Contact the supplier immediately to investigate the cause. If there is feedback that the supplier's parts are unmarked, please contact the supplier immediately to investigate the reason. If the supplier makes a mistake, the supplier will arrange for someone to go to the company to affix the label, or entrust someone else to do it. Products without labels need to be isolated and placed separately as unqualified products and will not be put into storage for the time being. If the supplier does not handle it, the product will be returned. According to regulations, all pre-packaged food must have labels. If there is no label, it is an unqualified product.
