Health certificates are mainly aimed at employees who have direct contact with food, drinking water, public places and other specific industries, and need to prove that they have corresponding health qualities. The staff in the logistics department generally do not have direct contact with these industries, so there is no need to apply for a health certificate. If the staff of the logistics department need to contact specific industries such as food and drinking water, or work in specific places, such as canteens and restaurants, they need to apply for health certificates in accordance with relevant regulations.
