I want to order baby carriers in wholesale amount to israel. I first want to know how much tax I will have to pay. How do I calculate that? (not talking about income tax)

No, you are talking about excise taxes and possibly import tariffs.

Unfortunately, I do not think ANYONE who monitors this forum can provide you with any answers.

YOu can get some information on the website of the Israeli Tax Authority.
The Hebrew site is here:
http://ozar.mof.gov.il/taxes/mainpage.htm
Theey also have an English site, but it's not very good. The link is on the bottom right of the Hebrew site.
Look under
מכס
יבוא ויצוא מסחרי

Sorry, the Hebrew didn't get encoded well.
It should be
Meches
Iawo mischari
