When you purchase a pack of cigarettes in the United States, the regulations governing what is in that pack depend significantly on where it was made.
Domestic tobacco manufacturers are required to register with the FDA, submit product listings that document each product's ingredients and design, follow current Good Manufacturing Practice standards, and report adverse events. Foreign manufacturers who want to sell tobacco products in the United States have not been subject to the same requirements — because while Congress gave the FDA authority to require foreign registration in Section 905(h) of the Tobacco Control Act, the agency had never issued the implementing regulations to make that requirement operative. Until now.
