Here is one thing you can do to find out.
Go to
www.usps.com and "pretend" that you
are looking for an international rate for a
package. Choose the country and just put
any amount in for the weight ... then, when
it takes you to your rate page, at the top
of the page you will see a link that says
something about "see restrictions and
information for (the country)" ... click on
that and you can read all the details of
what you can send and can't send.
Remember that a soap is not only a soap
if it has any active ingredients in it ... it is
then considered to be a cosmetic. For instance,
the U.S. cannot ship cosmetics into some
countries, etc.
I hope this helps!
