My issue with that is, were your package checked (and yes, they can, and DO *adjusts tin-foil hat*), you OR the company could get busted for smuggling.
They got my grandpa for trying to import a certain brand of Absinthe (NC is VERY strict on the liquor laws-no crossing of state lines without a certain permit, as I understand it, which MAY be wrong, by the way). Package was marked as "Fragile, do not open" and listed as from his cousin. HEFTY fine (he was lucky-no prison time).
If they're that interested in keeping PVs down in Singapore... I would advise against that plan of attack.
Just my two cents.
