Same here.. my %tariffData = ();

A reference of %tariffData is returned to the caller.

I guess your initial subroutine would be like this.
$ref_tariffData = func();
subroutine func returns refernce to a hash.
If you want to use it in another subroutine. simply pass the reference
of that hash to the subroutine.
func2($ref_tariffData);
sub func2 {
my ($ref_hash) = @_;
foreach my $key ( keys %$ref_hash ){
print "$key: $ref_hash->{$key}\n";
}
}

You can pass the whole hash but only if you are passing one hash.
return %hash; # OK
return %hash1, %hash2; # May not be OK
Please read the following perldocs:
