6 Inspection rules
6, 1 Bayberry should be accompanied by some of the finished products The factory inspection department is responsible for the inspection. All products will meet the requirements of this standard. Each batch of factory products shall be accompanied by a quality certificate including: manufacturer name, product name, production period (with batch number), product quality certificate, and product number. 6.2 The acceptance unit shall inspect the product quality in accordance with the provisions of this standard to see if it meets the requirements of the standard. Each batch number shall be inspected once, and each batch number shall be inspected separately. 5.3 Each batch of packaging shall be less than 100 pieces, and 1 piece shall be taken out of 100 pieces. When sampling, check the moisture and impurities of the components. Then, take 50-100m1 of the sample from each piece in a glassware and separate them into small pieces. The name of the manufacturer, product, batch number, and acceptance period can be clearly stated on the bottle. One bottle shall be inspected for quality and retained for future reference. 6.4 If there are any items that do not meet the requirements of the inspection results, the company may re-test with the manufacturer. If the inspection results are still unqualified, the batch of products cannot be inspected. E.5 If the buyer has any objection to the product quality, the two parties may negotiate to resolve it or invite a legal inspection agency for arbitration. The party shall be responsible for the cost of the inspection. 1. The packaging of aluminum salicylate shall be selected by the customer. The packaging shall include: manufacturer name, product name, trademark, batch number, net weight, surface area, factory month and semi-standard number. If the ordering unit has special requirements, it can be coordinated with the production unit. 2. This product should be stored in a dry, ventilated, cool warehouse, away from fire sources, and should not be in contact with acid or bottled separately.
