ADCAE Dealer from the UK "Regrets"

An anonymous ADCAE dealer based in the UK announces on his or her website that although the CCPIA allows import of antiquities from countries with MOUs, on the basis of TWO different kinds of paperwork indicating licit export from the source country:

(NO collecting history stated)  Regretfully, we are unable to sell this item to American clients due to US import restrictions.

Wot, no paperwork?

("Previously in a German private collection and supplied with a thermoluminescence certificate from Laboratory Ralf Kotalla, Haigerloch, Germany, dating from November 1981") Regretfully, we are unable to sell this item to American clients due to US import restrictions.
Wot, no other paperwork? 

("Ex German private collection") Regretfully, we are unable to sell this item to American clients due to US import restrictions.
Wot, no paperwork?

("Previously in a private Florida collection")  Regretfully...
wot, no paperwork? 

("Previously in a private Florida collection") Regretfully we are unable to sell this item to American clients due to US import restrictions.
Wot, no paperwork here either?

("Previously in a private Florida collection") Regretfully we are unable to sell this item to American clients due to US import restrictions.
No paperwork then? 

("Previously in a New York State private collection") Regretfully, we are unable to sell this item to American clients due to US import restrictions.
Paperwork deficiency perhaps?

(NO collecting history stated) Regretfully, we are unable to sell this item to American clients due to US import restrictions.
Another one without da paperwerk?

(NO collecting history stated) Regretfully, we are unable to sell this item to American clients due to US import restrictions.
Go on, surprise us, you've got paperwork for this one but this one's too nice to let go?

There are another two pages of this nonsense, misusing "regretfully" as a sentence adverb - the dealer presumably means "regrettably", though they may now - too late - be regretful if they bought items without the paperwork which would prevent their free sale.  So how is it this dealer claims to be following ADCAE Code of Ethics, if he has no documentation of the collecting history that would allow the production of the very basic information required to import these objects under the terms of the US CCPIA? Where's the due diligence? Interestingly, the dealer does not say if they'd ship to Peru.
