I sense that Michael is well-aware of this, based on his choice of wording, but all the pre-CITES N.kaiseri are technically illegal under the Lacey Act, because there have been virtually no legal exports of them from Iran. Illegal from the source=illegal under the Lacey Act. And like other CITES-1 animals, or animals of probably-illegal origin [eg. Australian CITES species, which require USFWS export permits, but likely never arrived legally], it's not likely that USFWS will ever grant export paperwork for them.
As for other imports and exports, he is also correct. 1) eggs are animals and require all the same papers and procedures.
USFWS regulations make it difficult to move many animals between the USA and anywhere else, as those procedures must be followed, regardless of the laws of other countries. Many countries have few restrictions on the shipping or import and export of herps [eg., Canada, some European countries], but some have laws similar to the Lacey Act [eg., Canada's WAPPRIITA]. So while you can mail eggs and salamanders to and from these countries, you can't do so to or from the USA. Shipping by other methods may be legal, but failing to follow the proper procedures of any country is a violation of federal law in both the USA and Canada. So while you might follow your own domestic laws [or think you are], you could commit federal offenses by not accommodating foreign regulations as well.
