According to China's "Regulations for the Supervision and Administration of Medical Devices", for the manufacturing enterprises, they should mark each piece of medical devices manufactured in accordance with the relevant national laws, regulations and standard requirements, and individual marking should be consistent with the enterprise's internal quality assurance records, so the date of production marked on the body of the medical device should be consistent with the enterprise's internal records. Otherwise, enterprises will face penalties from relevant regulatory authorities.
Medical devices may also be in violation of the regulations if the date of manufacture labeled on the outer box of the device does not match the date labeled on the body. The production date on the outer box is usually for the convenience of consumers to view, under the premise of ensuring the authenticity of the manufacturer can make reasonable adjustments. However, if the enterprise intentionally tampered with or fictitious production date, then it may be suspected of fraud, false advertising and other illegal acts.
