When discovering cases of violation, the inspection personnel should make a record on the spot by filling out a Violation Case Report, which states in detail the name and address of the commodity holder, the name and address of its responsible person, the names, specification and quantities of the goods, their purchase price, the origin of the goods, and the details of the violation, and ask the commodity holder or an on-site staff member to view and sign the report. The competent tax authority will handle the case according to the law.
