Answer 1

When mass-importing, (there should be specified amounts on what exactly is SMALL-MEDIUM-LARGE-COMMERCIAL importation)...

At the commercial level not everything can be simply flown in. There must be either a specified percentage of the product that must be shipped by boat to be filtered through and inspected by port customs and police. It's a general protection against the mass-importation of illigal substances, because for some reason the government feels that boats are more secure than planes... Or possibly it's just an old stature that needs to be changed.
