When a company purchases items from a vendor, a quality inspection is usually necessary. There are various quality inspections in supply chain such as inspections during the manufacturing process, inspection of the final finished product, and inspections while the items are stored in the warehouse.

1. Importance of Inspection of Purchased Items

The quality inspection occurs so that a company can verify that the product is within certainly prescribed tolerances in order for the product to be useful. For example, a company may purchase a paint additive to be used in their manufacturing process, but before it can be used, it has to be inspected to see that the chemical and physical composition of the additive is within the tolerances to be used in the process.

When a purchasing agreement is made with a vendor, it will define the characteristics of the product that are to be inspected and the tolerances that would be allowed. If the item is received and found to have characteristics outside those agreed upon in the purchasing contract, then the company can have the chance to return the item to the vendor.

2. Inspections at the Vendor’s Facility

The quality inspection can also take place at the vendor’s facility. Some companies prefer to perform the inspection before the items are transported to their manufacturing plant. However, the inspections can incorporate more than inspections of the product, but also inspections of the production facility, equipment, documentation, manufacturing processes, and storage facilities.

These quality inspections are important when purchasing agreements are being negotiated. Some vendors may have ISO 9001:2000 Quality Management Standards (QMS) certification which offers customers a greater sense of expected quality and may lessen the requirement of regular inspections.

3. Inspections on Production Line

When a manufacturing company creates finished goods, it cannot afford to wait until the items are coming from the end of the production line before they are inspected. Production issues need to be addressed early in the process in order to correct problems. This can reduce the loss of raw material and reduce the overall time that the production process is shut down. In every type of industry, there is a process where quality inspections can be performed during production. 

For example, in the chemical industry, there should be inspections during the process to test the item at certain stages to ensure that the product is within the manufacturing tolerances. In the manufacturer of consumer products, many inspections are performed so that components are tested as the final product is being assembled to ensure that the finished product will be fault free.

4. Inspections for Finished Goods 

When the finished item comes off the production line it should be inspected to ensure that it conforms to the quality standards of which is to be sold. The final check could include not only the finished goods themselves but the packaging used to ship them to the customer. If the packaging is damaged or incorrectly labeled, then this could require the item to be reworked or scrapped.

5. Inspections in Client’s Warehouse

Finished goods can be sent directly to the client’s warehouse before it is sold. For some items, storage for a period of time can alter the characteristics of the product. For example, some products are susceptible to degradation by heat or cold.

Finished goods that are produced to be within certain chemical tolerances can be affected by environmental conditions so that some characteristics are no longer within the stipulated tolerances. Inspections in the warehouse can ensure that the finished goods are still able to be shipped to customers.
