According to a 1930's article in the Tampa Times:
"The practice of bringing back perfumes from Cuba for all your friends is just about a thing of the past now, under the terms of the new (Republican) tariff law. Importations of all foreign manufactured perfumes are forbidden and Tampans returning recently from Havana were permitted to bring in only a single bottle of any one brand, and then only with the seals broken and other evidence of the perfume's source destroyed. Messrs. Chanel, Cot and others -address Paris - will be required to open brand factories in the US to manufacture their famous scents."
