What is Quality Inspection? A Complete Guide

What is quality control? According to the ISO 2859 standard, quality inspection involves activities such as testing, gauging, examining, or measuring one or more product characteristics. Quality inspection can help companies determine if their products comply with marketing and quality standards.

What is Quality Inspection?

Quality inspection is a process of ensuring that products or services meet specified requirements and standards before they are delivered to customers or released into the market. It involves evaluating, verifying and testing items for defects, deviations, or non-conformities that may affect their performance, safety, reliability, and usability.

Quality inspectors usually carry out on the basis of a checklist developed by third-party inspection companies or buyers. The results of the inspection is then compiled into a report, that indicate whether or not the product conform to the specifications.

An effective quality management solution can enhance product quality, streamline quality processes and workflows reduces the time and resources, and help ensure compliance with industry regulations, standards, and best practices, reducing the risk of non-compliance penalties and legal issues.

Quality Inspection vs Quality Control

Quality inspection is a process of examining and evaluating products, components, or materials to ensure they meet specified requirements and standards. It doesn’t have a direct influence on the production process. The products are checked by inspectors to ensure they are fit for mass production and shipment to customers. The findings from the inspection are consolidated into an inspection report, which provides an overview of whether the product meets the specified requirements and standards.

Quality control is defined by the ISO 9000: “A part of quality management focused on fulfilling quality requirements.” Quality control refers to the process of ensuring that products, services, or processes meet established quality standards and specifications.

The main objective of quality control is to ensure that the final product or service meets customer expectations in terms of quality, performance, and reliability. This not only helps to build customer loyalty but also helps businesses to enhance their brand reputation and increase market share.

Companies use a set of quality control activities that involves monitoring and controlling the production process to assess whether or not the product is fit for its purpose and defined standards. These activities often include quality inspections.?

The Importance of Quality Inspection

It is virtual for buyers to maintain the product quality, as it directly impacts customer satisfaction and brand reputation.

Quality inspection determines and verifies the quality of the products to ensure that delivered products are the same as expected, monitors and supervises the manufacturing process to avoid shipping delay.

Quality inspection controls quality, reduces manufacturing costs and rejection losses, and assigns causes for the production of a defective product. Quality inspection during the product manufacturing process ensures standardization and uniformity for controlling the product quality by comparing it with the standards and specifications.

Quality inspection is also conducted to reveal the product defects, style, functions, workmanship, and packages and reported to the buyers for deciding whether pass or reject product release.

What are the 4 Types of Quality Inspection?

Quality inspection checks for quality and identifies ways to minimize manufacturing costs, reduce scrap losses, and mitigate causes of defective work. There are mainly 4 types of inspection in quality control to assess the quality of products, ensuring consistent production processes and effective control systems:

Initial Production Check (IPC)

During Production Check (DUPRO)

Final Random Inspection (FRI)

Loading Supervision (LS)

These four types of inspection are carried out at different stages of the product manufacturing process. Based on your specific requirements and industry, you may find that one or all of these four inspection types are of the essence.

1. Initial Production Check (IPC)

The Initial Production Check (IPC) takes place at the beginning of the manufacturing process to assess the production readiness of a factory and ensure that initial production runs meet the buyer's specifications and quality standards. It is the first step in ensuring that your supplier will consistently manufacture good quality products.

By conducting an IPC, buyers can proactively address any issues early in the production process, minimizing the risk of defects, delays, and quality problems in the final product.

2. During Production Check (DUPRO)

During Production Check (DUPRO) is conducted when 30%-50% of goods are completed so that to ensure consistent quality in the manufacturing process. It allows you to identify any issues or defects early on and enables manufacturers to take corrective actions before large quantities of defective products are produced.

DUPRO is especially valuable for products that are in continuous production and have stringent quality requirements. Conducting DUPRO can minimize the risk of producing substandard goods and ensure that the final products meet customer expectations, thereby reducing delays and rework.

3. Final Random Inspection (FRI)

Final Random Inspection (FRI, known as pre-shipment inspection) is the most popular and commonly used quality inspection method. Final inspection takes place when your production is 100% completed and at least 80% of goods packed and seated in shipping cartons for verification of your purchase specifications.

Checklists of the final random inspection:

-Inspection conditions: product status, carton stacking, shipment quantity, etc.

-Packaging and assortment: carton packing, product packing, and assortments such as -color/styles/sizes.

-Shipping marks: printings, warming and symbols.

-Labeling: labels, markings, etc

-Product conformity: Style, materials, colors.

-Workmanship: appearance, basic functions.

-On-site test: barcode verification, measurements, weight, functionality, etc.

Final inspection is an important step in the quality control process that ensures the production complies with the specifications of the buyer.

4. Loading Supervision (LS)

Loading Supervision (LS) is the final but crucial step in the quality control process that is properly preparing batches for shipping to destination markets.

Container loading inspections is usually performed at the factory, forwarders port to verify count to ensure your products are loaded correctly. Inspectors will supervise throughout the whole process and ensure your products are handled professionally to guarantee their safe arrival to their final destination. Also, this inspection confirms products are consistent with the packing list of the client, ensures the correct amount of different styles, sizes, quantities, and verifies all the product information, and packaging compliance.

Product inspections play a crucial role in reducing product returns due to defects or poor quality, which can significantly impact your profit. By choosing the right inspection service, you can effectively reduce return rates, maintain profitability, and ensure customer satisfaction.

Inspections vs Audits vs Lab Tests: What’s the Difference?

Inspections: Inspections involve a thorough examination of a process, system, product, or facility to ensure compliance with specific criteria or standards. The primary aim is to identify defects, deviations, or non-compliance that can impact the quality, safety, or functionality of the item being inspected.

Product inspections typically take place at the factory where inspectors check the products for conformity to requirements. The frequency of inspections will vary depending on the industry, product, or process being inspected.

Audits: Factory audits are the assessment for production capability and performance of a factory against proven quality principles. Every production site needs reliable manufacturing and quality control systems to ensure customers are satisfied with their products.

Audits are performed to ensure that a company’s internal processes, controls, and systems are compliant with established standards, industry regulations, or company policies. They are often used for quality management, environmental performance, and documentation of health and safety.

Lab tests: Lab tests are another way to help enter the destination markets through physical and chemical testing for your products. Product testing typically occurs in a specialized lab by using advanced equipment setting to verify product safety, compliance, or performance. You might test your products to check for harmful chemicals, comply with regulations, or simulate repeated use.
