Not quite how it works. (At least, not in the US).
Firstly, not just any FBO is a point of entry.
Which brings us to the second point, the entire reason for designated points of entry is so that the customs officials can be on site already. As in, assigned to that FBO. Now at times specialists have to be sent out. (Think exotic or rare animals or biological/agricultural products.) But if that happens, your freight, and maybe even you, are quarantined and your freight isn't going anywhere any time soon. Believe me.
Most important, and relevant in this context is the third issue. Which is the fact that arrivals are met by customs officials and passengers and cargo are always subject to the same inspections/regulations as they are at any commercial airport.
So the original question is valid, how are they handling customs at the scale they're hoping to achieve in a fashion any faster than anyone else?
FBO = fixed base operator = private jet terminal or service provider at airports that caters to general aviation (non-commercial) flights. FBOs provide services like fueling, hangar space, and sometimes even customs clearance for international flights.
So they build operate their own airship FBOs? Honestly seems like the smaller hurdle to jump if all the engineering problems are solved, they will find a way to navigate this too. It’s a bit naive to assume they will comply with existing constraints versus defining what the airship industry would need. They won’t roll this out globally on day one, the largest and most obviously profitable areas will be source/destinations are probably easy to guess. They could even do their proof of concept it less regulated markets before coming to the US later. Plenty of room to solve these problems later.
