The pre-shipment Inspection takes place when the merchandise is 100% completed, and at least 80% of the products are packed, marked. Our inspectors randomly draw some samples from finished goods, based on statistical random sampling technique, commonly known as ANSI/ASQC Z1.4 MIL-STD-105E, BS6001, DIN 40080, ISO2859 or NFX06-022, to verify that the finished shipping lots conform to the client’s specification, order, L/C, reference samples, etc. 

The main aspects checked for PSI:

·Quantity check 

·Appearance check : size, color ,shape, to check if there is dirt, scratches, burr, etc 

·Style, color & material check 

·Workmanship check 

·Function/safety check 

·Size measurement if needed 

·Package details check: shipping marks, label, hangtag, manner of packing, packing qty, safety of packing, etc 

·Related on-site test: it depends on the product to decide which on-site tests will be applied, such as size checking, function checking, drop test, etc.
