Essential Steps in a Pre-Shipment Inspection
Pre-Shipment Inspection (PSI), also known as Final Random Inspection, is the most common inspection type to confirm the whole shipment’s quality level. It normally requires the production to be completed and at least 80% of goods packed into cartons.
Inspection Visit
The first step in the pre-shipment inspection procedure is the inspection visit. This includes the planning of the inspection on the site at which it will be carried out. The inspection procedure is laid out and the process is decided.
Verify Quantity
The next step is quantity verification. The inspectors count the cartons to verify the quantity and ensure that the right number of products and boxes are sent to the correct destination.
Random Sampling
The next step is random sampling. In this step, a statistical sampling procedure like the Acceptance Quality Limit (AQL) sampling method is used to determine the number of pieces to examine in each batch/carton. Post this, the products are pulled from the final batch.
Product-Specific Testing
After samples are taken from the production batch, special testing is done to determine the quality of the products. This is usually based on the category. For example, if the goods are electronic, the charging ability, time taken to charge, etc. will be carried out. These tests vary as per the products and some tests can be time-consuming, hence inspectors begin with these.
Packaging and Label Checks
The next step is to check the packaging and labeling of the goods. Here, the inspectors check the labels of the packaging and identify any miss labeling that can get you in trouble. Also, the packaging is verified by checking the card in size, weight, sealing methods, etc.
Visual Inspection
After this, the samples are visually inspected to check for obvious defects like any paint that might be peeling, missing screws, etc. The defects are classified as minor, major, or critical and this classification is decided beforehand.
Functional Testing
In the next step, the products are checked by using them to see if they work as intended. For example, if you are inspecting the dining table, the lens must be sturdy and firm, if you are inspecting a hair clip, the screws must be in place and it must not break when tying your hair, etc.
Physical Verification
Under the physical verification step, the product is checked for height, weight, length, breadth, etc. to ensure that the physical criteria areas mentioned. Here, tools like Vania calipers, measuring tapes, weighing scales, etc. are used to confirm actual measurements.
Barcode Verification
After the physical requirements, a barcode verification is done so that all information is accurately captured in the barcode and no roadblocks to phase during shipping. It is also checked if it is properly placed on the box and readable.
Inspection Report
The final step after all the inspection steps in the report. A report is prepared approving or to reject the inspection. It contains the process and results of each of the tests that are conducted
