01
Items to be inspected
Checking of orders and delivery orders, physical comparison, appearance inspection (bending, oxidation), quantity
Confirmation of RoHS products and other environmental products (when confirming the label)
Inspection records: Yes (stored for 5 years)
Batch inspection record: Yes
Qualified inspector: Only qualified personnel who meet our regulations can conduct inspections. When working, they will wear anti-static clothing, anti-static slippers, and install anti-static wristbands on anti-static pads, and prohibit touching goods with bare hands
02
Warehouse Management
How to store inventory: The storage location is a normal air-conditioned office in an anti-static room.
Model and storage quantity control: recorded in the inventory management ledger
Expiry management method: In principle, the shelf life is two years.
Operation such as storage of expired products: stored on a special shelf for defective products. When defective products are found, they are recorded in the inventory as ready for disposal, and those found one year later are discarded at the end of the year.
Checking items at the time of shipment: Match the receipt of product name, quantity and packing specification with the actual product.
03
Shipment inspection
How to check: All products are inspected
Inspection items: Acceptance inspection confirmation, matching the actual product, address confirmation, other confirmation items (if any)
Inspection records: Yes (stored for 5 years)
Packaging materials: use of anti-static bags, vacuum packers, and vacuumizer
Inspection Process
Our quality assurance process embodies the fundamental focus on quality that LITUOXIN has built into its inspection system.
Components are inspected, measured, examined and tested from the inside out to ensure that the product meets the customer's standards.
