February 15, 2007. As stated in section II.D, we interpret “as of” to mean “on.” Accordingly, the information submitted should demonstrate (individually or collectively) that the tobacco product was commercially marketed (other than exclusively in test markets) in the United States on February 15, 2007. If you cannot provide documentation specifically dated on February 15, 2007, FDA suggests you provide documentation of commercial marketing for a reasonable period of time before and after February 15, 2007.
Examples of such information may include, but are not limited to, the following:
• dated copies of advertisements
• dated catalog pages
• dated promotional material
• dated trade publications
• dated bills of lading
• dated freight bills
• dated waybills
• dated invoices
• dated purchase orders
• dated customer receipts
• dated manufacturing documents
• dated distributor or retailer inventory lists
• any other document you believe demonstrates that the tobacco product was commercially marketed (other than exclusively in test markets) in the United States as of February 15, 2007
FDA will consider and evaluate all of the information provided on a case-by-case basis.
