Regulations Governing Registration and Application for Inspection of Commodities Article 5

An applicant shall place a domestic sale registration number on the body of commodities that require an application for domestic sale inspection registration in advance, in accordance with Article 19 of the Act. However, if the body of the commodity is too small to accommodate such marking, the number may be marked on the smallest package of the commodity. Where it is allowed for an applicant to imprint the inspection marks, such marking is not required.
