the manufacturing companies says no to stop the production, even the thought the product is not satisfactory at all.
Before production inspection is easily adaptable to customized and complex products. More standard items are also inspected during the production phase.
- During Production Inspection
- Final Production Inspection
These were some of the benefits of conducting early inspections before shipping the final product to the customers. Moreover, an inspection result is not 100% reliable. Even the random sample of the product may be better than the average product, the inspectors can commit a mistake, an inspector might get bribed etc. Therefore, early inspection is better option to go before the actual production of the product has started.
