5.1 General

Products must pass the inspection of the manufacturer's quality inspection department and be accompanied with a quality mark before they can leave the factory.

5.2 Classification of inspections

Product inspection is divided into exit-factory inspection and type inspection.

Product inspection items and categories are as shown in Table 2.

When the type inspection item is unqualified, it shall randomly take double quantity of samples for re-inspection of the item. If it still fails, the type inspection is judged as unqualified. If the type inspection fails, the acceptance of this model of product shall be stopped, and production shall stop. At the same time, it shall analyze the causes and take measures; it can restore production and acceptance after new type inspection is qualified.

6.1 Marking and packaging

6.1.1 The product packaging bag that has passed the inspection shall be marked with the name, code, trademark, brand, batch number (or production date), standard number, weight, manufacturer (including factory address, telephone, postal code), the sign of “avoid heat and moisture”.

6.1.2 Each batch of products delivered shall have a product inspection report and a certificate of conformity.

6.1.3 The product uses moisture-proof inner packaging of aluminum-plastic

composite film, Kraft paper or non-woven outer packaging, or a packaging bag negotiated between the supplier and the purchaser. The net weight of each bag is 25 kg or other weight approved by both the supplier and the purchaser.

6.2 Transportation

When transporting the product, do not expose it to the sun or rain; keep the product dry, clean, complete, free from pollution.

6.3 Storage

The product shall be stored in a clean, dry, cool and ventilated warehouse.
