Inspection rules
6.1 Cinnamon oil should be inspected by the technical inspection department of the manufacturer. The manufacturer should ensure that all products shipped meet the requirements of this standard, and each batch of products shipped should be accompanied by a quality certificate. The content includes: manufacturer name, product name, production date, batch number, net weight, product quality compliance certificate and number. 6.2 The acceptance unit has the right to verify according to this standard, and each batch number shall be accepted once. 6.3 If one of the indicators in the acceptance result does not meet the requirements of this standard, a sample can be taken from 2 times the amount of packaging for re-inspection. If the re-inspection result still fails to meet the indicators, the batch of products cannot be accepted. 6.4 When the supply and demand parties have objections to the product quality, they can negotiate to resolve or ask a third party for arbitration. 7 Packaging, marking, transportation, storage
7.1 Cinnamon oil is packaged in aluminum barrels (if the user has special needs, tin barrels can also be used). The product name, manufacturer name, batch number, gross weight, net weight, factory date and this standard number are marked on the outside of the package. 7.2 This product should be stored in a cool, dry and ventilated place. The room temperature should not exceed 35℃ to prevent contamination by foreign air and prevent sun and rain during transportation. The flash point of cinnamon oil is about 130℃.
7.3 Packaging The allowable error of the weight of each barrel shall not exceed ±3%, and the weight of each batch shall not be less than the specified net weight. Under the condition of meeting the specified storage conditions, intact packaging and unopened, the shelf life is one year. Gas chromatography conditions:
