15.0 FRAGRANCE ADVERTISING SAMPLE

A fragrance advertising sample (39 USC 3001(g)), i.e., any

matter normally acceptable in the mail but containing a

fragrance advertising sample, is permitted in the mail only if

it is sealed, wrapped, treated, or otherwise prepared in a

manner reasonably designed to prevent individuals from being

unknowingly or involuntarily exposed to the sample. A

sample meets this requirement if it uses paper stocks with a

maximum porosity of 20 Sheffield units or 172 Gurley-Hill

units treated exclusively with microencapsulated oils, and if

the sample is produced so that it cannot be activated except

by opening a glued flap or binder or by removing an overlying

ply of paper.
