Suppose the next time you're a painter bringing in a painting of yours into the country. Next thing you know they are accusing you of smuggling. Is the solution to hire people with background in arts?
This actually happened to me when I brought my wife's paintings from London to Russia 3 years ago.
Answering your question. You know, I worked as CITES expert on customs back 15 or 16 years. No sane customs officer can distinguish between crocodile skins. This is why there was (and still is) institution of advisors.
