My thinking on it is that small packages aren't an issue. The last time I sent a package to Sweden, she asked about the contents, I told her a small decant of perfume, she pursed her lips, wrinkled her brow and said, "we'll call it cosmetics." I don't know if the laws have changed, but I know many companies in the past used the USPS but had to have a permit to do so. Yves Rocher, StrawberryNet and Jeanne Arthes still ship via the postal service. Of course, the only other option for the latter two would be by boat. So, if flammability is the issue, are certain precautions taken when they are aware of the contents? I guess I'll just depend on the discretion of the postal employees. They obviously know what's safe and, being federal, I think they pretty much walk a thin line. Good question, though.
