I imagine the form is needed by all people / resellers when buying directly from the manufacturers.... especially a foreign manufacturer.
It really isn't a big deal, it is more of a " I will not resell this product outside of the USA."
Just like when you acknowledge the same thing from the various distributors.... "Agreeing to the terms of service" etc...
Quite honestly .... I would phone them again and double check.
I really think it is more of a "Cover my keister" thing for them.
Google search....
