7.1 Whether the finished product of citronella can be free from sound inspection by the inspection department of the production plant, and the "stop production" should ensure that the products leaving the factory do not meet the requirements of the load table. Each batch of products should be accompanied by a quality certificate, including: manufacturer, name, product name, trademark, production date or batch number), net vertical, product quality certification and this standard, and the requirements of this standard shall be shortened. Each batch shall be inspected and accepted separately. -9

7.3 For each batch of packaging, three boxes (cans) shall be selected for less than 100 barrels (cans), and three bottles (cans) shall be selected for more than 100 barrels (cans). After unpacking, the appearance inspection should be free of moisture and impurities. After vibrating, mix thoroughly, and then use a glass tube to absorb 50-1 ml of sample each time, inject into the sample mixer and mix evenly: put into two clean glass bottles with different mixing devices, and mark the manufacturer name, product name, batch number, quantity and validity period on the bottles. One bottle is used for inspection, and the other bottle is kept for reference. 4 If there are indicators in the acceptance results that do not meet the requirements of the technical standards, the company will work with the manufacturer to re-examine the samples. If there are indicators in the re-test results that are unqualified, the batch of products cannot be released for inspection. 7.5 The supplier can make a second inspection for the product quality, and the cost will be borne by the supplier.
8 Marking. 8.1 The whole citronella should be packed in glass bottles, boxes or containers (tins). The packaging should include: product name, manufacturer name, trademark, batch number, net weight, production date, standard and flammable material mark. If the shipping unit has special requirements, the company will discuss with the manufacturer.
8.2 The wood products should be stored in a well-ventilated, cool warehouse to prevent contamination by foreign air and away from fire sources. The transportation should comply with the regulations of relevant departments.
