Every manufacturer with authority to maintain manufacturer representatives under Section 4f of this Act shall keep within Illinois, at his business address identified under Section 4f of this Act, complete and accurate records of cigarettes purchased, sold, or otherwise disposed of, and shall preserve and keep within Illinois at his business address all invoices, sales records, copies of bills of sale, inventory at the close of each period for which a report is required of all cigarettes on hand, and other pertinent papers and documents relating to the purchase, sale, or disposition of cigarettes. Every sales invoice issued by a manufacturer representative to a retailer in this State shall contain the manufacturer's manufacturer representative license number. All books and records and other papers and documents that are required by this Act to be kept shall be kept in the English language, and shall, at all times during the usual business hours of the day, be subject to inspection by the Department or its duly authorized agents and employees. The Department may adopt rules that establish requirements, including record forms and formats, for records required to be kept and maintained by manufacturers with authority to maintain manufacturer representatives under Section 4f of this Act and their manufacturer representatives. For purposes of this Section, "records" means all data maintained by the manufacturers with authority to maintain manufacturer representatives under Section 4f of this Act and their manufacturer representatives, including data on paper, microfilm, microfiche or any type of machine sensible data compilation. Those books, records, papers, and documents shall be preserved for a period of at least 3 years after the date of the documents, or the date of the entries appearing in the records, unless the Department, in writing, authorizes their destruction or disposal at an earlier date. At all times during the usual business hours of the day, any duly authorized agent or employee of the Department may enter any place of business of the manufacturers with authority to maintain manufacturer representatives under Section 4f of this Act and their manufacturer representatives, or inspect any motor vehicle used by a manufacturer representative in the course of business, without a search warrant and may inspect the premises, motor vehicle, and any packages of cigarettes therein contained to determine whether any of the provisions of this Act are being violated. If such agent or employee is denied free access or is hindered or interfered with in making such examination as herein provided, the ability to maintain marketing representatives in Illinois may be withdrawn by the Department.
